UNLABELLED The purpose of the study was to evaluate the performance of dual-head coincidence gamma camera imaging using FDG in association with serum marker assays in identifying lung carcinoma in patients with abnormal findings on chest radiography. METHODS A prospective evaluation of FDG imaging with coincidence detection emission tomography (CDET) using a dual-head gamma camera combined wi...

UNLABELLED The purpose of the study was to evaluate the 6-[18F]fluoro-L-dopa (FDOPA) kinetics with PET in patients with treated melanoma metastases and to compare it with the standard tracer 18F-FDG as well as with the perfusion tracer (15)O-water in selected cases. METHODS The study included 11 patients (22 lesions) with pretreated metastatic melanomas. Dynamic studies with FDG and in select...

BACKGROUND Positron emission tomography (PET) with F-18-labeled fluorodeoxyglucose (FDG) provides remarkable accuracy in detection, treatment monitoring and follow-up of systemic malignant lymphoma. Its value in the management of patients with primary central nervous system lymphoma (PCNSL) is less clear. PATIENTS AND METHODS In a prospective trial, 42 FDG-PET examinations were performed in t...

OBJECTIVE The clinical usefulness of FDG-PET in the follow up of post-operative patients with endometrial cancer was retrospectively evaluated. METHODS Twenty-one post-operative patients with endometrial cancer received 30 FDG-PET examinations to evaluate recurrence or response to treatment. The findings of FDG-PET were compared with their serum levels of tumor markers, CT and/or MRI findings...

background: in the era of well-developed site-specific treatment strategies in cancer, identification of occult primary is of paramount importance in cup patients. furthermore, exact determination of the extent of the disease may help in optimizing treatment planning. the aim of the present study was to investigate additional value of f-18 fdg pet/ct in patients with cancer of unknown primary (...

Despite recent advances in medical and surgical treatments to prevent arterial stroke, the cerebrovascular burden of atherosclerosis remains high. Factors associated with a high risk for arterial stroke include stenosis .50% and ulcerated plaque. Given the important role of inflammation in atherosclerotic plaque progression and rupture, a measure of plaque inflammation may help stratify arteria...

Background: F-FDG PET/CT imaging is widely utilized in the clinical evaluation of patients with suspected or documented lymphoma. The aim was to describe our cumulative experience with a multimodal F-FDG-directed lymph node surgical excisional biopsy approach in patients with suspected lymphoma. Methods: Thirteen patients (mean age 51 (±16;22–76) years), with suspected new or suspected recurren...

UNLABELLED The feasibility of (18)F-3'-fluoro-3'-deoxy-L-thymidine PET (FLT PET) for detecting laryngeal cancer was investigated and compared with (18)F-FDG PET. METHODS Eleven patients diagnosed with or strongly suspected of having recurrent laryngeal cancer and 10 patients with histologically proven primary laryngeal cancer underwent attenuation-corrected (18)F-FLT PET imaging 60 min after ...

solitary pulmonary nodule (spn) is a frequent finding on the chest x-ray and computed tomography. nuclear medicine techniques play an important role in the diagnosis and management of spn. in the current review, we briefly will explain the different nuclear medicine modalities in this regard including positron emission tomography (pet) using 18-f-fdg, and 11-c-methionine, and single photon emis...
