“…Hence, the use of DLP to estimate E appears to be a reasonably robust method for estimating effective dose. Similarly, Huda has compared effective dose, as calculated from the NRPB data 39 , to estimates of energy imparted in order to develop conversion coefficients by which to later estimate effective dose from energy imparted 42 .…”

Radiation exposure in patients with subarachnoid hemorrhage: a quality improvement target

Object The care of patients with subarachnoid hemorrhage (SAH) has improved dramatically over the last decades. These gains are the result of improved microsurgical, endovascular, and medical management techniques. This intensive management subjects patients to multiple radiographic studies and thus increased radiation exposure. As greater understanding of the risks of radiation exposure develops, physicians must be better equipped to balance the need for optimal SAH management with the minimization of patient exposure to radiation from imaging studies. The goal in the current study was to determine if there is an opportunity for a reduction in radiation dose without a change in the quality of treatment in patients with SAH. Methods A retrospective chart review of all patients hospitalized for SAH at the Brigham and Women's Hospital in the period from January 1, 2009, to August 31, 2010, was performed. The authors calculated cumulative and imaging study–specific radiation doses, determined the time of day that imaging studies were performed, and surveyed neurosurgeons regarding issues surrounding imaging-related radiation exposure. Results The data for 77 patients were analyzed. The mean cumulative radiation dose during hospitalization was 2.76 Gy per patient (range 0.46–8.32 Gy). The mean radiation exposure from each CT, CT angiography (CTA), and angiography study was 0.08, 0.29, and 0.77 Gy (ranges 0.02–0.40, 0.15–0.99, and 0.11–4.36 Gy, respectively). Subgroup analysis of the top quartile of patients in terms of total radiation dose revealed a mean cumulative radiation dose of 4.78 Gy (range 3.42–8.32 Gy), mean cumulative number of CT and CTA scans of 14, and mean CT or CTA scan per day of 0.5 (maximum 0.8). Seventeen percent of the noncontrast head CT studies were performed just prior to morning rounds, more than double the 8% expected rate at random. Thirty-four percent of the repeat noncontrast head CTs did not show any change between scans, as documented on radiology reports. When surveyed, a majority of neurosurgeons incorrectly estimated the radiation dose typically received from CT, CTA, and angiography studies, and 65% asserted that radiation exposure is “not important” or only “somewhat important” when considering whether to order an imaging study. Conclusions Study findings suggested that patients with SAH have significant imaging-related exposure to radiation. The authors believe it is possible to continue the current improved outcomes in SAH with a significant reduction in radiation exposure from imaging studies. This analysis highlights the significance of accurate assessment of radiation exposure as a quality improvement target.

“…3,4 Multiple factors including increased sensitivity of growing tissues to ionizing radiation, small cross-sectional area in children, and long latent period of oncogenic effects of ionizing radiation contribute to a more pronounced effect of ionizing radiation in children than in adults. 5,6 Steps to minimize the risk for potential long-term complications of ionizing radiation are therefore particularly relevant in children undergoing multiple follow-up CT scans. An arbitrary reduction in ionizing radiation may result in significant deterioration of image quality and may render CT studies clinically unacceptable.…”

An approach for the estimation of effective radiation dose at CT in pediatric patients.

Abstract: The values for energy imparted at CT in pediatric patients were generally lower than in adults. The smaller mass of children, however, caused the corresponding effective doses to be higher than those in adults undergoing similar CT examinations.
