Remembering T1-Weighted MRI: Fat Bright, Fluid Dark

T1-weighted MRI: fat is bright, fluid is dark, and protein-rich material or hemorrhage can also appear bright. Understanding why tissues appear as they do makes interpretation easier.

• In T1-weighted images, fat appears bright and simple fluid appears dark.
• Proteinaceous or hemorrhagic material can also be bright on T1 due to its paramagnetic effects.
• Recognizing these basic signal patterns helps build a systematic approach to MRI interpretation.
