Key inclusion criteria
Regarding the diagnostic capability of the FAI, a retrospective, multicenter study was conducted involving consecutive patients from five institutions who underwent CT for chest or back pain. These institutions included the Department of Cardiovascular Medicine at the University of Tokyo Hospital (January 2018-June 2020), Sakakibara Heart Institute (January 2018-December 2021), Division of Cardiovascular Medicine at Saitama Medical Center, Jichi Medical University (May 2017-December 2021), Department of Cardiology at Tokyo Metropolitan Police Hospital (January 2019-December 2022), and Department of Cardiology at Kanto Central Hospital (January 2018-June 2021).
Key exclusion criteria
The patients who met the following criteria were excluded from the study: Patients with a previous history of AAD, trauma patients, individuals who did not undergo non-contrast CT, or those with poor image quality of scans due to implants or intra-aortic balloon pumping. Furthermore, individuals who were exposed to tube voltages other than 120 kVp were also excluded to maintain a consistent imaging protocol in the study. We excluded cases of aortic dissection limited to the ascending aorta, abdominal aorta, or aortic arch, as well as patients with aortic rupture and those who had undergone thoracic endovascular aortic repair (TEVAR). For the prognostic evaluation, the focus was on patients with type B AAD. Patients who underwent surgical interventions, including TEVAR and total arch replacement during their hospital stay, were excluded. Patients who died or experienced recurrent dissection during the same index hospitalization were also excluded, along with those who did not undergo follow-up CT during their hospitalization.

The objective of this study is to evaluate the usefulness of the perivascular fat attenuation index in the diagnosis and risk stratification of patients with acute aortic dissection. This observational study will involve retrospectively analyzing patient data from multiple centers. It will focus on comparing FAI values obtained from non-contrast computed tomography scans in patients diagnosed with acute aortic dissection versus those without the condition. Additionally, the study will observe the correlation between FAI values and the incidence of adverse outcomes in these patients to assess its prognostic value.
