Abdominal Ct Scan Says Sigmoid And Rectum Are Loaded
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

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
Not really!: The CT will show spasm or edema (swelling of the bowel wall) but you need something such as endoscopic studies to rule out any inflammatory disease which is a serious health issue, unlike that of irritable bowel which is also painful but not progress in most cases. ...Read moreSee 1 more doctor answer

Many things: In general areas of abnormal growth such as a tumor or fluid cyst, or areas of swelling such as inflammation or infection. The intravenous contrast solution and swallowed barium help the radiologist identify and separate nearby structures and organs, and help to better visualize possible abnormalities. ...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 moreSee 3 more doctor answers
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 moreSee 2 more doctor answers
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
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
I recently had an abdominal ct scan. The report states that the bladder wall is mildly thickened. What does that mean?
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. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more
