Objective. To investigate the dissipation and outcomes of pulmonary lesions at the first follow-up of patients who recovered from moderate and severe cases of COVID-19. Methods. From January 21 to March 3, 2020, a total of 136 patients with COVID-19 were admitted to our hospital. According to inclusion and exclusion criteria, 52 patients who recovered from COVID-19 were included in this study, including 33 moderate cases and 19 severe cases. Three senior radiologists independently and retrospectively analyzed the chest CT imaging data of 52 patients at the last time of admission and the first follow-up after discharge, including primary manifestations, concomitant manifestations, and degree of residual lesion dissipation. Results. At the first follow-up after discharge, 16 patients with COVID-19 recovered to normal chest CT appearance, while 36 patients still had residual pulmonary lesions, mainly including 33 cases of ground-glass opacity, 5 cases of consolidation, and 19 cases of fibrous strip shadow. The proportion of residual pulmonary lesions in severe cases (17/19) was statistically higher than in moderate cases (19/33) ( χ 2   =   5 . 759 , P < 0.05 ). At the first follow-up, residual pulmonary lesions were dissipated to varying degrees in 47 cases, and lesions remained unchanged in 5 cases. There were no cases of increased numbers of lesions, enlargement of lesions, or appearance of new lesions. The dissipation of residual pulmonary lesions in moderate patients was statistically better than in severe patients (Z = −2.538, P < 0.05 ). Conclusion. Clinically cured patients with COVID-19 had faster dissipation of residual pulmonary lesions after discharge, while moderate patients had better dissipation than severe patients. However, at the first follow-up, most patients still had residual pulmonary lesions, which were primarily ground-glass opacity and fibrous strip shadow. The proportion of residual pulmonary lesions was higher in severe cases of COVID-19, which required further follow-up.

Abstract Background: Previous studies have focused on the clinical characteristics of hospitalized patients with the novel 2019 coronavirus disease (COVID-19). Limited data are available for convalescent patients. This study aimed to evaluate the clinical characteristics of discharged COVID-19 patients.Methods: In this retrospective study, we extracted data for 134 convalescent patients with COVID-19 in Guizhou Provincial Staff Hospital from February 15 to March 31, 2020. Cases were analyzed on the basis of demographic, clinical, and laboratory data as well as radiological features. Results: Of 134 convalescent patients with COVID-19, 19 (14.2%) were severe cases, while 115 (85.8%) were non-severe cases. The median patient age was 33 years (IQR, 21.8 to 46.3), and the cohort included 69 men and 65 women. Compared with non-severe cases, severe patients were older and had more chronic comorbidities, especially hypertension, diabetes, and thyroid disease (P<0.05). Leukopenia was present in 32.1% of the convalescent patients and lymphocytopenia was present in 6.7%, both of which were more common in severe patients. 48 (35.8%) of discharged patients had elevated levels of alanine aminotransferase, which was more common in adults than in children (40.2% vs 13.6%, P=0.018). A normal chest CT was found in 61 (45.5%) patients during rehabilitation. Severe patients had more ground-glass opacity, bilateral patchy shadowing, and fibrosis. No significant differences were observed in the positive rate of IgG and/or IgM antibodies between severe and non-severe patients.Conclusion: Leukopenia, lymphopenia, ground-glass opacity, and fibrosis are common in discharged severe COVID-19 patients, and liver injury is common in discharged adult patients. We suggest physicians develop follow-up treatment plans based on the different clinical characteristics of convalescent patients.

