The objective of this study was to investigate the value of parameters assessed with F18-FDG PET/CT in predicting recurrence-free survival (RFS) and disease-specific survival (DSS) in patients with cancer of nasal cavity and paranasal sinus. Thirty-eight patients with cancer of nasal cavity (n = 14) and paranasal sinus (n = 24) who underwent PET/CT prior to curative treatment were enrolled. A volume of interest was placed on PET/CT images covering the entire tumor volume, and the maximum SUV (SUVmax), the mean SUV (SUVmean), and volumetric parameters of metabolic tumor volume (MTV) and total lesion glycolysis (TLG) were measured using thresholds of 40 % of SUVmax...

We evaluated the role of metabolic parameters in the prediction of disease recurrence in operable invasive ductal breast cancer patients treated with neoadjuvant chemotherapy (NAC).We retrospectively evaluated 139 female patients (mean age, 46.5 years; range: 27-72 years) with invasive ductal breast cancer, treated with NAC followed by surgery. All patients underwent F-fluorodeoxyglucose positron emission tomography/computed tomography and magnetic resonance imaging at baseline and after completion of NAC before surgery...

Thirty-six porphyrin based metal-organic frameworks (MOFs) with composition of (M3O)2(TCPP-M)3 and M3O trigonal SBUs of various metals, Mg3O, Mn3O, Co3O, Ni3O, and Fe3O including mixed-metal SBUs, MnxFe3-xO, NixFe3-xO, CoxNi3-xO, MnxCo3-xO, MnxMg3-xO, and MnxNi3-xO were synthesized and characterized. These multivariate MOFs (MTV-MOFs) were examined by X-ray photoelectron spectroscopy (XPS), ultraviolet-visible diffuse reflectance spectra (UV-vis DRS) and, for the first time, their metal spatial arrangement deciphered and found to exist in the form of either domains or well-mixed...

INTRODUCTION: Fluorine-18 fluorodexyglucose positron emission tomography with CT attenuation correction (18F-FDG PET/CT) is useful in the detection and enumeration of focal lesions and in semi-quantitative characterization of metabolic activity (glycolytic phenotype) by calculation of glucose uptake. Total lesion glycolysis (TLG) and metabolic tumor volume (MTV) have the potential to improve the value of this approach and enhance the prognostic value of disease burden measures. This study aims to determine whether TLG and MTV are associated with PFS and OS, and whether they improve risk assessments such as ISS stage and GEP70 risk...

PURPOSE: Positron emission tomography (PET)-based radiomics has been used to non-invasively quantify the metabolic tumor phenotypes; however, little is known about the relationship between these phenotypes and underlying somatic mutations. This study assessed the association and predictive power of (18)F-FDG-PET-based radiomic features for somatic mutations in non-small cell lung cancer (NSCLC) patients. METHODS: 348 NSCLC patients underwent diagnostic (18)F-FDG-PET/CT scans and were tested for genetic mutations...

BACKGROUND: The nucleoside analog 3'-deoxy-3'-(18)F-fluorothymidine (FLT) has been investigated for evaluating tumor proliferating activity in brain tumors. We evaluated FLT uptake heterogeneity using textural features from the histogram analysis in patients with newly diagnosed gliomas and examined correlation of the results with proliferative activity and patient prognosis, in comparison with the conventional PET parameters. METHODS: FLT PET was investigated in 37 patients with newly diagnosed gliomas...

OBJECTIVE: This prospective study compared the value of pretreatment 4'-[methyl-(11)C]-thiothymidine ((11)C-4DST) volumetric parameters and those of 2-deoxy-2-[18F] fluoro-D-glucose ((18)F-FDG) in predicting the clinical outcome in patients with head and neck squamous cell carcinoma (HNSCC). METHODS: Fifty patients with HNSCC underwent (11)C-4DST PET/CT and (18)F-FDG PET/CT prior to anticancer therapy. (18)F-FDG metabolic tumor volume ((18)F-FDG MTV) and total lesion glycolysis (TLG) were calculated from (18)F-FDG PET, and (11)C-4DST MTV and total lesion proliferation (TLP) were calculated from (11)C-4DST PET...

