To evaluate the diagnostic accuracy of split-bolus single-scan computed tomography angiography (CTA) protocol for evaluation of acute mesenteric ischemia and alternate diagnoses. ⋯ • Split-bolus CTA protocol for mesenteric ischemia has great diagnostic accuracy with lower radiation exposure and fewer images to interpret compared with standard multiphasic CTA.
-
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.

Comparative Study
Comparison of interlaminar CT-guided epidural platelet-rich plasma versus steroid injection in patients with lumbar radicular pain.
The treatment of persistent lumbar radicular pain (LRP) by CT-guided epidural steroid injection (ESI) is extensively used and associated with rare but serious complications. Platelet-rich plasma (PRP), which has recently been shown to favor healing and the anti-inflammatory process by delivering growth factors and cytokines, might be an alternative and potentially safer option. We compared the efficacy of interlaminar CT-guided epidural PRP injections (EPRPI) and ESI in the treatment of persistent LRP (> 6 weeks). ⋯ • Treatment of persistent lumbar radicular pain by CT-guided epidural steroid injections is associated with rare but serious complications. • By promoting an anti-inflammatory process, epidural platelet-rich plasma injections might be an alternative treatment of persistent radicular pain. • Platelet-rich plasma CT-guided epidural injections are similar to steroid for the treatment of lumbar radicular pain at 6 weeks post-procedure and could be a safer option.

The diagnostic reading of follow-up low-dose whole-body computed tomography (WBCT) examinations in patients with multiple myeloma (MM) is a demanding process. This study aimed to evaluate the diagnostic accuracy and benefit of a novel software program providing rapid-subtraction maps for bone lesion change detection. ⋯ • A novel algorithm has been successfully applied to generate motion-corrected bone subtraction maps of whole-body low-dose CT scans in less than 2 min. • Motion-corrected bone subtraction maps significantly facilitate the reading of follow-up whole-body low-dose CT scans in multiple myeloma by reducing reading time and increasing sensitivity.

• 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.
