Abstract

Tearing of the acetabular labrum is a common cause of chronic hip pain. MR arthrography (MRA) of the hip is the imaging procedure of choice for the evaluation of acetabular labrum. Familiarity with the various imaging findings of MRA of the hip allows recognition of normal variants and differentiation from true pathologic conditions. This article comprehensively reviews the technical aspects and interpretation of MRA of the hip. The appearances of normal and abnormal labra in MRA are discussed. Potential pitfalls in labral tear interpretation, such as sulci around the hip, normal variants of the labrum and plicae, and osseocartilaginous and soft tissue lesions identified on MRA of the hip are also described.

비구순 파열은 만성 고관절 통증의 흔한 원인 중 하나이며, 고관절 자기공명관절조영술은 비구순의 평가를 위한 중요한 검사 방법이다. 비구순의 정상변이와 비정상 상태를 구별하여 정확한 진단을 하기 위해서는 고관절 자기공명관절조영술에서 보이는 다양한 영상 소견을 숙지하는 것이 필요하다. 본 글에서는 고관절 자기공명관절조영술 시행의 기술적인 방법 및 영상해석에 관해 종합적으로 검토하고자 한다. 고관절 자기공명관절조영술에서 비구순의 정상 및 비정상 소견을 살펴본다. 또한 비구순 파열과 유사하게 보여 감별이 필요한 고관절 주위틈, 비구순의 정상변이, 주름 등에 대해 알아보고, 고관절 자기공명관절조영술에서 볼 수 있는 골연골 및 연조직 병변 등의 소견에 관해 기술한다.
