Although the excellent spatial resolution of multislice spiral computed tomography (MSCT) enables the coronary arteries to be visualized, its limited temporal resolution results in poor image reproducibility because of cardiac motion artifact (CMA) and hence limits its widespread clinical use. A novel retrospectively ECG-gated reconstruction method has been developed to minimize CMA. In 88 cons...

Background: The ideal position of suture annuloplasty relative to the aortic annulus (internal or external) remains unclear. This study aimed investigate effectiveness internal and external for isolated type 1 bicuspid valve (BAV) repair. Electrocardiogram (ECG)-gated computed tomography (CT) was used compare two techniques analyze their impact on annulus. Methods: We retrospectively analyzed 2...

OBJECTIVE Gated myocardial perfusion single-photon emission computed tomography (GSPECT) has been established as an accurate and reproducible diagnostic and prognostic technique for the assessment of myocardial perfusion and function. Respiratory motion is among the major factors that may affect the quality of myocardial perfusion imaging (MPI) and consequently the accuracy of the examination. ...

Automatic biomedical signal recognition is an important process for several disease diagnoses. Particularly, Electrocardiogram (ECG) commonly used to identify cardiovascular diseases. The professionals can determine the existence of diseases using morphological patterns ECG signals. In order raise diagnostic accuracy and reduce time, automated computer aided diagnosis model necessary. With adva...

We describe the anaesthetic management of a pair of thoracopagus twins of 14 months of age undergoing complex cardiac evaluation. Synchronous ventilation of the twins, needed for the ECG-gated magnetic resonance imaging-angiography, was achieved through a Carlens (Y) adaptor during procedures and transport. The complex logistical implications are obvious. We also describe the first use of bispe...

There is increasing role of computed tomographic (CT) in the assessment of acute chest pain in the emergency department especially when the diagnosis is not clear. We report a case where non ECG gated contrast enhanced CT in the emergency department for rule-out of pulmonary embolus guided to the actual diagnosis, which was, acute coronary event, as evidenced by the presence of perfusion defect.

Despite negative perspectives on their consequences, gated communities continue to spread in cities due to structural reasons such as globalization and economic neo-liberalism. Hence, there is a need to seek for a way of achieving a balance and make these communities livable. Due to agreement with economic market perspectives, livability principles might offer a solution for mediating the socia...
