MR Adult Prostate WWO Protocol

Notes:
1. Always with Endorectal Coil, always with power injection
2. Patient prep: instructions given by scheduling 
3. Power injection 3mL/s, dose by weight. 20g IV.
4. Tech must be signed off on inserting Endorectal coil 
5. Send all images to PACS. Send post processed Perfusion images to COLOR PACS
6. Charge for Endorectal coil. In EPIC, to to "Charge Capture" > "Supplies" > "HB MR Imaging Coil"

Last updated: 7/22/19
Charge as: Prostate WWO, charge for Endorectal coil
Scanner preference: 3T Only. OK for MR2 for pt safety issues (notify Rad)
Coil: Torso Coil

Plane Weighting Mode Slice Gap FAT SAT FOV Notes
Survey - - - - - - Center on prostate. Ensure good signal through perineum. If pt still needs to evacuate stool allow them to do so.
AX T2 HR TSE 3mm 1mm None 240x240 Cover prostate and seminal vesicles. Ok to increase slices

Insert endorectal coil

AX T1 TSE 5mm 0.5mm None 240x300 Ok to increase slices. Cover prostate, endorectal coil and seminal vesicles
SAG T2 TSE 3mm 0mm None 180x180 Perpendicular to AX, coverage to mid humeral heads. Ok to increase slices. Cover prostate, endorectal coil and seminal vesicles
AX T2 HR TSE 3mm 0mm None 180x180 Ok to increase slices. Cover prostate, endorectal coil and seminal vesicles
COR T2 TSE 3mm 0mm None 180x180 See image for coverage. No need to cover the entire endorectal coil. Only cover prostate and seminal vesicles.
AX DWI EPI 3mm 0.3mm 180x180 Ok to increase slices. Cover prostate, endorectal coil and seminal vesicles

Contrast injection

Inject gad at the start of dynamic #6. Power injection 3 cc/sec

Plane Weighting Mode Slice Gap FAT SAT FOV Notes
AX DC 3D FFE 180 x 180 Cover prostate and seminal vesicles. OK TO INCREASE SLICES. ENSURE DYNAMICS DON’T EXCEED 80 SECONDS. SEE IMAGE FOR COVERAGE

Post process dynamics

1. On DCE study: Right click > Image Algebra > Basic T1 Perfusion 
2. Draw a ROI around the prostate 
3. “Generate” > “OK” 
4. Send all processed images to Color PACS
