Partial-volume effects (PVEs) arise from the limited spatial resolution of PET and SPECT imaging systems, causing the systematic underestimation of activity concentration in structures that may hold ...

RECIST was developed in 2000 by the National Cancer Institute, European Organization for Research and Treatment of Cancer, and National Cancer Institute of Canada, with revision to RECIST 1.1 in 2009 ...

Dr. Bernd Pichler is a distinguished pioneer in preclinical and translational imaging, renowned for his groundbreaking work in multimodal imaging and imaging tracer development. As chair of the ...

Fibroblast activation protein (FAP) has become an attractive target for diagnosis and therapy, and a series of FAP inhibitor (FAPI)–based radiotracers has been developed and had excellent performance ...

Protein tyrosine kinase-7 (PTK7), a member of receptor tyrosine kinase superfamily initially identified as colon carcinoma kinase-4, is highly expressed in various human malignancies. Its expression ...

When pregnancy is discovered during or after a diagnostic examination, the physician or the patient may request an estimate of the radiation dose received by the fetus as per guidelines and standard ...

Cerenkov luminescence imaging (CLI) provides a convenient approach to image the in vivo distribution of radiopharmaceuticals using optical instruments. It has attracted much attention and been widely ...

Fibroblast activation protein (FAP), expressed in the tumor microenvironment of a variety of cancers, has become a target of novel PET tracers. The purpose of this report is to evaluate the imaging ...

Evidence supporting the hypothesis that reduced cerebrospinal fluid (CSF) clearance is involved in the pathophysiology of Alzheimer disease (AD) comes primarily from rodent models. However, unlike ...

The advent of PET ligands that bind tau pathology has enabled the quantification and visualization of tau pathology in aging and in Alzheimer disease (AD). There is strong evidence from ...

Imaging of dopaminergic transmission in neurodegenerative disorders such as Parkinson disease (PD) or dementia with Lewy bodies plays a major role in clinical practice and in clinical research. We ...

The immune-fibrosis axis plays a critical role in cardiac remodeling after acute myocardial infarction. Imaging approaches to monitor temporal inflammation and fibroblast activation in mice have seen ...
