Overview
MRI may be helpful in the diagnosis of carotid body tumor. Findings on MRI suggestive of/diagnostic of carotid body tumor is salt and pepper appearance on the T2 weighted images. On T1 weighted images, the tumor has the same intensity as the muscle.
MRI
- MRI imaging features of carotid body tumor are characteristics.[1]
- 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.
