When radionuclide imaging is performed using Tc-99m-labeled erythrocytes or human
serum albumin, serial planar images are routinely acquired to detect the site of …

The present case was a 62-year-old man who presented with relapsing severe colonic
diverticular bleeding. A diverticulum with fresh coagula was identified in the ascending colon …

Acute gastrointestinal bleeding is often intermittent and the bleeding source may be difficult
to locate, resulting in delay of potentially life-saving treatment. The aim of this study was to …

A 79-year-old man with melena was suspected of having small bowel bleeding because
upper and lower endoscopic findings were negative. Technetium-99m-labeled red blood …

A 52-YEAR-OLD woman presented with a five-day history of dark stools and nausea.
Physical examination revealed a blood pressure of 148/106 mm Hg, pulse of 84/rain, and …

Although Tc-99m-labeled RBC SPECT is sensitive for detection of intestinal bleeding, it
cannot provide a high degree of specific anatomic information. We present a case of …

Arteriography to detect gastrointestinal bleeding, which is often intermittent, is only likely to
yield diagnostically useful information if the patient is actively bleeding at a rate of greater …

Acute gastrointestinal bleeding may be localized using noninvasive radionuclide methods.
We have favored the use of technetium-99m sulfur colloid with sequential imaging because …
