As mass COVID-19 vaccination is underway, radiologists are encountering transient FDG
uptake in normal or enlarged axillary, supraclavicular, and cervical lymph nodes after …

Methods: Images were simulated using an analytic projector acting on the mathematic cardiac
torso computer phantom. Perfect scatter rejection was assumed. Lesion detection accu …

For the 2011 FDA approved Parkinson's Disease (PD) SPECT imaging agent I-123 labeled
DaTscan, the volume of interest (VOI) is the interior portion of the brain. However imaging of …

BACKGROUND The use of 5‐fluorouracil (5‐FU) and levamisole in patients with Stage III
adenocarcinoma of the colon has now become standard. There have been several reports of a …

Purpose: Head motion during PET brain imaging can cause significant degradation of
image quality. Several authors have proposed ways to compensate for PET brain motion to …

Purpose: Studies have suggested using TI‐201 brain SPECT to differentiate lymphoma from
infectious processes and to determine the timing for biopsy or empirical therapy for patients …

Background The aim of this research was to asses perfusion-defect detection-accuracy by
human observers as a function of reduced-counts for 3D Gaussian post-reconstruction filtering …

Image artifacts from variable self-attenuation are recognized as major sources of diagnostic
uncertainty in SPECT. For myocardial perfusion studies, an attenuation map is often …

With increasing availability of multimodality imaging systems, high-resolution anatomical
images can be used to guide the reconstruction of emission tomography studies. By measuring …
