Cervical cancer recently has become more common among younger women in Japan. Diagnosing early-stage cancer is straightforward using cervical cytodiagnosis and histological diagnosis. However, postmenopausal endophytic cervical cancer and skip lesions in cervical adenocarcinoma are difficult to detect. We compared the maximum standardized uptake value (SUVmax) of 18F-fluorodeoxy-glucose positro...
Backgrounds/Aims Diagnosis and staging of hepatocellular carcinoma (HCC) is critical because of the variety of treatment methods and prognosis. [18F]fludeoxyglucose-positron emission tomography/computed tomography ([18F]FDG-PET/CT) has been suggested as a diagnostic modality in HCC. The purpose of this study is to evaluate the accuracy of FDG-PET for staging of HCC after surgical resection and ...
This study was designed to elucidate the predictive usefulness of the response evaluation criteria in solid tumors (RECIST), a volume response (VR; a > 50% reduction in the tumor volume) and the post-neoadjuvant therapy maximum standardized uptake value (post-SUVmax) in patients with non-small cell lung cancer (NSCLC) after neoadjuvant therapy. Between December 2006 and June 2012, 33 patients w...
BACKGROUND/AIMS We sought to investigate the roles of maximum standardized uptake value (SUVmax) and serum carbohydrate antigen 19-9 (CA 19-9) in predicting the histopathological features of periampullary tumors. MATERIALS AND METHODS Thirty-four patients with histologically confirmed periampullary tumors were classified into two groups, according to the localizations of their tumors (ampulla...
OBJECTIVE Application of distinct positron emission tomography (PET) scan reconstruction algorithms can lead to statistically significant differences in measuring lesion functional properties. We looked at the influence of two-dimensional filtered back projection (2D FBP), two-dimensional ordered subset expectation maximization (2D OSEM), three-dimensional ordered subset expectation maximizatio...
The goal of this study was to identify associations between positron emission tomography/computed tomography (PET/CT) maximum standardized uptake value (SUVmax) in patients presenting with head and neck squamous cell carcinoma (SCC) with tumor site, size, histologic differentiation, smoking, and diabetes. Charts of patients with oropharyngeal and laryngeal SCC who underwent 18F-fluorodeoxygluco...
UNLABELLED We combined (18)F-FDG PET and CT enterography in a single examination and compared the level of (18)F-FDG uptake measured by maximal standardized uptake value (SUVmax) with the CT enterography patterns of disease activity found in patients with Crohn disease (CD). METHODS Twenty-eight patients (mean age, 37.5 y; 11 male and 17 female) suspected of having active CD underwent PET/CT ...
INTRODUCTION The purpose of this study was to evaluate the use of (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) to identify the presence of cervical lymph nodes metastases and extracapsular spread with histologic correlations in head and neck squamous cell carcinoma. METHODS The medical records of 54 patients who underwent (18)F-FDG PET/CT for he...
PURPOSE Evidence regarding the usefulness of (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) in predicting the prognosis of non-small cell lung cancer is increasing. However, data on small cell lung cancer (SCLC) are scarce. The aim of this study was to evaluate the prognostic value of metabolic parameters measured using (18)F-FDG PET/CT in patients ...
Purpose: To evaluate the dependency of the sensitivity of [C]choline positron emission tomography/ computed tomography (PET/CT) for detecting and localizing primary prostate cancer (PCa) on tumor configuration in the histologic specimen. Experimental Design: Forty-three patients with biopsy-proven PCa were included. They underwent radical prostatectomy within 31 days after [C]choline PET/CT. Th...
