The radiation used in CT scans can damage body cells, including DNA molecules, which can lead to radiation-induced cancer. [148] The radiation doses received from CT scans is variable. Compared to the lowest dose X-ray techniques, CT scans can have 100 to 1,000 times higher dose than conventional X-rays. [149]
A full-body scan is a scan of the patient's entire body as part of the diagnosis or treatment of illnesses. If computed tomography ( CAT ) scan technology is used, it is known as a full-body CT scan , though many medical imaging technologies can perform full-body scans.
X-ray computed tomography (CT), or Computed Axial Tomography (CAT) scan, is a helical tomography technique (latest generation), which traditionally produces a 2D image of the structures in a thin section of the body. In CT, a beam of X-rays spins around an object being examined and is picked up by sensitive radiation detectors after having ...
Coronary CT angiography (CTA or CCTA) is the use of computed tomography (CT) angiography to assess the coronary arteries of the heart.The patient receives an intravenous injection of radiocontrast and then the heart is scanned using a high speed CT scanner, allowing physicians to assess the extent of occlusion in the coronary arteries, usually in order to diagnose coronary artery disease.
Using image-guidance—either by a computed tomography (CT) scan or by ultrasound—the interventional radiologist maneuvers the cryoprobe toward the location of the tumor. Next, the cryoprobes are inserted into the tumor to begin freezing it with a gas called argon, creating an "ice ball" over the entire tumor to freeze it for about ten minutes.
