Brief Summary

The Institute of Imaged-Guided Surgery (IHU Strasbourg) has two clinical Magnetic Resonance Imaging (MRI) scanners, one with a 3T (3 Teslas) magnetic field used for diagnosis, the other with a magnetic field of 1,5T (1,5 Teslas) used for the interventional (Pre / per / postoperative). The reference for the visualization of the biliary and pancreatic ducts is a relatively long sequence that needs a breathing-synchronized acquisition leading to artefacts on the images (blur effect). In order to reduce and/or standardize the acquisition time as well as to limit artefacts, accelerated sequences are developed. Such sequence is available in France recently in the form of WIP Siemens (Work In Progress: sequence in test phase at manufacturer to be marketed in the short or medium term on clinical machines). It incorporates a Compressed Sensing (CS) acquisition scheme allowing the acquisition of a 3D (3 dimensions) sequence similar to the usual sequence by drastically reducing the acquisition time, the sequence CS-SPACE. This sequence exists in two forms:

  • An ultra-rapid sequence acquired in apnea
  • An accelerated sequence but remaining synchronized with the breath. The study carried out here on a large number of patients, with two different magnetic fields, applied routinely for diagnosis or anticipation of surgery, could be used by the community of radiologists, hepatogastroenterologists and also digestive surgeons Hepatobiliary.

Outcome Measures

Primary Outcomes (1)

  • Global quality of the images evaluated with a Likert score

    The global Likert score corresponds to the average of scores varying between 1 and 5 and based on the following criteria : i. diagnostic quality (feasibility of establishing a diagnosis when reading the image), including canal visibility (from score 1 = no diagnostic to score 5 = Excellent) ii. the sharpness of the image, especially the canal sharpness (from score 1 = too blurry / illegible to score 5 = sharp) iii. removal of the background signal (contrast quality) (from score 1 = too much background / illegible to score 5 = no background). The global Likert score will vary between 1 (worst) and 5 (best) as well.

    1 day: from the consent signature to the end of the exam

Secondary Outcomes (4)

  • Comparison of the global quality of the images evaluated with a Likert score between the three sequences performed with the 1.5T MRI scanner

    1 day: from the consent signature to the end of the exam

  • Comparison of the global quality of the images evaluated with a Likert score between the three sequences performed with the 3T MRI scanner

    1 day: from the consent signature to the end of the exam

  • Comparison of the sequences between 1.5T and 3T MRI scanners evaluated with the Likert score

    1 day: from the consent signature to the end of the exam

  • Performance of each sequence in the visualization of the pathology and / or an anatomical variant in the 1.5T magnetic field group, evaluated in percentage

    1 day: from the consent signature to the end of the exam

Study Arms (2)

1.5T magnetic field

OTHER

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.

Other: ultra-rapid acquisition of bile ducts images

3T magnetic field

OTHER

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.

Other: ultra-rapid acquisition of bile ducts images

Interventions

On top of the conventional SPACE sequence, 2 supplementary sequences will be performed with the ultra-rapid sequence (sequence CS-SPACE) either acquired in apnoea or synchronized with the breath.
