Coronary Angiography:Examines whether the coronary arteries of the heart are narrowed or blocked. It is used to assess the risk of coronary artery disease in patients with diabetes and to determine whether interventional treatment (such as stent implantation) is needed.
Lower Extremity Arteriography:Evaluates blood flow in the lower extremity arteries, diagnoses vascular lesions in diabetic foot, and determines the risk of severe ischemia or necrosis.
Renal Arteriography:Detects renal artery stenosis or abnormal renal blood flow, helping to diagnose diabetic nephropathy or secondary causes of hypertension.
Fundus Fluorescein Angiography (FFA):Observes retinal vascular leakage, microaneurysms, or neovascularization by intravenous injection of sodium fluorescein, and determines the stage of diabetic retinopathy.
