Abstract

A group of 32 patients with a histological diagnosis of prostate cancer underwent transrectal ultrasound (TRUS) and magnetic resonance imaging (MRI) to stage the disease. TRUS was more sensitive in the detection of tumour and in the detection of direct extracapsular spread. MRI was more sensitive in the detection of tumour involvement of the seminal vesicles and bladder base. MRI allowed the detection of lymphadenopathy and bone metastases in the lumbosacral spine and pelvis. During MRI the short tau inversion recovery (STIR) sequence was found to be particularly useful for the detection of tumour spread. TRUS and MRI are complementary investigations and for the accurate staging of prostatic malignancy both investigations should be used.

摘要

一组32例经组织学诊断为前列腺癌的患者接受了经直肠超声（TRUS）和磁共振成像（MRI）检查以对疾病进行分期。TRUS在检测肿瘤及直接包膜外扩散方面更敏感。MRI在检测精囊和膀胱底部的肿瘤侵犯方面更敏感。MRI能够检测腰骶部脊柱和骨盆的淋巴结病及骨转移。在MRI检查过程中，发现短tau反转恢复（STIR）序列对检测肿瘤扩散特别有用。TRUS和MRI是互补性检查，为准确对前列腺恶性肿瘤进行分期，两种检查都应采用。
