Abstract

Purpose: To compare easy-to-perform three-dimensional power Doppler ultrasound (3D PDUS) to color Doppler ultrasound (CDUS) and digital subtraction angiography (DSA) in the assessment of internal carotid artery (ICA) stenoses in patients with severe atherosclerosis.

Methods: 26 ICA's (7 without stenosis, 4 low-, 4 middle-, and 11 high-grade stenoses) in 13 patients were examined with DSA, CDUS, and 3D PDUS. CDUS and 3D PDUS were performed with a 7.5 MHz standard transducer and a Sonoline Elegra ultrasound machine. The three methods were performed and interpreted by different persons who were not aware of the diagnoses.

Results: Regarding the degree of stenosis correlations between DSA and 3D PDUS were r = 0.98 (p < 0.001), between DSA and CDUS r = 0.97 (p < 0.001), and between CDUS and 3D PDUS r = 0.95 (p < 0.001). Sensitivity and specificity regarding the detection of a high-degree stenosis was 90% and 100% for 3D PDUS, and 100% and 93.3% for CDUS.

Conclusion: Even in cases with severe atherosclerosis, both sonographic methods reveal similar results comparable to DSA. 3D PDUS does not result in a diagnostic improvement on CDUS, however, it does give the new opportunity for complete data storage, reconstruction, and survey presentations.
