Quality of Image and Performance Diagnoses of the 3D Sequence of Cholangio-pancreatography MRI in Apnea With Compressed Acquisition

The sequence of 3D CP-IRM, used in current practice in the protocols of bilio-pancreatic imaging, can be thus optimized to reduce acquisition time, thus the artefacts of movement, in particular in 3T. It remains however to estimate if the quality of obtained image is equivalent at least to that of the conventional sequence, without apnea, 3D CP-IRM.

To summarize, the investigators suggest comparing the classic sequence (Fast Relaxation Fast Spin Echo (FRFSE) 3D) already existing with the same sequence to which will be added a technique of CS allowing its acquisition at shortened time(weather), with respiratory trigger on one hand and in apnea on the other hand. For the patient, this study will have for consequence only the addition of 2 sequence MRI, one of the 2 minutes 30 seconds (with respiratory trigger) and other one of the 20 seconds (in apnea).
