OR

There are no MRI findings associated with [disease name]. However, an MRI may be helpful in the diagnosis of complications of [disease name], which include [complication 1], [complication 2], and [complication 3].

MRI

• MRI imaging features of carotid body tumor are characteristics.
• Due to the vascular nature of the tumor, contrast administration results in its enhancement.
• The classic finding is a salt and pepper appearance on T2 weighted images.
  • The salt is for the foci of hemorrhage resulting in high signal
  • The pepper is for the low signal flow voids
• On T1 weighted images, the carotid body tumor has the same intensity as the muscle.
• On T2 weighted images, it tends to appear hyperintense.
