title: Quantitative analysis of radioisotopic angiography in trophoblastic neoplasia.
abstract: The diagnostic significance of radioisotopic angiography in the clinical management of trophoblastic neoplasia was studied by analyzing the patterns of radioisotope (RI)-dynamic curve obtained by processing sequential image with a computer, and an attempt was made to express numerically the size of tumors present in vivo. It was demonstrated that the total activities of RI in the abnormal phase of RI-dynamic curves in trophoblastic neoplasia were closely correlated with the sizes of the intrauterine tumors actually resected.
