UNLABELLED The purpose of this study was to evaluate the added value of a fourth and subsequent follow-up PET/CT scans to clinical assessment and impact on patient management in patients with colorectal cancer. METHODS This was an institutional review board-approved, retrospective study. Eight hundred twenty-two patients with biopsy-proven colorectal cancer, who underwent (18)F-FDG PET/CT, we...

INTRODUCTION The use of 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET) scanning for baseline staging and assessment of treatment response for higher grade lymphomas is considered to be the standard of care. Evaluation of lymphomatous bone marrow infiltration on 18F-FDG PET can usually distinguish between normal regenerating marrow following chemotherapy by a characteristic pa...

The standard protocols described in this document cover subject preparation, injection activity, accumulation time, subject positioning, scan time and the criteria for determination of reconstruction parameters for each PET camera based on phantom data. The idea is to standardize the methods and conditions that would affect the PET image qualitatively or quantitatively. However, the image quali...

BACKGROUND PET scan is a non-invasive, complex and expensive medical imaging technology that is normally used for the diagnosis and treatment of various diseases including lung cancer. OBJECTIVES The purpose of this study is to assess the cost effectiveness of this technology in the diagnosis and treatment of non- small cell lung carcinoma (NSCLC) in Iran. MATERIALS AND METHODS The main ele...

Background: Patients with advanced head and neck cancer at initial presentation are at high risk for recurrent disease. The outcome of salvage treatment for recurrent disease is significantly better for recurrences diagnosed at an early stage. Data regarding the use of PET for post-treatment surveillance in patients without a high clinical suspicion for recurrence are limited. Objective: To eva...

The use of positron emission tomography (PET) is increasing rapidly in the United States, with the most common use of PET scanning related to oncology. It is especially useful in the staging and management of lymphoma, lung cancer, and colorectal cancer, according to a panel of expert radiologists, surgeons, radiation oncologists, nuclear medicine physicians, medical oncologists, and general in...

In Hodgkin's lymphoma (HL), PET imaging should be performed in all patients, particularly in stage I or II disease where change in staging will alter management. For aggressive Non-Hodgkin's lymphoma (NHL), PET imaging is valuable to provide a baseline for response evaluation. For indolent NHL, it is concluded that PET imaging is not generally indicated. For HL, a negative FDG-PET scan is highl...
