Pilot Study to Develop 3 Tesla MRI for Evaluation of Renal Tumors

Study Overview
=================
Brief Summary
-----------------
The goal of this clinical research study is to find out if 3 Tesla MRI is as good as CT scan in the evaluation of kidney tumor(s). Objectives: To provide preliminary data to enable subsequent development of an MRI protocol at 3 Tesla for evaluation of renal tumors and their vascular supply, which can be adopted in patients who are unable to undergo CT evaluation.

Detailed Description
-----------------
3 Tesla MRI is a new MRI scanner that in theory, can produce better images than currently available MRI scanners. Currently, CT scanning is the main way of evaluating tumors in the kidneys. However, there are some patients who cannot have CT scans (usually, because of allergy to CT contrast medium or kidney damage/failure). It is with these patients that researchers are hoping to use a technique (using MRI) that is as good as CT scanning. As part of your standard of care, your doctor is requesting a CT scan of your kidneys and abdomen. If you take part in this study, you will have a 3 Tesla MRI scan of your kidneys and abdomen as well, within 15 days following your routine CT. For the 3 Tesla MRI scan, you will be lying flat on the MRI scanner, and as with a regular scan, you will have a small needle placed in a vein in your arm to inject the contrast dye. A diuretic, Lasix, will be given to help distend the internal tubes in the kidney to help view your kidney better. The MRI scan will take between 1-2 hours to perform. As with regular scans, you may be asked to hold your breath on occasions. If there is a concern about your kidney function, blood (about 1 teaspoon) will be drawn to test your kidney function before you have the MRI. Your participation in the study will be complete at the end of the MRI scan. The routine CT scan will be the main decision making examination. However, if the MRI shows something different and potentially relevant to your care, your referring physician will be informed. This is an investigational study. A total of 45 patients will take part in this study. All will be enrolled at MD Anderson.

Eligibility Criteria
-----------------
Inclusion Criteria: Patients who have undergone or are due to undergo a CT Renal Protocol study, in the course of pre-operative evaluation for renal tumor surgery. Written informed consent will be obtained. Exclusion Criteria: Patients with an allergy to both gadopentetate dimeglumine and gadodiamide MRI contrast agents.
