Multidetector computed tomography (MDCT) has been developed for the purpose of reducing the scan time and enlarging the scan coverage. In benefit of multiple arrays of detectors along with faster gantry, MDCT has now become an inevitable diagnostic tool for various kinds of musculoskeletal diseases. Three-dimensional reconstruction images are the basic method in all kinds of musculoskeletal images. Multiplanar reformat, surface rendering, and maximum intensity projections are frequently used techniques. Occult fractures in complex anatomic regions, joint disease evaluations including internal derangement of the joints, and cartilage lesions can be assessed accurately with MDCT. Indirect intravenous contrast enhanced angiographic images are much improved from the previous version of CT or MRI in terms of differentiating individual phases of contrast filling. MDCT is a 3D-oriented diagnostic tool, and one must acknowledge appropriate scan parameters in order to obtain the best 3D results. MDCT is one of the hottest imaging tool in the field of diagnostic radiology. Sixty-four detector CT is now popular, and 512 and more advanced detectors such as 2-dimensional fat panel CT are expected to appear in the near future. A thorough knowledge on the application of MDCT is necessary in order to use this state-of-the-art imaging equipment efficiently in our daily practice.
