The study on PET brain scanner showed that this technology could be advanced more in quality and spatial resolution of PET imaging. This is said by the team of medical researchers. PET stands for positron emission tomography. This is a prototype scanner in which semiconductor detectors are used.
This prototype has already been used for characterizing the brain disorder disease – epilepsy – and nasopharyngeal cancer. It proved successful. This technology could help better in the early diagnoses of other cancers, nervous disorder diseases and heart diseases especially cardiovascular disease. This also helps in assessing patient’s responses to therapies. Third benefit which is achieved through this scanner is it determines how efficiently the new drug is working in the patient’s body.
Yuichi Morimoto is the leading person in the team researching on this technology. This research work has been given the name of Performance of a Prototype Brain PET Scanner Based on Semiconductor Detectors. He is the senior researcher for Central Research Laboratory of Hitachi Ltd., Tokyo, Japan. He considered it the exciting development in the field of nuclear medicine. These semiconductor scanners possess great potential. They are having high energy resolution and flexibility to good extent in size and fine arrangement of detectors. These characteristics of scanners provide better PET images.
PET scan procedure is the molecular imaging procedure. All treatment procedures in this category are noninvasive and painless tests. Physicians feel much comfortable in diagnosing medical conditions and conducting research. Radioactive materials like radiopharmaceuticals or radiotracers are used in PET scanning procedure. These radioactive materials gather on the area of the body surface which is being examined. In the next process it emits gamma rays which enter into the body.
PET scanner detects this emitted form of energy. These devices are integrated with the computer. The absorbed amount of radiotracer is measured on the computer on the basis of information sent by the device. The computer produces images providing the information on the functioning of organs and other internal body parts to the cellular and molecular levels.
