WebMar 15, 2024 · An MRI with contrast is an imaging test that combines magnetic and radio wave imaging with an injection of a contrast agent (dye). The dye highlights blood vessels, organs, and specific soft tissues so they show up more clearly and help your radiologist determine a diagnosis. WebLong course: ~50 Gy in 2528 fractions daily over 5-6 weeks + radiosensitizing chemotherapy (5-FU or capecitabine) Short course: 25 Gy in 5 fractions over 1 week (without chemotherapy) While highest radiation dose is aimed at the rectum, other organs also receive high doses of radiation, such as the bladder, sacrum, pre-sacral fat, and prostate.
