In the past century, the technologies have advanced due to the discovery of X-rays, Arteriography, Magnetic Resonance Imaging (MRI), Magnetic Resonance Angiography (MRA), Computed Tomography (CT), Positron Emission Tomography (PET), Single Photon Emission Computed Tomography (SPECT) and Ultrasonography.
Advances in imaging technology have dramatically expanded the diagnostic capabilities of cardiologists. Cardiologists continue to expand their use of evolving imaging technologies such as Cardiac CTA and Cardiac MRA to enhance patient care. They are evaluating which imaging procedures are most effective for diagnosing a range of cardiac conditions, and are weighing the tradeoffs between acquiring imaging technologies for their practices and referring patients out for such testing.
• Cardiac CT and CT Angiography
• Cardiac MR and MR Angiography
• SPECT and SPECT/CT
• Cardiac Catheterization
• PET and PET/CT
Echocardiography continues to represent one of the top three diagnostic imaging modalities for ten of the twelve cardiac conditions.
The advancements in medical imaging over the past few decades have enabled the physicians to non-invasively peer inside the human body for the purpose of diagnosis and therapy. With the advent of medical imaging modalities that provide different measures of internal anatomical structure and function, physicians are now able to perform typical clinical tasks such as patient diagnosis and monitoring. Successful development of Computed Aided Diagnosis (CAD) scheme makes the radiologist to investigate the nature of the subjects. Recently organs being subject to research for CAD include the kidney, brain, liver, colon, chest, breast, vascular system and skeletal system.
