What does a SPECT scan do?
What does a SPECT scan do?
A single-photon emission computerized tomography (SPECT) scan lets your doctor analyze the function of some of your internal organs. A SPECT scan is a type of nuclear imaging test, which means it uses a radioactive substance and a special camera to create 3-D pictures.
What is a normal summed stress 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.
How long does a SPECT CT scan take?
How long does a SPECT-CT scan take? It takes 30–40 minutes to obtain the SPECT and CT images, then you are allowed to leave.
How accurate are SPECT scans?
The results of the study showed SPECT diagnoses were true-positive in 37, true-negative in eight, false-positive in three, and false-negative in six patients. Sensitivity was 86%; specificity, 73% and the positive predictive value was 92%, with an accuracy of 83%.
What is the difference between a CT scan and a SPECT scan?
A SPECT scan is a type of nuclear medicine test that uses a radiotracer (a special contrast agent), that is injected through your vein. A CT scan uses X-ray radiation to provide thorough images of the structures inside your body (anatomy).
How do I read my stress test results?
Possible Conclusions
- Positive or abnormal: Doctors may conclude the stress test is positive for cardiac ischemia—meaning the heart muscle wasn’t getting adequate oxygenated blood during the stress.
- Negative or normal: A negative test result lacks any of the things that could trigger a positive conclusion.
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 the cost of a SPECT scan?
How Much Does a SPECT Scan Cost? SPECT scans are one of the more affordable ways to image the brain, but prices can fluctuate a lot based on location, the purpose of the scan, and what additional interpretation is involved. According to MDsave, brain SPECT scans range from $1,300 to over $3,500.
What is SPECT’s solution?
Our solution is a frictionless workflow and enables all healthcare staff to obtain quick results. We’re always looking to expand the diseases our platform tracks. The Spect solution is proudly deployed in over 8 states and 10 cities in the United States. We are heavily focused on screening the Senior Population.
What is SPECT used to diagnose?
SPECT can be helpful in determining which parts of the brain are being affected by: Dementia Clogged blood vessels Seizures Epilepsy Head injuries
How do you get a SPECT scan?
SPECT scans involve two steps: receiving a radioactive injection (called a tracer) and using a SPECT machine to scan a specific area of your body. You’ll receive a radioactive substance through an intravenous (IV) infusion into a vein in your arm. The tracer dose is very small.
Why integrate SPECT and CT in one imaging device?
The integration of SPECT and CT in a single imaging device facilitates anatomical localization of the radiopharmaceutical to differentiate physiological uptake from that associated with disease and patient-specific attenuation correction to improve the visual quality and quantitative accuracy of the SPECT image.
