| Abstract | 「要旨」確定診断が得られた肝血管腫18例40病変(組織診断確定例は5例8病変), 血管腫以外13例21病変(同10例14病変)を対象に, 99mTc標識赤血球による肝プールイメージ(SPECTおよび平面イメージ), US, CTおよび血管造影の肝血管腫に関する診断率を比較検討した. SPECTおよび平面イメージでは集積増加像を血管腫の陽性所見とし, 血流相イメージの所見は問題としなかった. 有病正診率は平面イメージが35%, SPECTが50%, USが53%, Dynamic CTが82%, 血管造影が81%で血管造影が最も良かったが, SPECTでは2.2cm以上で有病正診率が100%であった. 無病正診率は平面イメージが100%, SPECTが95%, USが81%, CTが100%, 血管造影が83%であった. SPECTでは1例の肝細胞癌(血管造影で診断確定)で偽陽性をみたが, 無病正診率はほぼ100%に近く, 血管腫に対する特異性の高さが示唆され, 2.0cm以上ではSPECTが最も正診率が高かった. 2.0cm以上の肝血管腫の診断においては, SPECTが非常に有効と思われた. |

| Abstract | The roles of planar imaging and SPECT with 99mTc-labeled RBC, US, Dynamic CT and angiography in the diagnosis of hepatic hemangioma were evaluated. The study group consisted of 18 patients with a total of 40 hemangiomas and 13 patients with a total of 21 non-hemangiomas. Among these patients, 5 patients with a total of 8 hemangiomas and 10 patients with a total of 14 non-hemangiomas were diagnosed by operation and biopsy. In all 40 hemangiomas, sensitivity for planar imaging was 35%, SPECT 50%, US 53%, Dynamic CT 82% and angiography 81%, respectively. When the tumor size was greater than 2.2 cm by SPECT and 2.8 cm by planar imaging, their sensitivity for both methods was 100%. Specificity for planar imaging was 100%, SPECT 95%, US 81%, Dynamic CT 100% and angiography 83%, respectively. One patient with hepatocellular carcinoma diagnosed by angiography showed increased uptake on SPECT. Because of the highest accuracy for SPECT in hemangioma greater than 2.0 cm, SPECT should be considered to be the method of choice for noninvasive diagnosis of hemangioma. |
