Longitudinal images of the common carotid artery, triggered on the R-wave of the ECG, were magnified and recorded in DICOM format as a cine loop, on the hard drive of the ultrasound machine for later analysis.
However, in clinical practice, observers often utilises a cine loop to get an overview before carrying on with a more scrutinising search.
Optimal images will be triggered on the R-wave of the ECG and recorded in DICOM format as still images or as a cine loop onto CD for later offline analysis in the core laboratory.
The use of a cine loop allows selection of the maximal Doppler signal in that particular ROI given the variations with blood flow with cardiac output.
Images acquired in multiple cardiac phases using a restrospectively ECG-gated acquisition are displayed as a cine loop.
(To be clear, this is not a cine loop of PET tracer concentration over time).
AWBU software creates a cine loop of the images for interpretation, simulating the appearance of real-time imaging.
Selection of the best images from a cine loop is not required with SWE, a fact that should improve reliability.
Our results indicate that viewing BT image volumes horizontally is an alternative to consider when utilising FS only or combined with a cine loop at fast frame rates.
