[Carcinoid tumor of the small bowel: value of hydro-MR imaging for diagnosis]

Hydro-MR imaging is a technique based on the use of a strongly T2-weighted single-shot fast spin-echo (SSFSE) sequence, similar to that used for MR-cholangiography. We report herein one case of carcinoid tumor of the small bowel diagnosed by hydro-MR imaging. This non invasive MR technique showed suggestive features such as radial convergence and segmental dilatation of a small bowel loop, similar to those seen on conventional follow-through studies. This case illustrates the major role that may be played in the future by hydro-MR imaging for the non invasive diagnosis of carcinoid tumor of the small bowel without the use of ionizing radiation.
