In this article, the authors review novel techniques in the emerging field of spatiotemporal
four‐dimensional (4D) positron emission tomography (PET) image reconstruction. The …

With the arrival of increasingly higher-resolution PET systems, small amounts of motion can
cause significant blurring in the resulting images compared with the intrinsic resolution of the …

There are growing concerns about potential delayed, neuropsychiatric consequences (eg,
cognitive decline, mood or anxiety disorders) of sports-related traumatic brain injury (TBI) …

Several lines of evidence suggest aberrant immune response in schizophrenia, including
elevated levels of cytokines. These cytokines are thought to be produced by activated …

Compton imaging or Compton camera imaging has been studied well, but its advantages in
nuclear medicine and molecular imaging have not been demonstrated yet. Therefore, the …

A high-resolution positron emission tomography (PET) scanner, dedicated to brain studies,
was developed and its performance was evaluated. A four-layer depth of interaction detector …

Modern high-resolution PET is now more than ever in need of scrutiny into the nature and
limitations of the imaging modality itself as well as image reconstruction techniques. In this …

With continuing improvements in spatial resolution of positron emission tomography (PET)
scanners, small patient movements during PET imaging become a significant source of …

Imaging the brain distribution of translocator protein (TSPO), a putative biomarker for glial
cell activation and neuroinflammation, may inform management of individuals infected with …

List-mode processing provides an efficient way to deal with sparse projections in iterative
image reconstruction for emission tomography. An issue often reported is the tremendous …
