简要总结

The primary objective of this research project is development and validation of a new, non-contrast gated aortic (NCGA) computer tomography scan algorithm for screening of aortic aneurysm in the chest and abdomen in at risk patients. This study would initially be performed in patients with a known aneurysm and done in addition to their indicated surveillance CT scan.

详细描述

Study Design: Patients who agree to enroll in the study will get the NCGA study as well as a routine non-contrast computed tomography of chest/abdomen/pelvis within one year following recruitment at the patient's convenience. No follow-up will be required, but any clinically relevant findings on the testing will be communicated to the PCP through EPIC in-basket. Urgent findings, as determined by the primary investigator, will also result in a direct communication with the PCP. It is expected that any such findings will also be seen on the standard and clinically indicated CT which they are also undergoing, and so "new or unique" findings on the study NCGA test are not expected to occur. The final study visit will be the day of participation.

It is expected that any such findings will also be seen on the standard and clinically indicated CT which they are also undergoing, and so "new or unique" findings on the study NCGA test are not expected to occur. The final study visit will be the day of participation.

Study Procedures: One visit to complete one (1) non-contrast (no "dye"/contrast material will be injected) computed tomography (CT) scan of the chest, abdomen and pelvis. This visit will occur within one year following recruitment, scheduled at the patient's convenience. This one visit represents the totality of study participation for each participant.

Study Duration: For each individual, participation is only over one day - the day of the patient's non-contrast CT scan. No early termination visits or unscheduled visits apply.

The anticipated duration to complete enrollment of all participants is 1 year. Following completion of the study, the study team is planning for an interim period of 6 months for discussion and planning for future projects.
