“…The value of RT3DE imaging in this context has been demonstrated by multiple studies that compared RT3DE volume measurements with widely accepted reference techniques, including radionuclide ventriculography and cardiac magnetic resonance (CMR). [2][3][4][5][6] These studies and others have demonstrated higher levels of agreement between the RT3DE approach and the respective reference technique compared with conventional 2DE methodology. Additionally, RT3DE measurements were found to be more reproducible than 2DE 4,5,7 and, in some studies, even as reproducible as CMR.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…The accuracy in stroke volume by comparison of electromagnetic flow with echocardiographic measurements has been shown previously (yϭ0.92xϩ3.8, rϭ0.86). 13 The approach of using 2D echocardiography to calibrate the conductance data has also been used successfully by other investigators. 14 LV volume and pressure signals were digitally acquired with 1-ms resolution with a multifunction I/O board (AT-MIO-16, National Instruments) interfaced with a computer workstation (Pentium, 200 MHz) with customized software developed with LabView (National Instruments).…”
