CT assesses plaque composition, but with difficulty

By Eric Barnes

Mean attenuation scores at multidetector-row CT show distinct and reliable differences in the composition of atherosclerotic plaques, far surpassing the capabilities of ultrasound, according to a new study from Massachusetts General Hospital (MGH). But on a 16-slice MDCT scanner, overlapping attenuation values still make it difficult to assign specific plaque composition types to specific tissue samples.
