Whiteout sign on dSIR MRI: A case series highlighting symptom-associated white matter changes not observed on standard T2-FLAIR.

Key Points

• The aim is to explore how dSIR MRI can indicate brain changes associated with mild traumatic brain injury.
• Analysis of MRI scans focusing on dSIR artifacts
• Identification of symptom-associated white matter changes
• Comparison with standard T2-FLAIR imaging
• dSIR MRI revealed symptom-associated white matter changes not detected by standard T2-FLAIR
• Indications suggest dSIR could serve as a useful imaging marker
• Further studies needed to assess dSIR's sensitivity and specificity in clinical settings
