Abstract
X-ray contrast media encapsulated within 50 nm to 10 .mu.m microspheres were shown to be a superior contrast agent for CT imaging of liver tumors. Use of the encapsulated agent resulted in significant improvement in the liver to tumor contrast ratio in CT images over prior art contrast media. The encapsulated media contrast also resulted in sustained contrast enhancement 1 hr after administration, providing the opportunity to use a lesser x-ray exposure in a single scan to discriminate cancerous tissue from normal surrounding tissue.
