Pediatric Positron Emission Tomography–Computed Tomography Protocol Considerations
Seminars in Ultrasound, CT and MRI, 2008Pediatric body oncology positron emission tomography-computed tomography studies require special considerations for optimal diagnostic performance while limiting radiation exposure to young patients. Differences from routine adult procedures include the patient preparation phase, radiopharmaceutical dose, computed tomography acquisition parameters, and

Positron Emission Tomography-Computed Tomography in Liver Imaging
Seminars in Ultrasound, CT and MRI, 2013The relatively new technique of positron emission tomography (PET) that incorporates both anatomy and function is increasingly being utilized in oncological imaging. This review assesses the use of PET of the liver for optimal and appropriate patient clinical management.

Positron Emission Tomography–Computed Tomography Patient Management and Workflow
Seminars in Ultrasound, CT and MRI, 2008This article reviews the major considerations involved in optimizing positron emission tomography-computed tomographic (PET-CT) workflows including patient management and specific acquisition, processing, and archiving procedures. Due to the dual modality nature of PET-CT and the needs of the patients typically undergoing these examinations, there is a

Role of Positron Emission Tomography/Computed Tomography in Dementia
Radiologic Clinics of North America, 2013This article provides a clinically based review of positron emission tomography (PET) imaging for dementia. Significant advances in nuclear medicine and molecular imaging techniques have improved the understanding of the genetic and molecular processes that define neurodegenerative dementia diseases. Metabolic imaging remains constant in its ability to

Cervical Cancer: Positron Emission Tomography and Positron Emission Tomography/Computed Tomography
2009Worldwide, cervical cancer is the second most common cause of cancer-related deaths in women. Imaging has not traditionally played a large role in the diagnosis and staging of cervical cancer. Staging of cervical cancer, due to the high incidence in developing countries, is largely based on clinical examination per the Internationale de Gynecologie et ...

Role of Positron Emission Tomography/Computed Tomography
2016Colorectal cancer (CRC) incidence and mortality rates are extremely variable around the world. CRC is the second most commonly diagnosed cancer in both genders [1]. Many patients are cured with initial surgery for primary disease and postoperative chemotherapy.

Positron Emission Tomography/Computed Tomography Potential Pitfalls and Artifacts
Current Problems in Diagnostic Radiology, 2009With the recent use of 18-fluoro-2-deoxyglucose (FDG) positron emission tomography (PET) for tumor staging and treatment response, it is important to recognize many pitfalls, artifacts, and benign uptakes that are commonly encountered. Normal physiology can explain many regions of increased FDG activity, as well as incidental benign tumors and benign ...

Positron Emission Tomography/Computed Tomography: Protocol Issues and Options
Seminars in Nuclear Medicine, 2006Combined positron emission tomography/computed tomography (PET/CT) became FDA-approved for clinical use in late 2001. There are several design advantages of combined PET/CT over PET and CT acquired on separate devices, including more accurate CT and PET data co-registration, improved lesion localization, consolidation of imaging studies, and reduced ...

Therapy Response Evaluation with Positron Emission Tomography-Computed Tomography
Seminars in Ultrasound, CT and MRI, 2010Positron emission tomography-computed tomography with F-18-fluorodeoxyglucose is widely used for evaluation of therapy response in patients with solid tumors but has not been as readily adopted in clinical trials because of the variability of acquisition and processing protocols and the absence of universal response criteria.
