Abstract This study aimed to investigate the predictive efficacy of positron emission tomography/computed tomography (PET/CT) and magnetic resonance imaging (MRI) for pathological response advanced breast cancer neoadjuvant chemotherapy (NAC). The PET/MRI image deep learning model was introduced compared with conventional methods. PET/CT MRI parameters were evaluated before after first NAC cycle in patients [n = 56; all women; median age, 49 (range 26–66) years]. maximum standardized uptake...

The aim of this retrospective study was to determine whether glucose metabolism assessed by fluorine-18 fluorodeoxyglucose (F-FDG) PET/computed tomography (CT) provides prognostic information independent established factors in patients with gastric lymphoma.We reviewed the medical records 86 retrospectively (men, 42; women, 44; mean age 58±13 years) pathologically proven lymphoma (34 mucosa-associated lymphoid tissue and 52 aggressive non-Hodgkin's lymphoma). They underwent F-FDG PET/CT as...
Aim The aim of this retrospective study was to determine whether glucose metabolism assessed by using Fluorine-18 (F-18) fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) provides prognostic information independent established factors in patients with Ewing sarcoma. Methods We retrospectively reviewed the medical records 34 (men, 19; women, 15; mean age, 14.5 ± 9.7 years) pathologically proven They had undergone F-18 FDG PET/CT as part a pretreatment workup...
Abstract Background The purpose of this study was to evaluate both the biodistribution and safety 64 Cu-1,4,7-triazacyclononane-1,4,7-triacetic acid (NOTA)-Trastuzumab, a novel Cu-labeled positron emission tomography (PET) tracer for human epidermal growth factor receptor 2 (HER2) in patients with breast cancer. Methods PET images at 1, 24, 48 h after 296 MBq Cu-NOTA-Trastuzumab injection were obtained from seven Both primary tumors’ metastatic lesions’ maximum standardized uptake value (SUV...
An evolutionary optimization process involving a genetic algorithm and combinatorial chemistry was employed for the development of green phosphors which are suitable tricolor white-light-emitting diodes. To accomplish high luminescent efficiency at 400 nm excitation, we screened seven-cation oxide system including Tb, Gd, Ce, Mg, Si, Al, B. The combination enhanced searching when applied phosphor screening. As result, optimized composition Tb0.01Gd0.02Ce0.04B0.1Si0.83Oδ, luminance this...

Abstract 123 I‐FP‐CIT and 18 F‐FP‐CIT are radiotracers which widely used to diagnose Parkinson's disease (PD). However, our knowledge, no studies date have made head‐to‐head comparisons between F‐FP‐CIT. Therefore, in this study, SPECT/CT was compared with PET/CT the same cohort of subjects. Patients PD essential tremor (ET) underwent PET/CT. Visual semiquantitative analyses were conducted. The specific binding ratio (SBR) putamen caudate (PCR) subjects who analysis showed that striatal...
As a new beta amyloid (Aβ) positron emission tomography (PET) tracer, 18F-FC119S has shown higher cortical uptake in patients with Alzheimer's disease (AD) than that healthy control subjects without adverse effects previous preliminary study. The aim of this study was to compare PET and 11C-PiB (HC) subjects, mild cognitive impairment (MCI) patients, AD patients. A total 48 including 28 HC 10 MCI underwent static (30 minutes after intravenous [i.v.] injection) (40 i.v. on the same day. Both...
Purpose: Zirconium-89 (t1/2=78.41 hours) is an ideal metallic radioisotope for immuno–positron emission tomography (PET), given that its physical half-life closely matches the biological of monoclonal antibodies. In this study, authors measured spatial resolution and image quality Zr-89 PET compared results against those obtained using F-18 PET, which widely regarded as gold standard comparison imaging characteristics. Materials Methods: The qualities were on Siemens Biograph Truepoint TrueV...
Two new bicyclic arginine-glycine-aspartic acid (RGD) peptides, c(RGD-ACP-K) (1a) and c(RGD-ACH-K) (1b), incorporating the aminocyclopentane (ACP) aminocyclohexane (ACH) carboxylic acids, respectively, were synthesized by grafting aminocycloalkane acids onto tetra-peptide RGDK sequence. These peptides their conjugates with DO3A (1,4,7,10-tetraazacyclododecane-1,4,7-trisacetic acid) (2a–b) exhibit high affinity toward U87MG glioblastoma cells. Their is greater than that exhibited c(RGDyK)....
To propose a personalized therapeutic approach in osteosarcoma treatment, we assessed whether sequential [18F]FDG PET/CT (PET/CT) could predict the outcome of patients with extremities after one cycle and two cycles neoadjuvant chemotherapy.A total 73 AJCC stage II extremity treated 2 chemotherapy, surgery, adjuvant chemotherapy were retrospectively analyzed this study. All underwent before (PET0), 1 (PET1), completion (PET2), respectively. Maximum standardized uptake value (SUVmax)...

To obtain an additional pharmacological agent for the diagnosis of inflammation, we investigated medical use (89)Zr-oxalate as a positron emission tomography (PET) probe in vivo imaging inflammation and compared its efficacy to that 2-deoxy-2-[(18)F]fluoro-d-glucose ([(18)F]FDG) sodium [(18)F]fluoride. exhibited observable higher uptake macrophage cell line than tumor cells. The inflammatory lesions tumors were clearly visualized by PET autoradiography using (89)Zr-oxalate. Compared...
Materials with differing surfaces have been developed for clinical implant therapy in dentistry and orthopedics. This study was designed to evaluate bone response titanium alloy containing Ti-32Nb-5Zr nanostructure, anodic oxidation, heat treatment, ibandronate coating. Rats were randomly assigned two groups implantation of (untreated) as the control group coated experimental group. Then, implants inserted both tibiae rats four weeks. After implantation, interface, trabecular microstructure,...
