Prostate cancer is a common entity in elderly men. Diagnosis is based on histology obtained from transrectal ultrasound-guided biopsies, whereas magnetic resonance (MR) imaging can be used for local staging of prostate cancer. MR features of extracapsular extension are particularly important as it leads to upstaging of the tumour and significantly affects both treatment and prognosis. The purpose of this review was to demonstrate the MR imaging appearance of different stages of prostate cancer. MR spectroscopy can also aid in improving the diagnosis. Accurate staging can ensure appropriate management and prevent recurrence due to inadequate treatment.

前列腺癌是老年男性常見的疾病。診斷前列腺癌可經直腸超聲引導的活檢而獲得組織作化驗，而磁共振（MR）成像可用於前列腺癌的局部分期。MR特徵有助了解前列腺癌是否有外擴散的跡象，這點相當重要，因為外擴散會導致腫瘤評分升級，並會影響治療和預後。本文探討前列腺癌不同階段的MR成像。MR波譜有助於診斷。準確的分期對於確保適當的治療有重要意義，從而防止因治療不徹底而造成復發。
