BACKGROUND AND AIMS  The role of three-dimensional positron emission tomography/computed tomography (3 D PET/CT) in esophageal tumors that move with respiration and have potential for significant mucosal inflammation is unclear. The aim of this study was to determine the correlation between gross tumor volumes derived from 3 D PET/CT and endoscopically placed fiducial markers. METHODS  This w...

BACKGROUND While non-rigid fusion is by definition expected to alter the information of positron emission tomography (PET) data, we assessed whether rigid transformation also influences metabolic tumor volume (MTV) determination. METHODS The PET/computed tomography (CT) data of 28 solid pulmonary lesions of 20 tumor patients examined with 18 F-Fluordeoxyglucose (FDG) was retrospectively analy...

The moth-flame optimization (MFO) algorithm is an effective nature-inspired based on the chemical effect of light moths as animal with bilateral symmetry. Although it widely used to solve different problems, its movement strategy affects convergence and balance between exploration exploitation when dealing complex problems. Since strategies significantly affect performance algorithms, use multi...

Peritonitis is a serious complication in patients on peritoneal dialysis. We examined the efficacy of MTV therapy [first 7 days: meropenem 0.5 g intravenously (IV) twice daily, plus tobramycin 15 mg intraperitoneally (IP) in every dialysis bag; next 7 days: meropenem 0.5 g IV twice daily, plus vancomycin 8 mg/kg IP in every bag after a 1-g loading dose] on peritonitis in patients undergoing con...

Obesity is associated with differences in satiety, gastric emptying (GE), gastric volume, and psychological traits. Exenatide, a short-acting glucagon-like peptide 1 (GLP-1) receptor agonist, is associated with variable weight loss. We compared the effects of exenatide, 5 μg, and placebo SQ, twice daily for 30 days on GE of solids and liquids (scintigraphy), satiety (ad libitum buffet meal), sa...

UNLABELLED Modern multidisciplinary therapy for colorectal liver metastases (CRLM) is associated with significant morbidity and must be adapted to the patient's relative risk. The tools currently available to risk-stratify patients are limited. This study assessed the prognostic utility of metabolic measurements derived from(18)F-FDG PET compared with previously proposed prognostic scoring syst...

PURPOSE To explore the values of sequential (18)F-FDG PET/CT scanning in patients with non-surgical esophageal squamous cell carcinoma (ESCC) who received concurrent chemoradiotherapy (CCRT). METHODS Twenty-eight patients with pathologically confirmed stage I-IV ESCC and who received definitive CCRT were prospectively enrolled into this trial. The (18)F-FDG PET/CT scans were performed four ti...

This paper aimed to evaluate the prognostic value of maximum standardized uptake value (SUVmax) and metabolic tumor volume (MTV) of the primary tumor on (18)F-FDG PET/CT scan in early stage non-small cell cancer (NSCLC) patients without lymph node (LN) metastasis. In the experiment, eighty NSCLC patients pathologically staged as T1N0 or T2N0 were included (M:F=50:30; mean age, 64.8 years). All ...

Mammary tumorigenesis and mammary tumor trans plantation immunogenicity were examined in breeding fe males of 2 syngeneic sublines of the C3H strain: in mammary tumor virus (MTV) plus nodule-inducing virusinfected C3H/Sed mice; and in MTV-free, nodule-inducing virus-infected C3Hf/Sed mice. Ninety-seven % of the C3H mice (29 of 30) developed mammary tumors at an average age of 280 days. Of 43 di...

PURPOSE The purpose of this study was to evaluate the impact of tumor motion on maximum standardized uptake value (SUVmax) and metabolic tumor volume (MTV) measurements in both 3-dimensional and respiratory-correlated, 4-dimensional positron emission tomography (PET) imaging. We also evaluated the effect of implementing different attenuation correction methods in 4-dimensional PET image reconst...
