Effort-induced thrombosis: diagnosis with three-dimensional MR venography

A case of Paget-von Schrötter syndrome diagnosed with gadolinium-enhanced magnetic resonance (MR) venography is described. MR enabled a comprehensive evaluation with identification of the thrombus within the left subclavian vein and a hypertrophied anterior scalene muscle as the probable cause of the patient's condition. We describe the MR venography technique used for evaluation of the subclavian vein and the imaging findings in this entity.

Magnetic resonance angiography in prostatodynia.

Three-dimensional magnetic resonance venography (3D MRV) of the prostate and the pelvic cavity was demonstrated in 8 normal subjects and 12 patients with prostatodynia. In all normal subjects and patients, 3D MRV images were successfully obtained. The deep dorsal vein of the penis sends major branches into the anterior and lateral capsular veins as well as into the internal pudendal vein. In patients with prostatodynia, the anterior and lateral capsular veins were much thicker in diameter than those in normal subjects, suggesting venous congestion. This congestion was also remarkable in the venous plexuses behind the bladder or along the lateral side of the pelvis in patients with prostatodynia. Another characteristic sign of the disease was a narrowing or an interruption of the internal pudendal vein. Prostatodynia is postulated to be caused by intrapelvic venous congestion.
