| 21. | Positron emission tomography ( PET ) scanning deals with positrons instead of gamma rays detected by gamma cameras.
|
| 22. | Is this even possible with modern gamma cameras ? talk ) 17 : 00, 5 February 2011 ( UTC)
|
| 23. | However, it is possible to acquire PET images using a conventional dual-head gamma camera fitted with a coincidence detector.
|
| 24. | It is very similar to conventional nuclear medicine planar imaging using a gamma camera ( that is, scintigraphy ).
|
| 25. | The Tc-99m then further decays, while inside a patient, releasing a gamma photon which is detected by the gamma camera.
|
| 26. | The isotopes are injected into the patient, and a special camera, called a gamma camera, takes pictures of the area.
|
| 27. | It is also possible to perform the scan with positron emission tomography ( PET ) rather than conventional gamma camera scintigraphy.
|
| 28. | Technetium-99m is used as a radioactive tracer and can be detected in the body by medical equipment ( gamma cameras ).
|
| 29. | The patient is placed under a gamma camera, which detects the low-level 140 keV gamma radiation being given off by technetium-99m.
|
| 30. | SPECT ( single photon emission computed tomography ) imaging, as used in nuclear cardiac stress testing, is performed using gamma cameras.
