The number of computed tomographic (CT) studies performed is increasing rapidly. Because CT scans involve much higher doses of radiation than plain films, we are seeing a marked increase in radiation exposure in the general population. Epidemiologic studies indicate that the radiation dose from even two or three CT scans results in a detectable increase in the risk of cancer, especially in children. This article summarizes the facts about this form of radiation exposure and the implications for… Expand
The Use of Low-Dose CT Scanning
TLDR
With improved CT protocols using the information obtained during a CT scan, less radiation is required to provide adequate information on urinary stone disease. Expand
Radiation exposure in cardiac multislice spiral computed tomography (MSCT)
TLDR
The technical factors that affect the radiation dose in cardiac CT diagnostic procedures are reviewed, the parameters that are used to measure and compare radiation doses, the magnitude of radiation exposure, and how to efficiently reduce it are reviewed. Expand
Computed Tomography Radiation Dosimetry: From the Indicators to the Indications
TLDR
In the present review, all available dose metrics used in CT dosimetry are described, evaluated, and compared. Expand
Variability of radiation exposure with in‐office sinus computed tomography examinations
TLDR
An increasing number of patients seeking care by an otolaryngologist are undergoing computed tomography (CT) examinations via in‐office CT scanners, and a recent study of common CT examinations demonstrated significant variability in radiation dosages for similar studies. Expand
Fundamentals of X-Ray Computed Tomography: Acquisition and Reconstruction
TLDR
Clinically, CT is widely used in the acute setting but also for chronic conditions and the potential for contrast-induced acute kidney injury are the two major challenges for CT. Expand
Computed tomography dose optimization.
TLDR
Use of computed tomography as a medical diagnostic imaging tool has increased in recent decades because of its technical advances in data acquisition speed and image reconstruction technology, but concerns among radiologic professionals and the public regarding CT dose resulted in increasing attention to dose reduction. Expand
PEDIATRIC DOSE REDUCTION IN COMPUTED TOMOGRAPHY
TLDR
New considerations with respect to study quality, those factors which influence CT use, and strategies for dose reduction (that is, optimization) will also be reviewed. Expand
The implementation of (ultra-low dose) CT protocols in PET/CT
TLDR
To accurately assess radiation risks and keep radiation doses as low as reasonably achievable, radiology departments must be knowledgeable about the doses delivered during various types of CT studies performed on patients. Expand
Understanding Computed Tomography (CT) Dose Reduction Techniques and Principles in a Simplified Way
TLDR
A review of CT dose reduction techniques will give readers an insight to strategies for dose reduction and principles behind them. Expand
Minimizing Patient Exposure to Ionizing Radiation from Computed Tomography Scans
TLDR
The number of CT scans ordered in adults and children has increased by about 7 times over the last 10 years and this trend of increased use has also been seen at Baylor University Medical Center when a second CT scanner was added to the ED during the recent remodel of the department. Expand

CT scanning: patterns of use and dose.
TLDR
In most large hospitals in the United States CT scanning probably accounts for more than 10% of diagnostic radiology examinations and about two-thirds of the radiation dose, and most patients have multiple scan sequences. Expand

TLDR
The progress that has been made in changing practices of the radiology community and attention given to dose reduction by CT manufacturers are reviewed and the importance of decreasing unnecessary CT examinations in children is emphasized. Expand

TLDR
If optimal performance is to be achieved, it is necessary to understand how these factors influence image formation and affect radiation dose, and apply methodology for image quality and dose analysis at each stage in the development and use of X-ray equipment. Expand
Diagnostic CT scans: assessment of patient, physician, and radiologist awareness of radiation dose and possible risks.
TLDR
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. Expand
Invited article: Helical/spiral CT scanning: a pediatric radiology perspective
TLDR
The technical and clinical considerations relevant to scanning the pediatric patient are reviewed and suggestions for protocol development are offered. Expand
Estimated risks of radiation-induced fatal cancer from pediatric CT.
TLDR
It is suggested that pediatric CT will result in significantly increased lifetime radiation risk over adult CT, both because of the increased dose per milliampere-second, and the increased lifetime risk per unit dose. Expand
CT dose reduction and dose management tools: overview of available options.
TLDR
Modulation of the x-ray tube current during scanning is one effective method of managing the dose, but the tube current must be appropriately adapted to patient size for diagnostic image quality to be achieved. Expand
Mass screening with CT colonography: should the radiation exposure be of concern?
TLDR
The benefit-risk ratio potentially is large for CTC, and the cancer risks associated with the radiation exposure are unlikely to be zero, but they are small. Expand

TLDR
The effective dose from CT can be estimated by using Monte Carlo methods to simulate CT of a mathematical patient model, by estimating the energy imparted to the body region being scanned, or by using conversion factors for general anatomic regions. Expand
