PURPOSE The aim of this study was to examine abnormalities of the central nervous system in patients with chronic pain who were diagnosed with complex regional pain syndrome (CRPS). MATERIALS AND METHODS Brain activity was assessed using (18)F-fluorodeoxyglucose positron emission tomography. The data collected from 18 patients were compared with data(More)
PURPOSE We conducted a pilot study to prospectively evaluate the efficacy of PET/CT with (11)C-choline (choline PET/CT) for primary diagnosis and staging of urothelial carcinoma of the upper urinary tract (UUT-UC). METHODS Enrolled in this study were 16 patients (9 men, 7 women; age range 51 - 83 years, mean ± SD 69 ± 10.8 years) with suspected UUT-UC.(More)
UNLABELLED Earlier investigations showed that N-isopropyl-p-123I-iodoamphetamine SPECT (123I-IMP SPECT) is useful for the diagnosis of uveal malignant melanoma, whereas the feasibility and usefulness of 18F-FDG PET in uveal malignant melanoma have not yet been established. We compared the usefulness of 123I-IMP SPECT and 18F-FDG PET for the detection of(More)
OBJECTIVE We assessed the performance of 37 MBq I-123 as a diagnostic imaging agent in patients with differentiated thyroid cancer using comparisons with their corresponding high-dose post-treatment I-131 scans. METHODS We reviewed diagnostic I-123 whole-body scans and post-treatment I-131 scans of 69 patients who underwent I-131 therapy for(More)
BACKGROUND To investigate possible causes for false-negative findings on PET scans for solid-type lung cancers, we retrospectively compared PET findings to clinical and pathological features using multivariate analysis. METHODS We reviewed PET/CT records, clinical records, preoperative thin-section CT images, and postoperative pathological records and(More)
PURPOSE Primary lung cancers have varying prognoses, even for tumors ≤3cm in diameter. Thus, a thorough evaluation is necessary for therapeutic planning. Two imaging biomarkers have been shown to be useful for predicting primary lung cancer prognosis: maximum standardized uptake values (SUVmax) on fluorodeoxyglucose positron emission tomography/computed(More)
We report an 8-year-old girl with seizures induced by micturition. Her seizures were characterized by extension of upper extremities with preserved consciousness. Magnetic resonance imaging and interictal electroencephalograms were normal. Ictal electroencephalogram showed low voltage fast waves without clear focal features followed by frontal dominant(More)
OBJECTIVES Positron emission tomography using [(18)F]-fluoro-2-deoxy-D-glucose ((18)F-FDG-PET) plays an important role in many oncological settings. In this study, we assessed the utility of (18)F-FDG PET-CT for predicting the histologic type and stage of thymic epithelial tumours. METHODS We retrospectively analyzed 58 patients with thymic epithelial(More)
BACKGROUND The purpose of this study was to assess the value of magnetic resonance imaging (MRI) and additional (18)F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) for tumor response to neoadjuvant chemotherapy (NAC) in patients with locally advanced rectal cancer (LARC). METHODS Data on 40 patients with LARC, who were(More)
RATIONALE AND OBJECTIVES To investigate how changes in luminance affect the detection accuracy of radiologists viewing chest radiograph images on high-resolution CRT monitors. MATERIALS AND METHODS Thirteen radiologists performed a detection task for 11 chest radiograph images with simulated nodules on a monitor with 11 luminance conditions (the maximum(More)
