Improved detection and localization of lower gastrointestinal tract hemorrhage by subtraction scintigraphy: phantom analysis.
UNLABELLED Acute lower gastrointestinal tract hemorrhage (LGIH) has significant morbidity and mortality outcomes. Although several causes of LGIH can be life threatening, most can be effectively treated; therefore, early detection and accurate localization of bleeding sites are critical for successful patient management. METHODS This study was a phantom experimental study with a repeated-meas...
متن کاملImproved detection and localization of lower gastrointestinal hemorrhage using subtraction scintigraphy: clinical evaluation.
UNLABELLED Does subtraction scintigraphy improve the diagnostic utility of scintigraphic evaluation in acute lower gastrointestinal hemorrhage? METHODS This research was a retrospective clinical study using a repeat-measures design of randomized control and experimental groups. A single patient dataset provided both the control group (conventional scintigraphy) and the experimental group (con...
متن کاملFalse positive GI bleed on Tc-99m RBC scintigraphy due to ileal varices.
Tc-99m labeled RBC scintigraphy is commonly employed in the evaluation of acute gastrointestinal bleeding. On Tc-99m RBC studies gastrointestinal bleeding is seen as an initial focus of increased radiotracer activity that on subsequent images increases in intensity and changes position in a pattern that conforms to segments of bowel. We report a case of a patient with multiple episodes of hemat...
متن کاملAccuracy of 99mTechnetium-labeled RBC Scintigraphy and MDCT With Gastrointestinal Bleed Protocol for Detection and Localization of Source of Acute Lower Gastrointestinal Bleeding.
BACKGROUND Acute lower gastrointestinal bleeding (LGIB) is a major cause of morbidity and mortality. Multidetector row computed tomography (CT) with gastrointestinal (GI) bleed protocol is a novel diagnostic technique for detecting and localizing LGIB. Being rapid and noninvasive, it may be useful as a first-line modality to investigate cases of acute LGIB. GOALS To assess and compare diagnos...
متن کاملCost-effectiveness analysis of subtraction scintigraphy in patients with acute lower gastrointestinal tract hemorrhage.
UNLABELLED (99m)Tc-labeled red blood cell scintigraphy is a powerful detection and localization tool that may be confounded by false-positive and false-negative findings. Subtraction scintigraphy has been used in the evaluation of acute lower gastrointestinal tract hemorrhage (LGIH) to reduce the impact of interpretive confounders. The aim of this investigation was to evaluate the cost-effectiv...
