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

The new technologically advanced D-SPECT camera enables shorter image acquisition times, provides better image quality and opens the door to new diagnostic procedures using simultaneous multi-isotope imaging--providing the potential to revolutionize functional imaging, according to results released at SNM's 53rd Annual Meeting June 3? in San Diego.

"The potential of using more than one tracer and more than one isotope simultaneously means that more than one medical condition can be searched in one go--ultimately improving the diagnosis of cancer, heart and brain diseases," explained James A. Patton, professor of radiology and physics with the department of radiology and radiological sciences at Vanderbilt University Medical Center in Nashville, Tenn. "In addition, as the speed of this new D-SPECT camera approaches the imaging speed of computed tomography (CT), it will become economical to have functional and anatomic imaging in line (as a hybrid image) and in near real time for developing combined single photon emission computerized tomography (SPECT) and CT images," added the co-author of "D-SPECT: A New Solid State Camera for High-Speed Molecular Imaging."

"Patient health considerations and radiation safety standards limit the radiation dose that can be administered for the purpose of diagnostic imaging," said Patton. "In addition to this limitation, the low efficiency of existing SPECT imaging technology in collecting radiation imposes very long acquisition times of up to a full hour and sometimes more," he added. "This new camera technology enables acquisition times that are shorter by an order of magnitude (2 minutes vs. today's 20 minutes for a cardiac scan), better image quality (up to two times the image resolution) and the potential for new diagnostic procedures employing simultaneous multi-isotope imaging for more versatile diagnostics," he explained. "Due to its very high sensitivity (10 times higher) and definition (up to 2 times the re
