Carotid Arterial Stenosis: Evaluation at CT Angiography with the Volume-rendering Technique

Abstract: These results indicate that VRT CT angiography is as accurate as SSD CT angiography in the evaluation of carotid arterial bifurcations.

“…CT has been found in multiple trials to be accurate in the diagnosis of carotid artery stenosis but can lead to miscategorization of the degree of stenosis, especially if not performed and evaluated properly or if the plaques causing stenosis are heavily calcified [8][9][10][11][12][13]. However, our groups for classification of the percentage luminal stenosis for total vessel and individual vessel scores were relatively broad, making error in categorization less likely.…”

“…This may partly be because of the predominant use of sonography and MR angiography in imaging studies involving the neck vasculature, but these techniques are significantly limited in the evaluation of calcium. MDCT angiography is a robust technique for assessing calcification and can potentially depict and allow quantification of load in the carotid arteries in a manner similar to coronary artery scoring, while being highly accurate for measuring luminal stenosis [8][9][10][11][12][13].…”

“…5,6 By using MDCT, it is possible to employ different postprocessing techniques in addition to source axial images. MIP, MPR, CPR, and VR 7,8 are currently the most frequently used. A deeper knowledge of the potential of postprocessing techniques and their application will allow optimization of the MDCTA dataset.…”

“…Compared to ultrasound, CTA and MRA are markedly less dependent on the experience of the investigator. Among the reconstruction techniques, the degree of stenosis as well as the extent of calcifications best delineated by VR [5]. CTA is more precise than MRA in delineating the residual lumen in vessels with high-degree stenosis.…”
