  • Title: Fast CT for aortic dissection.
    Author: Small JH, Dixon AK, Coulden RA, Flower CD, Housden BA.
    Journal: Br J Radiol; 1996 Oct; 69(826):900-5. PubMed ID: 9038523.
    Abstract:
    Results were evaluated in 81 patients with suspected acute aortic dissection who were examined on a fast CT system capable of a 1 s data acquisition time. 17 patients had Type A and nine had Type B dissections. Radiological assessment provided 78 confident reports and expressed some uncertainty about the diagnosis in three patients. Overall sensitivity for aortic dissection was 96.2% and specificity was 96.4%. When 78 confident reports alone were considered, both sensitivity and specificity reached 100%. Reconstruction of data at 100 ms intervals allowed discrimination between artefacts in the ascending aorta and Type A dissections. CT can often be used as the single investigation prior to surgery for acute Type A dissections.
