To reduce RF-induced heating, standard passive RF traps are known to be efficient. Novel miniaturized RF traps are as efficient as standard ones for this purpose. Furthermore, it is demonstrated that RF traps enable a restoration of the signal intensity pattern of the coil. It is thus possible to perform a MR endoscopy of deeper regions of the bowel (after left colonic flexure for instance) since the coaxial cable incorporating miniaturized RF traps now may be inserted through the rectum with limited discomfort for the patient.
