Patients to benefit from novel technology revolutionizing high-speed molecular imaging

solution) and novel scanning design--together with usage of high-energy discrimination of the solid state detectors--this new technology can open the way to personalized diagnostics taking into account patient-specific physical information," noted Patton.

"For 50 years, physicists have been struggling with the inherent trade-off between spatial resolution and sensitivity associated with radionuclide imaging," said Patton. "D-SPECT collects photons with much higher efficiency (order of magnitude) due to usage of a split–scanning detector design capable of dwelling more on the organ of interest. This, together with radiation collection angles larger than in existing technology, constitutes a radical departure from the conventional Anger camera," he detailed. Besides providing improved statistics leading to better image quality and the potential for better and earlier diagnosis of diseases, the D-SPECT camera reduces the time a patient spends on imaging equipment, said Patton. Patients receive a lower radiation dose, and personalized scanning takes into account unique patient physiology and anatomy, he added. "Simultaneous imaging of a combination of radiopharmaceuticals can be used to define a specific disease signature leading to noninvasive biopsy," he detailed. The D-SPECT camera will provide "a potential breakthrough in organ-specific (heart) SPECT imaging," said George Zubal, SNM's Scientific Program Committee instrumentation and data analysis vice chair and associate professor of diagnostic radiology and technical director of nuclear medicine at Yale University in New Haven, Conn.

Researchers from Spectrum Dynamics, Haifa, Israel; Vanderbilt University Medical Center; Cedars-Sinai Medical Center, Los Angeles; Stanford University, Stanford, Calif.; and New York Presbyterian Hospital–Weill Cornell Campus, New York, N.Y., will now focus on specific clinical applications for the D-SPECT camera. "The first such application will be in cardiac perfus
