HD-PET Provides Sharper, Clearer Images

New innovative high-definition positron emission tomography (HD-PET) technology has been developed to provide consistently sharper and clearly defined images across the entire field of view (FOV). The clarity achieved by HD-PET is the result of a unique and proprietary technology that optimizes the elements of image uniformity, resolution, and contrast.

Siemens Healthcare (Erlangen, Germany) honors the early adapters of its HD-PET technology at the 2008 Society of Nuclear Medicine (SNM) Scientific Sessions in New Orleans, LA, USA, June 14-18, 2008.

"HD-PET is a real technological advancement for challenging imaging situations, in particular, for small lesions and breath-dependent lesions,” said Prof. Dr. W. Mohnike, from the Diagnostic Therapy Center (Berlin, Germany).

Historically with PET imaging, intrinsic image quality has been known to degrade with increasing distance from the center of the detector, but with HD-PET, there is uniform resolution across the entire FOV. The improved resolution enables clinicians to clearly visualize small lesions from the center to the edges of the field of view.

Prof. Mike Fulham, from Royal Prince Alfred Hospital (Sydney, Australia, concurred. "Our HD-PET studies are a major improvement in study quality; they are clearer, provide better delineation and detection of small foci of disease; they offer improved confidence in diagnosis and diagnostic accuracy, which improves patient care,” he said.

HD-PET could potentially improve diagnosis and staging of disease, and therefore, clinical outcomes for patients. HD-PET, in combination with TrueV extended FOV, maximizes patient throughput and increases overall utilization. "Our Biograph 64 has enabled our hospital to image 49 patients in a single day, and our monthly record is 764 patients,” said Xu Zhensheng, director of Shanghai Fudan University-affiliated Huashan Hospital PET Center (Shanghai, China).
