Symptoms of patients with silent ischemia as detected by thallium stress testing.

This study was undertaken to determine whether patients with silent ischemia (SI) (a positive thallium stress test without chest pain) have nonchest-pain symptoms that might serve as "anginal equivalents." Two hundred ninety-four individuals on completing a stress test were requested to score ten symptoms on a questionnaire (0 absent; 3 severe). Forty-three with a positive test had pains (chest, back, arm, and/or jaw) (no SI), whereas 93 with a positive test did not (SI).

Infected cyst localization with gallium SPECT imaging in polycystic kidney disease.

This case report describes a 43-year-old woman with polycystic renal disease and cyst infection. Infected cysts of the left kidney were successfully localized with Ga-67 citrate SPECT imaging and CT. Other imaging, including planar gallium imaging, was helpful diagnostically, but could not determine the exact location of infection within the kidney.

Diagnostic significance of unusual small intestinal pattern on technetium-99m DISIDA hepatobiliary imaging studies.

During the intestinal phase of hepatobiliary imaging studies in four patients, unusual small intestinal abnormalities were noted. These findings were correlated with surgery in three patients. Recognition of these patterns gives additional clinical information of significant diagnostic value.
