Imaging findings OR Procedure details
We use a 1.5 T MRI to perform the exams.
The patient fasts 6 hours before the procedure and comes to hospital 1.30 h before the beggining of MRI.
In hospital patiend drinks 1l -1,5 l of water (depending of tolerance) mixed with 4-5 sachets of commercial Polietilenglicol solution.
What we get with this is to generate an adecuate distention of bowel that wouldn´t be possible using only water.
After the ingestion patients goes to the toilet for emptying of the bladder. A nappy is placed in the pallet of the MRI.
Coronal sequences allow a better relation between field of view included (bigger than in axial acquisition) and apneas wich will be shorter.
Axial sequences will be performed mainly from pubis including the whole pelvis.
The sequences used are:
1. Oblique Non Gated FIESTA sequence (cine sequence).
IV Buscapine vial is administrated after this to boost the slowing-down of the bowel loops avoiding moving artifacts during the rest of the procedure.
Take in account this is done after cine sequence because one of the main aims of cine sequence is to evaluate usual bowel movement in each patient.
2. Axial and Coronal FIESTA without fat supression (FS).
3. Axial and Coronal FSE T2 FS.
4. Axial and Coronal Diffusion weighted sequence (optionally only one can be performed depending of the previous features).
5. Coronal LAVA 3D FS precontrast sequence.
Another IV Buscapine vial is administrated just before the administration of Gadolinium.
6. Coronal LAVA 3D FS sequence 30,70 and 120 secs after the IV administration of Gadolinium.
