Successful Localization of the Source of Hemorrhage in Patient with Post-Whipple Surgery by ^99mTc-Labelled Red Blood Cell Scintigraphy

Figure 1

(a) Dynamic imaging sequence of a ⁹⁹Tc-labelled erythrocyte scan. The initial image (2 min image) demonstrates normal biodistribution of the radiotracer. A focus of increasing intensity is noted in the right upper abdomen at the 3 min image (red arrow). This focus of abnormal accumulation of the radiotracer shows antegrade and retrograde movement, confirming the bowel lumen appearance, and it crosses the midline several times (on cine images). This pattern is compatible with small bowel bleeding. (b) This selected late image from the ⁹⁹Tc-labelled erythrocyte bleeding scan (59 min image) shows the typical pattern of small bowel bleeding (multiple red arrows).
