Abstract
MANY disorders can lead to radiological abnormalities of the sacroiliac joints. Some present a characteristic appearance, while others may be diagnosed by analyzing both the appearance and the distribution of findings (Table).1 This article describes the radiological features of these various disorders that often allow an exact diagnosis to be made. Method of Evaluation The standard method of radiological evaluation of the sacroiliac joints varies among different institutions. Although oblique views are widely used, the best angle of obliquity is difficult to determine, and visualization of the joints may not be optimal. A common routine examination combines a straight anteroposterior roentgenogram of the pelvis (see Figs 3, 4, and 6) with a second anteroposterior film obtained with cephalad angulation. Such technique results in the sacroiliac joints being viewed more directly (see Figs 2 and 5). Some authors have suggested that computed tomography is superior to conventional radiography in the
