Objective: The purpose of this study was to compare a 3D T2-weighted imaging sequence with a conventional multiplanar 2D turbo spin-echo T2-weighted sequence in terms of tumor detection and staging of prostate cancer, as well as image quality.
Materials And Methods: Before prostatectomy, 38 men (mean age, 60 years) with prostate cancer underwent MRI of the prostate with multiplanar 2D turbo spin-echo T2-weighted sequences (total acquisition time, approximately 11 minutes 4 seconds) and a 3D T2-weighted sampling perfection with application optimized contrasts sequence with different flip angle evolutions (SPACE) (acquisition time, approximately 3 minutes 52 seconds). Two blinded observers in consensus reviewed 2D turbo spin-echo T2-weighted images and SPACE images for detection of peripheral zone cancer, extracapsular extension, and seminal vesicle invasion.
The pelvic cake kidney in which there is complete fusion of both kidneys into a single renal parenchymal mass has been described as the rarest of renal fusion anomalies. Pelvic cake kidney most commonly drains via 2 separate ureters, with fewer than 10 reports demonstrating a cake kidney drained by a single ureter. We present the first ever reported case of a pelvic cake kidney drained by a single ureter in association with a unicornuate uterus.
View Article and Find Full Text PDFOvarian stromal hyperplasia and ovarian hyperthecosis are non-neoplastic conditions of the ovary associated with clinical manifestations of hyperandrogenism from ovarian production of male hormones. In this article, we present the first published cases of the magnetic resonance imaging appearance of these conditions, which may mimic that of ovarian neoplasm. In contrast to bilateral ovarian vein sampling, magnetic resonance imaging may provide a noninvasive means of suggesting a diagnosis of ovarian stromal hyperplasia/ovarian hyperthecosis when a hormone-secreting ovarian neoplasm is suspected clinically and thereby may assist in identifying patients who may be effectively treated nonsurgically with gonadotrophin-releasing hormone therapy.

For depiction of pulmonary arterial anatomy and morphology, MRA techniques are compared with CT angiography and digital subtraction x-ray angiography. Perfusion, flow, and function are emphasized, as the integrated MR examination offers a comprehensive assessment of vascular morphology and function.

The questionnaires were detailed inquiries into licit and illicit drug use by the students and their parents. The two areas this study concentrated on were frequency of drug use and the relationship between student and parent drug use.
