A CT scan that is repeated a certain number of times in the same examination period is said to be multiphasic (bi-phasic, tri-phasic, quadra-phasic). The interest is in observing a change in a parameter as a function of time. The main reason is to show the effect of intravenous contrast on CT attenuation, say pre contrast, and at one, three and five minutes post injection. By observing increased CT attenuation ( aka enhancement), or lack thereof, and it's temporal and morphological characteristics, radiologists infer the probable diagnosis.
The same can be said of pre and post contrast studies using other contrast agents or routes of administration (e.g. pre and post contrast fistulography).
do lymph nodes show on a cat scan
They are just as they say. An abdominal cat scan is just of that area and a pelvic cat scan is just of that area. Usually if an abdominal cat scan is ordered a pelvis is included so as to cover all things in both areas but if a pelvic cat scan is ordered it usually does not include the abdomen.
You do not have to stay home after a CAT scan. The procedure has no residual effects. After you leave the clinic or hospital, you can resume normal activities if you are otherwise healthy.
yes
Without. I had a cat scan this morning for that very reason and no contrast was needed.

Computerized Axial Tomography
yes
CAT SCAN is a medical procedure and so it would need to be arranged by a doctor or health-care professional.

MRI Scan and CAT Scan.
CAT scan after bone removal can not be seen by a surgeon or radioligist. Is this possible?
