The aim of this study is to evaluate the MDCT angiography as a recent non invasive technique for investigating aorto-iliac arterial disease as compared to CCD and DSA.
This study included 16 patients (12 males & 4 females) with an age range of 33-75 years. All of these patients underwent MDCT angiography and CCD. Only 13 patients underwent DSA. The arterial tree of the lower limbs was divided into 31 arterial segments. Each segment was evaluated and given a grade from 0 to 4 according to its appearance in the three modalities.
There was a 98.7 % agreement between the findings of DSA and MDCT angiography. While agreement between DSA and CCD was 96.1 % .
Considering conventional angiography as the gold standard, MDCT angiography shows higher sensitivity (98.7 % ) than color coded Doppler ultrasonography (96.2 % ) in the assessment of aorto-iliac arterial disease.
