Recently, new cardiac imaging techniques as cardiac magnetic resonance have shown to play a primary role for a recognition of unusual mechanisms of right and left ventricular obstruction. However, echocardiography remains the most widely used technique and the first step to recognize myocardial hypertrophy, blood flow velocity, and pressure gradients in real time (2). We describe a rare case of...

background the present data show a global increase in the rate of cardiovascular disease. cardiac ct angiography has developed as a fast and non-invasive cardiac imaging modality following the introduction of multi-slice computed tomogaraphy. conclusions the total mean radiation dose to the thyroid and gonads was 0.36 msv, and 96.5 μsv, respectively for the subjects. these values were high for ...

Hypertrophic cardiomyopathy (HCM) is a condition of genetic mutation in the cardiac sarcomere that defined by hypertrophy, non-dilated left ventricle, and normal or increased ejection fraction. It presents with heterogeneous clinical picture which continues to challenge clinicians diagnose it clinically. Cardiac magnetic resonance (CMR) - non-invasive imaging technique an essential diagnostic t...

Abstract Purpose of Review This narrative review reflects on the body evidence cardiac 123 I- m IBG imaging that has accumulated since introduction in late 1970s and focusses to what extent fulfilled its potential cardiology especially. Recent Findings In contrast linear relationship between IBG-derived parameters overall prognosis heart failure, there seems a “bell-shape” curve for arrhythmic ...

Bifurcation lesions are present in one out of every five percutaneous coronary interventions. Despite the progress techniques, materials, and imaging technologies, bifurcation approach remains challenging, its treatment results higher rates adverse cardiac events when compared to with no involvement. The best technique treat is still a subject debate. For most cases, provisional preferred, sinc...

Introduction: Conventional gradient-echo based magnetic resonance imaging of lung parenchyma suffers from poor signal-to-noise ratios due to low proton density and short T2* caused by susceptibility gradients between airways and tissue. In addition, respiratory and cardiac motions seriously degrade the achievable image quality. Ultra-short echo time (UTE) MRI has recently gained renewed attenti...

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...

conclusion both techniques provided quantitatively consistent results of in vivo velocity vector fields in right internal carotid artery (rca). pc mri represented a good estimation of main flow patterns inside the vasculature, which seems to be acceptable for clinical use. however, limitations of each technique should be considered while interpreting results. subjects and methods mr imaging was...

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, myocardium or adjacent mediastinal structures. the diet, as...
