Dose reduction in CT while maintaining diagnostic confidence: diagnostic reference levels at routine head, chest, and abdominal CT--IAEA-coordinated research project.

Comparison of CT results with diagnostic reference levels revealed the need for revisions, partly because the newer scanners have improved technology that facilitates lower patient doses.

Radiation dose in abdominal computed tomography: the role of patient size and the selection of tube current.

To produce CT scans of similar quality, a simple prediction equation can be developed for any scanner to optimize radiation dose for patients of all body weights.

Radiation doses to patients receiving computed tomography examinations in British Columbia.

There was considerable variation in the DLP and patient radiation dose for a specific exam among hospitals, and reference doses and patient doses were higher than those found in similar recent surveys carried out in the United Kingdom and the European Union.

Cancer screening with CT: dose controversy

The basis for radiation risk estimation is discussed, a non-negligible radiation risk has to be postulated even at very low doses, but estimates depend heavily on the chosen mathematical model.

Radiation exposure of patients undergoing whole-body dual-modality 18F-FDG PET/CT examinations.

The dosimetric concepts presented in this study provide a valuable tool for the optimization of whole-body 18F-FDG PET/CT protocols and further reduction of patient exposure can be achieved by modifications to the existing hardware and software of PET/ CT systems.

A positron emission tomography/computed tomography (PET/CT) acquisition protocol for CT radiation dose optimization

The current PET/CT imaging acquisition protocol was improved by decreasing the radiation risks without sacrificing the diagnostic values by using a lower radiation dose, which did not significantly affect attenuation correction and anatomic delineation in PET.

Estimated radiation risks potentially associated with full-body CT screening.

PURPOSE To estimate the radiation-related cancer mortality risks associated with single or repeated full-body computed tomographic (CT) examinations by using standard radiation risk estimation…

Diagnostic CT scans: assessment of patient, physician, and radiologist awareness of radiation dose and possible risks.

Patients are not given information about the risks, benefits, and radiation dose for a CT scan, and patients, ED physicians, and radiologists alike are unable to provide accurate estimates of CT doses regardless of their experience level.

Strategies for CT radiation dose optimization.

Basic principles of CT radiation exposure are outlined and the need for CT radiation dose optimization based on modification of scanning parameters and application of recent technologic innovations is emphasized.

Dual-modality PET/CT scanning with negative oral contrast agent to avoid artifacts: introduction and evaluation.

Mannitol-LBG may be used as a negative oral contrast agent at PET/CT scanning because it provides excellent bowel distention while avoiding contrast material-induced PET artifacts.
