1. CT v. MRI Part 2 Body Imaging

2. Pelvis ▪MR and CT both have roles in pelvic imaging ▪CT allows for bony info and some smaller structures ▪MR is very good for uterine anatomy and has no ionizing radiation

3. Endometriosis ▪MR allows for visualization of all the layers of the uterus.

4. Bladder cancer ▪Both MR and CT can be used

6. Prostate cancer ▪Endo coils have increased the utility of MR in prostate imaging ▪CT is useful in staging bony involvement

7. Colon mets ▪Frequently seen as liver mets; however, intestinal lesions can met locally

8. Liver ▪CT is very good for most abnormalities ▸ Spiral has improved the efficacy of CT ▪MR has application, especially in mets ▸ Iron chelate contrast media

9. Hemangioma ▪Questionable low density areas can be evaluated with spiral techniques and power injectors; thereby, increasing the overall diagnostic ability of the exam

12. Liver mets ▪For accurate diagnosis contrast is a must ▪Some lesions are difficult to adequately visualize ▪MR has serious application in liver mets

17. Lungs ▪As a rule the chest is the purview of CT ▪MR as some use in the mediastineum and chest wall

21. Abdomen ▪Both CT and MR work in the abdomen ▪The key is the appropriate modality for the diagnosis

22. Pancreatitis

23. Herniations ▪Omacele

24. Kidney ▪Renal artery ▪Renal tumors

27. Neuroblastoma ▪Wilm’s tumor

28. Appendicitis ▪Big increase in use since the middle 90s.

30. Adrenal ▪MR is great for adrenal abnormalities because of it’s multiplanar capabilities ▪Can use surface coils to increase image quality

34. Flow Without contrast ▪A variety of fluids move within the abdomen and MR techniques have been developed or are being developed for all of them

37. Organ Lacerations ▪Most of the structures are at risk for traumatic laceration resulting in a multitude of outcomes
