OBJECTIVE This study aimed to evaluate the efficiency of 18F-FDG PET/CT in suspected recurrence of epithelial ovarian cancer, after treatment, comparing outcomes of PET/CT with histological tumor subtype, CA-125 serum levels, and findings of conventional diagnostic imaging modalities (CI). METHODS Data from 121 women who underwent FDG PET/CT for suspected(More)
PET Imaging with [11C]-choline has become a useful tool in the investigation of prostate cancer, with as main application the assessment of previously treated patients presenting with rising PSA and negative conventional imaging procedures. In this case report we describe [11C]-choline PET/CT findings in a patient with a locally advanced cancer, which could(More)
The technological advances in imaging and production of radiopharmaceuticals are driving an innovative way of evaluating the targets for antineoplastic therapies. Besides the use of imaging to better delineate the volume of external beam radiation therapy in oncology, modern imaging techniques are able to identify targets for highly specific medical(More)
Imaging with positron emission tomography (PET)/computed tomography (CT) is crucial in the management of cancer because of its value in tumor staging, response assessment, restaging, prognosis and treatment responsiveness prediction. In the last years, interest has grown in texture analysis which provides an "in-vivo" lesion characterization, and predictive(More)
Standardization of FDG PET-CT is becoming a reality, at least in centers that perform clinical trials. Non-FDG radiopharmaceuticals used with PET/CT are far from standard in clinical trials and in clinical use. This article only gives an example of different protocols and indications related to the availability of different radiopharmaceuticals. This(More)
The aim of this study was to evaluate the usefulness of fine-needle aspiration cytology (FNAC) and (99m)Tc-pertechnetate scintigraphy (TS) together in patients with differentiated thyroid carcinoma. Data from a series of 357 patients (284 women and 73 men, median age 43 years, range 19-73) with solitary thyroid nodule and no signs of hyperfunction, who had(More)
Prostate cancer bone metastases occur frequently in advanced cancer and this is matter of particular attention, due to the great impact on patient's management and considering that a lot of new emerging therapeutic options have been recently introduced. Imaging bone metastases is essential to localize lesions, to establish their size and number, to study(More)
