MRI image appearance

The easiest way to identify T1 FLASH fat-saturated images is to look for adipose tissues in the body, such as subcutaneous fat and fat in the bone marrow. Areas containing adipose tissues appear dark on T1 FLASH fat-saturated images. All other characteristics of the T1 VIBE fat-saturated images remain the same as the T1 FLASH images.