Abstract Purpose: Regardless of professional societies agreed that CT screening inconsistent with recommendation leads to radiation-related cancer and unexpected cost, many patients undergo unnecessary chest CT before treatment. The goal of this study was to assess the overuse of Chest CT in different type of patients.Methods: Data on 1853 patients who underwent pulmonary resection from May 2019 to May 2020 were retrospectively analyzed. Data collected include age, sex, follow-up time, density and size of nodules and frequency of undergoing Chest CT. Pearson χ2 test and logistic regression were conducted to compare the receipt of CT screening.Results: Among 1853 patients in the study, 689 (37.2%) had overused Chest CT during follow-up of the lung cancer. This rate was 16.2% among patients with solid nodules, 57.5% among patients with pure ground glass opacity (pGGO), and 41.4% among patients with mixed ground glass opacity (mGGO) (P<.001). 50.7% in the “age ≤40” group, 39.8% in the “41≤age ≤50” group, 38.7% in the “51≤age ≤60” group, 32.3% in the “61≤age ≤70” group, 27.8% in the “>70” group underwent unnecessary CT (P<.001). Female get more unnecessary CT than male (40.6% vs 32.8%, P<.001). Factors associated with a greater likelihood of Chest CT is the density of nodules (odds ratios [ORs] of 0.53 for mGGO; 0.15 for solid nodule, P<.0001, vs patients with pGGO).Conclusion: roughly 37% patients with pulmonary nodules received Chest CT too frequently despite national recommendations against the practice. Closer adherence to clinical guidelines is likely to result in more cost-effective care.

Objective: The study aimed to describe the clinical and imaging course of reverse transcriptase polymerase chain reaction) confirmed coronavirus disease (COVID-19) patients who are asymptomatic at admission. Methods: This was a retrospective observational study. Severe acute respiratory syndrome coronavisrus-2 (SARS-CoV-2) positive cases that were asymptomatic at admission were retrospectively enrolled. Specific clinical information, laboratory test results, chest CT imaging features and outcome data during hospital stay were collected and analyzed. Results: 137 non-consecutive asymptomatic patients with reverse transcriptase polymerase chain reaction confirmed COVID-19 were enrolled in the present study. On admission, patients had no symptoms but chest CT findings were present in 61/137 (44.5%). Ground glass opacity (48, 78.7%) followed by ground glass opacity with crazy-paving pattern (9, 14.7%) were the commonest type of opacities with posterior, peripheral predominance and lower zone predilection. Among the initial CT positive group of 61 patients, follow-up imaging revealed progression of pulmonary opacities in 13/61 (21.4%), complete resorption in 21/61 (34.4%), partial resolution in 22/61 (36%) and no change in 5/61 (8.2%). The patients in progression group (54 ± 19.7 years) were older and had higher frequency of co-morbidities (46.2%) compared to the other three groups (10.4%). The patients in progression group had a significantly higher C-reactive protein, higher lactate dehydrogenase and lower lymphocyte count than the other groups (all p-values < 0.05). The duration of hospital stay was longer in the progression group (27.1 ± 11.4 days) compared to the other three groups (16.12 ± 5.8) (p =< 0.05). Conclusion: Nearly half of the asymptomatic cases with confirmed COVID-19 had abnormal chest CT imaging. Asymptomatic infections can have a variable clinicoradiological course. Clinically, some recover without developing symptoms, some present few mild symptoms whereas some deteriorate. Similarly, imaging follow-up may reveal resolution (partial or complete), progression or no change. Advances in knowledge: Clinicoradiological course of asymptomatic COVID-19 cases is diverse.

Background The recent outbreak of pneumonia cases in Wuhan, PR China, was caused by a novel beta coronavirus, the 2019 novel coronavirus (COVID-19). Purpose To summarize chest computed tomography (CT) manifestations of the early stage of COVID-19 infection and provide a piece of reliable imaging evidence for initial screening and diagnosis. Material and Methods From 10 January 2020 to 10 February 2020, we continuously observed chest CT imaging of 14 patients with clinically suspected new coronavirus infection in the two weeks after onset of symptoms. Ground-glass opacity (GGO), consolidation, reticular pattern, and ground-glass mimic nodules in each patient’s chest CT image were recorded. Results We enrolled 14 patients, of which nine patients had the infection confirmed by reverse transcription polymerase chain reaction (RT-PCR). Five patients were highly suspected of infection. All cases had epidemiological evidence. GGO was a dominant imaging manifestation in the initial days of infection. GGO performance accounts for 40% in 1– 2 days, 90% in 3– 6 days, and 85% in 7– 10 days. With disease progression, consolidation appeared on follow-up CT. Consolidation performance accounts for 0% in 1– 2 days, 40% in 3– 6 days, and 71% in 7– 10 days. The lesions are mostly near the pleura. The number of lesions and the extent of the lesions increased as the disease progressed. Conclusion Patients with novel coronavirus pneumonia have characteristic CT features in the initial stage of infection, which can be used as an essential supplement for nucleic acid examination.

