Application of MRI in the Evaluation of Low Backache

Abstract

Introduction: Low Backache (LBA) is one of the commonest presenting complaint of patients and it is important to evaluate it. Since degenerative changes and neoplastic lesion present initially with LBA, it is important to differentiate the lesions as degenerative, benign or malignant. Once the lesion is differentiated the patient can be managed appropriately. Aim: The aim of the study is application of MRI in the evaluation of lower backache. Materials and Methods: In this cross-sectional study male and female patients with LBA, between the age group 30 years to 70 years were included. Exclusion criteria were history of trauma, surgery, metallic implants. Study was conducted in the Department of Radio-diagnosis of Sree Mookambika Institute of Medical Sciences for a period of 1 year. In patients who had back pain associated with radiculopathy, spinal stenosis, or another specific spinal cause, Magnetic Resonance Imaging (MRI) proved to be essential. Results: This study shows various conditions which causes LBA and the most common cause of LBA was degenerative disc disease, and the most common position of herniation was posterolateral. Most of the disc herniation was seen at L4-L5 level. Conclusion: MRI is an important tool in diagnosing the pathology causing LBA and in guiding the clinician in further management of the patient.
