Anterior static scintigraphic image of 99mTc-radiolabeled autologous erythrocytes (a), along with a color-labeled three-dimensional reconstruction of the patient's recent computed tomography angiography of the abdomen and pelvis. Serpiginous-shaped activity on scintigraphy (b)corresponds to the enlarged gastroepiploic (arrows) and splenic (arrowheads) arteries supplying the omental carcinomatosis (asterisks). A single-slice coronal 18F-fluorodeoxyglucose-positron emission tomography/computed tomography fusion image (c) and the maximal intensity projection from the same study (d) highlight the fluorodeoxyglucose avid metastatic burden in the left lower quadrant (asterisks)

RBC scintigraphy demonstrated serpiginous areas of increased activity which did not move or change in intensity [Figure 1a]. Comparison with three-dimensional rendering of CTA acquired earlier showed enlarged gastroepiploic and splenic arteries supplying omental carcinomatosis [Figure 1b] corresponding to abnormal activity seen on scintigraphy. Recent 18F-fluorodeoxyglucose-positron emission tomography/CT demonstrated a large metastatic burden, particularly to the omentum [Figure 1c and d].
