目的:评价螺旋CT在前列腺癌诊断中的价值。方法:回顾性分析经病理证实的12例前列腺癌CT表现,11例行平扫和增强,1例仅行平扫,扫描层厚和间距均为5mm。结果:12例前列腺癌中,前列腺边缘隆起者占90%,局限性前列腺密度减低或不均匀者占89.6%,治疗前准确率达86%。结论:前列腺边缘结节状隆起和边缘毛糙。前列腺局限性密度减低是CT诊断前列腺癌的主要征象。膀胱精囊角消失、精囊腺增大、膀胱侵犯、盆腔淋巴结肿大是其间接征象。
Objective: To evaluate the value of spiral CT in the diagnosis of prostate cancer. Methods: CT findings of 12 cases of prostate cancer confirmed by pathology were retrospectively analyzed. Eleven patients underwent plain scan and contrast enhancement. One patient underwent plain scan only. The scan thickness and interlacing distance were both 5mm. Results: In 12 cases of prostate cancer, prostatic erection accounted for 90%, localized prostate density decreased or uneven accounted for 89.6%, 86% accuracy before treatment. Conclusion: Prostate nodules with raised edges and rough edges. Prostatic limitations density reduction is the main CT diagnosis of prostate cancer. Seminal vesicle angle disappear, seminal vesicle increased, bladder invasion, pelvic lymph nodes is an indirect symptom.
