Outline
Renal vascular hypertension is in a continuous rising stage, which is common in middle-aged and elderly patients. Renal artery stenosis is the main cause of its disease. If it is not treated as soon as possible, it is prone to renal function injury, and even renal failure may occur. Timely assessment of renal artery stenosis is helpful for pre-treatment and prognosis evaluation of renovascular hypertension. There are many ways to evaluate renal artery imaging, such as ultrasound, digital subtraction angiography, CT angiography, contrast enhanced MR angiography, non contrast enhanced MR angiography, etc. Non contrast enhanced MR angiography has the advantages of multi parameter, multi angle, non-invasive, non radiation, no contrast injury, high-resolution imaging and so on. Compared with the commonly used methods of renal artery imaging evaluation, such as ultrasound and CT angiography, this article focuses on the research progress of different non contrast enhanced MR angiography techniques in the evaluation of renal artery stenosis.
