摘要
背景：膝炎相关关节炎（ERA）是青少年特发性关节炎（JIA）的一个亚型，其特征是骶髂关节（SI）频繁受累。目的：本研究的目的是评估零回波时间（ZTE）磁共振成像（MRI）识别ERA患者结构性病变的有效性。常规的MRI脉冲序列往往难以充分显示骨化和钙化组织。材料和方法：所有MRI检查均使用1.5 T (T)扫描仪进行。MRI方案包括标准序列，如脂肪抑制轴向t2加权、轴向t1加权、冠状短tau反转恢复（STIR）和轴向t2加权序列。除常规MRI外，采用中兴通讯序列。以低剂量CT作为参考标准，使用640多层CT设备进行。结构性病变，包括糜烂、硬化症和关节间隙的改变，在不同的成像方式下进行比较。结果：共纳入20例患者（12例男孩，8例女孩），诊断时的中位年龄为14岁。ZTE-MRI检测糜烂的敏感性与低剂量CT相似（7 vs 8, P = 0.707）。低剂量CT与ZTE-MRI的类间相关系数（ICC）为0.993 (P)。结论：零回波时间成像可提供与低剂量CT相当的骶髂关节显像，从而提高对骶髂关节细微糜烂和硬化的检测。
Assessment of sacroiliitis using zero echo time magnetic resonance imaging: a comprehensive evaluation.
Background: Enthesitis-related arthritis (ERA), a subset of juvenile idiopathic arthritis (JIA), is characterized by frequent involvement of the sacroiliac (SI) joints.
Objective: The aim of this study was to assess the effectiveness of zero echo time (ZTE) magnetic resonance imaging (MRI) in identifying structural lesions in patients with ERA. Conventional MRI pulse sequences often struggle to adequately visualize osseous and calcified tissues.
Materials and methods: All MRI examinations were conducted using a 1.5-T (T) scanner. The MRI protocol included standard sequences such as fat-suppressed axial T2-weighted, axial T1-weighted, coronal short tau inversion recovery (STIR), and axial T2-weighted sequences. In addition to conventional MRI, a ZTE sequence was employed. Low-dose computed tomography (CT) served as the reference standard and was performed using a 640-multislice CT device. Structural lesions, including erosions, sclerosis, and changes in joint space, were compared between imaging modalities.
Results: A total of 20 patients were included in the study (12 boys, 8 girls), with a median age at diagnosis of 14 years. ZTE-MRI demonstrated similar sensitivity to low-dose CT in detecting erosion (7 vs 8, P = 0.707). The interclass correlation coefficient (ICC) between low-dose CT and ZTE-MRI was 0.993 (P < 0.001), indicating excellent agreement. Moreover, ZTE-MRI showed strong agreement with low-dose CT in detecting sclerosis (ICC = 0.954, P < 0.001) and changes in joint space (ICC = 0.998, P < 0.001).
Conclusions: Zero echo time imaging shows promise in providing sacroiliac joint visualization comparable to low-dose CT scans, thereby improving the detection of subtle erosion and sclerosis in these joints.
期刊介绍：
Official Journal of the European Society of Pediatric Radiology, the Society for Pediatric Radiology and the Asian and Oceanic Society for Pediatric Radiology
Pediatric Radiology informs its readers of new findings and progress in all areas of pediatric imaging and in related fields. This is achieved by a blend of original papers, complemented by reviews that set out the present state of knowledge in a particular area of the specialty or summarize specific topics in which discussion has led to clear conclusions. Advances in technology, methodology, apparatus and auxiliary equipment are presented, and modifications of standard techniques are described.
Manuscripts submitted for publication must contain a statement to the effect that all human studies have been reviewed by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in an appropriate version of the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted.
