For that purpose, CTA is less effective in patients with calcium score greater than or equal to 600 and in patients with a high pre-test probability for obstructive CAD. (CTA is most useful as a rule-out test in patients with low-intermediate pre-test probability of disease and mild corona...
Non-significant CAD was defined by: QCA as less than 70 % stenosis; or coronary computed tomography angiography (CTA) as less than 30 % stenosis and a calcium score of 0 in all vessels. Automatically generated MBF maps were compared with manual quantification on healthy volunteers. Diagnostic p...
Within each recorded tissue area, the fluorescent intensity of calcium spikes for five locations of interest was plotted over 8 s. The resultant calcium transients in both the primary and branch channels displayed strong and synchronous calcium mobilization, indicating the synchronous beating of the ...
