Generate a structured 6-section MRI report using PASSIVE VOICE and PRESENT TENSE. Minimum 700 words total — be thorough.\n\n=== MANDATORY RULES ===\nRULE 1 — EXACT NUMBERS: Copy ALL volume values EXACTLY. Never round or omit.\nRULE 2 — CHANNELS: RED=T1c(ET), GREEN=FLAIR(ED), BLUE=T2(NCR).\nRULE 3 — MIDLINE: Always {midline_est}mm (falx displacement).
