Computed tomography (CT) is a radiological method that uses X-rays to produce cross-sectional images of the examined area of the body. Since the method uses X-rays, it involves radiation. For this reason, its use is avoided in pregnant women. However, with today’s advanced new devices and technologies, images are obtained while minimizing the radiation dose as much as possible to ensure patient safety.
What capabilities do 128-slice CT scanners, made possible by advancing technology, offer?
With the 128-slice CT scanners made possible by advancing technology, the speed of the examination has increased, and the thickness of the slices produced by the device has decreased. The entire body can be scanned with thin slices during a single breath-hold; by processing the continuously acquired slices on a computer, cross-sections in different planes, 3-dimensional anatomy, and fine details can be visualized. In addition, the newly developed I-DOSE technology enables high-resolution imaging with minimal radiation dose.
In what situations is CT used?
CT is a highly sensitive examination for detecting bleeding. In patients with suspected brain hemorrhage, a scan lasting just a few seconds can confirm the presence or absence of bleeding. For this reason, it is a valuable diagnostic method frequently used in emergency departments for patients presenting with suspected bleeding and for early-stage follow-up after brain surgery.
With today’s advanced multi-detector CT scanners, thin slices can be acquired to create three-dimensional images of joints. Additionally, the CT angiography method allows for detailed evaluation of blood vessels in the brain, neck, kidneys, and extremities. With cardiac coronary CT angiography, the coronary arteries can be visualized in a short time using only contrast material administered through the arm vein, allowing for a detailed assessment of narrowing and blockages. Furthermore, CT is a valuable method—second only to X-rays—for imaging the lungs.