Background: To analyze the chest computed tomography (CT) features in patients with coronavirus disease 2019 (COVID-19) pneumonia. Methods: This was a prospective descriptive study comprising 202 consecutive reverse transcriptase polymerase chain reaction (RT-PCR) positive patients who underwent CT chest. For 25 patients, follow-up CT scans were obtained. The CT images were evaluated for the number, type and distribution of the opacity, and CT severity scoring was done Results: Among the total study cohort of 202 patients, 152 were males and 50 were females .From July 07, 2020, to september07, 2020, totally 202 laboratory-confirmed patients with COVID-19 underwent chest CT. For 25 patients, follow-up CT scans were obtained. The CT images were evaluated for the number, type and distribution of the opacity, and the affected lung lobes. Furthermore, the initial CT scan and the follow-up CT scans were compared. Results were patients (98.5%) had two or more opacities in the lung and 3 (1.5%) patients has negative chest CT. 183 (90.6%) patients had only ground-glass opacities; 13 patients (6.4%) had ground-glass and consolidative opacities; and 3 patients (1.5%) had only consolidation. A total 192 of patients (96.5%) showed two or more lobes involved. The opacities tended to be both in peripheral and central 7 (3.5%) or purely peripheral distribution 192 (96.5%). 177 patients (88.9%) had the lower lobe involved.8 patients showed complete resolution of lung findings. Conclusion: In this study population, the typical CT features of COVID 19 pneumonia are ground glass opacity with or without consolidation, which is patchy and peripheral, predominantly in lower lobes.

BACKGROUND The computerised tomography (CT) characteristics of COVID-19 are reported and compared with the CT characteristics of other viruses to familiarise radiologists with potential CT trends and to determine the effectiveness of chest CT in the diagnosis and treatment of COVID-19. METHODS This was a hospital based descriptive study which involved the first 324 patients with a finding of severe acute respiratory syndrome (SARS-CoV-2) infection validated by real-time reverse transcription-polymerase chain reaction (RT – PCR). Monitoring patients (198 males, 126 females with a mean age of 46.50 years ± 8.96 [SD] and age range of 21 - 76 years) from April 2020 to July 2020. We correlated the image reports from the initial CT analysis with the findings of the laboratory studies and established possible CT patterns for viral infection. RESULTS The initial chest CT studies of the 324 SARS-CoV-2 patients showed that the disease affected all 'five lobes' in 248 (76.54 percent) patients, both 'lower lobes' in 49 (15.12 percent) patients, the right lower lobe in 23 patients (7.10 percent), and the left lower lobe and right middle lobe in 2 patients (0.62 percent). In 303 (93.52 percent) patients, the lesions were primarily peripheral and subpleural; and there were fewer lesions along the bronchovascular bundles. Two major patterns of SARS-CoV-2 lesions on CT images are GGO (ground - glass opacity) and consolidation. In 303 of the 324 patients (93.52 percent), CT showed single or multiple abnormal GGO or consolidation, or both. In the remaining 21 (6.48 percent) cases, neither GGO nor consolidation was observed on CT. Follow-up CT showed moderate or pronounced disease worsening in 12 out of 58 (20.69 percent) cases and follow-up CT showed improvement with the appearance of fibrosis and GGO resolution. CONCLUSIONS In conclusion, the use of a chest CT system in SARS-CoV-2 patients can accurately evaluate pneumonia. Most notably follow-up CT scans may help assess patients with SARS-CoV-2 pneumonia in their response to treatment. KEYWORDS SARS-CoV-2, Pneumonia, Chest Computed Tomography, Ground-Glass Opacities

