What is CT Scan
A CT scan, or computed tomography scan, is a medical imaging procedure that uses specialized X-ray equipment to obtain detailed cross-sectional images (slices) of various parts of the body. The CT scanner rotates around the patient, taking multiple X-ray images from different angles. These images are processed by a computer to create detailed cross-sectional views of bones, organs, blood vessels, and soft tissues.
Here are key features and uses of CT scans:
X-ray Technology: CT scans use X-rays, which are a form of electromagnetic radiation, to create images. The X-ray beams pass through the body and are detected by sensors on the other side of the patient.
Cross-Sectional Images: CT scans produce detailed images of internal structures from various angles. This allows healthcare providers to examine the body in slices, which is helpful for diagnosing conditions such as tumors, fractures, infections, and internal bleeding.
Contrast Agents: In some cases, a contrast dye may be used during a CT scan to enhance visibility of certain tissues or blood vessels. The dye can be injected into a vein (intravenous contrast) or swallowed (oral contrast) depending on the area being examined.
Versatile Applications: CT scans are used to diagnose and monitor a wide range of medical conditions, including injuries, infections, cancers, cardiovascular diseases, and neurological disorders.
Quick and Non-Invasive: CT scans are relatively quick and painless compared to some other imaging techniques. The entire procedure typically takes only a few minutes, although preparation time and scanning time may vary depending on the specific type of scan being performed.
