Dual-source CT Angiography Diagnosis of Carotid Atherosclerosis in Ischemic Stroke Patients with Diabetes Mellitus / 中国医学影像学杂志

ABSTRACT

PurposeTo evaluate the value of dual-source CT angiography (DSCTA) in the diagnosis of carotid atherosclerosis, and to explore the relationship between carotid atherosclerosis and diabetes mellitus (DM).Materials and Methods 145 patients with ischemic stroke were divided into DM group (n=80) and non-DM group (n=65). All patients underwent DSCTA. The location and characteristic of carotid atherosclerosis were analyzed using curve planE reconstruction (CPR), maximum intensity projection (MIP), multi-plane reformation (MPR) and volume rendering (VR). The differences between two groups were analyzed.Results Compared with non-DM group, the body mass index and high blood cholesterol were higher in DM group (t=6.197,P0.05). Carotid atherosclerosis was more common in carotid bifurcation and carotid artery siphon.Conclusion DSCTA can demonstrate the location and characteristics of carotid atherosclerosis in ischemic stroke patients with diabetes mellitus. Diabetes is a risk factor for the formation of carotid atherosclerosis, especially vulnerable plaques.
