Peripartum pubic symphyseal rupture is diagnosed on clinical grounds. Although the diagnosis may be supported by radiography, which shows diastasis of the pubic rami, magnetic resonance imaging (MRI) can visualize the nature of the soft tissue injury.
Two puerperas thought clinically to have pubic symphyseal rupture were imaged with MRI. In addition to diastasis of the pubic rami, clefts were seen within the symphyseal cartilage, extending the entire breadth of the joint. The clefts were filled with fluid or hemorrhage, seen in T1- and T2-weighted images. The fluid was encapsulated within the joint by the surrounding ligaments. Four control normal puerperas, who had vaginal deliveries but were asymptomatic, showed none of the aforementioned findings.
MRI can visualize the soft tissue injury seen in pubic symphyseal rupture and may be used to confirm the clinical diagnosis.
产时耻骨联合破裂依靠临床诊断。虽然X线摄影可显示耻骨支分离以支持诊断，但磁共振成像（MRI）能够直观显示软组织损伤的情况。
两名临床上疑似耻骨联合破裂的产妇接受了MRI检查。除耻骨支分离外，耻骨联合软骨内可见裂隙，延伸至关节的整个宽度。在T1加权像和T2加权像上可见裂隙内充满液体或血液。液体被周围韧带包裹在关节内。四名经阴道分娩但无症状的对照正常产妇未出现上述任何表现。
MRI能够直观显示耻骨联合破裂中的软组织损伤，可用于临床诊断的确认。
