Naviscan PET Systems a privately held company that manufactures and develops high-resolution PET scanners launched its second generation of PEM devices, the PEM Flex Solo II.
PEM Flex Solo II an organ-specific, high-resolution PET scanner. Solo II is intended for use as an adjunct imaging modality and utilizes Positron Emission Mammography (PEM). PEM is a specialized form of PET technology that provides radiologists, breast surgeons, oncologists and nuclear medicine a new tool to image and characterize the scope of the disease at a metabolic rate.
Photonics improvements in the new Solo II yields higher count rate sensitivity while maintaining resolution capabilities that image cancers as small as 1.5 - 2.0mm, unprecedented in any other modality. The Solo II has also added an articulating arm, a motorized C-arm, and compression capability, enabling technologists to more easily position patients for optimal views and improved chest wall access.
In addition to its superior resolution capabilities, studies have shown the PEM Flex system has demonstrated sensitivity and specificity greater than 90 percent for characterizing suspicious lesions. The system has a positive predictive value of 92 percent.
