In another sign that Dr. Davis and Track Your Plaque had it right all along, a small study at Beth Israel Deaconess Medical Center of the RCadia Automated CT Analyzer provided a high negative predictive value and may help move patients quickly through the emergency room.
"the algorithm of ECG, serial enzymes, and perfusion imaging is both expensive as well as time-intensive, so clearly there is a need for a quick noninvasive test, and recent studies have shown that [coronary computed-tomography angiography] CCTA fits the bill very nicely. But there are problems with CCTA—one of them is the off-hours availability of expert coronary CTA readers,"
The automated analyzer could have a role as a second reader in the emergency-department setting as an aid to normal expert CCTA readers. It's available at all hours, it interprets raw data—there's no waiting for 3D reformats—and there are cost savings to be had from rapid triage of this group of patients,"
Dr Girish Tyagi
Radiological Society of North America 2009 Scientific Assembly.
The study pitted the analyzer the consensus interpretation of two expert readers. For 100 analyzable studies, the automated analysis yielded a negative predictive value of 98%. The COR Analyzer's overall sensitivity was 83% and its specificity was 82%. RCadia Analyzer identified five of the six patients with significant stenosis found by the expert readers (five true positives, one false negative) and yielded 16 false positives and 78 true negatives.
Not perfect but the fact that "big money" is starting to invest in the technology and hospitals are beginning to use CCTA as a replacement for the expensive, time-consuming (and wasting) series of ECGs, enzyme tests, and perfusion studies speaks volumes!

Good news for cardiac patients! Heart attack no longer mean loss of life. We just have to be smart, take the necessary precautions, and make the right lifestyle choices. If we do this, there is no reason to believe that we cannot live a long and healthy life.I hope you will also make it yours.

Automatic analyzer could play a role as second reader is an emergency department, where an expert to help regular readers CCTA. Will be available at all hours, interprets the raw data does not need to wait for 3D formats and cost savings has been the rapid triage of this group of patients.
New technology, high-density lipoproteins (HDL) movement, or follow nutritionists "good cholesterol" than as a reference for what. HDL, and of course the most dangerous artery plaques in arterial walls are included to help you try to eliminate them. Visual HDL isolated from these plaques and researchers infused with nanoparticles of gold set. Then you can easily key gold HDL was injected into mice using multicolor communication and whistles can get.
If the patient is not comfortable, they will fidget, which impacts the quality of the image,” says Stokes. “Being at ease can not only make a difference in terms of what radiologists can see and diagnose, it makes for an overall better patient experience. They are much happier.
Visual HDL isolated from these plaques and researchers infused with nano particles of gold set. These all are great to know about it.
Well, I am the first time on this site and am really enthusiastic about and so many good articles.
It is superb technology with the excellent information. It is right example of new technologies.
This is very high technology by which we can know about the position of heart. It is eye for doctor to see heart situation properly.
Wow this is great news for the heart problem people.This is great news for the all people .This technology is good for the all information related heart and its disease also.

I real all the information about how to keep our heart healthy. It's nice to see that latest heart technology done great job and always ready to protect heart from various heart diseases.
Very nice blog I read it and inspire with get nice information. Thank you so much for sharing with us.

I am really impressed by this blog!Very clear explanation of issues is given and it is open to everyone.It contains true and fair information. Your website is very useful.
Thanks for some other informative web site. The place else could I am getting that kind of info written in such an ideal approach? I have a venture that I am just now operating on, and I have been on the look out for such information.
