MRI structural patterns and scoring for dementia subtypes

Structured MRI review of atrophy patterns aids differential diagnosis of common dementias, including Alzheimer's disease, frontotemporal lobar degeneration, and vascular cognitive impairment. Specific regional scores and visual rating scales are presented for clinical use.

• Educational review from The Radiology Assistant detailing a practical, pattern-based approach to MRI interpretation in dementia.
• Covers medial temporal lobe atrophy (MTA) score, global cortical atrophy (GCA) scale, and Fazekas scale for white matter lesions, with visual examples.
• Intended as a teaching resource for radiologists and trainees to improve systematic reporting; not a primary research study with outcomes data.
