In radiology, scoring-based peer review is the dominant model focused on quality assurance, rather than quality improvement. Although designed to decrease diagnostic errors in radiology, this model has had an overall negative effect secondary to its punitive nature and lack of educational benefit. A peer learning-based system helps circumvent these issues through a multitude of ways. These include increasing learning opportunities, identifying system errors that maybe contributing to the misdiagnosis, and fostering a “just” environment where constructive feedback is given to the radiologist. By changing to the peer learning paradigm, this helps increase engagement and satisfaction by participating radiologists to improve patient care.

Fluoroscopy, CT, and MRI are key imaging modalities for evaluation of patients who have undergone advanced endoscopic interventions for treatment of achalasia, resection of early-stage gastrointestinal malignancies, weight loss procedures, and placement of lumen-apposing stents beyond the pancreas.

Consensus recommendations from the Society of Abdominal Radiology GI Bleeding Disease-Focused Panel and the American College of Gastroenterology will improve the understanding of specific examinations that are available for assessing gastrointestinal bleeding and how these should be used.

The purpose of this pictorial essay is to review different etiologies for lower extremity pain encountered on lower extremity venous sonography including acute deep venous thrombosis, chronic postthrombotic change, central venous disease, common arterial pathologies, and nonvascular abnormalities.

Contrast-enhanced US evaluations of hepatocellular carcinoma response to transarterial chemoembolization demonstrated high sensitivity in the detection of residual viable tumor yet lower specificity when compared with the current 4–6-week recommended follow-up.

Dual-energy CT allows elimination of the noncontrast acquisition at multiphase CT for overt or occult gastrointestinal bleeding, affording a reduction in radiation dose and increasing the conspicuity of contrast material extravasation through reconstructions such as iodine maps, color iodine overlays, and low–kiloelectron voltage virtual monoenergetic images.
