BACKGROUND: This study aimed to evaluate the clinical indications, imaging findings, and structural factors identified on pediatric lumbar MRI, with a specific focus on non-traumatic low back pain and lumbar disc herniation (LDH). MATERIALS AND METHODS: A retrospective review was conducted of 1,253 lumbar MRI examinations performed in pediatric patients aged 0-18 years between November 2022 and March 2024. Clinical indications were documented for all patients. Imaging findings were systematically analyzed in children presenting with non-traumatic low back pain. In patients diagnosed with LDH, the presence of lumbosacral transitional vertebrae (LSTV), spondylolysis, and spondylolisthesis was reassessed. LSTVs were categorized using the Castellvi classification. RESULTS: Low back pain was the most common indication for MRI (n=650, 51.9%). Among these children, 62.3% had normal examinations. Disc protrusion (15.1%), degenerative disc or endplate changes (8.9%), spondylolysis (5.5%), and spondylolisthesis (2.8%) were the most frequent abnormalities. LDH predominantly occurred at the L5-S1 level. LSTVs were identified in 52 patients (8%) with LDH, and higher-grade Castellvi types were significantly associated with LDH (p
