  Purpose
The purpose of this study is to look at the safety (what are the side effects) and efficacy (how well does it work) of Magnevist (the study drug) used for MRI of the aortic arch and cerebral branches. The results will be compared to the results of MRI taken without Magnevist, and with the results of your X-ray angiography.

Condition Intervention Phase
Cardiovascular Abnormalities Drug: Gadopentetate dimeglumine (Magnevist) Phase 3

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Multicenter, Open-label Study of the Safety (Open-label) and Efficacy (Open-label and Blinded Reader) of a Single Administration of Approximately 0.1 mmol/kg of Magnevist® Injection-enhanced Magnetic Resonance Arteriography (MRA) and 2-dimensional-time-of-flight (2D-TOF) MRA in Patients With Known or Suspected Disease of the Aortic Arch and Cerebral Branches Who Are Undergoing MRA of These Vessels With Intra-arterial Digital Subtraction Arteriography (i.a. DSA) as the Standard of Reference.

Primary Outcome Measures:
  • Accuracy, sensitivity, and specificity based on quantitative assessment of stenosis assesses by blinded reader [ Time Frame: Image creation after injection -evaluation at blind read ]

Secondary Outcome Measures:
  • Diagnostic confidence [ Time Frame: At blinded and/or open label read of the images ]
  • Visual assessment of stenosis [ Time Frame: At blinded and/or open label read of the images ]
  • Difference in degree of stenosis [ Time Frame: At blinded and/or open label read of the images ]
  • Other diagnostic findings [ Time Frame: At blinded and/or open label read of the images ]
  • Location and matching of stenosis [ Time Frame: At blinded and/or open label read of the images ]
  • Image quality [ Time Frame: At blinded and/or open label read of the images ]
  • Image evaluability and presence of artifacts [ Time Frame: At blinded and/or open label read of the images ]
  • Ability to visualize arterial segments [ Time Frame: At blinded and/or open label read of the images ]
  • Proportion of correctly categorized maximum stenosis per segment [ Time Frame: At blinded and/or open label read of the images ]
  • Number of evaluable segments [ Time Frame: At blinded and/or open label read of the images ]
  • Duration if 2D TOF and CE-MRA [ Time Frame: At blinded and/or open label read of the images ]
  • Patient management [ Time Frame: From baseline to 24 hours follow-up ]
  • Safety variables [ Time Frame: From baseline to 24 hours follow-up ]
