摘要

本文回顧分析66位曾經接受耻骨上經腹部的前列腺超音波檢查病例，其中36位病人病理證實為前列腺癌，30位為良性前列腺肥大。前列腺癌在超音波上的徵象係以(1)病灶邊緣不規則，(2)局部的回音增強或減弱，(3)病灶局部回音不均勻，(4)前列腺之包囊有中斷現象等四點為依據。凡具上述四點中之二點或以上之徵象時即視為前列腺癌，如此檢視超音波圖後，全部66例中超音波診斷正確者有54人，其準確度為81.8%(54/66)，敏感性為86.1%，特異性為76.6%，計有31例前列腺癌獲得正確診斷（真陽性），而有7例非癌症者判為前列腺癌（假陽性）。耻骨上經腹部之前列腺掃描仍有可信賴的準確度，息者受檢並無特殊不適，宜為前列腺病變之篩檢工具。

並列摘要

From July 1982 to June 1984, 36 vertified prostatic carcinoma were scanned by suprapubic transabdominal approach in V.G.H. We retrospectively reviewed and analyzed these images. Prostatic carcinoma was characterized by focal areas of increased or decreased echogenicity with ill-defined margins, 17 of the analyses revealed focal increased echogenicity, 14 revealed focal decreased echogenicity, while 7 revealed heterogeneous echogenicity. We had the same experience of difficulty in differentiating among carcinoma, inflammation and calculi as others had. With improved technology and additional experience, the ultrasound examination should be an easy, noninvasive and accurate diagnositc tool in diagnosis of prostatic carcinoma.
