The sympathetic nervous system (SNS) is important in cardiac pathophysiology. By increasing heart rate and arterial blood pressure, the SNS plays a central role to adapt cardiac performance to conditions of increased external needs. Accordingly, a sympathetic surge instantaneously ameliorates left ventricular (LV) contractility and relaxation, abruptly increasing cardiac working capacities. How...

Introduction Cardiac MR imaging allows for the examination of anatomy, function, and metabolism and its clinical use is steadily increasing. It poses unique challenges to the imaging protocols as it requires high spatial resolution over a larger volume in the presence of cardiac and breathing motion. This overview of cardiac MRI discusses methods to reduce motion artifacts and various clinical ...

Imaging of cardiac function and anatomy has advanced at an exponential rate over the past two decades. Our ability to quantitatively assess the degree of myocardial ischemia and accurately define the vascular anatomy using noninvasive techniques is greater than ever before. Current advances is cardiac imaging are allowing us to more safely assess patients for myocardial ischemia and better unde...

Myocardial perfusion imaging can predict outcomes in cardiac patients. However, limited data exist regarding its prediction of cardiovascular outcomes in cancer patients. We sought to determine whether myocardial perfusion imaging predicts long-term cardiovascular outcomes in cancer patients.We performed a retrospective review of 787 consecutive patients at our institution who underwent myocard...

OBJECTIVES The purpose of this study was to describe radiation exposure from cardiac imaging procedures over time in a general population. BACKGROUND Cardiac imaging procedures frequently expose patients to ionizing radiation, but their contribution to effective doses of radiation in the general population is unknown. METHODS We used administrative claims to identify cardiac imaging procedu...

Introduction: The existing cardiac coil in the market is an 8-channel coil with 4 anterior loops and four posterior loops with a fieldof-view coverage of 30 cm by 30 cm. One finds that the clinical demand for cardiac coils is split into two segments: one is those coils which are solely for cardiac imaging with a field-of-view requirement of 30 cm by 30 cm to cover the heart only; the other segm...

Introduction: One of the most important causes of death in patients with end-stage renal disease (ESRD) and even after kidney transplantation is cardiovascular diseases. Thus, cardiac evaluation is of utmost importance in the management of these patients especially during preoperative work up before renal transplantation. The aim of present study is to evaluate the role of myoc...

Myxoma jantung merupakan tumor jinak primer yang paling umum, biasanya ada di atrium kiri dengan titik perlekatan daerah fossa ovalis. Modalitas pencitraan untuk diagnosis myxoma antaranya ekokardiografi, computed tomography (CT), magnetic resonance imaging (MRI). Cardiac is the most common primary benign heart tumor, usually in left with an attachment point ovalis area. Many modalities for car...

BACKGROUND Cardiac magnetic resonance imaging is considered the gold-standard method for the calculation of cardiac volumes. Transthoracic impedance cardiography assesses the cardiac output. No studies validating this measurement, in comparison to that obtained by magnetic resonance imaging, are available. OBJECTIVE To evaluate the performance of transthoracic impedance cardiography in the ca...

a one-month-old male terrier dog was referred in shock status with a history of anorexia, tachypnea, abdominal distention and progressive weight loss. auscultation of right side of the lungs found enhanced respiratory noises. the thorough auscultation of the opposite side of the chest revealed the presence of typical intestinal sounds. cardiac auscultation revealed muffled heart sounds and a di...
