A new simple and reliable method for rapid and selective extraction and determination of trace levels of Zn(II) ion is developed. Zn(II) ions are adsorbed quantitatively during passage of aqueous samples through PET-AA/AAm nano fiber modified. Almost all matrix elements were found to pass through the nano fiber to drain. Modified Poly (ethylene terephthalate)-grafted-Acrylic acid/Acryl amide Na...

The indiscriminate utilization of nondegradable polyethylene terephthalate (PET)-based products has triggered serious environmental pollution that to be resolved vigorously. A simple synthesis N-doped carbon nanotubes from recycled PET (NCNTsr-PET) was developed by a nitric acid-assisted hydrothermal method. Experimental results and theoretical calculations show the intrinsic defects in CNTsr-P...

1. Substantial number of patients in the study underwent postoperative follow-up with PET alone instead of PET/CT. PET/CT was installed in our institution in 2009 and PET (without CT component) was used before 2009. The authors misunderstood that all the patients in this study underwent PET/CT, but recently realized that this was incorrect. PET alone may be inferior to PET/CT for detection of s...

PET/CT is an effective tool for the diagnosis, staging and restaging of cancer patients. It combines the complementary information of functional PET images and anatomical CT images in one imaging session. Conventional stand-alone PET has been replaced by PET/CT for improved patient comfort, patient throughput, and most importantly the proven clinical outcome of PET/CT over that of PET and that ...

We have investigated improvements to PET-MR image registration offered by PET-CT scanning. Ten subjects with suspected soft-tissue sarcomas were scanned with an in-line PET-CT and a clinical MR scanner. PET to CT, CT to MR and PET to MR image registrations were performed using a rigid-body external marker technique and rigid and non-rigid voxel-similarity algorithms. PET-MR registration was als...

BACKGROUND Cystic lymph node metastasis (CLNM) is commonly found in human papillomavirus (HPV)-associated tonsillar squamous cell carcinoma (SCC). The aim of this study was to compare the accuracy in detecting cystic lymph node metastasis from tonsillar SCC between contrast-enhanced CT, ¹⁸F- fluorodeoxyglucose-positron emission tomography (FDG-PET), non-enhanced ¹⁸F-FDG-PET/CT, and contrast-enh...

nowadays polymer nanocomposites have introduced as a new class of food packaging materials due to their enhanced mechanical, thermal, and barrier properties. in this study pet nano composites were prepared by melt blending of poly (ethylene terephthalate) pellets and mica nanoparticles. the morphology of pet/mica nanocomposites was characterized by x-ray diffraction and transmission electron mi...

PURPOSE The aim of this study was to compare detection, lesion conspicuity and reader confidence of F-fluorodeoxyglucose (F-FDG)-PET/MR and F-FDG-PET/computed tomography (CT) in patients with F-FDG avid bone metastases. MATERIALS AND METHODS In this prospective study, a total of 30 PET/CT and PET/MRI data sets were performed in 24 patients. Each examination was evaluated for the presence of P...

Attenuation correction (AC) is essential for the generation of artifact-free and quantitatively accurate positron emission tomography (PET) images. PET AC based on computed (CT) frequently results in artifacts attenuation-corrected images, these mainly originate from CT PET-CT mismatches. The combined with a magnetic resonance imaging (MRI) scanner (PET/MRI) more complex than PET/CT, given that...

PURPOSE We compared the accuracy of (18)F-Choline-PET/MRI with that of multiparametric MRI (mMRI), (18)F-Choline-PET/CT, (18)F-Fluoride-PET/CT, and contrast-enhanced CT (CeCT) in detecting relapse in patients with suspected relapse of prostate cancer (PC) after external beam radiotherapy (EBRT). We assessed the association between standard uptake value (SUV) and apparent diffusion coefficient (...
