Aortic dissection: sensitivity and specificity of MR imaging.
Why the study?
What is the sensitivity and specificity of MR imaging for diagnosing aortic dissection, and how does reader experience affect accuracy?
Population
54 patients (35 male, 19 female; aged 16-90 years) with suspected or known aortic dissection
Comparison
Gated transverse magnetic resonance (MR) imaging vs Reference standard
Design
Cross-sectional, Reviewers were blinded to clinical details

Implication
Reader experience warrants caution in MR interpretation of aortic dissection; leaves open prospective validation of training effects.

Population

I
Intervention
Gated transverse magnetic resonance (MR) imaging
C
Comparator
Reference standard (proved aortic dissections and normal cases)
O
Outcome
Sensitivity and specificity for the presence or absence and type of aortic dissectionsurrogate
MR imaging is highly sensitive and specific for diagnosing aortic dissection, but diagnostic accuracy depends heavily on the reader's experience.
