Objectives To have a global picture of the recurrent use of CT imaging to a level where cumulative effective dose (CED) to individual patients may be exceeding 100 mSv at which organ doses typically are in a range at which radiation effects are of concern Methods The IAEA convened a meeting in 2019 with participants from 26 countries, representatives of various organizations, and experts in radiology, medical physics, radiation biology, and epidemiology. Participants were asked to collect data… 

Cumulative effective dose from recurrent CT examinations in Europe: proposal for clinical guidance based on an ESR EuroSafe Imaging survey

A survey carried out in Europe aims to estimate the proportion of patients that undergo CT examinations and are exposed to a CED of more than 100 mSv and suggests some practical actions to support the management of cumulative effective dose and to refine or improve practice where recurrent examinations are required.

Challenges for managing the cumulative effective dose for patients.

The challenges to manage the existing situation are summarised and the main aspects identified are: new technology with dose reduction techniques, education on the proper use of cumulative effective dose for referrers and practitioners including information for patients, and patient dose management systems with alerts on the cumulative high doses.

How much should we be concerned about cumulative effective doses in medical imaging?

Recommendations on further strengthening of optimisation should be applied to imaging procedures for all patients with special focus on those performed on children and adolescents, followed by action to strengthen the radiation protection of patients undergoing recurrent imaging.

Patients undergoing recurrent CT scans: assessing the magnitude

The authors are in an unprecedented era, where patients undergoing multiple CT exams and receiving CED ≥ 100 mSv are not uncommon and a sizable fraction among them are below 50 years of age, which leads to cumulative radiation dose to individual patients at which radiation effects are of real concern.

Recurrent imaging procedures with ionising radiation on the same patient. Should we pay more attention?

Cumulative doses to individual patients from recurrent CT the ‘ total radiation ’ from other high dose imaging modalities such as interventional and PET-CT ( PET emission the) are reported, valuable for epidemiological studies on radiation effects on the group of patients.

Patients undergoing multiphase CT scans and receiving a cumulative effective dose of ≥ 100 mSv in a single episode of care

The finding of a sizeable percentage of patients undergoing CT exams and receiving CED ≥ 100 mSv in a single episode of care points toward the need of imaging appropriateness criteria, to revise the routine protocols, to replace older machines, and to provide to the radiologist the patient’s prior radiation history to facilitate an appropriate decision-making process.

The cumulative radiation dose paradigm in pediatric imaging.

It is worthwhile to review the general construct of CED, including the comparison between the relative percentage occurrence in adult and pediatric populations, the relevant pediatric medical settings in which high CED occurs, the advances in medical care that may affect CED determinations in the future, and offer proposals for the application of the CED paradigm, considering the unique aspects of pediatric care.

Patients undergoing recurrent CT exams: assessment of patients with non-malignant diseases, reasons for imaging and imaging appropriateness

To determine percent of patients without malignancy and ≤ 40 years of age with high cumulative radiation doses through recurrent CT exams and assess imaging appropriateness, a cohort of patients who received cumulative effective dose over a 5-year period was identified.

Multicentric study of patients receiving 50 or 100 mSv in a single day through CT imaging—frequency determination and imaging protocols involved

In the first study of its kind, it is reported that patients with 50 mSv+ in a single day or a single exam are not rare and the information on imaging protocols leading to such doses and their frequency has been provided to help develop dose management strategies.

The annual CED was significantly higher in incident patients and in patients with ischaemic heart disease and cancer, and in many patients associated with high cumulative estimated doses of ionizing radiation.

Recurrent CT, cumulative radiation exposure, and associated radiation-induced cancer risks from CT of adults.

While most patients accrue low radiation-induced cancer risks, a subgroup is potentially at higher risk due to recurrent CT imaging, and Cumulative CT radiation exposure added incrementally to baseline cancer risk in the cohort.

It is shown that a significant fraction of surviving hemodialysis patients during a 3-year period receives estimated radiation doses that may put them at an increased risk for cancer.

EVAR patients received high radiation doses and the excess cancer risk attributable to radiation exposure is not negligible, and the unenhanced scan and the venous phase of the MDCT angiography could have been omitted without compromising the utility of the examination and with a significant reduction of doses and associated risks.
