Imaging is a noninvasive complement to traditional methods (such as histology) in rodent cardiac studies. Assessments of structure and function are possible with ultrasound, microcomputed tomography (microCT), and magnetic resonance (MR) imaging. Cardiac imaging in the rodent poses a challenge because of the size of the animal and its rapid heart rate. Each aspect in the process of rodent cardi...

Imaging is becoming increasingly important in the management of cardiac arrhythmias as treatment moves away from long-term medication to curative radiofrequency ablation (RFA). With the complexity of the arrhythmias being treated in cardiac catheterization laboratories, information from echocardiography, computed tomography, and magnetic resonance imaging (MRI) are increasingly being used in pl...

Introduction: Cardiac myxoma is a benign and rare tumor, which can present with a grim phenomenon if the presentation is late or the diagnosis and surgery are delayed. The purpose of this study was to share our institutional experience of cardiac myxoma. Material and Methods: This retrospective study was conducted to evaluate patients undergoing procedures at a single tertiary care centre for t...

Purpose: The fundamental spatial resolution of in vivo MR lung imaging is limited by motion in thoracic cavity [1]. This problem is particularly evident in microscopic lung imaging of rodents because of their high cardiac (400-700 bpm) and breathing rate (100-150 breaths/min). To overcome these limitations several methods have been proposed, including scan-synchronous ventilation [2] and cardia...

Stress echocardiography and myocardial perfusion imaging are commonly used noninvasive imaging modalities for the evaluation of ischaemic heart disease. Both modalities have proved clinically useful in the entire spectrum of coronary artery disease. Both techniques can detect coronary artery disease and provide prognostic information. Both techniques can identify lowrisk and high-risk subsets a...

In this paper, we review novel techniques in the emerging field of spatiotemporal 4D PET imaging. We will discuss existing limitations in conventional dynamic PET imaging which involves independent reconstruction of dynamic PET datasets. Various approaches that seek to attempt some or all of these limitations are reviewed in this work, including techniques that utilize iterative temporal smooth...

Introduction:Myocardial 18F-FDG uptake is highly variable in oncologic whole body 18F-FDG PET/CT studies, ranging from quite intense to minimal distribution. Intense or heterogeneous myocardial 18F-FDG uptake is undesirable as it may interfere with the visual or quantitative evaluation of tumoral invasion and metastases in pericardium, myocardiu...

Molecular imaging is non-invasive visualization and measurement of biological processes at the molecular and cellular level within a living organism. This review provides a description of the various molecular imaging techniques for imaging cardiovascular targets and their potential clinical implications. Molecular imaging has relied mainly on nuclear imaging, but advances in nanoparticle probe...
