Magnetic resonance imaging (MRI) is often "one stop shop" for evaluating female pelvic masses that helps in diagnosis, staging, and restaging of these tumors. A pelvic mass can arise from any tissue present within the pelvis. Although most masses in the female pelvis arise from the reproductive organs, masses may also arise from the gastrointestinal tract, urinary system, adjacent soft tissues, peritoneum, etc. It may not always be possible to determine the site of origin or distinguish these masses based on imaging characteristics. However, familiarity with the clinicopathologic and MRI features of most common pelvic masses helps in narrowing the differential diagnosis. Diagnosis of these masses needs a holistic approach as required for any tumor including clinical history, laboratory data, and imaging characteristics. We focus on MRI characteristics of commonly encountered pelvic masses. A compartmental imaging approach is discussed in this article that helps in identifying and characterizing these masses.
磁共振成像（MRI）通常是评估女性盆腔肿块的“一站式检查手段”，有助于这些肿瘤的诊断、分期及再分期。盆腔肿块可起源于盆腔内的任何组织。虽然女性盆腔中的大多数肿块起源于生殖器官，但肿块也可能起源于胃肠道、泌尿系统、邻近软组织、腹膜等。根据影像学特征，可能并不总是能够确定肿块的起源部位或区分这些肿块。然而，熟悉最常见盆腔肿块的临床病理和MRI特征有助于缩小鉴别诊断范围。对这些肿块的诊断需要采用与任何肿瘤一样的整体方法，包括临床病史、实验室数据和影像学特征。我们重点关注常见盆腔肿块的MRI特征。本文讨论了一种分区成像方法，有助于识别和描述这些肿块。
