Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! The image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more
Too long to list: Ct scan is a form of x-ray in which the radiation source & detectors rotate around the patient as she moves through the plane of the beam. As with all x-rays, it measures different density to the radiation, but the computer takes the raw data and reconstructs cross sectional images like slices of bread. While still limited to differences in density, it can resolve to a few millimeters. ...Read more

You will be asked to fast for several hours beforehand. Then, you will probably be given some flavored contrast to drink, which is a type of dye to make the scans show more detail. You may also need to have an IV inserted to get IV contrast.

Best view of abdomen: The abdominal ct is the best quick view of the entire abdominal cavity. It provides a great picture of all organs and the abdominal wall, as well as the spine. This study can see everything from cancer to kidney stones to hernias to vertebral fractures to foreign bodies. Usually, you are given contrast which provides an even better view. Downside, radiation exposure similar to 400-500 x-rays. ...Read more
Tri-phasic CT: Tri-phasic ct scans are used to evaluate the structure, the blood vessels and the nature of the organs. The three phases are: 1) before the intravenous contrast is given; 2) the arterial phase, when the dye is given rapidly as an injection, the effect is that it goes to the heart as a bolus and then to the aorta as a bolus, like an arteriogram; 3) the venous phase or equilibration phase. ...Read more
Several things: Can be seen on ct scan. The oral contrast helps deliniate some of the intestinal findings. Other organs are also seen such as liver, pancreas, gallbladder, aorta, lymph nodes, kidneys, urinary bladder, uterus or prostate, vertebral column, etc. Some structures are seen better than others. ...Read more
What is the likelihood that I could die from oral and IV contrast for an abdominal CT scan. I'm terrified and I don't know why. Please help.
Discuss with doc: These dyes have had enormous clinical use and rarely cause any problems. The only risk is ultra rare sensitivity which usually occurs in those who have had exposure to these in the past. Discuss with your doctor who will be administering these to you to put you at ease. You might need some pre-test anti-anxiety medication. ...Read more
Possibly: An abdominal CT examines the abdomen from the belly button up to the bottom of the chest. A pelvic CT examines the body from the belly button to the bottom of the pelvis. The test for the 'abdomen' is generally ordered as CT of the abdomen and pelvis with and /or without contrast. A CT of the abdomen and pelvis should detect a hernia. Sometimes an ultrasound is ordered in addition to and/or instea ...Read more
Depends: On why the ct scan is being done. Do not know if you mean drinking fluids like water & juice which are fine right after the radiology study is completed unless there are concerns of bowel obstruction. If you mean drinking alcohol then that depends mostly on why the ct scan was being done. Ask the radiologist or your doctor ordering the study. ...Read more
I am so worried about my son because he has had two abdominal CT scan. One at 10 mSv at age 4 and the other at 6mSv two weeks ago and he is now eight.
Balance info vs risk: A CT scan can give valuable information regarding disease process but does carry its risk which increases the younger a person is and is dose related. Studies on people exposed to radiation are ongoing, and if total exposure is limited to the 16 mVs, then lifetime increase in cancer risk due to the radiation is still less than 1%. This is in addition to other genetic, disease and environment. ...Read more
Is a one-year-old abdominal CT scan that detected Nutcracker syndrome too old to look at for a second opinion?
Not too old: Second opinions can be given on any study. If your symptoms have gotten worse, then a newer study may show more disease, but the old study may still contribute some information to the diagnosis. You can contact me on my profile by pressing Send Message to start a consult. ...Read more

Many things: In general areas of abnormal growth such as a tumor or fluid cyst, or areas of swelling such as inflammation or infection.

Lucky you-you got 2: There is probably a long list of very rare things--but accessory (extra) spleens are not uncommon and most radiologists are comfortable is identifying them. Never know when an extra spleen might come in handy. ...Read more
Can an abdominal CT scan with and without contrast detect micronodular adrenal adenomas? What's the false negative possibilities?
Adrenal adenomas: With most gland problems, first figure out if the hormones are elevated. If so, THEN go looking for the tumor. This is because all glands form nodules, but these nodules often have no consequence. If you have a hormone elevation (Cushings, pheo, aldosteronoma) and the source is the adrenal, the CT will almost always find it. But this is complicated. See your Endocrinologist. ...Read more
Before my abdominal CT scan the technician gave me a big glass of water and said I shld drink and finish it up. What is that for? Thanks?
Water as contrast: Ct uses contrast both positive and negative to assess mucosa of bowel. Positive contrast usually contains iodine or barium to be seen on ct. Negative contrast can use water to see mucosa. One glass of water would show the stomach well. For the small bowel multiple glasses of water have to be ingested beginiing hours before the ct, called ct enterography. ...Read more
I did an abdominal CT scan and one of the things it showed was degenerative bone changes. What can cause this in a young adult? I'm only 26.
Do not worry:
Wear and tear on our bodies happens all of the time. The question that needs to be asked is: "are the degenerative changes unusual for the patient's age? "
current ct technology is capable of clearly showing structures 2 mm (a little bigger than 1/16 of an inch). We see many things which may not clinically significant, i.e., give the patient problems or cause pain. ...Read more
My abdominal CT scan says “ovoid hypodense estructure in retroperitoneum” 3.6x 4x 3.5 cm, Dr says it’s probably benign but I’m concerned. Any help?
Difficult: To venture a guess without additional info or viewing the images. If it is a cyst it may be innocuous. If it is a solid mass it might require further work up. ...Read more
Depends on depth: During an EGD, if the operator (GI doc) is experienced, he/she can perform an endoscopic ultrasound, which is an ultrasound probe placed at the end of the scope. Then, depending on how deep the nodule is located, it could be seen. Very large nodules (more than 5 cm in size) close to the wall will "indent" the stomach & can be seen that way as well. US is limited to about 1 cm nodules and larger. ...Read more
