Primary Outcome Measures
NameTimeMethod
Overall Image Quality of MRA ImagesMRA examination

Number of images quoted with excellent and more than adequate quality in each group.

Image quality will be assessed on a 5-point scale:

1. Excellent

2. More than adequate

3. Adequate

4. Less than adequate

5. Non-diagnostic

Each image is analysed by 4 readers.

Secondary Outcome Measures
NameTimeMethod
Diagnostic ConfidenceMRA examination

Number of High/Excellent diagnostic confidence. Level of diagnostic confidence assessed on a 5-point scale by patient: nil, poor, moderate, high, excellent.

Each image is analysed by 4 readers.

Signal IntensityMRA examination

Signal to Noise ratio (SNR): SNR = SIa /NO SIa is the signal intensity measured in the ROI positioned in the artery. NO is noise defined as the standard deviation (SD) of signal intensity measured in the subtraction image (of the two non-enhanced scans) at the same location as the arterial ROI is to be measured.
