Can a cardiac PET scan detect cancer?

A PET scan is an effective way to help identify a variety of conditions, including cancer, heart disease and brain disorders. Your doctor can use this information to help diagnose, monitor or treat your condition.

Can cancer hide from a PET scan?

TUESDAY, Jan. 12 (HealthDay News) — A combination whole-body PET-CT scan is more accurate than some other commonly used tests in detecting cancer in patients with neurologic symptoms, according to U.S. researchers.

Is a cardiac PET scan the same as a cancer PET scan?

A PET scan is not as accurate for very small cancers however, so very early scans may not show anything. Cardiac PET scans could show a doctor that blood flow to the heart is completely normal but could also show that things are going wrong.

What is TOF in PET scan?

Time-of-flight (TOF) PET was initially introduced in the early days of PET. TOF PET scanners developed in the 1980s had limited sensitivity and spatial resolution, operated in 2D mode with septa, and used analytic image reconstruction methods.

What color is cancer on PET scan?

Cancer. Cancer cells can have a higher metabolic rate than noncancerous cells. Because of this high level of chemical activity, cancer cells often show up as bright spots on PET scans.

Why would a cardiologist order a PET scan?

A heart PET scan can detect whether areas of your heart muscle are receiving enough blood, if there is heart damage or scar tissue in the heart, or if there is a buildup of abnormal substances in the heart muscle.

What is the main benefit of adding time of flight measurement to the PET scan?

TOF has the potential to improve the accuracy of a lesion uptake measurement through better signal localization and reduced noise propagation.

What is a PET tracer?

A PET radiotracer (also known as PET tracer) is a positron-emitting radiopharmaceutical used in positron emission tomography (PET). Each tracer consists of a positron-emitting isotope (radioactive tag) bound to an organic ligand (targeting agent).

Why would an oncologist order a PET scan?

PET imaging can be useful to determine whether a tumor is malignant (cancerous) or benign (not cancerous). Unlike other imaging tests like CT or MRI that show anatomy, the PET scan looks at the physiological changes and cellular activity, so cancer may be diagnosed much earlier.
