With advances… (More)
The purpose of this pictorial essay is to demonstrate the imaging features (ultrasound, mammogram, and magnetic resonance imaging (MRI)) of AlloDerm(®)(LifeCell Corp.; Branchburg, NJ), an acellular dermal matrix sometimes used in both primary and reconstructive breast surgeries. AlloDerm(®) is derived from cadaveric dermis and provides an immunologically… (More)
A 65-year-old female with biopsy-confirmed nephrogenic systemic fibrosis (NSF) received a kidney transplantation. Despite good kidney function, her symptoms continued to progress. Deferoxamine was administered intramuscularly at 500 mg/day and later 1000 mg/day after 1 week with no adverse effects. Urine excretion of gadolinium increased from 6.0 μg/day to… (More)
Epithelioid hemangioendothelioma is a rare vascular malignancy often characterized by a clinically indolent course and delayed diagnosis. The authors present the radiologic and pathologic features of a case of pulmonary epithelioid hemangioendothelioma which was initially thought to be calcified granulomas.
This pictorial essay briefly discusses methods for optimizing bowel imaging with magnetic resonance imaging (MRI) and illustrates the MRI appearance of a variety of unusual lesions involving or related specifically to the large bowel.
Semi-public displays are systems designed to strengthen awareness and collaboration among small co-located group environments.
