title: Digital indirect portography.
abstract: Thirty-eight patients underwent digital indirect portography with arterial injections of dilute contrast medium. The portal system was seen in 37 patients. Compared with conventional portography, the technique offers many advantages, including increased sensitivity and earlier visualization of the portal venous system, lower contrast loads, and lack of need for vasodilators. Digital indirect portography is an excellent method for evaluating the portal venous system.
