Digital and Cardiac Imaging

Cardiac magnetic resonance imaging uses a powerful magnetic field, radio waves and a computer to produce detailed pictures of the structures within and around the heart. Doctors use cardiac MRI to detect or monitor cardiac disease. They also use it to evaluate the heart's anatomy and function in patients with both heart disease present at birth and heart diseases that develop after birth. Cardiac MRI does not use radiation, and it may provide the best images of the heart for certain conditions.

Cardiac imaging refers to non-invasive imaging of the heart using ultrasound, magnetic resonance imaging (MRI), computed tomography (CT), or nuclear medicine (NM) imaging with positron emission tomography (PET) or single photon emission computed tomography (SPECT). These cardiac techniques are otherwise referred to as echocardiography, Cardiac MRI, Cardiac CT, Cardiac PET and Cardiac SPECT including myocardial perfusion imaging.

Magnetic Resonance Imaging is able to measure the size, shape, function, and tissue characteristics of the heart in a single session. It is more reproducible than echocardiography with less inter-observer variability, allowing for more precise reference ranges to better distinguish health from disease. Additional benefits from cardiac MRI include the ability to detect scar within the heart using late gadolinium enhancement, and identify other abnormalities of the heart muscle itself such as infiltration with iron or amyloid protein.

Computed tomography angiography (CTA), an imaging methodology using a ring-shaped machine with an X-Ray source spinning around the circular path so as to bathe the inner circle with a uniform and known X-Ray density. Cardiology uses are growing with the incredible developments in CT technology. Currently, multidetector CT, specially the 64 detector-CT are allowing to make cardiac studies in just a few seconds. These images are reconstructed using algorithms and software.

This special issue Digital and Cardiac Imaging focuses on publishing all the articles, research works related to the scope of this issue at cardiologyjournal@imedpub.com.


This special issue has been scheduled to release probably by June, 2022
