AB  - PURPOSE: To evaluate the value of vascular ultrasound determining the 
      pre-interventional degree of distal stenosis in the extracranial internal carotid 
      artery (ICA) by means of color-coded duplex sonography (CCDS) and B-flow. 
      Comparison with contrast-enhanced 64-line CT angiography (CTA), contrast-enhanced 
      MRA (ceMRA) and digital subtraction angiography (DSA). MATERIALS AND METHODS: 
      Complementary diagnostics and evaluation of the stenosis by means of CCDS, 
      B-flow, CTA, ceMRA and DSA were performed prior to percutaneous stent-assisted 
      PTA in 21 symptomatic ICA stenosis. Ultrasound diagnostics were carried out with 
      high-resolution linear transducers (5-10 MHz and 9-14 MHz). A bolus-triggered 
      contrast-enhanced multislice CTA (collimation 64x0.5 mm) and a ceMRA (1.5 Tesla) 
      as well as selective DSA were performed in every patient. The degree of distal 
      stenosis was established in accordance to NASCET criteria by averaging 5 single 
      measurements per modality and patient. The source images as well as MPR and MIP 
      reconstructions were evaluated in the CTA and ceMRA. Hemodynamic flow parameters 
      were determined with CCDS and B-flow. The images were assessed by two experienced 
      readers in consensus. RESULTS: The extent of stenosis ranged from 45 to 95%, 
      averaging 73% (+/-13%). There was a high degree of agreement between the B-flow 
      results (r=0.938), the CCDS (r=0.852), the measurements from the source data of 
      the ceMRA (r=0.9117) and reconstructions of the CTA (r=0.8598) compared to 
      quantitative DSA as a reference technique. CONCLUSION: Compared to selective DSA, 
      vascular ultrasound in combination with CTA and ceMRA increase the reliability of 
      the diagnostic quantification of ICA stenosis.
