520 a Background In MRI studies of carotid plaques, ultrasound is used to find plaques, which are later imaged using MRI. The performance in plaque detection has not been compared between the modalities. The aim of the current study was to compare the performance of MRI and ultrasound in detecting carotid artery plaques and measuring extent of atherosclerosis. Methods Subjects with at least one plaque (height >= 2.5mm) on ultrasound were imaged using MRI. The number of plaques and their height was measured in both modalities; plaque area and volume were analysed on ultrasound and MRI, respectively. Results Thirty-eight subjects were included. MRI detected plaques in 95% of carotid arteries with a plaque height of 2.5 mm on ultrasound and in all carotid arteries with a plaque exceeding >= 2.5 mm. MRI detected 53% of the plaques with a height below 2.5mm. The plaque height measured with both techniques correlated significantly, 0.59, P<0.0001. Ultrasound-derived plaque height and plaque area correlated similarly to MRI-derived plaque volume, r = 0.52; P<0.0001 and r = 0.47; P = 0.001, respectively. Conclusions We conclude that MRI has a similar sensitivity to ultrasound in finding carotid artery plaques that are 2.5 mm or higher. In smaller plaques, MRI detects fewer plaques. Multiple carotid plaques seen on ultrasound most often are a misinterpretation of the anatomy and correspond to a single plaque. Plaque height on ultrasound is comparable to plaque height on MRI and correlates fairly well with plaque volume on MRI making it an interesting proxy for plaque burden.
