Brief Take a look at Angiogram Procedure An interventional cardiologist, neurologist, or radiologist (physicians who use minimally invasive procedures to evaluate/take care of diseases) usually performs an angiogram within an outpatient clinic.
The BOD test depends on a measurable depletion of DO above a specified timeframe.
