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

Is computed tomography angiogram cta a very common procedure?

CT angiogram: It is being done much more often when it is necessary to visualize blood vessels (for example to see if there's a blockage). There is some radiation involved but it is considered much less "invasive" and has less complications than the regular type of "angiogram", where blood vessels are visualized by inserting thin tubes called catheters directly into them to inject a dye. ...Read more

What is the definition or description of: computed tomography angiogram cta?

Artery test: A special type of ct scan where intravenous dye is injected, and imaging is timed so that the arteries of interest are maximally opacified by the injected dye. Ct images in this test are acquired rapidly, and the actual scan will likely be done in a matter of seconds. Historically, evaluating the arteries required threading a catheter into the artery of interest. Cta is non-invasive. ...Read more

Which procedure exposes patients to more radiation: a bone scan or a computed tomography?

Which procedure exposes patients to more radiation: a bone scan or a computed tomography?

Sometimes same dose: Background radiation at sea level: 3 msv per year, denver residents get: 6 msv per year, cross country flight: 0.02 msv, x ray chest: 0.06 msv, ct head: 3 msv, ct chest: 5 msv (equivalent to 100 chest xrays) ct abdomen: 5-10, average bone scan 6.5 msv. Radiation depends on size of patient." radiation affects growing body in children more than adults. Doses to children are much less. ...Read more

No: A routine ct does not cause pain. Even if contrast is given, only a small IV is placed and no pain medicine is necessary. If you have an underlying condition that causes pain and limits your ability to lay on your back you may need to talk to the doctor requesting the exam to see if you should take medicine prior to the exam. ...Read more

Ct Scan (Definition)

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
