: To determine the potential value of (13)N-ammonia positron emission tomography (PET)/computed tomography (CT) myocardial perfusion imaging (MPI) for detection of myocardial perfusion changes at early stage induced by radiation damage. METHODS: Thirty-six Beagle dogs were randomly divided into the control (n = 18) or the irradiation groups (n = 18). The irradiation group underwent local irradiation to the left ventricular anterior cardiac wall with a single dose of 20 Gy, whereas the control group received sham irradiation...

Currently, several non-invasive modalities, including MRI and PET, are being investigated to identify early intestinal inflammation, longitudinally monitor disease status, or detect dysplastic changes in patients with inflammatory bowel disease (IBD). Here, we assess the applicability and utility of multispectral optoacoustic tomography (MSOT) in evaluating the presence and severity of colitis. Mice with bacterial colitis demonstrated a temporally associated increase in mesenteric and colonic vascularity with an increase in mean signal intensity of oxygenated hemoglobin (p=0...

: Estrogen receptors (ER) are targets for endocrine treatment of estrogen-dependent cancers. The ER consists of 2 isoforms, ERα and ERβ, which have distinct biological functions. While activation of ERα stimulates cell proliferation and cell survival, ERβ promotes apoptosis. Positron emission tomography (PET) of ERα and ERβ levels could provide more insight in response to hormonal treatment. 16α-(18)F-Fluoro-17β-estradiol ((18)F-FES) is a PET tracer for ER with relative selectivity for ERα...

PURPOSE: Several studies outlined the sensitivity of (68)Ga-labeled PET tracers against the prostate-specific membrane antigen (PSMA) for localization of relapsed prostate cancer in patients with renewed increase in the prostate-specific antigen (PSA), commonly referred to as biochemical recurrence. Labeling of PSMA tracers with (18)F offers numerous advantages, including improved image resolution, longer half-life and increased production yields. The aim of this study was to assess the PSA-stratified performance of the (18)F-labeled PSMA tracer (18)F-DCFPyL and the (68)Ga-labeled reference (68)Ga-PSMA-HBED-CC...

: (18)F-AV-1451 is currently the most widely used of several experimental tau PET tracers. The objective of this study was to evaluate (18)F-AV-1451 binding with full kinetic analysis using a metabolite corrected arterial input function, and to compare parameters derived from kinetic analysis with standardized uptake value ratio (SUVR) calculated over different imaging time intervals. METHODS: (18)F-AV-1451 PET brain imaging was completed in 16 subjects: 4 young healthy volunteers (YHV), 4 aged healthy volunteers (AHV) and 8 Alzheimer's disease subjects (AD)...

: One of the major design considerations for a drug is its pharmacokinetics in the blood. A drug with short half-life in the blood is less available at a target organ. Such a limitation dictates treatment with either high doses or more frequent doses, both of which may increase the likelihood of undesirable side effects. To address the need for additional methods to improve the blood half-life of drugs and molecular imaging agents, we developed an "add-on" molecule that contains three groups: (i) truncated Evans Blue (EB) dye molecule that binds to albumin with low micromolar affinity and provides prolonged half-life in the blood; (ii) a metal chelate that allows radiolabeling for imaging and radiotherapy; and (iii) a maleimide for easy conjugation to drug molecules...

The current review focuses on recent human FDG-PET studies in Parkinson's disease. First, an overview is given of the current analytical approaches to metabolic brain imaging data. Next, we discuss how FDG-PET studies have advanced understanding of the relation between distinct brain regions and associated symptoms in Parkinson's disease, including cognitive decline. In addition, the value of FDG-PET studies in differential diagnosis, identifying prodromal patients and the evaluation of treatment effects are reviewed...

The concept of the ischemic penumbra was formulated based on animal experiments showing functional impairment and electrophysiological disturbances with decreasing flow to the brain below defined values (the threshold for function) and irreversible tissue damage with blood supply further decreased (the threshold for infarction). The perfusion range between these thresholds was termed "penumbra", and restitution of flow above the functional threshold was able to reverse the deficits without permanent damage...

