Moderate plaque bilaterally with shadowing. in light of the limitations related to shadowing plaque, consider further evaluation with followup ct angi?

Carotid doppler: Your carotid arteries were heavily enough calcified that the calcifications were blocking the ultrasound beam enough that the degree of carotid stenosis cannot be evaluated, thus the suggestion for ct angio. Heavy calcification may also effect the ct angio too. Mra (magnetic resonance angiography) would be another consideration which would not be effected by the calcium.
