Computed Tomography Arteriograms (CTA) Volume Dose Reduction Study

• Status: Completed
• Trial end date: 2018-11-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of the study is to determine if the dose of contrast (Omnipaque) administered for Computed Tomography Arteriograms (CTA) can be reduced without degradation of image quality. The hypothesis is that there is no difference in image quality using ultra-low dose contrast in CTA exams compared to routine, standard of care dose exams.

• Phase: N/A
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Milton S. Hershey Medical Center

Criteria

Exclusion Criteria:

• Patients with no prior CTA imaging for comparison
