The theme of this year's conference was sustainability, with a focus on(More)
Sonication is a simple method for reducing the size of liposomes. We report the size distributions of liposomes as a function of sonication time using three different techniques. Liposomes, mildly sonicated for just 30 sec, had bimodal distributions when surface-weighted with modes at about 140 and 750 nm. With extended sonication, the size distribution(More)
RATIONALE AND OBJECTIVES To measure perceptions of radiology residents regarding the imaging needs of the developing world and the potential role of an organized global health imaging curriculum during residency training.

We present a case of bilateral retropharyngeal parathyroid hyperplasia detected with 4D-CT in a patient with persistent primary hyperparathyroidism and failed neck exploration. We discuss the embryologic basis of ectopic retropharyngeal parathyroid adenomas and hyperplasia and the utility of 4D-CT in their localization for surgical planning.
A 38-year-old man with melanoma of the right flank underwent a staging 18F-fluoro-2-deoxyglucose (FDG) PET/CT scan, which demonstrated a hypermetabolic extrarenal mass in the left retroperitoneal space, concerning for metastatic melanoma. However, surgical pathology demonstrated an angiomyolipoma (AML). Although AMLs can rarely occur in an extrarenal(More)
