[MRI of the post-traumatic penis].

Penile trauma, though rare, requires specialized management. Fibrotic sequelae from lesions of the tunica albuginea and corpora cavernosa must be prevented given their impact of the erectile function. Knowledge of penile anatomy enables acquisition and interpretation of penile MRI, preferably performed in the first few hours following injury.

[MRI in static and dynamic disfunction of the female floor].

MRI is taking a growing place for pelvic prolapse diagnosis. A strict technical protocol with static and dynamic sequences is required with rectal and vaginal ultrasound gel. A good knowledge of physiology and anatomy of pelvic and perineal muscles is mandatory as well as a clinical approach of various pathologic prolapses.

Interstitial pregnancy: role of MRI.

We report the MRI features of two cases of interstitial pregnancy. In both cases, MRI was able to localize the ectopic pregnancy by showing a gestational structure surrounded by a thick wall in the upper part of the uterine wall separated from the endometrium by an uninterrupted junctional zone. Because US may confuse angular and interstitial pregnancies and because interstitial pregnancy has a particular evolutive course, MR imaging may play a key role in the diagnosis and management of women with interstitial pregnancy.
