Abstract

Background The aim of the study was to prospectively evaluate the diagnostic value of MRA of the renal arteries compared with renal duplex scanning in patients with clinical suspicion of renovascular disease using conventional angiography as a standard reference.
Material and methods The study included 50 patients (33 women, 17 men, mean age: 49 yrs) with clinical suspicion of renovascular disease in whom MRA and duplex doppler were performed. All subjects underwent conventional angiography to verify the results of non-invasive methods. MRA examinations were performed with the use of of magnetic resonance system 1.5 T MAGNETOM SP 63 (Siemens) with the application of the whole-body coil. For evaluation of renal arteries 3D TOF technique has been used. Doppler Duplex (ATL 3000 HDI) evaluation was done with the ATL 3000 HDI.
Results Our results indicate that sensitivity, specificity and accuracy for MRA was 98,1%, 88,6% and 93,9% respectively and for duplex doppler 87,7%, 90,6% and 87,8% respectively. The differences in sensitivity, specificity and accuracy between two methods were statistically significant.
Conclusion Our results indicate that MRA has high sensitivity and specificity for the detection of renal artery stenosis and are comparable with the data published so far. Our study demonstrate that this method has the potential usefulness for diagnosing patients suspected for renovascular disease.
