LTRC Scans - Historical CT Scan

The lowest preference for collecting CT data from patients enrolled in the LTRC that still fulfills the requirements for CT scanning is a CT scan of the chest previously obtained for clinical reasons. 

These historical exams must have been obtained less than six months from the time of evaluation at the Clinical Center and must also be in digital format for transfer to the RCL. 

The participant must consent to use of this clinical scan for research purposes, its storage at the Mayo Clinic or another repository designated by the NHLBI, and the sharing of results and anonymized image data with future researchers as part of the LTRC data repository. 

If more than one historical exam is available, the most recent examination with high-resolution CT images (1.0 to 1.5 mm) will be sent to the RCL for analysis and storage.
