ULTRASONOGRAPHY Ultrasonography of the Testis—Correlation with

Ultrasonic study of testicular disease and paratesticular masses was car-ried out in 20 cases. In eight of these, comparison was made with pertechne-tate perfusion studies performed concurrently. Testicular torsion was well revealed by both techniques. Acute orchitis, in the early stages, was shown more clearly by radiotracer, unless there was associated epididymal swell-ing or hydrocele. Chronic complications of inflammation, particularly ab-scess formation, were seen best by ultrasonography. Paratesticular masses could be studied only by ultrasound. These included both solid and cystic masses due to chronic epididymitis. J Nucl Med 19: 615-618, 1978 Although the testis is readily examined by simple measures such as palpation and transillumination, the diagnosis of various diseased states is not always clear. It may be anticipated that sonography would have much to add, since the organ and surroundin
