Evaluation of MRI Sequences for Ultra-rapid Acquisition of Bile Ducts Images (BiliFast)
Gallstone, Cholangitis, Cholangiocarcinoma
About this trial
This is an interventional diagnostic trial for Gallstone focused on measuring Cholangiopancreatography by MRI, Compressed Sensing

For each patient who undergo a 1.5T MRI, 3 sequences will be done: (i) a conventional SPACE sequence, (ii) an ultra-rapid sequence (sequence CS-SPACE) acquired in apnoea and (iii) an accelerated sequence (sequence CS-SPACE) but remaining synchronized with the breath.
For each patient who undergo a 3T MRI, 3 sequences will be done: (i) a conventional SPACE sequence, (ii) an ultra-rapid sequence (sequence CS-SPACE) acquired in apnoea and (iii) an accelerated sequence (sequence CS-SPACE) but remaining synchronized with the breath.
