OBJECTIVE: The aim of this study was to propose a quantitative analysis method using technetium (Tc)-99m-labeled red blood cell RBC imaging to allow calculation of the amount and the rate of gastrointestinal (GI) bleeding.
MATERIALS AND METHODS: Rabbit models of fixed-GI and continuous-GI bleeding were created using catheter infusion. The amount and rate of bleeding were calculated and compared with the infused amount and rate.
RESULTS: No significant differences in calculated or actual amounts or rates of GI bleeding were observed after 2, 4, and 6 hours of catheter infusion of Tc-99m-RBCs.
CONCLUSIONS: The proposed quantitative analysis method using Tc-99m-RBCs GI scintigraphy can accurately calculate the actual amount and rate of GI bleeding.
