Why the study?

Does two-dimensional time-of-flight MR angiography accurately evaluate carotid artery stenosis compared to conventional angiography in patients with suspected carotid arterial disease?

Population

Patients with suspected carotid arterial disease (73 vessels studied)

Comparison

Two-dimensional time-of-flight magnetic… vs Conventional angiography

Design

Cross-sectional, Scored in a blinded manner by four experienced…

Implication

May support noninvasive carotid stenosis evaluation; leaves open prospective outcome trials before replacing angiography.

Structured PICO

Does two-dimensional time-of-flight MR angiography accurately evaluate carotid artery stenosis compared to conventional angiography in patients with suspected carotid arterial disease?

P
Population
Patients with suspected carotid arterial disease (73 vessels studied)
I
Intervention
Two-dimensional time-of-flight magnetic resonance (MR) angiography
C
Comparator
Conventional angiography
O
Outcome
Correlation of stenosis scores between MR and conventional angiographysurrogate

Two-dimensional time-of-flight MR angiography is a robust and accurate modality for characterizing carotid artery stenosis, correlating well with conventional angiography.
