1. CT routine/oncology abdomen and pelvis: for cancer originating in the abdomen, melanoma, lymphoma or infectious/inflammatory processes such as crohn's disease or diverticulitis

2. CT routine/oncology abdomen: for cancer originating above the diaphragm such as lung, breast or brain. If the patient has proven mets in the pelvis but has breast cancer, it is okay to also scan pelvis. Also for infectious/inflamm processes involving exclusively the upper abdomen, like cholecystitis.

3. Dual phase liver: Used only for cirrhosis to evaluate for HCC. scans the liver in the arterial and portal venous phases of iv contrast

4. Renal or Adrenal mass protocol: Used to characterize newly found renal or adrenal masses by scanning in the unenhanced, portal venous phase, and delayed phase. The enhancement and washout determines if it's cancer. Not used for proven RCC or adrenal cancer, but can be used to re-evaluate indeterminate lesions.

5. Stone study: used for renal stones - frequently ordered by ER. is a CT of abd and pelvis with no contrast

6. Triple phase liver: used for neuroendocrine cancer (usually carcinoid) and usually ordered by manisha shah, who is the NEC expert. should also add pelvis because Dr. shah asks for it

7. Hematuria: used it patient has painless hematuria. is a stone study followed by iv contrast and delayed phase, which is helpful to evaluate the ureterus and bladder - similar to IVP

8. If patient has Cr above 1.5 or if service requests no contrast, then protocol with no iv contrast

9. CT Pancreas and Onc Pancreas: self explanatory
