ABSTRACT
PURPOSE:
To compare the accuracy of non-electrocardiogram (ECG)-gated CT angiography (CTA), single-diastolic-phase ECG-gated CTA, and full-phase ECG-gated CTA in detecting the intimal tear (IT) in aortic dissection (AD) and ulcer-like projection (ULP) in intramural hematoma (IMH). MATERIALS ANDMETHODS:
A total of 81 consecutive patients with AD and IMH of the thoracic aorta were included in this single-center retrospective study. Non-ECG-gated CTA, single-diastolic-phase ECG-gated CTA, and full-phase ECG-gated CTA were used to detect the presence of the IT and ULP in thoracic aortic regions including the ascending aorta, aortic arch, and proximal and distal descending aorta.RESULTS:
The accuracy of detecting the IT and ULP was significantly greater using full-phase ECG-gated CTA (88% [95% CI 100%, 75%]) than non-ECG-gated CTA (72% [95% CI 90%, 54%], P = 0.001) and single-diastolic-phase ECG-gated CTA (76% [95% CI 93%, 60%], P = 0.008).CONCLUSION:
Full-phase ECG-gated CTA is more accurate in detecting the IT in AD and ULP in IMH, than non-ECG-gated CTA and single-diastolic-phase ECG-gated CTA.Palabras clave
