The purpose of this study was to investigate the diagnostic value of color Doppler ultrasound combined with superb microvascular imaging (SMI) in the detection of small renal tumors less than 3 cm treated with Jinkui Shenqi pills. 50 cases were randomly selected from the patients with angioleiomyoma (a kind of small renal tumor) less than 3 cm confirmed by pathological examination and treated in our hospital from January 2018 to January 2020. All patients were treated with Jinkui Shenqi pills. All patients were first detected by color Doppler ultrasound and then by SMI. The results of color Doppler ultrasound were used as the control group, while those of color Doppler ultrasound combined with SMI were used as the experimental group. After that, the specificity, sensitivity, positive and negative detection results, and detection accuracy were compared between the two groups. The specificity and sensitivity in the experimental group were significantly higher than those in the control group, with statistical significance ( P < 0.05 ). The cases of positive and negative detection results in the experimental group were significantly higher than those in the control group, with statistical significance ( P < 0.05 ). The detection accuracy in the experimental group was significantly higher than that in the control group, with statistical significance ( P < 0.05 ). The specificity, sensitivity, positive and negative detection results, and detection accuracy of color Doppler ultrasound combined with SMI in the detection of small renal tumors less than 3 cm treated with Jinkui Shenqi pills were all significantly higher than those of color Doppler ultrasound; therefore, the application of color Doppler ultrasound combined with SMI for the diagnosis of small renal tumors is of high value.

The neural network algorithm of deep learning was applied to optimize and improve color Doppler ultrasound images, which was used for the research on elderly patients with chronic heart failure (CHF) complicated with sarcopenia, so as to analyze the effect of the deep-learning-based color Doppler ultrasound image on the diagnosis of CHF. 259 patients were selected randomly in this study, who were admitted to hospital from October 2017 to March 2020 and were diagnosed with sarcopenia. Then, all of them underwent cardiac ultrasound examination and were divided into two groups according to whether deep learning technology was used for image processing or not. A group of routine unprocessed images was set as the control group, and the images processed by deep learning were set as the experimental group. The results of color Doppler images before and after processing were analyzed and compared; that is, the processed images of the experimental group were clearer and had higher resolution than the unprocessed images of the control group, with the peak signal-to-noise ratio (PSNR) = 20 and structural similarity index measure (SSIM) = 0.09; the similarity between the final diagnosis results and the examination results of the experimental group (93.5%) was higher than that of the control group (87.0%), and the comparison was statistically significant ( P < 0.05 ); among all the patients diagnosed with sarcopenia, 88.9% were also eventually diagnosed with CHF and only a small part of them were diagnosed with other diseases, with statistical significance ( P < 0.05 ). In conclusion, deep learning technology had certain application value in processing color Doppler ultrasound images. Although there was no obvious difference between the color Doppler ultrasound images before and after processing, they could all make a better diagnosis. Moreover, the research results showed the correlation between CHF and sarcopenia.

Objective.To evaluate the diagnostic value of color Doppler ultrasound (CDUS) for the detection of sacroiliitis, in patients with inflammatory back pain (IBP).Methods.Consecutive patients with IBP and suspected axial spondyloarthritis (SpA), but without a definitive diagnosis, were included. Consecutive patients with defined SpA and axial involvement were included as a control group. All patients underwent clinical evaluation, magnetic resonance imaging (MRI), and CDUS of sacroiliac joints (SIJ) within the same week. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for the diagnosis of sacroiliitis by CDUS were calculated, using MRI as the gold standard.Results.There were 198 SIJ evaluated in 99 patients (36 with previous SpA). There were 61 men (61.6%), with a mean age of 39.8 years (SD 11.3) and median disease duration of 24 months (IQR 12–84). At the patient level, CDUS had a sensitivity of 63% (95% CI 48.7–75.7%) and a specificity of 89% (95% CI 76–96%). The PPV was 87.2% (95% CI 72.6–95.7%) and the NPV was 66.7% (95% CI 53.3–78.3%). At joint level, CDUS had a sensitivity of 60% (95% CI 49–70%) and a specificity of 93% (95% CI 88–98%). The PPV was 83% (95% CI 78–95%) and the NPV was 43% (95% CI 33–56%). The sensitivity of CDUS for the diagnosis of axial SpA was 54% (95% CI 36.6–71.2%), specificity was 82% (95% CI 63.1–93.9%), PPV was 79% (95% CI 57.8–92.9%), and NPV was 59% (95% CI 42.1–74.4%).Conclusion.CDUS showed adequate diagnostic properties for detection of sacroiliitis and is a useful tool in patients with IBP.

Objective: To investigate the diagnostic value of color Doppler ultrasonography applied to infertile patients with chronic salpingitis and mycoplasma infection. Methods: 116 infertile patients with chronic salpingitis and mycoplasma infection were selected in this investigation. After these patients were admitted to hospital, they all underwent color Doppler ultrasound guided hysterosalpingogram and X-ray hysterosalpingography, in order to make definitive diagnoses, and the X-ray hysterosalpingography was considered as the gold standard. The diagnostic value and rates of adverse reaction between color Doppler ultrasound guided hysterosalpingogram and X-ray hysterosalpingography were evaluated. Results: A total of 116 patients with chronic salpingitis and mycoplasma infection received color Doppler ultrasound guided hysterosalpingogram and X-ray hysterosalpingography. Diagnostic coincidence rates were equal, and no statistical difference could be observed (P > 0.05), with respect to the tubal patency in double sides, tubal obstruction in double sides, tubal patency in single side, and tubal obstruction in single side. When concerning adverse reactions, the incidence rates of allergy and colporrhagia between two groups were statistically significantly different (P = 0.025 and P = 0.040, respectively). In addition, the total incidence rate of adverse reactions was also statistically significant different (P = 0.003). Conclusion: The color Doppler ultrasound aided hysterosalpingogram could make a diagnosis intuitively and clearly for patients with chronic salpingitis and mycoplasma infection, and can be used as the preferred method for diagnosing tubal infertility.

Background: The efficacy of color Doppler ultrasound, multislice spiral CT combined with serum alpha-fetoprotein (AFP) and alpha-fetoprotein heterogeneity (AFP-L3) in the diagnosis of primary hepatic carcinoma was evaluated. Methods: Seventy-nine patients with primary hepatic carcinoma (PHC group) and 50 patients with benign liver lesions (benign control group) admitted in Yantaishan Hospital (Yantai, China) from January 2016 to December 2018 were selected. The liver was scanned by color Doppler ultrasound and multiple multislice spiral CT. The serum AFP and AFP-L3 levels were detected by electrochemiluminescence. The value of color Doppler ultrasound, multislice spiral CT combined with serum AFP and AFP-L3 in diagnosis of primary liver cancer was retrospectively analyzed. Results: The color Doppler flow imaging (CDFI) showed a high-speed and high-resistance spectrum. The serum AFP and AFP-L3 levels of patients with primary hepatic carcinoma were significantly higher than those of the benign control group were (U=138.000 and 155.500, P=0.000 and 0.000), P<0.01. The sensitivity, accuracy and negative predictive value of color Doppler ultrasound, multislice spiral CT combined with serum AFP and AFP-L3 examinations for diagnosis of primary hepatic carcinoma were 96.20, 90.70 and 93.18%, which was significantly improved compared with each single examination (X2=27.888, 17.511 and 16.202, P=0.000, 0.002 and 0.003), P<0.01. Conclusion: Color Doppler ultrasound, multislice spiral CT combined with AFP and AFP-L3 examination could significantly improve the diagnosis efficiency of primary hepatic carcinoma, which was beneficial to early clinical diagnosis and early treatment.
