| Abstract | 「要旨」髄膜腫患者に対し, 99mTc-hexamethyl-propylene-amine-oxime(HMPAO)と99mTc-ethyl cysteinate dimer(ECD)を使用した脳血流SPECTを施行した. 99mTc-ECD SPECTでは腫瘍部位は集積低下を示したが, 99mTc-HMPAO SPECTでは逆に高集積を示した. また, Matas test(用手総頸動脈圧迫法)を付加し, 腫瘍血流を減じた状態で施行した99mTc-HMPAO SPECTでは, この高集積は消失した. 99mTc-ECDと99mTc-HMPAOはともに局所脳血流をよく反映する製剤とされているが, 以上の所見は両者の集積機序に差異があることを示すものと考えられた. |

| Abstract | [Summary]99mTc-ECD SPECT and 99mTc-HMPAO SPECT with or without Matas test were performed in a 62-year-old woman with meningioma in the left anterior cranial fossa. After injection of 740 MBq 99mTc-ECD or HMPAO, 64 projection images were collected with a rotating Gamma camera. Matas test was carried out by compressing the left common carotid artery for about one minute immediately after RI injection. Although 99mTc-ECD SPECT showed non-accumulation in the tumor, 99mTc-HMPAO SPECT demonstrated increased accumulation in it. This area of increased accumulation disappeared on 99mTc-HMPAO SPECT with Matas test which causes decrease in blood flow of the tumor. These findings suggest 99mTc-ECD and 99mTc-HMPAO have a different mechanisms of accumulation in the meningioma. |
