Abstract
Although not a new development in the field of nuclear medicine, the Anger rectilinear tomographic scanner has recently gained popularity because of its clinical usefulness. A prototype of this instrument has been under evaluation at Rush Presbyterian-St. Luke’s Medical Center for the past three years, during which time over 2000 studies have been performed. Although the majority of the studies have been brain, bone, and gallium-67 scans, other routine scans have also been performed. This article describes the instrument, its basic operation, and various techniques used. Clinical evaluation of the Anger rectilinear tomographic scanner shows the system’s advantages in certain areas. It offers better information density and superior resolution away from the geometric focal plane than other rectilinear scanners with comparable collimation. The tomographic capability also allows accurate determination of lesion depth. Use of the device significantly increases the identification of pathology and reduces error and confusion resulting from normal variants.
