| Abstract | 「要旨」 前立腺癌のStage診断に際して, 被膜浸潤および精嚢浸潤の有無を検出することは, 根治的前立腺摘出術の適応を決定する上で重要である. 骨スキャンを含む諸検査において, Stage Bと診断された3症例について, MRIによるStage診断を直腸指診, 経直腸的超音波断層法(以下TRUSと略)による結果と比較し, また, それぞれの全摘出標本の病理組織学的所見とを対比検討した. 使用装置はRESONA(0.5 T)超電導MRI装置により, またTRUSに際しては5.0MHz, イス型ラジアルスキャナーを用いた. 症例は, 腺癌2, 前立腺導管内に生じた移行上皮癌1例で, それぞれの直腸診ではStage B1;2例, B2;1例であった. またTRUSではStage B;1, C1;1, C2;1例であり, MRIではstage B;2, C2;1例であった. これらの全摘出標本の病理組織診断ではStage B;1, C2;1, そしてD1;1例であった. MRI, TRUSともに精嚢浸潤を検出しえたが, 1例でMRIによる被膜浸潤の検出が不可能であった. |

| Abstract | [Summary] To stage the malignant prostate, digital rectal examination has been only standard clinical tool. In considering the candidate for radical prostatectomy, it is essential to determine any presence of extracapsular extension or seminal vesicle invasion. We report out experience with MRI in staging prostatic cancer to compare with each stage evaluated by digital rectal examination and by transrectal ultrasonography (TRUS), and to correspond the pathological stage in the radical prostatectomy specimen. The RESONA (0.5 T) superconductive MR imager was used. The chair-type radial scanner with 5.0 MHz probe was used for TRUS. Three patients with clinical stage B disease (adenocarcinoma;2, primary transitional cell carcinoma in the prostatic ducts;1) were evaluated in this study. On rectal examination, there were 2 with stage B1, and 1 with stage B2 disease. MRI determined 2 for stage B, and 1 for stage C2, although TRUS did 1 for stage B, 1 for stage C1, and 1 for stage C2. The pathological stage in each radical prostatectomy specimen defined 1 for stage B, 1 for stage C2, and 1 for stage D1. The MRI and TRUS improved the accuracy of staging, when compared to the stage determined by digital rectal examination alone. |
