• Novel coronavirus (COVID-19)-infected pneumonia usually manifests as bilateral ground-glass opacities in the lung periphery on chest CT scans. • Role of radiologists includes not only early detection of lung abnormality, but also suggestion of disease severity, potential progression to acute respiratory distress syndrome, and possible bacterial co-infection in hospitalized patients.

To evaluate the implications of hepatic subcapsular and capsular flows using ultrasonography (US) in children after Kasai operation. ⋯ • Hepatic subcapsular or capsular flows can be useful not only for the diagnosis but also for the postoperative follow-up in patients with biliary atresia. • Increased liver stiffness and splenomegaly after the Kasai operation were associated with presence of subcapsular or capsular flow on ultrasonography. • Evaluation of hepatic subcapsular and capsular flows could be needed to assess disease progression after receiving the Kasai operation.

We used the status of microvascular invasion (MVI) at primary resection to help treatment selection for hepatitis B virus-positive (HBV+) recurrent hepatocellular carcinoma (rHCC) patients in Barcelona Clinic Liver Cancer (BCLC) stage B-C. ⋯ • This study aimed at the determination of the optimal treatment options (ablation /resection vs TACE) in case of recurrent HBV-related HCC. • It showed that MVI status, established at primary resection of HCC, was a powerful marker for selecting the best treatment option in these patients. • In MVI(-) patients, RR/RFA achieved a better survival than TACE. In MVI(+) patients, TACE shared similar survival.

To evaluate the agreement among readers with different expertise in detecting suspicious lesions at prostate multiparametric MRI using Prostate Imaging Reporting and Data System (PI-RADS) version 2.1. ⋯ • Agreement on index lesion detection among radiologists of various experiences is substantial to excellent using PI-RADS v2.1. • Concordance between experienced readers is higher than between less-experienced readers. • Concordance on absence of lesions is excellent across readers' experience.

The purpose of this study was to observe the imaging characteristics of the novel coronavirus pneumonia. ⋯ • High-resolution CT (HRCT) of the chest is critical for early detection, evaluation of disease severity and follow-up of patients with the novel coronavirus pneumonia. • The manifestations of the novel coronavirus pneumonia are diverse and change rapidly. • Radiologists should be aware of the various features of the disease and temporal changes.
