A CAT scan involves the patient lying on a metal bed and being passed into either a tube or a disc that surrounds the patient, where multiple X-Rays are fired and captured by a rotating sensor, to form a multi slice image of the area being examined, showing various levels of depth.

CAT (Computerised Axial Tomography) scans are performed in medical hospitals and clinics. A physician can refer a patient for a scan at an NHS hospital and this will be carried out at no cost. However if a patient is anxious to have a CAT scan done more quickly, or if his doctor will not refer him, the procedure can be carried out privately either at a private clinic or out of normal working hours at the NHS hospital. A private scan will cost in the region of £300 to £750 dependant upon the parts of the body being scanned.
Something in a CAT scan might explain a coma, but it is not a definitive test. Just because a computer "looks normal" that is no indication that it will run. This is a crude analogy. The CAT scan images tissues. It does not evaluate how those tissues are operating - or not. Though there are a few "clues" to what is going on in a CAT scan, the scan is not the "litmus test" for actual brain operation and function. A CAT scan may be performed as part of the workup to find out why someone is in a coma. It will allow the physicians to determine if there is a "physical" cause or not. If nothing shows up, the cause of the coma must be investigated further. A coma can be a difficult thing to find a cause for.

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.
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.
Without. I had a cat scan this morning for that very reason and no contrast was needed.
