what's difference between thallium stress test and dobutamine stress
The stress thal is a combination of the exercise or dobutamine stress test followed by the injection of a nuclear tracer (thallium-99) to measure cardiac blood flow. The patient reaches the point of max stress (either exercise ro dobuta induced), gets the thallium injection and has images taken with the gamma camera to show perfusion.
