How do you interpret a thallium stress test?
What Do Your Thallium Stress Test Results Mean?
- Normal blood flow. If the two sets of images match and look healthy, you have normal blood flow.
- Abnormal blood flow during exercise.
- Low blood flow during both rest and exercise.
- No thallium visible in parts of the heart.
What does a thallium scan show?
A thallium (or cardiolite) scan uses a radioactive tracer to see how much blood is reaching different parts of your heart. These tests are the more common forms of tests called nuclear medicine scans.
What is a normal summed difference score?
Summed stress scores of less than 3 are considered normal, whereas scores of 4–7, 8–12, and 13 or higher are indicative of low, intermediate, and high risk for a hard cardiac event.
What are normal results for a stress test?
A normal result means blood flow through the coronary arteries is probably normal. The meaning of your test results depends on the reason for the test, your age, and your history of heart and other medical problems.
What are normal results for a nuclear stress test?
What are good nuclear stress test results?
Normal or abnormal, what does it mean? A normal test result indicates there is sufficient and unrestricted blood flow to your heart, both during periods of rest and exercise. Generally, there’s little concern for coronary artery disease and, in most cases, you won’t require any further testing.
What is a normal TID score?
The normal limits of TID ratios were 1.19, 1.23 and 1.46 for static and gated MPS on end-diastolic and end-systolic phase, respectively.
What is TMT positive?
Mildly positive TMT means that there might be a blockage in the blood supply to the heart. And when the patient is running or climbing stairs or during exertion stress the heart is not getting sufficient blood supply.
What is an abnormal nuclear stress test?
An abnormal stress test usually means that you have blockage in heart arteries. A nuclear stress test result should be interpreted in the light of a person’s symptoms, his risk for coronary artery disease etc. The nuclear stress test has the ability to quantify the severity of abnormality.
What is an abnormal TID score?
The threshold for an abnormal TID was 1.39 with specificity of 95% and sensitivity of 15% for determining multi-vessel CAD status. We conclude that the level of TID in gated SPECT MPI using regadenoson is associated with the degree of CAD on angiography.
What is a summed stress score?
The summed stress score (SSS) is a commonly used semiquantitative technique that combines the extent and severity of perfusion abnormalities into a single measure and has been shown to provide risk stratifi- cation in patients undergoing SPECT myocardial perfusion imaging (2).
