Abstract Objectives To explore the features of high-intensity zone (HIZ) in anterior annulus fibrosus and assess the association of anterior HIZ with low back pain (LBP). Design, Setting, and Subjects A retrospective study of 5,940 discs in 1,188 individuals was conducted. Methods Subjects’ information and LBP symptoms confirmed by an orthopedic surgeon were acquired from the medical record. Magnetic resonance (MR) image reading and analysis were performed by two experienced blinded radiologists. Results Two hundred eighty individuals exhibited 355 anterior HIZs in 355 discs. The prevalence was 23.57%; 88.45% were located in the inferior part of the annulus fibrosus. It frequently occurred in the middle and upper segments of lumbar spine, especially at L3/4 (45.63%). Of the 355 anterior HIZs, only 79 (22.25%) were consecutive-slides HIZ. Round type (63.38%) was the most common shape of anterior HIZs. The highest prevalence was found in individuals aged 60–69 years. LBP was confirmed in 141 anterior-HIZ individuals. The incidence of LBP in anterior-HIZ individuals was significantly higher than in non-HIZ subjects (50.36% vs 35.24%, χ2 = 18.314, P < 0.001). Conclusions Anterior HIZ is a lower-prevalence, age-related sign on lumbar MR images. The spatial distribution of anterior HIZ can be distinguished from posterior HIZ. The number of consecutive anterior HIZ slides might suggest fewer Dallas grade 4 anterior annular disruptions in this sample. Anterior HIZ was correlated with LBP.

Purpose. To assess the correlation between low back pain and a high-intensity zone (HIZ) of the lumbar disc in Indian patients. Methods. 200 patients with low back and/or leg pain underwent magnetic resonance imaging of the lumbosacral spine. The location and severity of pain and disability were assessed using the pain drawing, visual analogue scale, and Oswestry Disability Index, respectively. The inter-observer reliability was assessed using the kappa statistic. Results. The prevalence of an HIZ was 13% and 17% according to observers A and B, respectively. The inter-observer reliability was fair (κ=0.64, p<0.005). The presence of an HIZ did not correlate with low back pain according to the pain drawing, visual analogue scale, and Oswestry Disability Index. According to the pain drawing data, the sensitivity, specificity, and positive predictive values of an HIZ to low back pain were 11%, 82%, and 62%, respectively. Conclusion. The presence of an HIZ is not diagnostic of a disrupted and painful disc, and should be interpreted together with other prevailing symptoms and clinical findings.
