Abstract

Introduction: Musculoskeletal infections have been emerging nowadays. Its early diagnosis is warranted as it may lead to disabling sequelae. Recently, the use of diffusion-weighted magnetic resonance imaging (DWMRI) provided additional pulse sequences enabling better diagnosis and needs to be explored for diagnosing musculoskeletal infections. Thus, we conducted this study with an aim to discuss demographic, clinical, and DWMRI findings of the spectrum of musculoskeletal infections, emphasizing the apparent diffusion coefficient (ADC) map for this domain of infections. Methods: A retrospective observational study was carried out in the department of radiodiagnosis of a tertiary care hospital. The study was performed on 50 patients who were suspected cases of musculoskeletal infections. All the patients underwent basic investigations, ultrasound, magnetic resonance imaging, and diffusion-weighted imaging with ADC mapping. The data were entered into MS EXCEL spreadsheet and analysis was done using Statistical Package for Social Sciences (SPSS) version 21.0. Results: Maximum patients were in the age group of 11–20 years (40%) with 58% males and 42% females. Lower limb infections were common, especially the involvement of the hip joint. Pain and swelling were the most common symptoms as seen in 96% and 88% of the patients respectively. DWMRI was able to diagnose and lay down significantly different ADC values for different musculoskeletal infections. The mean ADC values were higher for acute infections and lower for chronic infections. Conclusions: DWMRI holds an important role in the investigation profile for musculoskeletal infections and must be used wherever deemed necessary to avoid unnecessary referrals and treatments.
肌肉骨骼感染患者的人口统计学、临床和扩散加权磁共振成像特征的观察性研究
引言:如今,肌肉骨骼感染已经出现。它的早期诊断是有必要的,因为它可能会导致致残后遗症。最近,扩散加权磁共振成像(DWMRI)的使用提供了额外的脉冲序列,能够更好地进行诊断,并且需要探索用于诊断肌肉骨骼感染。因此,我们进行这项研究的目的是讨论肌肉骨骼感染谱的人口学、临床和DWMRI结果,强调该感染领域的表观扩散系数(ADC)图。方法:在某三甲医院放射诊断科进行回顾性观察研究。这项研究对50名疑似肌肉骨骼感染的患者进行了研究。所有患者均接受了基础检查、超声、磁共振成像和ADC标测的扩散加权成像。将数据输入MS EXCEL电子表格,并使用社会科学统计软件包(SPSS)21.0版进行分析。结果:最多的患者年龄组为11–20岁(40%),其中58%为男性,42%为女性。下肢感染很常见,尤其是髋关节受累。疼痛和肿胀是最常见的症状,分别为96%和88%的患者。DWMRI能够诊断和确定不同肌肉骨骼感染的ADC值。急性感染的平均ADC值较高,慢性感染的平均值较低。结论:DWMRI在肌肉骨骼感染的调查中发挥着重要作用,必须在必要时使用,以避免不必要的转诊和治疗。
