Objectives Radial approach invasive coronary angiography has been shown to be superior
to the femoral approach in terms of reducing vascular access complications and improving
patient comfort. However, one major limitation has been the perception of higher patient
radiation exposure, with guidelines recommending 7mSv as an appropriate average
effective dose (E) for routine coronary angiography. Therefore, we sought here to assess
differences in radiation exposure between the femoral and radial access routes in patients …
