1. Send ADC maps and void before exam.
2. On patients that have had a previous Rectal CA MRI, use the same locations as the last exam. This will eliminate the need to call for the Body Radiologist to place lines for the angulations and coverage of the sequences.

|AX||T1||GRE||4mm||1mm||N||250mm/ Fit to Patient||Consider anterior sat band if lots of abdominal wall motion.|
|SAG||T2||FSE||4mm||1mm||N||Fovea to Fovea||Freq A-P. Add anterior sat band to reduce abdominal wall motion. Used to plan oblique planes.|
|COR||T2||FSE||4mm||1mm||N||Fovea to Fovea.||Symphysis pubis through sacrum.|
|AX||T2||FSE||4mm||1mm||N||200mm/ Fit to Patient||Consider anterior Sat Band to reduce artifact from anterior abdominal wall. Cover aortic bifurcation through perineum.|
|AX Oblique||T2||FSE||3mm||0mm||N||Fovea to Fovea||Add anterior sat band to reduce abdominal wall motion. Performed perpendicular to the tumor. Use same angles and coverage if patient has a prior Rectal MRI exam at OHSU. Otherwise, call MR radiologist for planning.|
|COR Oblique||T2||FSE||3mm||0mm||N||Fovea to Fovea||Performed parallel to the anal canal. May plan without radiologist.|
|3D T2 AXIAL||T2||3D T2||N||Fovea to Fovea||L5-S1 through perineum.|
|AX Oblique||T1||3D THRIVE Pre- BH||Y||Fovea to fovea||Add anterior sat band to reduce abdominal wall motion. Same plane as the AX Oblique T2|
Power inject 2mL/sec. Gad dosed by weight. Trigger when contrast reaches iliacs.
|AX Oblique||T1||3D THRIVE 3-phase Dynamics||Y||Fovea to fovea||Add anterior sat band to reduce abdominal wall motion. Same plane as the AX Oblique T2|
|AX Oblique||T1||HI-RES THRIVE post- con||4mm||0mm||Y||Fovea to fovea||Add anterior sat band to reduce abdominal wall motion. Same plane as the AX Oblique T2|
|SAG||T1||3D thrive post- con||Y||Fovea to fovea|
|AX Oblique||T2||DWI||4mm||0mm||SPIR||Match AX OBLIQUE TSE T2||Add anterior sat band to reduce abdominal wall motion. Same plane as the Ax Oblique T2. Trigger & track. Free-breathing sequence, so please position slices accordingly. B=0, 1000. NEX 6|
|ADC MAP FROM DWI||Please do ADC maps on all MRI Rectal pts scans and send them to pacs|
