Magnetic resonance imaging is the standard imaging modality for detecting disc pathology due to its advantage of lack of radiation, multiplanar imaging capability, excellent spinal soft-tissue contrast, and precise localization of intervertebral discs changes. The aim of the study is to find out the prevalence of lumbar disc degenerative disorder among patients undergoing magnetic resonance imaging in a tertiary care hospital.
A descriptive cross-sectional study was conducted in the Department of Radiodiagnosis and Interventional Radiology of a tertiary care centre among patients with complaints of low back pain from 24th May, 2021 to 31st December, 2021 in a tertiary care hospital. Ethical clearance was taken from the Institutional Review Committee (Reference number: 134/2077-78). A sample size of 899 was taken and convenience sampling was done. Collected data were entered and analyzed on Statistical Package for the Social Sciences version 22.0. Point estimate at 95% Confidence Interval was calculated along with frequency and percentage for binary data and mean with standard deviation for continuous data.
Among 899 patients undergoing magnetic resonance imaging, the prevalence of lumbar disc degenerative disorder was found to be 155 (17.24%) (14.77-19.70 at 95% Confidence Interval).
The prevalence of lumbar disc degenerative disorder among patients undergoing magnetic resonance in our study was lower when compared to other similar studies conducted in similar settings.

磁共振成像由于其无辐射、多平面成像能力、出色的脊柱软组织对比度以及对椎间盘变化的精确定位等优势，是检测椎间盘病变的标准成像方式。本研究旨在探讨在一家三级医院进行磁共振成像的患者中腰椎间盘退行性疾病的患病率。
这是一项在一家三级医院的放射诊断和介入放射学系进行的描述性横断面研究，纳入了 2021 年 5 月 24 日至 12 月 31 日期间因腰痛就诊的患者。该研究获得了机构审查委员会的伦理批准（编号：134/2077-78）。我们抽取了 899 名患者作为样本，并采用方便抽样法。收集的数据在社会科学统计软件包 22.0 上进行录入和分析。计算了 95%置信区间的点估计值，以及二分类数据的频率和百分比、连续数据的均值和标准差。
在 899 名接受磁共振成像的患者中，腰椎间盘退行性疾病的患病率为 155 例（17.24%）（95%置信区间为 14.77%-19.70%）。
与在类似环境中进行的其他类似研究相比，本研究中接受磁共振成像的患者的腰椎间盘退行性疾病患病率较低。
