[Overview of cardiac contrast examination using 64-row multislice CT].
ECG-gated multislice CT(MSCT)now supports not only morphological but also functional diagnosis. In order to improve accuracy in the functional analysis of cardiac motion, it is important to depict the endocardial and epicardial contours. The present study was conducted to evaluate a method in which contrast medium and physiological saline solution(saline)are injected simultaneously, and the iod...
متن کاملAssessment of cardiac function using multidetector row computed tomography.
In patients with suspected or documented heart disease, a precise quantitative and qualitative assessment of cardiac function is critical for clinical diagnosis, risk stratification, management and prognosis. Cardiac CT is increasingly being used in diagnosis of coronary artery disease. Initially multi-detector row computed tomography (MDCT) was used chiefly for detecting coronary artery stenos...
متن کاملDiagnostic performance of coronary angiography by 64-row CT.
BACKGROUND The accuracy of multidetector computed tomographic (CT) angiography involving 64 detectors has not been well established. METHODS We conducted a multicenter study to examine the accuracy of 64-row, 0.5-mm multidetector CT angiography as compared with conventional coronary angiography in patients with suspected coronary artery disease. Nine centers enrolled patients who underwent ca...
متن کاملGlobal Assessment of Cardiac Function Using Image Statistics in MRI
The cardiac ejection fraction (EF) depends on the volume variation of the left ventricle (LV) cavity during a cardiac cycle, and is an essential measure in the diagnosis of cardiovascular diseases. It is often estimated via manual segmentation of several images in a cardiac sequence, which is prohibitively time consuming, or via automatic segmentation, which is a challenging and computationally...
متن کاملAccelerating global cardiac function assessment in mice using compressed sensing
Introduction: Cine magnetic resonance imaging (cine-MRI) to assess global cardiac function in surgically or genetically modified mice is typically performed using single dedicated volume or surface coils, precluding the use of parallel imaging techniques to speed up the imaging process. Compressed sensing has been shown to accelerate the data acquisition process in MRI by sparse coding the sign...
