A 3 T MRI of the brain was conducted at baseline (3\u201317 days after trauma) and at 3 months after patients were diagnosed with mTBI according to the World Health Organization criteria. The TMBs were evaluated, counted, and assigned locations by a neuroradiologist according to the Common Data Elements for Neuroimaging of Traumatic Brain Injury (CDE-TBI). At baseline, 22 out of 113 (19%) patients had at least one TMB. After initial imaging, 22 patients dropped out, resulting in 88 patients, of whom 21 (24%) had at least one TMB. Across these patients, a total of 129 TMB lesions were detected at baseline, all of which were visible at follow-up imaging. No new TMB lesions that were not detected at baseline were seen at follow-up imaging. The most common CDE-TBI regions for TMBs were the frontal (77\/129, 60%), temporal (33\/129, 26%), and parietal (8\/129, 6%) subcortical white matter. For each patient, the TMB lesions were located in one region in 10% (9\/88), two regions in 3% (3\/88), three regions in 3% (3\/88), and four or more regions in 7% (6\/88) of the CDE-TBI regions. Twenty-five out of 88 (28%) patients also had other trauma-related intracranial abnormalities: 10\/25 (40%) of which had at least one TMB, which was true only for 17% (11\/63) for those without (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    &lt; 0.05). In conclusion, initial TMBs can still be reliably found with conventional MRI after 3 months in patients with mTBI: delayed imaging does not necessarily compromise the detection of these lesions. Other radiological abnormalities are linked with higher prevalence of TMBs, possibly suggesting increased injury burden within the mTBI population.\n
