Until recently, the most widely used methods for image reconstruction were direct analytic
techniques. Iterative techniques, although computationally much more intensive, produce …

In tomographic medical imaging (PET, SPECT, CT), differences in data acquisition and
organization are a major hurdle for the development of tomographic reconstruction software …

Several factors have to be considered for implementing an accurate attenuation-correction
(AC) method in a combined MR-PET scanner. In this work, some of these challenges were …

Selective serotonin reuptake inhibitors (SSRIs) are widely used for treating neuropsychiatric
disorders. However, the exact mechanism of action and why effects can take several weeks …

We have developed a positron emission tomography (PET) and magnetic resonance
imaging (MRI) fusion system for the molecular‐genetic imaging (MGI) of the in vivo human …

Iterative methods for 3D image reconstruction have the potential to improve image quality
over conventional filtered back projection (FBP) in X-ray computed tomography (CT) …

Head motion is difficult to avoid in long PET studies, degrading the image quality and
offsetting the benefit of using a high-resolution scanner. As a potential solution in an …

Gamma-aminobutyric acid (GABA) is the main inhibitory neurotransmitter in the human brain
and plays a key role in several brain functions and neuropsychiatric disorders such as …

Background Inflammation is hypothesized to be a key event in the growth of sporadic
vestibular schwannoma (VS). In this study we sought to investigate the relationship between …
