4y F Maltese Terrier with suspected portosystemic shunt. Images are ordered from ventral to dorsal (a–e) after subtraction. There is a
congenital extrahepatic shunt vessel traveling from the portal vein (a: P), through the splenic vein (a: S), and then dorsally (b–d: arrows)
to join the azygos vein (e: AZ). The MIP image shows the entire course of the shunt vessel (f). The gastroduodenal vein (f: GD) joins the
portal vein cranial to the shunt origin. The portal vein decreases in diameter after the shunt exit (f: P). See page 507 for Legend for
