title: [Cardiovascular whole body MRI with parallel imaging].
abstract: OBJECTIVE
  To create a whole-body cardiovascular MRI protocol with parallel imaging (iPAT).
  
  
  METHODS
  Twenty two persons participated in the whole body scan. Due to iPAT high resolution imaging of the heart could be performed. 3D contrast enhanced MR angiography (3D-CE-MRA) took only 62 s to cover the whole body at a spatial resolution of less than 1.4x1.0x1.5mm(3). Scan time for HASTE lung imaging could be reduced by the factor of 2 while maintaining the signal to noise ratio (SNR). Image quality was rated by 2 radiologists blinded to each other.
  
  
  RESULTS
  Mean scan time was 104 min on the standard system and less than 80 min on the new system. 75% of all MRA segments were rated good in terms of vessel conspicuity, more than 80% had no venous overlay. One case of distal occlusion of the anterior tibial artery and two cases of myocardial infarction were detected.
  
  
  CONCLUSIONS
  Parallel imaging offers the possibility of fast whole body imaging. A combination of morphologic and functional imaging can be performed within less than 80 min.
