BUN 13, creat 1.19 GFR 50. Is it safe to have a CAT scan w/ contrast?

Yes: This is basically a normal creatinine especially if you are a solid-built lady. When I was working out every day, my creatinine ran 1.6 or 1.7. The GRF 's estimated are subscientific -- there is an adjustment for race "because black people are more muscular." You are not a kidney patient unless there is something else. Best wishes. ...Read more

I had a cat scan with contrast. No significant flow identified within inferior mesentteric artery.What to do, is this bad.

Could be worse: 3 arteries supply your small and large bowel, and they have lots of connections between them, so narrowing of only 1 is not terrible. However, if another gets narrow, you could develop intestinal ischemia, which is not good. Also, if the ima is narrow, what other arteries are also narrow - maybe in the brain or legs? Please take this seriously and make a plan with your health care provider. ...Read more

Is it rare to have to take a second CT scan with contrast because the contrast did not reach the lower left quadrant?

Is it rare to have to take a second CT scan with contrast because the contrast did not reach the lower left quadrant?

This is common.: When you drink contrast for a CT scan, it may take a long time for your intestines to get the contrast from the stomach to the rectum. Typically, CT scans are done 1 hour after you've begun drinking. This can be enough time to fill most of the bowel, but not all of it. Radiologist may request a 2nd scan if there is some question about the colon that wasn't answered on the 1st scan. ...Read more
