CT Scan
diagnosticA CT scan, or computed tomography, combines many X-ray images taken from different angles to build detailed cross-sectional pictures of bones and tissues. It shows far more detail than a standard X-ray, especially of bone structure, fractures and joint surfaces. You lie still on a table that moves through a ring-shaped scanner, and the scan itself usually takes only minutes.
