| Abstract | 「要旨」肝腫瘍の疑われた122例を対象にSPECTの診断能を, 従来の肝シンチグラムと比較検討した. sensitivityは, 肝シンチグラム(79%)に比べSPECT(90%)で向上がみられたが, specificityは82%から87%と, あまり変化がなく, 結局正診率は, 肝シンチグラムの80%に対し, SPECTでは89%に増加した. 直径6cm以下の腫瘤90病変の検出能を比較すると, 肝シンチグラムは直径4cm以上の腫瘤でも1例見落していたのに対し, SPECTでは1.7cmの腫瘤を欠損像として描出することができた. 特に直径2〜4cmの腫瘤の検出能は, SPECTを実施することで, 有意に向上した. SPECTの検査時間は約12分と短く, 被曝線量も増加しない. SPECTは, 肝腫瘍に対するスクリーニング検査として臨床的有用性が高いと考えられた. |

| Abstract | [Summary]Clinical efficacy of single photon emission computed tomography (SPECT) for detecting small space occupying lesions (SOLs) in the liver was comparatively evaluated with conventional liver scintigraphy. 122 cases were examined with both modalitites. Conventional imaging showed 79% of sensitivity and 82% of specificity, while the use of SPECT improved to 90% and 87% respectively, so that the accuracy rate was increased from 80% to 89%. Resolution capability was investigated in 90 SOLs smaller than 6.0 cm in diameter. The total detectability was increased from 59% by conventional imaging to 73% by SPECT. Especially the detectability of SOLs in the range of 2.0 to 4.0 cm was markedly improved. The smallest SOL resolved by SPECT was 1.7 cm in diameter, whereas the conventional liver scintigraphy missed one SOL even larger than 4.0 cm. In conclusion, SPECT appears as a promissing and reliable procedure for screening SOLs in the liver. |
