Study Of Lower Limbs Arteries In Diabetic Patients Using CT Angiograghy

Abstract

This study was a descriptive study type designed to study the efficacy of multi slice computerized tomography (MSCT) in imaging the lower limb arterial tree to diagnose the ischemic and other vascular disease in diabetes patient, the data was collected from radiology department of Modern Medical Center , ALMoalem Medical City , the study was carried out in the (Sudan–Khartoum state).The study duration from November 2017 to May 2018: the patient population consists of 20 females and 30 males with the mean of the ages is 65y and the male percent 60% was more than females 40%. In the study the disease prolongation categorized as (>1y, 1-5y, and<5yandpercent7.5%, 85.0%, 7.5%). And the common finding was Atherosclerosis, total stenosis; occlusion and collateral.50 diabetes patient s have undergone CT angiography of the lower limb by Multi detector (GE Optima 16 CT Scanner). with symptoms of peripheral vascular disease, All patients were scanned in the supine position with A detector configuration of 16 x .625mm is used, acquisition timing for optimum opacity is achieved by using automatic bolus tracking (Smart prep technology, GE Medical Systems), with 120-130cc of low osmolar non-ionic contrast medium (Omni opaque 300) with a flow rate between4-4.5 cc/sec, via a pressure injector, by using one box of the scan protocol. Axial images were then reconstructed with 50 percent overlap and then transferred to a dedicated workstation for 3-D reconstruction and analysis; in maximum intensity projection (MIP), volume rendered (VR) and (MPR). Our initial experience CT angiography with multi slice has clearly demonstrate efficacy as a promising new, fast, accurate, safe and non- invasive imaging modality of choice in cases of diabetes peripheral vascular diseases for diagnosis, for grading, for potential usefulness and as a treatment planning tool and are the key to communicating the findings to the treating physician, decisions making (surgical versus trans-luminal revascularization, or, intervention, conservative treatment.
