Key result

Fast CT for suspected acute aortic dissection demonstrated an overall sensitivity of 96.2% and specificity of 96.4%, reaching 100% for both when only confident radiological reports were considered.

Why the study?

Does fast CT accurately diagnose acute aortic dissection in patients with suspected acute aortic dissection?

Implication

Fast CT provides high sensitivity and specificity for diagnosing acute aortic dissection, potentially serving as the sole preoperative investigation for Type A dissections.

Key Points

To evaluate the efficacy of fast CT in diagnosing acute aortic dissection in patients.
81 patients with suspected acute aortic dissection assessed using a fast CT system with 1 s data acquisition.
Radiological assessment evaluated confidence in the diagnosis, aiming for high sensitivity and specificity.
Data reconstruction at 100 ms intervals was utilized to differentiate between artefacts and dissections.
Overall sensitivity for aortic dissection was 96.2% and specificity was 96.4%.
For the 78 confident reports, both sensitivity and specificity reached 100%.
CT often serves as the primary investigation before surgery for acute Type A dissections.
