| Abstract | 「要旨」脳炎患者17例を対象に脳血流SPECTを延べ29回施行し, MRI所見と比較検討した. 発症1週以内の急性期に評価した6例中5例(83.3%)に局所高集積域を認め, 2週以後の亜急性期〜慢性期に検査した23例中16例(69.6%)では, 局所的な低集積域を認めた. 経過観察し得た高集積19病巣中6病巣(31.6%)は経過中に低集積域に変化し11病巣(57.9%)は正常集積に回復した. 急性期〜慢性期を含めて, 初回検査時低集積を示した51病巣中17病巣(33.3%)は, 経過中に正常集積に回復した. MRIとの比較では, SPECTにて高集積を呈した18領域中8領域(44.4%)に皮質の肥厚, T2強調画像上の高信号病変が認められた. また低集積を呈した74領域中36領域(48.6%)で病巣に一致した. 皮質の肥厚, 脳萎縮, T2強調画像上の高信号病変が認められた. また, MRI上は無所見であった212領域中48領域(22.6%)にSPECT検査にて異常所見が認められた. 脳炎の病態の把握, 経過観察に脳血流SPECT検査が有用であった. |

| Abstract | Twenty-nine rCBF SPECT study was done in 17 patients with encephalitis. Five of 6 patients (83.3%) showed regional high uptake in acute phase within a week after onset and 16 of 23 studies (69.6%) showed regional low uptake in subacute and chronic phase. Six of 19 lesions (31.6%) with regional high uptake changed to low uptake and 11 lesions (57.9%) improved to normal uptake on follow up studies. Seventeen of 51 lesions with low uptake (33.3%) improved to normal uptake. On the comparative study with MRI, 8 of 18 (44.4%) high uptake area showed cortical thickness or high intensity on T2 weighted images. Thirty-six of 74 low uptake area (48.6%) showed cortical thickness, brain atrophy or high intensity on T2 weighted images. Forty-eight of 212 regions (22.6%) with normal MRI findings showed abnormal accumulation of cerebral tracer on rCBF SPECT studies. rCBF SPECT was useful tool for diagnosis and follow up management in patients with encephalitis. |
