“…9-15 Investigators have emphasized that the radiation risk from a single imaging modality can be high. 3,7,8,10,13,15 However, children with complex heart diseases are often exposed to repetitive imaging. 16 According to current guidelines from the International Committee on Radiation Protection (ICRP), stochastic exposure risks (i.e.…”

Background Children with heart disease are frequently exposed to imaging examinations using ionizing radiation. Although radiation exposure is potentially carcinogenic, there are limited data on cumulative exposure and the associated cancer risk. We evaluated the cumulative effective dose (ED) of radiation from all radiation examinations to estimate the lifetime attributable risk (LAR) of cancer in children with heart disease. Methods and Results Children ≤6 years of age who had previously undergone 1 of 7 primary surgical procedures for heart disease at a single institution between 2005 and 2010 were eligible. Exposure to radiation-producing examinations was tabulated, and cumulative ED was calculated in millisievert (mSv). These data were used to estimate LAR of cancer above baseline using the approach of the Committee on Biological Effects of Ionizing Radiation VII. The cohort included 337 children exposed to 13,932 radiation examinations. Conventional radiographs represented 92% of examinations, while cardiac catheterization and computed tomography accounted for 81% of cumulative exposure. Overall median cumulative ED was 2.7 mSv (range 0.1–76.9 mSv), and the associated LAR of cancer was 0.07% (range 0.001–6.5%). Median LAR of cancer ranged widely depending on surgical complexity (0.006–1.6% for the 7 surgical cohorts) and was twice as high in females per unit exposure (0.04% versus 0.02% per 1 mSv ED for females versus males, respectively; p<0.001). Conclusions Overall radiation exposures in children with heart disease are relatively low, however select cohorts receive significant exposure. Cancer risk estimation highlights the need for limiting radiation dose, particularly for high-exposure modalities.

“…It exposes patients to ionizing radiation, and ill children with suspected pneumonia may receive multiple CXRs, posing a small increased risk of cancer later in life. [2][3][4] Lung ultrasonography (LUS) has several potential advantages over CXR. Compared with CXR, LUS does not expose the child to ionizing radiation, when used to address specific diagnostic questions requires minimal training for the provider, and can be performed at the point of care.…”

“…[33][34][35] Magnetic resonance imaging (MRI) of the lungs has slowly evolved technically over the past 30 years to improve imaging of the pulmonary parenchyma and has progressed tremendously in the past decade. Although several strategies are available to optimize dose reduction, clinicians should always weigh the potential future risks against the short-term benefits when evaluating patients with bronchiectasis.…”

Bronchiectasis is the pathologic definition of irreversibly dilated bronchi and reflects the final common pathway of a variety of underlying diseases and unrelated pulmonary insults. It is a relatively uncommon but devastating disease associated with high morbidity and mortality. Several entities, congenital or acquired, predispose to bronchiectasis. Demographic data, associated symptoms, laboratory results, and imaging findings allow early diagnosis of bronchiectasis and direct the suspicion to certain etiologies. It is important for clinicians and radiologists to be familiar with the clinical and imaging features of bronchiectasis so that these patients receive an early diagnosis and appropriate follow-up, which ultimately will lead to improved prognosis and quality of life.
