Objective The purpose of this study was to investigate the value of cone beam computed tomography (CBCT) scanners versus plain radiography for detection and classification of fractures of the wrist and hand after acute trauma. Methods Images of 56 patients that received both plain radiography and CBCT after presenting to our emergency department with suspected fracture of the wrist or hand between November 2015 and July 2016 were analyzed retrospectively by three blinded observers. Results Using plain radiographs compared to CBCT, 69% of fractures of the carpals and 37% of fractures of metacarpals and phalanges remained undetected. Higher fracture classification reliability in radius fractures was observed when using CBCT. Conclusion CBCT is superior to plain radiography in detecting wrist and hand fractures in an emergency setting and presents an alternative first line imaging tool in the acute trauma patient population.

Background The latest International Myeloma Working Group (IMWG) guideline recommends low-dose whole-body (WB) computed tomography (CT) as the first-line imaging technique for the initial diagnosis of plasma cell disorders. Purpose To evaluate diagnostic performances of CT and diffusion-weighted imaging (DWI) as the first-line imaging modalities and assess misclassification rates obtained following the guideline. Material and Methods Two independent radiologists analyzed CT (acquired as PET/CT) and DWI (3-T; b-values = 50 and 900 s/mm2) of patients newly diagnosed with plasma cell disorder, categorizing the number of bone lesions. Diagnostic performance of CT and DWI was compared using the McNemar test, and misclassification rates were calculated with a consensus WB-MRI reading as the reference standard. Differences in lesion number categories were assessed using marginal homogeneity and kappa statistics. Results Of 56 patients (36 men; mean age = 63.5 years), 39 had myeloma lesions. DWI showed slightly higher sensitivity for detecting myeloma lesions (97.4%) than CT (84.6%–92.3%; P > 0.05). CT showed significantly higher specificity (88.2%) than DWI (52.9%–58.8%; P<0.05). CT had a higher additional study requirement rate than DWI (7.7%–15.4% vs. 2.6%), but a lower unnecessary treatment rate (11.8% vs. 41.2%–47.1%). Both readers showed significant differences in categorization of the number of lesions on CT compared with the reference standard ( P < 0.001), and one reader showed a significant difference on DWI ( P = 0.006 and 0.098). Conclusion CT interpreted according to the IMWG guideline is a diagnostically effective first-line modality with relatively high sensitivity and specificity. DWI alone may not be an acceptable first-line imaging modality because of low specificity.

AbstractThe motor function of the thumb and its alignment with regard to the hand make it particularly vulnerable to trauma. Pathology encountered in this joint is varied, and imaging techniques play a crucial role in the diagnosis and characterization of injury. Despite advances in imaging technology, acute thumb injuries remain a challenge for radiologists. Currently, standard radiography and ultrasonography are frequently used first-line imaging techniques. Computed tomography is most often indicated for complex fractures and dislocations. Magnetic resonance imaging may be used to optimally characterize soft tissues and bone marrow. In this article, we cover the most common traumatic injuries: fractures, dislocations, collateral ligament injuries of the metacarpophalangeal joint, as well as soft tissue lesions.

Urological Emergencies

High resolution ultrasound with color Doppler is the first-line imaging investigation in the evaluation of acute scrotum. It plays a crucial role in distinguishing urological emergencies necessitating immediate surgical exploration from those that can be managed conservatively. Acute scrotal pathologies can involve the scrotal sac or its contents like testis, epididymis and testicular appendages and could range from benign, self-limiting conditions to emergencies. In this pictorial essay, we briefly review the ultrasonographic technique, scrotal anatomy and characteristic imaging features of various pathologies presented as acute scrotum.

We present the case of splenogonadal fusion in a 53-year-old male patient assessed by ultrasound and MRI, confirmed by pathologic examination. In addition to B-mode and colour-coded Doppler ultrasound, shear wave elastography and CEUS were performed and are presented in detail. Splenogonadal fusion is a rare congenital anomaly presumably caused by an abnormal attachment of splenic tissue to the gonad during gestation. Diagnosis is challenging for clinicians and in unclear cases splenogonadal fusion might cause unnecessary orchiectomies with benign pathologic results. Ultrasound is the first-line imaging modality in the diagnosis of testicular pathologies. This case report summarizes all available modern ultrasound imagingtechnologies and highlights the possibilities for the diagnosis of splenogonadal fusion.
