What is a typical component of a brain MRI report's lesion description?

• A. Sequences performed and protocol details
• B. Seizure history
• C. Lesion characteristics and diffusion restriction
• D. The radiologist's lunch choice

Answer: (B)

Lesion description in a brain MRI centers on detailing the lesion’s imaging features: its location, size, margins, signal characteristics on different sequences, enhancement if present, and, importantly, whether diffusion is restricted. Diffusion restriction on DWI/ADC helps differentiate acute or highly cellular processes (like acute infarct, abscess, or certain tumors) from non-restrictive lesions, guiding the differential and management. Sequences performed and protocol details belong in the technique section of the report, not in the lesion description, and seizure history is clinical information that may accompany the report but isn’t part of the imaging description of the lesion itself. The radiologist’s lunch is obviously irrelevant.
