Development of diagnostic methods of renal artery stenosis

With the incessant development of medical technology, the methods of screening and diagnosis for renal artery stenosis are constantly updated.In general, the most widely used method is color doppler ultrasound, and then the multi-slice spiral CT angiography, MRI and the radionuclide imaging. Renal artery angiography is not only one kind of reliable diagnostic technique, but also an absolutely necessary means to guide the interventional treatment.This review mainly describes the above methods from diagnosis standards, specificity, sensitivity, advantages and disadvantages.Furthermore, it also offers some forward-looking visions from the development of the radionuclide imaging by SPECT.
