A New Semi-automated Algorithm for Volumetric Segmentation of the Left Ventricle in Temporal 3D Echocardiography Sequences.

Purpose: Echocardiography is commonly used as a non-invasive imaging tool in clinical practice for the assessment of cardiac function. However, delineation of the left ventricle is challenging due to the inherent properties of ultrasound imaging, such as the presence of speckle noise and the low signal-to-noise ratio.

Methods: We propose a semi-automated segmentation algorithm for the delineation of the left ventricle in temporal 3D echocardiography sequences.

A Novel 4D Semi-Automated Algorithm for Volumetric Segmentation in Echocardiography.

Segmentation of the left ventricle (LV) in temporal 3D echocardiography sequences poses a challenge. However, it is an essential component in generating quantitative clinical measurements for the diagnosis and treatment of various cardiac diseases. Identifying the endocardial borders of the left ventricle can be difficult due to the inherent properties of ultrasound.

Contrast Echocardiography without Contrast Agent for Display of Intraventricular Mass.

• Contrast echocardiography was scheduled for assessment of a cardiac mass. • A bright mass was displayed using very low MI contrast-specific imaging. • Histologic examination showed a papillary fibroelastoma.

What is the minimum change in left ventricular ejection fraction, which can be measured with contrast echocardiography?

Background: There are limited data on what is the minimum change that can be detected in cancer patients undergoing treatment with cardiotoxic drugs and are referred for monitoring left ventricular (LV) function.

Objective: To assess the variability in the measurement of LV volumes and ejection fraction (EF) in contrast echocardiography and to determine the minimum detectable difference (MDD) between two EF measurements that can be deemed significant.

Methods: A total of 150 patients were divided into three groups according to EF (EF <53, 53-60, and >60%).

Variability of left ventricular volume and ejection fraction measurements using contrast echocardiography: The influence of the left ventricular length measurements in a large cohort of patients during monitoring cardiotoxic effects of chemotherapy.

Objective: To investigate the influence of length difference in left ventricular (LV) long axis between the apical four-chamber and two-chamber views on measurements of LV volumes and ejection fraction (EF).

Methods: Seven hundred consecutive cancer patients underwent contrast echocardiography from July 2010 to May 2014. All patients received the echocardiographic contrast agent Definity.

Prevalence of coronary artery disease in different ethnic groups at a tertiary care hospital.

Objective: To compare the prevalence of coronary artery disease (CAD) between Thai Muslim and Thai Buddhist patients.

Material And Method: A hospital based retrospective study was carried out to investigate the prevalence of CAD and cardiovascular risk factors of these two ethnic and religious groups at Nopparat Rajathanee Hospital between June 2012 and December 2012. All Thai Muslim patients aged > or = 35 years who visited the internal medicine outpatient department (OPD) were studied.
