| Abstract | 「要旨」左肺動脈欠損症で, 99mTc-MAA肺血流スキャンや81mKr換気スキャンのみならず, 99mTc-HSAによるRIアンギオグラフィと時間放射能曲線が患側の肺血流を評価する上で有用であった一例を報告する. 症例は32歳男性で, 99mTc-HSAによるRIアンギオグラフィの早期像では左肺野の完全欠損が認められたが, 後期像ではRIの分布が認められた, 両側肺門に関心領域を設定した時間放射能曲線では, 側副血行路を介した肺血流の存在が示唆された. 肺血流に相当すると思われる曲線下の面積比は右対左4.6であった. 一方, X線CT像より求めた肺の容積比は右対左2.7となったことより, 容積当たりの血流は右肺に比べ左肺で低下していることが示唆された. 以上, 肺血流スキャンに加えて, 肺動脈欠損症におけるRIアンギオグラフィの有用性が示された. 「I. はじめに」肺血流の評価には99mTc-MAA血流検査が有用であり, 肺動脈欠損症における99mTc-MAAスキャンの有用例もすでにいくつか報告されている. |

| Abstract | [Summary]We reported a case with agenesis of the left pulmonary artery, in which radionuclide angiography with 99mTc-HSA and time activity curve(TAC)were useful in evaluating pulmonary perfusion in the effected lung. The case involved a 32-year-old male, who underwent nuclear medicine examination including 99mTc-MAA scanning, 81mKr scanning and 99mTc-HSA angiography. 99mTc-MAA and 81mKr scanning showed the perfusion defect and decreased ventilation in the effected lung, respectively. On the other hand, the delayed images of 99mTc-HSA angiography showed the existence of perfusion in the effected lung, although the early images showed the perfusion defect in the same lung. The TAC whose region of interest was placed on the hilus showed that the effected lung was gradually filled with the blood flow through the collateral pathways. In addition, the ratio of area under the TAC on the contralateral lung versus the effected lung was 4.6, while the volume ratio of the contralateral lung versus the effected lung obtained from X-ray CT images was 2.7. Therefore, it was suggested that the perfusion per volume in the effected lung was decreased, compared with that in the contralateral lung. It was concluded that 99mTc-HSA angiography was useful in evaluating the perfusion of the effected lung in a patient with agenesis of the left pulmonary artery. |
