Conclusion

RBC scintigraphy plays a complementary role to colonoscopy and angiography in the evaluation of lower GIB and should be utilized prior to those more invasive procedures, which often fail to localize and control lower GIB due to intermittent bleeding. The fact that radionuclide imaging is noninvasive, safe and can detect slower bleeding rates than other conventional imaging methods makes it useful in hemodynamically stable patients who are suspected of having intermittent or low rates of GI hemorrhage.[18] In addition, RBC scintigraphy helps to stratify high-risk patients who would most benefit from aggressive intervention from those who can be managed medically.
