MR4 AND MR2
Pt is feet first
Torso coil
Use correct endorectal coil for 3T or 1.5T / MR3
Pt is head first
Cardiac coil
Use correct endorectal coil for 3T
To start exam: Pull over “PROSTATE w/ER COIL PART 1” and scan. Pull the patient out, insert the tip, plug in the coil, and then pull over “PART 2” sequences. Do not set up your sequences for part 2 before plugging in the ER coil.
Coil: Torso Coil
MODE: / SLICE / GAP / FAT SAT / FOV / SCAN RANGE / Notes
Survey / CENTER ON PELVIS/PROSTATE / Ensure good signal through perineum.
If pt still needs to evacuate stool allow them to do so.
AX / T2 HR / TSE / 3mm / 1mm / N / 240x240 / Cover prostate and seminal vesicles / Ok to increase slices
Insert endorectal coil
VIP: on MR3, you must first only pull over the first scout and AX T2.
Do not pull over the other sequences until after you insert the endorectal coil.
Survey / Ensure good signal through prostate
AX / T1 / TSE / 5mm / 0.5mm / N / 240x300 / Cover prostate, endorectal coil and seminal vesicles / Ok to increase slices.
SAG / T2 / TSE / 3MM / 0MM / N / 180x180 / Cover prostate, endorectal coil and seminal vesicles / Perpendicular to AX, coverage to mid humeral heads. Ok to increase slices.
AX / T2 HR / TSE / 3MM / 0MM / N / 180x180 / Cover prostate and seminal vesicles / Ok to increase slices.
3D T2 AX / T2 / -- / -- / N / Fovea to Fovea / L5/S1 through perineum / Please perform 3D T2.
COR / T2 / TSE / 3MM / 0MM / N / 180x180 / Cover prostate and seminal vesicles / See image for coverage. No need to cover the entire endorectal coil. Only cover prostate and seminal vesicles.
AX / DWI / EPI / 3MM / 0.3MM / N / 180x180 / Cover prostate, endorectal coil and seminal vesicles / Ok to increase slices.
Inject gad at the start of dynamic #6. Power injection 3cc/sec
AX / DCE / 3D FFE / - / - / N / 180x180 / Cover prostate and seminal vesicles / OK TO INCREASE SLICES. ENSURE DYNAMICS DON’T EXCEED 80 SECONDS. SEE IMAGE FOR COVERAGE.
