0626T Intraprocedural coronary fractional flow reserve (FFR) with 3D functional mapping of color-hyphencoded FFR values for the coronary tree, derived from coronary angiogram data, for real-hyphentime review and interpretation of possible atherosclerotic stenosis(es) intervention (List separately in addi...
A, Multiplanar reformat of a CT angiogram demonstrating obstructive stenosis of the proximal portion of the left anterior descending artery (LAD) and a computed fractional flow reserve (FFRCT) value of 0.62, indicating vessel ischemia. Invasive coronary angiogram demonstrates obstructive stenosis of the...
particularly myocardial infarction (MI) (10), and a recent 2018 paradigm-shifting New England Journal of Medicine publication showed 5-year hard outcomes that were clearly in favor of coronary CTA, with less invasive angiograms compared with standard of care after the 12-month follow-up point (...
Coronary CT angiography (coronary CTA) provides information about the occluded segment, which cannot be obtained from invasive angiograms (XA). We therefore hypothesized that preprocedural coronary CTA may improve success rates of percutaneous coronary intervention (PCI) for coronary arteries (CTO). 30...
MDCT Angiography as a Coronary Angiogram Equivalent Noninvasive evaluation of coronary anatomy via CA-CTA has been shown to provide rapid and accurate noninvasive coronary angiography. Several recent studies with MDCT (16-section) have shown sensitivities ranging between 92% and 95%, and specificities...
have demonstrated increased diagnostic accuracy compared to anatomical imaging and a reduction in invasive catheterization procedures23,24,25. Patient-specific simulations have also shed light on biomechanical stimuli data, such as wall shear stress, that correlate with CAD progression and vein graft failu...
an arterial first-pass image of the myocardium, without requiring any additional contrast agent or radiation dose; (2) a dedicated CT late enhancement technique, which would typically be added to a CT coronary angiogram as a second imaging procedure, and thus, requiring additional radiation dose ...
The final angiogram demonstrates appropriate stasis with no further tumor blush seen. Lipiodol uptake in the tumor is present (arrowhead) (E). Follow-up CT at 1 week demonstrates Lipiodol deposition within the targeted caudate lobe lesion (arrowhead) (F). Mechanism of Action The mechanisms for ...
It is difficult to opacify different structures simultaneously and invasive angiograms provide 2-dimensional imaging planes, often requiring multiple different injections to properly outline the object of interest. Since the introduction of newer imaging modalities, catheterization is primarily used for ...
(b) Pre-TARE angiogram, performed after selective catheterization of the arterial feeder of the active tumor tissue detected by PET/CT, showed the hypervascularized tumor (arrow). (c)90Y-PET acquired 4 h after TARE demonstrated90Y-microsphere deposition in the treated tumor (arrow). (d) At...
