Background Fat quantification methods in magnetic resonance imaging (MRI) have been studied to differentiate bone marrow pathologies in adult patients; however, scarce literature is available in pediatric patients.Purpose To evaluate the efficacy of the T1 signal intensity value (T1-SIV), out-of-phase/in-phase signal ratio (OP/IP SR), and fat fraction (FF) to differentiate between normal, benign, and malignant pathological processes.Material and Methods A total of 48 pediatric patients with lumbar and pelvic MRI were classified into three groups according to bone marrow pathology (group 1, normal; group 2, benign pathology/reconversion; group 3, malignant). The efficacy of T1-SIV, OP/IP SR, and FF values in differentiating these pathologies was evaluated using Kruskal-Wallis or analysis of variance and followed by Bonferroni or Dunn-Bonferroni tests. Cutoff values for malignant infiltration were defined using ROC analysis.Results Although these values were significantly different in all three groups (P = 0.001-0.008), this difference was not sufficient to discriminate between all groups. Subgroup analyses showed significant differences in T1-SIV between groups 1-3, in OP/IP SR between groups 1-3, 2-3, and 1-2, in FF between groups 1-2 and 1-3 in various regions (P = 0.001-0.049). Cutoff values had a sensitivity and specificity of 90%-100% for OP/IP SR and FF.Conclusion T1-SIV, OP/IP SR, and FF may potentially distinguish normal from pathological bone marrow. OP/IP SR and FF values detected malignant infiltration with high sensitivity and specificity in this study. However, only OP/IP SR may significantly differentiate benign and malignant bone marrow pathologies which needs to be confirmed in the future study with a larger patient population.

OBJECTIVE: This study aimed to determine the computed tomography findings associated with very recent catastrophic 2023 Turkey-Syria earthquake-related injuries and their anatomotopographic distribution in the adult population.METHODS: The incorporated computed tomography scans of 768 adult cases who had been admitted to the hospital and had undergone computed tomography imaging after these tragic disasters had been examined on the Teleradiology Reporting System of the Turkish Ministry of Health. To this end, the injuries were classified into six categories: head, thoracic, spinal, pelvic, extremity, and abdominal injury, with three age groups (18-34, 35-64, and 365 years) and four different imaging intervals (<24, 24-48, 49-72, and >72 h).RESULTS: This study incorporated 316 (41.1%) cases on the first day, 57 (7.5%) on the second day, 219 (28.5%) on the third day, and 176 (22.9%) on the fourth day after the earthquake or later. Of the 768 cases, 109 (14.2%) had a head injury, 100 (13.0%) had a thoracic injury, 99 (12.9%) had a spinal injury, 51 (6.6%) had a pelvic injury, 41 (5.4%) had an extremity injury, and 11 (1.4%) had an abdominal injury.CONCLUSION: In these regrettable earthquake disasters, we determined a high ratio of head injuries, which was closely followed by thoracic and spinal injuries, in our preliminary outcomes for the pediatric population, Part I. The frequency of abdominal injuries was low among individuals who experienced the earthquake. Last but not least, we have noticed a higher likelihood of spinal injury in individuals older than 65 years in the studied population.