Interim and end-of-treatment PET/CT have become central to the evaluation of Hodgkin's and non-Hodgkin's lymphoma. This review article seeks to aid clinical decision-making by providing an overview of available data on the diagnostic and prognostic value of PET/CT imaging for response assessment and pre-transplant evaluation in lymphoma. The relative strengths and limitations of these techniques in various disease subtypes and clinical scenarios are explored, along with their current standards for reporting and latest developments...

: Molecular imaging of cell death may provide a detailed readout of the cellular response to novel therapies and prognostic information on tumor treatment efficacy assisting in the design of individualized therapy. We compared the predictive power of cell death imaging using (99m)Tc-duramycin to current gold standard (18)F-FDG for treatment response evaluation after targeted therapy. METHODS: Early therapy response evaluation was assessed by (99m)Tc-duramycin SPECT and (18)F-FDG PET imaging in treatment-sensitive COLO205 and treatment-resistant HT29 human colorectal cancer xenografts 24 hours after a single dose of conatumumab or IgG1 control...

: For positron emission tomography (PET) imaging of 18-kDa translocator protein (TSPO), a biomarker of neuroinflammation, most second-generation radioligands are sensitive to the single nucleotide polymorphism rs6971; however this is probably not the case for the prototypical agent (11)C-PK 11195, which has a relatively lower signal-to-noise ratio. We recently found that (11)C-ER176, a new analog of (11)C-(R)-PK 11195, showed little sensitivity to rs6971 when tested in vitro and had high specific binding in monkey brain...

: Fluorine-18-labeled 1-amino-3-fluorocyclobutane-1-carboxylic acid ((18)F-Fluciclovine) is a leucine analog radiotracer that depicts amino acid transport into cells. (18)F-Fluciclovine PET/CT visualizes malignancy including prostate cancer, invasive ductal breast cancer (IDC) and invasive lobular breast cancers (ILC). It has not been shown whether changes in (18)F-Fluciclovine avidity reflect changes in tumor burden resulting from treatment. This prospective clinical trial evaluates changes in (18)F-Fluciclovine-avidity compared to breast cancer therapy response, as determined by residual tumor burden on pathology...

: (123)I-FP-CIT SPECT can visualise and quantify striatal dopamine transporter (DAT) binding in vivo. In addition, (123)I-FP-CIT has modest affinity for the serotonin transporter (SERT), predominantly represented in extrastriatal binding. Based on previous imaging studies that have suggested more pronounced degeneration of other monoaminergic systems in multiple system atrophy (MSA) and progressive supranuclear palsy (PSP) than in Parkinson's disease (PD), we hypothesised that, in addition to striatal DAT binding, there would be differences in extrastriatal (123)I-FP-CIT SPECT binding to SERT between MSA, PSP and PD...

PURPOSE: This study compared the in vivo imaging characteristics of tau positron emission tomography (PET) ligands (18) F-THK-5351 and (18)F-THK-5317 in the context of Alzheimer's disease (AD). Additionally, reference tissue distribution volume ratio (DVR) estimation methods and standard uptake value ratio (SUVR) timing windows were evaluated to determine the optimal strategy for specific binding quantification. METHODS: Twenty-eight subjects (mean age 71±7yrs) underwent either dynamic 90-minute (18)F-THK-5317 or (18)F-THK-5351 PET scans...

RATIONALE: Since the discovery of the HTT gene in 1993, numerous animal models have been developed to study the progression of Huntington's disease, as well as to evaluate potential new therapeutics. In the present study we used small animal positron emission tomography (PET) to characterize the expression of molecular targets in the recently reported HD animal model, the zQ175 mouse model. METHODS: Male heterozygous zQ175 (Htttm1Mfc/190JChdi, CHDI-81003003) and wild type (WT, C57BL/6J) animals were imaged with the dopamine D2-receptor radioligand [(11)C]raclopride, the PDE10A radioligand [(18)F]MNI-659, the dopamine D1-receptor radioligand [(11)C]NNC 112 and the 5-HT2A radioligand [(11)C]MDL 100907 at 6 and 9 months of age...
