a Coronal maximum intensity projection (MIP) reformatted CT image for a patient with massive small bowel GIST shows the extensive vascularity of the tumor (black arrow heads) and associated hepatic metastatic deposits (white arrow). b Aortogram shows the tumor neovascularity predominantly from the GDA and to less extent SMA. c Zoomed GDA angiogram shows the pre-embolization neovascularity and tumoral blush. d Post-embolization selective GDA angiogram demonstrates stasis and reduced tumoral blush
