Identification of infarct substrates provides necessary guidance to the prevention and treatment of cardiac arrhythmias. Compared to diagnostic criteria of body surface potentials (BSP) or electrophysiological information on heart surfaces, the underlying volumetric cardiac electrical activity is of more direct clinical relevance in exhibiting patient-specific arrhythmic dynamics and arrhythmog...

Cardiac magnetic resonance imaging (CMR) is a useful non-invasive radiation-free modality for the management of patients with coronary artery disease (CAD). CMR cine provides “gold standard” assessment ventricular function, late gadolinium enhancement (LGE) data diagnosis and extent myocardial scar viability, while stress an established technique detection perfusion defects indicating ischemia....

Introduction Evaluation of cardiac morphology is an important part of routine diagnostic applications of cardiac MRI in various pathological conditions, such as congenital abnormalities, myocardial infarction, cardiomyopathies, and tumors. A previous technical approach for morphological cardiac MRI is based on a 2D black-blood fast spin-echo sequence with double inversion-recovery (DIR) blood s...

BACKGROUND Cardiac tumors, especially malignant, are rare but aggressive tumors that mostly arise from the mesenchymal cells and represent a challenging diagnosis for clinicians. Recently, fluorine-18-fluorodiography positron emission tomography and computed tomography (F-FDG PET/CT) is an increasingly popular new technique with diagnosis of tumor. METHODS We report a case of a right heart tu...

Recent technological innovations in CT and MR imaging of the heart have vastly expanded the clinical utility of these modalities allowing them to complement and in some ways surpass the capabilities of more traditional methods. Cardiac MR (CMR) has an unrivaled ability to assess contractile function, characterize tissue, and detect minute areas of scar. In turn, CMR can reliably risk stratify i...

Background Presenting symptoms in patients with Glu89Gln transthyretin (TTR) gene mutation are related to peripheral and autonomic nervous system damage; nevertheless, Glu89Gln TTR gene mutation is responsible for early and severe cardiac involvement (which significantly worsens the prognosis). Early diagnosis of cardiac involvement in subjects with TTR gene mutation can significantly affect pa...

INTRODUCTION Free-breathing cardiac cine imaging with respiratory and cardiac self-gating provides flexibility and convenience for patient scans. Here we propose a 3D radial cardiac cine imaging technique that improves upon self-gating by adding 3D respiratory motion correction. The 3D respiratory motion signals are derived from multiple projections through the data used for image reconstructio...

Background A comprehensive congenital cardiac MRI exam with contrast enhancement typically consists of multiple scans to evaluate dynamic contrast enhancement (DCE) characteristics, physiological function, blood flow, and anatomical assessment. However, multiple sequences require skilled operators, prolong the exam, and lengthen anesthesia duration for uncooperative patients. Thus, we propose a...

Cardiovascular magnetic resonance (CMR) is an established non-invasive technique to comprehensively assess cardiovascular structure and function in a variety of acquired and inherited cardiac conditions. A significant amount of the neck, thorax and upper abdomen are imaged at the time of routine clinical CMR, particularly in the initial multi-slice axial and coronal images. The discovery of uns...

Article type: Review article As a nuclear approach, Positron Emission Tomography (PET) is a functional imaging technique which is based on the detection of gamma ray pairs emitted by a positron‐emitting radionuclide. There are certain limitations to this technique such as normal tissue uptake. Therefore, it has been recommended that patients prepare before scanning. Fasting for a short while be...
