dcterms:description
The aim of our study was to evaluate duplex ultrasonography (DUS) and magnetic resonance angiography (MRA) in detection of haemodynamically significant renal artery stenosis (RAS). The study included patients with high clinical suspicion of renovascular hypertension (RVH). The imaging of renal arteries was performed by DUD. MRA and digital subtraction angiography (DSA). Significant RAS was defined as maximum systolic velocity_ 180 cm/sec (DUS) or as 60% reduction of the endoluminal arterial diameter (MRA.DSA). The results of DUS and MRA were assessed in respect to the results of DSA. Arterial supply of 186 kidneys in 94 patients was evaluated. DSA revealed significant RAS in 61 kidneys evaluated. DUS was not able to examine arterial supply in 18 kidneys of 13 patients. In the detection of significant RAS.DUS was characterized by sensitivity and specificity of 85% and 84%. MRA achieved satisfactory imaging quality in all but one kidney evaluated. The sensitivity and specificity of MRA in the detection of significant RAS was 93%, respectively. In patients with high clinical probability of RVH. MRA proved to be more reliable and superior in both sensitivity and specificity to DUS in the detection of significant RAS.
