T2 inversion sequence is used in routine radiology practice mainly to heighten contrast resolution within the region to be studied but no evidence exists in current literature to assess it's true efficacy for lumbar disc degeneration. The objective of this study was to analyse T2 inversion and evaluate it's efficacy in assessment of lumbar disc pathology,.
This retrospective single-centre study included 50 randomly selected patients presenting with back pain and radiculopathy. T2 inversion sequence was obtained in both axial and sagittal planes in addition to routine sequences. All the Magnetic Resonance Imaging (MRI) procedures were performed on 3T. One senior Musculoskeletal (MSK) radiologist, 2 general radiologists and a spinal surgeon blinded to final results reviewed images for the various disc pathologies individually analysing conventional and T2 inversion images. Data was analysed using Fischer's test and Chi test with a p value of <0.05 considered as significant.
Fifty randomly selected patients (mean age was 47.3 years(range 35-55 years) with back pain and radicular symptoms were included. The spectrum of disc pathologies included protrusions, annular fissures, discal cysts and calcified discs. Based on the above findings, T2 inversion sequence is not proved to be an alternative imaging sequence to routine MR imaging sequences for the depiction of various disc pathologies.
T2 inversion sequence does not increase the depiction of various lumbar disc pathologies in comparison with conventional sequences when used by experienced MSK radiologists. It may highlight abnormalities better for relatively inexperienced readers such as general radiologists and spinal surgeons.
T2反相位序列在常规放射学实践中主要用于提高待研究区域内的对比分辨率,但目前文献中尚无证据评估其对腰椎间盘退变的真实疗效。本研究的目的是分析T2反相位序列并评估其在腰椎间盘病变评估中的疗效。
这项回顾性单中心研究纳入了50例随机选择的有背痛和神经根病症状的患者。除常规序列外,还在轴向和矢状面获取了T2反相位序列。所有磁共振成像(MRI)检查均在3T设备上进行。一名资深肌肉骨骼(MSK)放射科医生、两名普通放射科医生和一名脊柱外科医生在不知最终结果的情况下分别对各种椎间盘病变的图像进行回顾,分析传统图像和T2反相位图像。采用Fischer检验和卡方检验分析数据,p值<0.05被认为具有统计学意义。
纳入了50例随机选择的有背痛和神经根症状的患者(平均年龄47.3岁,范围35 - 55岁)。椎间盘病变谱包括椎间盘突出、纤维环破裂、椎间盘囊肿和钙化椎间盘。基于上述发现,对于各种椎间盘病变的显示,T2反相位序列未被证明是常规MR成像序列的替代成像序列。
对于经验丰富的MSK放射科医生而言,与传统序列相比,T2反相位序列并不能增加对各种腰椎间盘病变的显示。对于普通放射科医生和脊柱外科医生等经验相对不足的阅片者,它可能能更好地突出异常表现。
