Prostate cancer is the most common cancer among American men. It varies widely in aggressiveness, ranging from completely indolent to highly aggressive. Currently, predicting the natural history of a particular tumor and deciding on the appropriate treatment, which might include active surveillance, surgery, radiation or hormonal therapies, are based on the condition and age of the patient as well as the presumed stage of the disease. Imaging plays an important role in staging localized prostate cancer. Magnetic resonance imaging (MRI) best depicts the zonal anatomy, with a superior soft tissue resolution providing better results for tumor localization, monitoring, and local staging. Previously, the major function of prostate MRI has been in staging, and this role remains important. In this article, we introduce the reader to the expanding roles that MRI plays in the management of localized prostate cancer.
前列腺癌是美国男性中最常见的癌症。其侵袭性差异很大，从完全惰性到高度侵袭性不等。目前，预测特定肿瘤的自然病程并决定适当的治疗方法，包括主动监测、手术、放疗或激素治疗，取决于患者的病情和年龄以及疾病的假定阶段。影像学在局部前列腺癌分期中起着重要作用。磁共振成像（MRI）能最好地描绘出区域解剖结构，具有更高的软组织分辨率，能更好地进行肿瘤定位、监测和局部分期。以前，前列腺 MRI 的主要功能是分期，这一作用仍然很重要。在本文中，我们将向读者介绍 MRI 在局部前列腺癌治疗中的作用不断扩大。
