Medical Imaging

Physicians utilize medical imaging to see inside the body to diagnose and treat patients. This includes computed tomography (CT), magnetic resonance imaging (MRI), X-ray, ultrasound, fluoroscopy, angiography,  and the nuclear imaging modalities of PET and SPECT. 

Advnaces in nuclear cardiac imaging include the use of PET, quantitative coronary flow reserve and the additional CT ro SPECT and PERT scans. #ASNC
