background: despite developments in surgical treatment, radiation therapy, and chemotherapy protocols, tumor recurrence and metastasis are still major problems in breast cancer management. the aim of the present report was to review and compare the performance of pet/ct with some of the conventional imaging modalities in detection of breast cancer recurrence. methods: a literature search was pe...

introduction:myocardial 18f-fdg uptake is highly variable in oncologic whole body 18f-fdg pet/ct studies, ranging from quite intense to minimal distribution. intense or heterogeneous myocardial 18f-fdg uptake is undesirable as it may interfere with the visual or quantitative evaluation of tumoral invasion and metastases in pericardium, myocardium or adjacent mediastinal structures. the diet, as...

introduction: an efficient method of tomographic imaging in nuclear medicine is positron emission tomography (pet). compared to spect, pet has the advantages of higher levels of sensitivity, spatial resolution and more accurate quantification. however, high noise levels in the image limit its diagnostic utility. noise removal in nuclear medicine is traditionally based on fourier decomposition o...

conclusions 18 f fdg pet/ct is a valuable imaging tool in initial and subsequent treatment strategy in patients with breast cancer by providing additional nodal and distant metastasis and may have the promising future potential to be as the imaging modality of choice for accurate assessment of disease extension in breast cancer in routine clinical practice. methods of a total 256 patients with ...

a 65 year old male with metastatic colorectal cancer (mcrc) in the liver was referred for selective internal radionuclide therapy (sirt) following a history of extensive systemic chemotherapy. 90y pet imaging was performed immediately after treatment and used to confirm lesion targeting and measure individual lesion absorbed doses. lesion dosimetry was highly predictive of eventual response in ...

Objective(s): In view of somatostatin receptor (SSR) expression on cell membranes of the majority of neuroendocrine tumors (NETs), functional imaging exploiting analogs of SSR alongside the anatomical imaging is the mainstay of this diagnostic modality. In this prospective study, we assessed and directly compared the diagnostic parameters of 68Ga-DOTATATE PET/CT and 99...

pet (positron emission tomography) is a powerful imaging technique that can provide quantitative information on the distribution of positron emitter labeled radiopharmaceuticals (pet radiopharmaceuticals) in the body. positrons (ß+) are positively charged beta particles. they are emitted when the atom is proton rich. a positron has only a transient existence. after losing all of its kinetic ene...

Neurolymphomatosis is a rare manifestation of non-Hodgkin lymphoma characterized by infiltration of peripheral nerves, nerve roots, plexus and cranial nerves by malignant lymphocytes. This report presents positron emission tomography/computed tomography (PET/CT)imaging with 2-deoxy-2-18F-fluoro-D-glucose (18F-FDG) in 3 cases of non-Hodgkin lymphoma with nerve infiltration, including one newly d...

Objective(s): We performed a phase IIa clinical trial of trans-1-amino-3-18Ffluoro-cyclobutane carboxylic acid (anti-18F-FACBC), a synthetic amino acid analog for PET, in patients with metastatic prostate cancer. Methods: The study subjects consisted of 10 untreated prostate cancer patients having lymph node and/or bone metastasis. Five patients underwent whole-body PET 5 and 30 min after intra...
