Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
First patient first visit: 28 Oct 2009. Last patient last visit: 12 Oct 2010. Location: radiology departments

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
A total of 211 patients fulfilling the eligibility criteria were enrolled, of which 187 patients received Dotarem and completed the study. Twenty-four patients did not receive Dotarem and were discontinued prematurely.

Reporting Groups
  Description
TOF MRA Followed by Dotarem-enhanced MRA

Each patient will undergo a Time Of Flight (TOF) Magnetic Resonance Angiography (MRA) followed by a Dotarem-enhanced MRA.

Each patient will be scheduled to undergo CTA either before TOF MRA or after Dotarem-enhanced MRA. CTA will be used as standard of truth.
