Overview of Cardiac Contrast Examination Using 64-row Multislice CT

[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...

Clinical utility of 64-row multislice CT angiography in the detection of cerebral aneurysms in acute subarachnoid haemorrhage.

CT angiography (CTA) is a fast examination performed with a time-optimised contrast injection to enhance the cerebral arteries. Being a new imaging modality in our hospital, evaluation of the effectiveness of 64-row multislice CTA in detecting intracranial aneurysms in ruptured subarachnoid haemorrhage (SAH) cases is necessary. We conducted a descriptive prospective study by recruiting 30 conse...

Diagnostic 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...

Multislice CT cerebral angiography: the contrast studies for the imaging of 64-detector row spiral CT different tube voltage, tube current and CT energy spectrum on the radiation dose and image quality

Principles of CT: multislice CT.

This article describes the principles and evolution of multislice CT (MSCT), including conceptual differences associated with slice definition, cone beam effects, helical pitch, and helical scan technique. MSCT radiation dosimetry is described, and dose issues associated with MSCT-and with CT in general-as well as techniques for reducing patient radiation dose are discussed. Factors associated ...
