Technical Considerations

Several studies have been published on the usefulness of MR angiography of carotid bifurcations and epiaortic vessels. Almost all of them were carried out with the Time-of-Flight technique, most of them using the 2D acquisition modality. These studies claim a good overall sensitivity and specificity by comparison to digital subtraction angiography, Doppler ultrasound or both in the demonstration of carotid clinically relevant stenosis, with a slight overestimation of the degree of stenosis, especially in the moderate and severe groups. Unlike Doppler ultrasound, distal cervical and proximal intracranial arteries can be relatively well evaluated by MR angiography. Nevertheless, MR angiography also has limitations, among the best known, difficult visualization of the origin of neck arteries, inaccurate depiction of vessel morphology in case of complex flow and unreliable quantification of the degree of stenosis have to be mentioned. To get the most of the diagnostic potential of MR angiography, imaging strategies and technical considerations have to be adapted to the morphological and hemodynamic particularities of the different segments of the supraaortic arterial structures.

Digital subtraction angiography (DSA) is the gold standard investigation to assess the extracranial stenosis of carotid vessels. But this is an invasive diagnostic tool. So it is still a controversial issue whether duplex ultrasound is an alternative to DSA for measurement of stenosis of carotid vessels. This prospective crossectional observational study was conducted in the department of Neurology, BSMMU, Dhaka from May 2012 to April 2013 to assess the diagnostic accuracy of duplex ultrasound and its potential to replace DSA before performing carotid endarterectomy (CEA) and carotid stenting. Total of 38 patients, 33 patients of nondisabling ischaemic stroke and 5 patients with history of TIAs whose extracranial carotid stenosis was >50% on duplex ultrasound were selected for DSA. DSA was done on these vessels and stenosis was measured using NASCET criteria. Results of USD and DSA were compared to determine the sensitivity, specificity and accuracy of duplex ultrasound (USD). At 70% stenosis of right internal carotid artery and left internal carotid artery the sensitivity, specificity and accuracy were 93.8%, 63.7%, 89.5% and 93.3%, 75%, 89.5% respectively. This level of diagnostic efficiency of USD is less than that of DSA of carotid arteries. It was found in this study that, USD underestimates or overestimates the degree of carotid stenosis. DSA was safe and effective in determining stenosis in this study & there was no 67 complication. So before taking any decision for carotid endarterectomy or carotid artery stenting, digital subtraction angiography of carotid vessels should be done.

Intravenous Digital Subtraction Angiography

✓ Seventy-four consecutive patients who had undergone carotid endarterectomy procedures were examined with intravenous digital subtraction angiography (IV-DSA) and duplex ultrasonography (DUS) at intervals ranging from 1 to 14 months postoperatively. Ninety-one percent of the DUS and 74% of the DSA images were of diagnostic quality. The two modalities agreed in the assessment of the endarterectomy appearance in 84% of the arteries, with 85% showing no evidence of significant residual disease. There were no arteries with severe restenosis or complete occlusion. In the 10 vessels in which the two modalities disagreed in disease assessment, the IV-DSA images were often degraded by artifact or vessel overlap leading to underestimation of disease. The authors conclude that DUS is the examination of choice for routine follow-up studies of carotid endarterectomy.
