MONDAY, June 16 (HealthDay News) -- A prototype of a new cutting-edge PET scanner shows promise for the early diagnosis of disease, according to Japanese researchers.
They found that their semiconductor-based PET scanner was better than the conventional version at detecting partial epilepsy and nasopharyngeal cancer.

Eventually, the new technology could be used to provide early-stage diagnosis of other cancers, neurological disorders, and cardiovascular disease, the team said. It could also assess patients' responses to treatments and determine the efficacy of new drugs.
"This is an exciting development in the field of nuclear medicine," Yuichi Morimoto, senior researcher for the Central Research Laboratory of Hitachi Ltd. in Tokyo, said in a prepared statement.
"Our research indicates semiconductor scanners show great potential because of their high energy resolution and flexibility in both sizing and fine arrangement of detectors. These characteristics should lead to improved PET images and, in turn, major advances in the practice of nuclear medicine," Morimoto said in a prepared statement.
Morimoto and colleagues evaluated the performance of a prototype semiconductor-based PET brain scanner. Their findings were to be presented Monday at the annual meeting of the Society of Nuclear Medicine, in New Orleans.
In another study presented at the meeting, Pakistani researchers said a nuclear imaging technique called scintigraphy was more effective than the traditional barium X-ray method in detecting gastroesophageal reflux disease (GERD) in children with respiratory problems.
This study of 55 children found that scintigraphy -- in which a two-dimensional image is obtained through detection of radiation emitted by a radioactive source given to the body -- detected GERD in 66.6 percent of children.
