To evaluate a diagnostic utility of digital subtraction angiography on liver tumor, 52 patients with liver tumor were studied. Contrast material on DSA was administered via either intravenous (DSA-IV) or intraarterial (DSA-IA) route. As the procedure of DSA-IV was less invasive and easier than that of conventional angiography, DSA-IV was able to be done with no events on elder patients, patients with poor to reliability to conventional angiography and out-patients. Tumors could be detected 66.7% on DSA-IV. Dose of contrast material on DSA-IA was under the half dose of conventional angiography, and clerer image was obtined (80.1%) on DSA-IA, especially of portography. Draw back of DSA were (A) difficulty in image creation due to movement of intestinal gas and intraabdominal organs and (B) limited observation field.
