Time-resolved MR angiography of renal artery stenosis in a swine model at 3 Tesla using gadobutrol with digital subtraction angiography correlation.

Purpose: To establish the minimum dose required for detection of renal artery stenosis using high temporal resolution, contrast enhanced MR angiography (MRA) in a porcine model.

Materials And Methods: Surgically created renal artery stenoses were imaged with 3 Tesla MR and digital subtraction angiography (DSA) in 12 swine in this IACUC approved protocol. Gadobutrol was injected intravenously at doses of 0.

Breast conserving therapy with accelerated partial breast versus external beam whole breast irradiation: comparison of imaging sequela and complications in a matched population.

Our purpose was to evaluate and compare the imaging sequela and complications of accelerated partial breast irradiation (APBI) with those occurring in patients treated with standard external beam therapy. Patient selection included those who met the criteria for possible ABPI: age 45 or older; cancer stage T1N0M0 or ductal carcinoma in situ 3 cm or less, and negative surgical margins. One hundred and ninety seven had complete records and films available for review.

Atypical abdominal hernias in the emergency department: acute and non-acute.

The objective of this pictorial essay is to review uncommon abdominal hernias, many of which present to the Emergency Department with abdominal pain. These hernias may be congenital, post-traumatic, or iatrogenic in origin. They may present as an acute (surgical) abdomen without localizing signs or symptoms.