Abstract Background: Chest computed tomography (CT) has been used to be a monitoring measure to assess the severity of lung abnormalities in corona virus disease 19 (COVID-19). Up to date, there has been no reports about follow-up chest CT findings from discharge patients with severe COVID-19. This study aims to describe the change pattern of radiological abnormalities from admission, to discharge, and to the last chest CT follow-up through an 83-day retrospective observation, and focuses on follow-up chest CT findings in discharged patients with severe COVID-19.Methods: Twenty-nine discharged patients (17 males, 12 females; median age, 56 years, IQR, 47-67) confirmed with severe COVID-19 from 13 January to 15 February were enrolled in this study. A total of 80 chest CT scans was performed from admission to the last follow-up. Images were mainly evaluated for ground-glass opacity, consolidation, parenchymal bands, and crazy-paving pattern. A semi-quantitative CT scoring system was used for estimating lung abnormalities of each lobe.Results: All patients received nasal cannula or/and high-flow mask oxygen therapy. Admission occurred 9 days (IQR, 5-13) after symptom onset. The median in-hospital period was 18 days (IQR, 11-26). The last follow-up chest CT was performed 66 days (IQR, 61-77) after symptom onset. Total CT scores in follow-up decreased significantly compared to that of performed in-hospital ([3, IQR, 0-5] to [13, IQR, 10-16], P < 0.001). Predominant patterns on follow-up chest CT performed 64 days after symptom onset were subpleural parenchymal bands (47%, 9/19) and complete radiological resolution (37%, 7/19). Consolidation absorbed earlier than ground-glass opacity did, and subpleural parenchymal bands were the longest-lasting feature during radiological resolution.Conclusions: Radiological abnormalities in patients of severe COVID-19 could be completely absorbed with no residual lung injury in more than two months’ follow-up. Serial chest CT scans could be used as a monitoring modality to help clinician better understand the disease course.

Abstract Background Coronavirus disease 2019 (COVID-19) is an acute viral pneumonia that had recently been found in humans. The first case was discovered in Wuhan, Hubei province, China, in December 2019. In this article, we aimed to demonstrate the clinical and radiological characteristics of COVID-19 patients in Somalia from 20 March 2020 to 20 April 2020. Results Twenty-seven patients that had a positive RT-PCR test between 20 March 2020 and 20 April 2020 were retrospectively observed. This study included 19 (70.4%) males and 8 (29.6%) females, and the mean age and range were 43 years (SD ± 14.0) and 27–70 years, respectively. The majority (59.3%) of COVID-19-infected patients had no obvious history of exposure to infected patients. The participants of our study mostly presented with dry cough 24 (88.9%) patients, fever 19 (70.4%), myalgia 18 (66.6%), and sore throat 16 (59.3%). Twenty-five of 27 patients had abnormal chest CT, while 2 (7.4%) patients had normal chest CT. The most common patterns of abnormality seen on chest CT in patients with COVID-19 were ground-glass opacity (GGO) 74.1%, crazy paving pattern 18.5%, consolidation 14.8%, and mixed GCO 11.1%. Also, the most common predominant lesion distributions were bilateral lung involvement (88.9%), peripheral distribution (77.8%), and lower lung predominance (63%). Particularly, lung cavitation, discrete pulmonary nodules, pleural effusion, and underlying pulmonary fibrosis or emphysema had not been observed. Conclusion Dry cough, fever, myalgia, and sore throat were the most clinical presentations. GGO, crazy paving pattern, patchy consolidation, and mixed GCO were the typical chest CT manifestations.
