Contrast-Enhanced Ultrasound Versus Doppler Ultrasound for Detection of Early Vascular Complications of Pancreas Grafts.

The purpose of this study is to compare conventional duplex ultrasound and contrast-enhanced ultrasound (CEUS) for identifying vascular abnormalities in pancreas allografts in the immediate posttransplant setting. Identification of pancreas allografts at risk of failure may impact patient care because early intervention for vascular insufficiency can lead to graft salvage. Two radiologists who were blinded to patient outcomes performed a retrospective analysis of the postoperative Doppler ultrasound and CEUS images of 34 pancreas grafts from transplants performed between 2017 and 2019.

Genital and reproductive organ complications of Crohn disease: technical considerations as it relates to perianal disease, imaging features, and implications on management.

Objective: A relatively large proportion of patients with Crohn disease (CD) develop complications including abscess formation, stricture, and penetrating disease. A subset of patients will have genital and reproductive organ involvement of CD, resulting in significant morbidity. These special circumstances create unique management challenges that must be tailored to the activity, location, and extent of disease.

Radiology in the Study of Bone Physiology.

Rationale And Objectives: In this article, we review the core principles of bone physiology alongside imaging examples that demonstrate such principles.

Materials And Methods: The core principles of bone physiology are reviewed and further solidified with a corresponding abnormal pathophysiologic example. The key principles of bone physiology to be reviewed include the following: (1) formation and growth, (2) maintenance and repair, (3) metabolism and regulation, and (4) neoplastic disease.
