摘要
Purpose To propose an accurate method for measuring hip capsular thickness in patients with femoroacetabular impingement syndrome and to compare of these measurement between magnetic resonance imaging (MRI) and magnetic resonance arthrography (MRA).Methods 使用之前建立的股骨髋臼撞击综合征(FAIS)患者数据库,确定 2018 年 11 月至 2021 年 6 月期间术前 MRI 或 MRA 的候选者。两名审查员独立检查了 85 名患者的术前成像。在 12 个标准化位置测量了关节囊厚度。使用绝对一致的双向随机效应模型计算类内相关系数(ICC)。采用同样的方法,随机抽取了 30 名患者,由一名审查员在冲洗期后进行重复测量。结果使用这些建议的测量方法比较术者间可靠性时,MRI 和 MRA 测量的 ICC 分别为 0.981 和 0.985。使用单个评审员在冲洗期后进行的测量来计算评分者内部可靠性的 ICC 分别为 0.998 和 0.991。在比较同一患者的 MRI 和 MRA 测量值时,对所有汇总测量值进行 t 检验,发现不同测量模式之间无差异(P = .283),按象限细分测量值发现测量值无差异(P > .05),但冠状序列上的囊下侧除外(P = .023)。只有在比较 MRI 和 MRA 在髋关节囊下冠状面上的厚度时才会发现囊厚度的差异,这表明这些成像模式在测量髋关节囊的临床重要方面时具有互换性。
Magnetic Resonance Imaging and Magnetic Resonance Arthrography Are Both Reliable and Similar When Measuring Hip Capsule Thickness in Patients With Femoroacetabular Impingement Syndrome
Purpose
To propose an accurate method of measuring hip capsular thickness in patients with femoroacetabular impingement syndrome and to compare the reliability of these measurements between magnetic resonance imaging (MRI) and magnetic resonance arthrography (MRA).
Methods
A previously established database of patients with femoroacetabular impingement syndrome (FAIS) was used to identify candidates with preoperative MRI or MRA from November 2018 to June 2021. Two reviewers independently examined preoperative imaging for 85 patients. Capsular thickness was measured in 12 standardized locations. Intraclass correlation coefficients (ICCs) were calculated using an absolute-agreement, 2-way random-effects model. Using the same method, 30 patients were randomly selected for repeat measurements by 1 reviewer following a washout period. Ten additional patients with preoperative MRI and MRA of the same hip were identified to compare measurements between modalities using paired samples t test.
Results
ICCs for measurements on MRIs and MRAs using these proposed measurements to compare inter-rater reliability were 0.981 and 0.985. ICCs calculated using measurements by a single reviewer following a washout period for intrarater reliability were 0.998 and 0.991. When comparing MRI and MRA measurements in the same patient, t test for all pooled measurements found no difference between modality (P = .283), and breakdown of measurements by quadrant found no difference in measurements (P > .05), with the exception of the inferior aspect of the capsule on coronal sequences (P = .023).
Conclusions
In patients with FAIS, both MRI and MRA have excellent reliability for quantifying hip capsular thickness. A difference in capsular thickness was found only when comparing MRI and MRA on inferior coronal aspects of the hip capsule, indicating interchangeability of these imaging modalities when measuring the clinically important aspects of the hip capsule.
