Isotopes quite safe: Dyes are not used during nuclear stress tests. Trace radioactive isotopes are but there are no significant reactions to these minute doses used considering the thousands of tests done around the globe daily unless one has a history of being allergic to the thallium or cardiolite. ...Read more

How good is a cardiolite study for detecting potential heart attack?

How good is a cardiolite study for detecting potential heart attack?

Stress thallium: The study is made to look at the possibility of clogged arteries in the heart that can be more discernible with exercise or stress. If distribution of dye is poorer in some areas, these have to be defined with angiogram to be able to treat them. If there is diffuse disease and equalization, it can miss. If there are collaterals the area would still look good. It is not to predict mi, only vessels. ...Read more
