CT ​Evaluation ​by ​Artificial ​Intelligence ​for ​Atherosclerosis, Stenosis an...

Background: Atherosclerosis evaluation by coronary computed tomography angiography (CCTA) is promising for coronary artery disease (CAD) risk stratification, but time consuming and requires high expertise. Artificial Intelligence (AI) applied to CCTA for comprehensive CAD assessment may overcome these limitations. We hypothesized AI aided analysis allows for rapid, accurate evaluation of vessel morphology and s...

Documento de Consenso sobre a Realização de Ressonância Magnética em Doentes co...

Magnetic resonance imaging (MRI) is currently considered an essential complementary method for diagnosis in many conditions. Exponential growth in its use is expected due to the aging population and a broader spectrum of clinical indications. Growth in its use, coupled with an increasing number of pacemaker implants, implantable cardioverter-defibrillators and cardiac resynchronization therapy, has led to a fre...

Circulating micrornas correlate with multiple myeloma and skeletal osteolytic l...

Multiple myeloma (MM) is the second most frequent hematological disease and can cause skeletal osteolytic lesions. This study aims to evaluate the expression of circulating microRNAs (miR-NAs) in MM patients and to correlate those levels with clinicopathological features, including bone lesions. A panel of miRNAs associated with MM onset and progression, or with bone remodeling, was analyzed in the plasma of 82...

The amount of late gadolinium enhancement outperforms current guideline-recomme...

BACKGROUND: Identifying the patients with hypertrophic cardiomyopathy (HCM) in whom the risk of sudden cardiac death (SCD) justifies the implantation of a cardioverter-defibrillator (ICD) in primary prevention remains challenging. Different risk stratification and criteria are used by the European and American guidelines in this setting. We sought to evaluate the role of cardiovascular magnetic resonance (CMR) ...

Palliative splenic irradiation for symptomatic splenomegaly in non-Hodgkin lymp...

INTRODUCTION AND AIMS: Splenic marginal zone lymphoma, an uncommon subtype of non-Hodgkin lymphoma (NHL), is usually present with symptomatic splenomegaly. Although splenectomy has long been considered the first-line therapy in symptomatic or cytopenic patients, it can lead to significant morbidity and mortality. Splenic irradiation is an option for patients who have a poor response to systemic therapy and/or a...

Tomografia Computorizada Cardíaca Prévia a Ablação de Fibrilhação Auricular - E...

Introdução: A capacidade de a TC cardíaca fornecer um mapa anatómico preciso e excluir a presença de trombo intracardíaco é conhecida. O objetivo deste estudo foi avaliar o impacto da otimização de protocolos e evolução tecnológica nas doses de radiação e contraste e na qualidade de imagem dos exames de TC cardíaca prévia a ablação de fibrilhação auricular (FA). Métodos: Registo prospetivo de doentes consecutiv...

Prognostic Value of Age Adjusted Segment Involvement Score As Measured by Coron...

Extent of coronary atherosclerotic disease (CAD) burden on coronary computed tomography angiography (CCTA) as measured by segment involvement score (SIS) has a prognostic value. We sought to investigate the incremental prognostic value of 'age adjusted SIS' (aSIS), which may be a marker of premature atherosclerosis and vascular age. Consecutive patients were prospectively enrolled into the CONFIRM (Coronary CT ...

Intracardiac mass from Burkitt's lymphoma in an immunocompromised patient: a ve...

Long-Term Prognostic Impact of CT-Leaman Score in Patients with Non-Obstructive...

BACKGROUND: Non-obstructive coronary artery disease (CAD) identified by coronary computed tomography angiography (CCTA) demonstrated prognostic value. CT-adapted Leaman score (CT-LeSc) showed to improve the prognostic stratification. Aim of the study was to evaluate the capability of CT-LeSc to assess long-term prognosis of patients with non-obstructive (CAD). METHODS: From 17 centers, we enrolled 2402 patients...

Modified Continuity Equation Using Left Ventricular Outflow Tract Three-Dimensi...

PURPOSE: Aortic valve area (AVA) is usually estimated by the continuity equation (CE) in which the left ventricular outflow tract (LVOT) area is calculated assuming a circular shape. This study aimed to compare measurements of LVOT area using standard 2D transthoracic echocardiography (2DTTE), 3D transesophageal echocardiography (3DTEE), and multidetector computed tomography (MDCT) and assess their relative imp...
