Summary

Purpose

1. To investigate the effects of cardiac imaging radiation on the induction of DNA double-strand breaks by enumerating gamma-H2AX foci in blood lymphocytes and plucked hair follicle cells.
2. To estimate whether the use of breast shields in cardiac computed tomographic angiography (CCTA) limits the effective radiation exposure of breast tissue.
