MRI VIBE(LAVA-XV/THRIVE/TIGRE) Post Contrast

MRI image appearance VIBE Post Contrast

The easiest way to identify T1 VIBE post-gadolinium images is to look for blood vessels in the body (e.g., arteries and veins in the brain, neck, chest, abdomen, upper limbs, and lower limbs). Blood vessels and pathologies with high vascularity appear bright in T1 VIBE post-gadolinium images. All the other characteristics of the T1 VIBE post-gadolinium images remain the same as the T1 VIBE images.

Tissues and their T1 VIBE post gadolinium appearance

Use

Pathological appearance

Pathologies with hypervascularization will appear bright on T1 VIBE post-contrast gadolinium images. Examples of such pathologies include tumors like hemangioma, lymphangioma, hemangioendothelioma, Kaposi’s sarcoma, angiosarcoma, hemangioblastoma, as well as inflammatory processes like discitis, meningitis, synovitis, arthritis, and osteomyelitis. Pathological processes with no vascularity will remain unenhanced, appearing dark on T1 VIBE post-contrast gadolinium images.
