Cardiac magnetic resonance imaging: artefacts for clinicians [PDF]

Netherlands Heart Journal, 2014
In recent years, the clinical importance of cardiac magnetic resonance (CMR) imaging has increased dramatically. As a consequence, more clinicians need to become familiar with this imaging modality, including its technical challenges. MR images are obtained through a physical process of proton excitation and the reception of resonating signals. Besides

Cardiac involvement in consecutive elite athletes recovered from Covid‐19: A magnetic resonance study

Journal of Magnetic Resonance Imaging, 2021
Magnetic resonance (MR) studies suggested cardiac involvement post‐Covid‐19 in a significant subset of affected individuals, including athletes. This brings serious clinical concerns regarding the potential need for in‐depth cardiac screening in athletes

4-Dimensional Flow by Cardiac Magnetic Resonance Informs Surgical Planning in Partial Anomalous Pulmonary Venous Return

JACC: Case Reports, 2020
Four-dimensional flow cardiac magnetic resonance enhances the visualization of blood flow in a 3-dimensional volume throughout the cardiac cycle, thus dramatically improving visualization of pulmonary venous anatomy by cardiac magnetic resonance.

The Application and Research Progress of Cardiac Magnetic Resonance in the Assessment of Right Ventricular-Pulmonary Arterial Coupling [PDF]

Advanced Ultrasound in Diagnosis and Therapy
Right ventricular-pulmonary arterial coupling refers to the interaction and functional matching between the right ventricle and the pulmonary artery. When the coupling is disrupted, it can lead to a series of cardiovascular diseases, such as pulmonary ...

High Field Cardiac Magnetic Resonance Imaging [PDF]

Circulation: Cardiovascular Imaging, 2017
For a new technology, high-field cardiac magnetic resonance (CMR; 3.0 T≤B≤7.0 T) has come a long way. Not only has the number of reports referencing clinical applications risen,1,2 but prices for 3.0T systems have dropped almost 50% since the beginning of the millennium, and operational and service costs are virtually identical to those of 1.5T ...

Cardiac biomarkers as indicators of right ventricular dysfunction and recovery in chronic thromboembolic pulmonary hypertension patients after balloon pulmonary angioplasty therapy – a cardiac magnetic resonance imaging cohort study

Pulmonary Circulation, 2021
Background In chronic thromboembolic pulmonary hypertension, right heart failure determines outcome. Balloon pulmonary angioplasty therapy allows right heart recovery, which can be monitored by cardiac magnetic resonance imaging.

Magnetic Resonance Imaging as a Predictor of Survival Free of Life‐Threatening Arrhythmias and Transplantation in Cardiac Sarcoidosis

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundCardiac magnetic resonance imaging has a key role in today's diagnosis of cardiac sarcoidosis. We set out to investigate whether cardiac magnetic resonance imaging also helps predict outcome in cardiac sarcoidosis.
