The exercise heart rate (HR) profile and its relation to cardiac function and arrhythmias were investigated in patients with hypertrophic cardiomyopathy (HC). Chronotropic response (CR) and heart rate recovery (HRR) were ...

Purpose: The reconstruction of positron emission tomography images is a computationally intensive task which benefits from the use of increasingly complex physical models. Aiming to reduce the computational burden by means ...

BACKGROUND: Although atherosclerosis is usually thought of as a disease of modernity, the Horus Team has previously reported atherosclerotic vascular calcifications on computed tomographic (CT) scans in ancient Egyptians. ...

La opción de un injerto vascular es una medida correctiva para pacientes con enfermedad arterial periférica o aneurismas y para acceso arteriovenoso en pacientes con hemodiálisis crónica. A partir de la colocación de una ...

Purpose of Review: Takayasu arteritis (TA) is a granulomatous inflammatory disorder that affects large vessels, especially aorta and its proximal branches. Its diagnosis can be extremely challenging due to the non-specificity ...

Objectives: The aim of this study was to explore the diagnostic performance of dual-energy computed tomography perfusion (DE-CTP) at different energy levels. Methods: Patients with known or suspected coronary artery disease ...

The correction of attenuation effects in Positron Emission Tomography (PET) imaging is fundamental to ob-tain a correct radiotracer distribution. However direct measurement of this attenuation map is not error-free and ...

The construction process of large scintillation cameras with continuous crystals is a complex problem affected by multiple variables, from the physical construction of the scintillation crystal to the dispersion in the ...

Pentalogy of Cantrell is a syndrome evidencing five anomalies: a midline, upper abdominal wall abnormality; lower sternal defect; anterior diaphragmatic defect; diaphragmatic pericardial defect, and congenital abnormalities ...

Objective: The aim of this paper is to try to corroborate a diagnostic marker in alcohol and substance abuse through brain imaging using Brain Spect, based on the pioneering work in psychiatry by Andreasen in 1988 in ...
