VIBE(LAVA-XV/THRIVE/TIGRE) Fat Sat Post Contrast
MRI image appearance
The easiest way to identify T1 VIBE fat-saturated post-gadolinium images is to look for adipose tissues (e.g., subcutaneous fat and fat in bone marrow) and blood vessels in the body (e.g., arteries and veins in the chest, abdomen, upper limbs, and lower limbs). Areas containing adipose tissues appear dark on T1 VIBE fat-saturated post-gadolinium images. Blood vessels and pathologies with high vascularity appear bright on T1 VIBE fat-saturated post-gadolinium images. All other characteristics of the T1 VIBE fat-saturated post-gadolinium images remain the same as the T1 VIBE images.

Pathological appearance
Pathologies with adipose tissue content will appear dark on T1 VIBE fat-saturated post-gadolinium images (e.g., lipoma). Pathologies with hypervascularization will appear bright on T1 VIBE fat-saturated post-gadolinium images (e.g., tumors like hemangioma, lymphangioma, hemangioendothelioma, Kaposi sarcoma, angiosarcoma, hemangioblastoma, etc., and inflammatory processes like discitis, meningitis, synovitis, arthritis, osteomyelitis, etc.). Pathological processes with no vascularity will remain unenhanced (appearing dark on T1 VIBE fat-saturated post-gadolinium images).
