6.腎腫瘤性病変の放射線検査 : DMSA腎シンチグラフィとIVPの対比(総合医用画像について)

Abstract

What the detectability of renal mass lesions was studied retrospectively is comparison between renal scintigraphy with ^<99m>Tc-DMSA and intravenous urography. Two different techniques were used in intravenous urography : one was the single or standard dose (60% water-soluble contrast medium 40ml), the other was the double or high dose (contrast medium 80ml). Films were made after injection of contrast medium at 3 min, 10 min, and 20 min, in the single dose technique, and at 0 min (nephrogram), 3 min and 12 min in the double dose technique. In summary, it is much easier to detect the renal mass lesions by renal scintigraphy with ^<99m>Tc-DMSA as compared with the single of standard dose technique, while the double or high dose technique can demonstrate readily the renal mass lesions as renal scintigraphy with ^<99m>Tc-DMSA does. The reason why the single dose intravenous urography is not effective to detect the renal mass lesions will be that the renal density (nephrogram) is not uncommon to be insufficient.
