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

I have a CT scan with contrast they told me not to eat or drink 4 hours before. But i forgot and i ate. What will happen?

Likely nothing: The old protocols for a ct scan with contrast stated that there should be nothing by mouth 4 hours prior to the study. The rationale was to prevent vomiting thought to be caused by the intravenous contrast. The contrast agents currently used have very little likelihood of causing vomiting, so most centers will now allow you to drink clear liquids prior to the study. Still best to avoid solids. ...Read more

I have a CT scan with contrast and i was not supposed to take metformin for 48 hours but i accidentally took 1 yesterday morning will i be okay?

Could a CT scan with contrast affect a estrogen test the following day? Could it cause it to be low

Not likely: Estrogen levels fluctuate depending on where you are in your menstrual cycle. If your estrogen was very low (in the menopausal range) your fsh level should generally be high. If your fsh was not checked, or it was checked and was nomal, i would just consider asking to have your estrogen level retested. ...Read more
