Cardiac computed tomography (CT) scans include approximately 2/3 of the lung and can be obtained with low radiation exposure. Large cohorts of population-based research studies reported high correlations of emphysema quantification between full-lung (FL) and cardiac CT scans, using thresholding-based measurements. This work extends a hidden Markov measure field (HMMF) model-based segmentation m...

OBJECTIVE To evaluate a quantitative method for individually adjusting the tube current to obtain images with consistent noise in electrocardiogram (ECG)-gated CT cardiac scans. MATERIALS AND METHODS The image noise from timing bolus and cardiac CT scans of 80 patients (Group A) who underwent a 64-row multidetector (MD) CT cardiac examination with patient-independent scan parameters were anal...

UNLABELLED Artifacts related to metallic implants are an established limitation of CT-based attenuation correction (CT-AC) in PET/CT. However, the impact of metallic components of pacemaker leads and implantable cardioverter defibrillator (ICD) leads on the accuracy of cardiac PET has not been evaluated. The goal of this study was to investigate the magnitude of artifacts related to pacing and ...

Intra-cardiac masses present an important problem in cardiology. The differential diagnoses includes tumours, which may be primary (benign or malignant) or metastatic, and infected mural thrombi.Myxomas, sarcomas, breast, lung and renal cancer represent the commonest causes of primary benign, malignant and metastatic intra-cardiac masses, respectively.Recent studies have shown that cardiac invo...

The article deals with changes in the brain (according to MRI data), and associated processes lungs abdomen CT occurring at clinical death, resulting subsequent recovery of cardiac activity.

PURPOSE OF REVIEW Cost-effective care pathways are integral to delivering sustainable healthcare programmes. Due to the overestimation of coronary artery disease using traditional risk tables, non-invasive testing has been utilised to improve risk stratification and initiate appropriate management to reduce the dependence on invasive investigations. In line with recent technological improvement...

conclusions rotem can be used to detect postoperative hemostatic changes following cardiac surgery appropriately and can be useful to choose suitable blood products that may reduce the need for blood transfusion, contributing to better patient blood management. background coagulopathy after cardiopulmonary bypass (cpb) may lead to increased morbidity and mortality. routine conventional coagulat...

Cardiac computed tomography (CT) for Calcium Scoring uses special x-ray equipment to examine the coronary arteries. The exam can determine your risk for heart disease. Cardiovascular disease is the leading cause of death in both men and women in America, but it is largely preventable. If detected early, it can be stopped or reversed. Cardiac screenings are of particular importance to patients w...

The recently developed 64-slice CT scanner together with the use of 2-D and 3-D reconstructions can aid the cardiovascular surgeon and interventional radiologist in visualizing exact geometric relationships to plan and execute complex procedures via minimally invasive or standard approaches. Cardiac 64-slice CT considerably benefits from the high temporal and spatial resolution allowing the rel...
