Like many other advances in science, invention of the CT scanner was not a singular event, but the product of advances at the forefront of science and technology. Ledley's greatest contributions to science, in fact, occurred decades before when he laid out the principles of applying computers in medicine (See: Reasoning Foundation of Medical Diagnosis) and computerized image analysis. When computers became sufficiently powerful to allow reconstruction of transferse images, Ledley was in the forefront, along with Godfrey Hounsfield in developing such machines. Hounsfield's machine was first, but very limited in its applications since it could not effectively reconstruct images including air or bone. Ledley's machine built on his previous success in building computers for pattern recognition and image analysis, and used mathematical algorithms developed by Allan Cormack. The Ledley machine (termed the ACTA) was the first that could effectively image large portions of the body, and he received the patent for this invention.
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.
uuuh lets seee........ a cat scan!

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?