The myelin g-ratio is defined as the ratio of the inner to the outer diameter of the myelin sheath. This ratio provides a measure of the myelin thickness that complements axon morphology (diameter and density) with high specificity for assessment of demyelination in diseases such as multiple sclerosis. Previous work has shown that an aggregate g-ratio map can be computed using a formula that combines axon and myelin density measured with quantitative MRI. In this work, we computed g-ratio weighted maps in the cervical spinal cord of nine healthy subjects...

PURPOSE: To determine whether higher pre-treatment metabolic tumor volume (tMTV-pre) is associated with worse overall survival (OS) in patients with inoperable NSCLC treated with definitive chemoradiation (CRT). METHODS: This is a secondary analysis of the American College of Radiology Imaging Network (ACRIN) 6668/Radiation Therapy Oncology Group 0235 trial. Pre-treatment PET scans were performed on ACRIN-qualified scanners. Computer-aided MTV measurement was performed using RT_Image...

BACKGROUND: Approximately 8-17 % of patients with von Hippel-Lindau (VHL) syndrome develop pancreatic neuroendocrine tumors (PNETs), with 11-20 % developing metastases. Tumor grade is predictive of prognosis. OBJECTIVE: The aim of this study was to determine if preoperative metabolic tumor volume (MTV) and total lesion glycolysis (TLG) were associated with metastatic disease and tumor grade. METHODS: Sixty-two patients with VHL-associated PNETs prospectively underwent (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT)...

PURPOSE: This retrospective study was done to examine whether the heterogeneity in primary tumour F-18-fluorodeoxyglucose ((18)F-FDG) distribution can predict tumour response and prognosis of patients with esophageal cancer treated by chemoradiotherapy (CRT). METHODS: The enrolled 52 patients with esophageal cancer underwent (18)F-FDG-PET/CT studies before CRT. SUVmax, SUVmean, metabolic tumour volume (MTV, SUV ≥ 2.5), total lesion glycolysis (TLG) and six heterogeneity parameters assessed by texture analysis were obtained...

OBJECTIVE/HYPOTHESIS: We previously reported that the metabolic tumor volume (MTV) of a primary tumor was an independent prognostic factor for survival in laryngeal carcinoma treated by radiotherapy (RT)-based protocol. The purpose of this study was to evaluate the difference in survival outcomes between surgery-based and RT-based treatment in patients with a MTV laryngeal cancer. STUDY DESIGN: An individual retrospective cohort study. METHODS: We reviewed the records of 63 patients with laryngeal cancer showing a primary tumor with a high MTV value (≥ 4...

PURPOSE: To describe the evolution and to assess the predictive value of metabolic parameters with different SUV threshold segmentations calculated from two 18F-FDG-PET/CT, one prior to and the other one during concomitant chemoradiation therapy (CCRT), for locally-advanced cervical cancer (LACC). MATERIAL AND METHODS: 53 patients treated for LACC by CCRT underwent FDG-PET/CT before treatment (PET1) and another one at 40Gy (PET2). The PET analyzed parameters were: maximum standardized uptake value (SUVmax), metabolic tumor volume (MTV), and total lesion glycolysis (TLG)...

AIM: A small number of studies evaluated the detection rate of lesions from bladder carcinoma (BC) of 18 F-FDG PET/CT in the restaging process. However, the prognostic role of FDG PET/CT still remains unclear. The aim of the present study was to evaluate the accuracy, the effect upon treatment decision, and the prognostic value of FDG PET/CT in patients with suspected recurrent BC. MATERIALS AND METHODS: Forty-one patients affected by BC underwent FDG PET/CT for restaging purpose...

This study investigated the prognostic value of metabolic parameters determined by 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) in patients with stage III gastric cancer. Patients with pre-operative PET/CT and confirmed stage III after curative surgical resection were retrospectively enrolled. Parameters evaluated from pre-operative PET/CTwere maximum standardized uptake value (SUVmax) and peak SUV (SUVpeak) of primary tumor, SUVmax or SUVpeak of tumor to liver ratio (TLRmax and TLRpeak)...

INTRODUCTION: PET/CT plays an important role in cancer diagnosis. Recently, novel metabolic parameters in PET/CT such as metabolic tumor volume (MTV) and total lesion glycolysis (TLG) have been reported to be diagnostic and prognostic biomarkers of various cancers. We evaluated the diagnostic value of these metabolic parameters in colorectal cancer (CRC). METHODS: The study included 138 patients who underwent surgical resection of CRCs between August 2012 and March 2014...
