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.

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.

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 moreSee 1 more doctor answer
Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk.
