AB  - PURPOSE: To evaluate the effectiveness of three-dimensional (3D) dynamic 
      time-resolved contrast-enhanced MRA (TR-CE-MRA) using a combination of a parallel 
      imaging technique (ASSET: array spatial sensitivity encoding technique) and a 
      time-resolved method (TRICKS: time-resolved imaging of contrast kinetics) and to 
      compare it with 3D dynamic TR-CE-MRA using ASSET alone in the assessment of 
      intracranial arteriovenous malformations (AVMs). MATERIALS AND METHODS: Twenty 
      consecutive patients with angiographically confirmed AVMs were investigated using 
      both 3D dynamic TR-CE-MRA techniques. Examinations were compared with respect to 
      image quality, spatial resolution, number and type of feeders and drainers, nidus 
      size, presence of early venous filling and temporal resolution. Digital 
      subtraction angiography was used as standard of reference. RESULTS: The higher 
      temporal and spatial resolution of 3D dynamic TR-CE-MRA TRICKS ASSET allowed a 
      better assessment of intracranial vascular malformations, namely better depiction 
      of feeders, drainers and better detection of early venous drainage. There was no 
      significant difference between them in terms of nidus size. CONCLUSION: 3D 
      dynamic TR-CE-MRA combining parallel imaging and a time-resolved method with 
      subsecond and submillimeter resolution could become the first-line investigation 
      technique in both diagnosis and follow-up of intracranial AVMs.
