The world’s first clinically operational molecular imager with lutetium oxyorthosilicate (LSO) technology—the biograph LSO, manufactured by Siemens Medical Solutions—has produced a precisely registered, combined positron-emission tomography (PET)/computed tomography (CT) image in 7 minutes at the Hong Kong Baptist Hospital. The biograph LSO imager uses the high-speed properties of LSO as the PET scintillator to provide shorter scan times and unmatched patient throughput.
The biograph LSO merges three components—the ECAT ACCEL PET scanner, the SOMATOM Emotion spiral CT scanner, and syngo multimodality software—into a powerful scanning device that creates a precisely registered molecular image in 15 minutes or less. The resulting image makes it possible for oncologists and other health-care providers to view detailed anatomy and the biological processes of internal organs and living tissue at the molecular level in a single, noninvasive diagnostic procedure.
In addition to the biograph LSO, the biograph is available with bismuth germanate (BGO) crystal technology—a proven and economic scintillator for quality high-resolution PET imaging. The first commercial installation of the biograph with BGO technology was completed last fall at Memorial Sloan-Kettering Cancer Center in Manhattan.
