PET and PET/CT imaging for the earliest detection and treatment of colorectal carcinoma

Abstract

ABSTRACT

Common causes of false positive F18 FDG PET/CT scans in oncology

“…Utilization of PET/CT has been shown to be beneficial in altering the management of patients compared to imaging with just CT or PET alone (Mavi et al, 2005). PET/CT is currently utilized in the diagnosis and staging of multiple malignancies (Carter and Kotlyarov, 2005). It is approved in the United States for the characterization of solitary pulmonary nodules, the diagnosis-stagingrestaging of colon carcinoma, lymphoma, melanoma, esophageal carcinoma, and head and neck cancers.…”

Biodistribution of the radiopharmaceutical sodium pertechnetate after biliopancreatic bypass with a duodenal switch

“…Radiographs and scintigraphies may show an air fluid level in the gastric pouch, malposition, angulation of the band bands, problems with gastric emptying, and gastric obstruction (O'Brien et al, 2005). The radiopharmaceuticals are frequently used in diagnostic procedures (Bingener-Casey et al, 2002, Carter & Kotlyarov, 2005. Examinations of gastric emptying, patency of anastomoses, enterogastric reflux, hepatic and thyroid diseases, osteoporosis and metastasis, frequently are carried after bariatric surgery (Kitabaiashi et al, 2002;Fonseca et al, 2000;Badiali et al, 2001;Obradovic et al, 2000).…”

FDOPA-(18F): a PET radiopharmaceutical recently registered for diagnostic use in countries of the European Union

“…For historical reasons, PET studies initially focused on the brain and the heart. Now, PET is often used in oncologic indications (Carter and Kotlyarov, 2005). This development resulted from the use of fluorodeoxyglucose-(18F) or FDG, and from the successful application of FDG-(18F) PET to a growing number of important human cancers to solve clinical problems at varying stages of diagnosis, staging and follow-up.…”
