BACKGROUND: Coronary computed tomography angiography (CTA) is increasingly used as a test to rule out coronary artery disease (CAD) in patients with a low to intermediate pre-test probability of the disease. We used the database of the German CT registry, collected between 2009 and 2014 in a broad patient population, to analyze contemporary radiation dose associated with coronary CTA in clinical practice. PATIENTS AND METHODS: The prospective observational registry included a total of 7061 patients ≥18 years, referred to 12 participating centers for a clinically indicated cardiac CT examination...

Advances in imaging instrumentation and technology have greatly contributed to nuclear cardiology. Dedicated cardiac SPECT cameras incorporating novel, highly efficient detector, collimator, and system designs have emerged with the expansion of nuclear cardiology. Solid-state radiation detectors incorporating cadmium zinc telluride, which directly convert radiation to electrical signals and yield improved energy resolution and spatial resolution and enhanced count sensitivity geometries, are increasingly gaining favor as the detector of choice for application in dedicated cardiac SPECT systems...

This paper provides the current state of nuclear cardiology in China and contrasts it with the state of nuclear cardiology in the United States (US). The West China Hospital and New York-Presbyterian Hospital (NYPH) were used as representative hospitals to contrast nuclear cardiology in China and the US, respectively. In 2015, there were 101 medical cyclotrons, 774 SPECT or SPECT/CT, 240 PET/CT, and 6 PET/MR cameras in China. Most (~90%) of the nuclear cardiology studies are gated SPECT myocardial perfusion imaging (MPI), and ~10% are other types of studies including MUGA, PET/CT MPI, and viability studies...

A 39-year-old man with a history of sickle cell disease (SCD) presented with left leg weakness. He had a normal CT head and CT angiogram, but MRI head showed multiple acute bilateral cortical infarcts including in the right precentral gyrus. The MRI findings were more in keeping with an embolic source rather than stroke related to SCD, although it could not be ruled out. He also had an echocardiogram which revealed a patent foramen ovale. He was treated with antiplatelet therapy and also had red blood cell exchange transfusion...

BACKGROUND: Pregnancy in Marfan Syndrome (MFS) is associated with increased maternal risk of cardiovascular events. Given the maternal and genetic risks, pre-conception counselling is essential to facilitate informed choices. Multidisciplinary antenatal care with regular imaging is mandatory and best delivered through a Joint Cardiac Obstetric Service (JCOS). The aim of this study was to compare the care delivered in a JCOS against recognised international standards (European Society of Cardiology (ESC))...

A 75-year-old man collapsed on a golf course and received cardiopulmonary resuscitation from a bystander, including the use of a public automated external defibrillator (AED). The AED was discharged once, with return of spontaneous circulation. An air ambulance crew found the patient haemodynamically stable, with no acute abnormalities on a 12-lead ECG. He had reduced consciousness and a dilated left pupil. On contacting the patient's wife by telephone, she said that he had fallen and hit his head earlier that day...

During the last decade coronary computed tomography angiography (CTA) has become the preeminent non-invasive imaging modality to detect coronary artery disease (CAD) with high accuracy. However, CTA has a limited value in assessing the hemodynamic significance of a given stenosis due to a modest specificity and positive predictive value. In recent years, different CT techniques for detecting myocardial ischemia have emerged, such as CT-derived fractional flow reserve (FFR-CT), transluminal attenuation gradient (TAG), and myocardial CT perfusion (CTP) imaging...

German regulations require a license for using ionizing radiation in medicine. This license-called "Fachkunde"-varies for different medical procedures such as CT, fluoroscopy, radiography, or mammography. The required frequencies and training times also vary for different medical disciplines such as radiology, cardiology, vascular surgery, traumatology, nuclear medicine, and radiotherapy, among others. The quality criteria for a specific license require a minimum training time under supervision and a minimum frequency of a wide range of procedures...

INTRODUCTION: Acute pulmonary thromboembolism (PTE) is a life-threatening disease. Mortality in PTE still remains very high in spite of progress in diagnostic tools. Mortality rate is about 30% in patients with unrecognized acute PTE. METHODS: It is a single center observational study of 31 consecutive patients who were hospitalized in the Department of Cardiology at MS Ramaiah Memorial hospital between January 1, 2010 and June 2015. All the patients confirmed with diagnosis of acute PTE by CT scan (either HRCT or CTPA) were included in the study...

OBJECTIVES: Our main objective is to design a method of, and supporting software for, interactive correction and semantic annotation of narrative clinical reports, which would allow for their easier and less erroneous processing outside their original context: first, by physicians unfamiliar with the original language (and possibly also the source specialty), and second, by tools requiring structured information, such as decision-support systems. Our additional goal is to gain insights into the process of narrative report creation, including the errors and ambiguities arising therein, and also into the process of report annotation by clinical terms...

Cardiac catheterization has greatly contributed to the progress made in the management of congenital heart diseases (CHD). Initially used in diagnosis, it allowed the understanding of heart diseases, their anatomy and hemodynamics. Gradually, the development of interventional cardiology has played a major role in the management of these malformations (Patent ductus arteriosus [PDA] and atrial septal defect [ASD] closure, pulmonary dilatation, percutaneous pulmonary valve implantation…). The development of such technology was made possible through the concomitant development of imaging techniques: fluoroscopy, ultrasound, MRI and CT...

Over the years, thanks to the addition of new generation systemic agents, as well as the use of more advanced and precise radiotherapy techniques, it was able to obtain a high curability rate for breast cancer. Anthracyclines play a key role in the treatment of breast disease, with a well-known benefit on disease-free survival of patients with positive nodal status. Trastuzumab have shown a significant outcome advantage after 1-year administration in case of HER2-positive disease. Unfortunately, significant increase in cardiotoxicity has been observed after anthracyclines and trastuzumab therapies...

OBJECTIVES: This study sought to determine prognostic value of nonobstructive coronary artery disease (CAD) for atherosclerotic cardiovascular disease (ASCVD) events and to determine whether incorporation of this information into the pooled cohort equation reclassifies recommendations for statin therapy as defined by the 2013 guidelines for cholesterol management of the American College of Cardiology and American Heart Association (ACC/AHA). BACKGROUND: Detection of nonobstructive CAD by coronary computed tomography angiography may improve risk stratification and permit individualized and more appropriate allocation of statin therapy...

BACKGROUND: Congenital heart disease (CHD) is the most common human birth defect, and clinicians need to understand the anatomy to effectively care for patients with CHD. However, standard two-dimensional (2D) display methods do not adequately carry the critical spatial information to reflect CHD anatomy. Three-dimensional (3D) models may be useful in improving the understanding of CHD, without requiring a mastery of cardiac imaging. The study aimed to evaluate the impact of 3D models on how pediatric residents understand and learn about tetralogy of Fallot following a teaching session...
