title: Noncardiac clinical applications of seven-pinhole tomography.
abstract: Clinical examples of various noncardiac seven-pinhole tomographic scans are shown. In many cases, this method of emission tomography can provide a very useful extension of standard planar nuclear medicine images. Major advantages of seven-pinhole tomography include reasonable cost and improved lesion detectability due to increased image contrast. Disadvantages include rather difficult patient positioning, nonuniform plane spacing with depth, and sometimes rather long data processing times because the presently available computer algorithms are maximized for cardiac scans.
