“…En nuestro estudio, la frecuencia de cefalea secundaria fue del 8,2%, similar a los resultados informados en estudios previos. [6][7] Según las guías, no se recomienda realizar estudios de neuroimagenología de rutina en niños con cefalea y examen neurológico normal. Sin embargo, en la práctica clínica, los estudios de neuroimagenología suelen solicitarse durante la evaluación inicial de los niños con cefalea debido al temor a pasar por alto una enfermedad preexistente grave y a las mayores exigencias de los padres.…”

“…La tasa de neuroimagenología fue mayor en nuestro estudio que en los estudios previos publicados realizados en nuestro país. [7][8][9] El porcentaje más elevado podría deberse a las mayores exigencias de los padres y también de los médicos debido al aumento de demandas por negligencia médica, la saturación de las práctica en los consultorios externos y, por lo tanto, el tiempo limitado para realizar una anamnesis y examen físico minuciosos y también los incentivos financieros del seguro médico nacional financiado por el gobierno.…”

“…Según los informes, las tasas de anomalías detectadas en los estudios de neuroimagenología de los pacientes pediátricos con cefalea varían entre el 9,3% y el 21,6%. 6,7,9,10,13 Con el uso actual de las secuencias en los niños con cefalea, la tasa de anomalías detectadas aumentó al 52,8%, pero el beneficio clínico de estas secuencias sigue siendo limitado.…”

“…En estudios previos, la tasa de anomalías de la sustancia blanca variaron entre el 2,9% y el 4,4%. 7,8,10 Nuestro resultado fue más elevado que la tasa publicada anteriormente. Además, varios estudios en niños y adultos indican que los pacientes con migraña tienen un mayor riesgo de anomalías de la sustancia blanca en la RMN de cerebro que los pacientes sin migraña.…”

IMPORTANCE Incidental findings (IFs) are unexpected abnormalities discovered during imaging and can range from normal anatomic variants to findings requiring urgent medical intervention. In the case of brain magnetic resonance imaging (MRI), reliable data about the prevalence and significance of IFs in the general population are limited, making it difficult to anticipate, communicate, and manage these findings.OBJECTIVES To determine the overall prevalence of IFs in brain MRI in the nonclinical pediatric population as well as the rates of specific findings and findings for which clinical referral is recommended. DESIGN, SETTING, AND PARTICIPANTS This cohort study was based on the April 2019 release of baseline data from 11 810 children aged 9 to 10 years who were enrolled and completed baseline neuroimaging in the Adolescent Brain Cognitive Development (ABCD) study, the largest US population-based longitudinal observational study of brain development and child health, between September 1, 2016, and November 15, 2018. Participants were enrolled at 21 sites across the US designed to mirror the demographic characteristics of the US population.Baseline structural MRIs were centrally reviewed for IFs by board-certified neuroradiologists and findings were described and categorized (category 1, no abnormal findings; 2, no referral recommended; 3; consider referral; and 4, consider immediate referral). Children were enrolled through a broad school-based recruitment process in which all children of eligible age at selected schools were invited to participate. Exclusion criteria were severe sensory, intellectual, medical, or neurologic disorders that would preclude or interfere with study participation. During the enrollment process, demographic data were monitored to ensure that the study met targets for sex, socioeconomic, ethnic, and racial diversity. Data were analyzed from March 15, 2018, to November 20, 2020. MAIN OUTCOMES AND MEASURES Percentage of children with IFs in each category and prevalence of specific IFs.RESULTS A total of 11 679 children (52.1% boys, mean [SD] age, 9.9 [0.62] years) had interpretable baseline structural MRI results. Of these, 2464 participants (21.1%) had IFs, including 2013 children (17.2%) assigned to category 2, 431 (3.7%) assigned to category 3, and 20 (0.2%) assigned to category 4. Overall rates of IFs did not differ significantly between singleton and twin gestations or between monozygotic and dizygotic twins, but heritability analysis showed heritability for the presence or absence of IFs (h 2 = 0.260; 95% CI, 0.135-0.387). CONCLUSIONS AND RELEVANCEIncidental findings in brain MRI and findings with potential clinical significance are both common in the general pediatric population. By assessing IFs and concurrent developmental and health measures and following these findings over the longitudinal study course, the ABCD study has the potential to determine the significance of many common IFs.

Background MRI guidelines have been created to help clinicians order scans appropriately. Some scans in children are carried out under general anesthesia (GA) / sedation. Purpose To evaluate if the requirement for GA/sedation influences the way MRI brain scans are ordered. Study Type Retrospective. Population Children with MRI brain scans in 2015 to 2017. Field Strength 3T, 1.5T. Assessment Institutional Review Board approval for waiver of consent was obtained. Clinical MRI brain reports for children were classified into whether they conformed to the American College of Radiology (ACR) 2013 guidelines by research assistants under supervision of a pediatric radiologist. Scans were sorted into those with normal brains or abnormality. Statistical Test The statistical difference between groups was assessed using t‐test for continuous variables and chi‐square test for categorical variables with IBM SPSS 19. Results Of the total 1893 MRI scans, 431 were performed under GA and six under sedation. Of the 431 cases performed under GA/sedation, 383 (87.6%) were ordered according to guidelines. Of the 1456 cases that did not require GA/sedation, 710 (48.8%) conformed to guidelines. The percentage of scans ordered according to guidelines was 38.8% higher in those who had scans performed under GA/sedation (P < 0.001). MRI scans were normal in 635 (58.0%) out of the 1093 cases ordered according to guidelines and normal in 638 (79.8%) out of the 800 cases that did not follow guidelines. Scans not ordered according to guidelines had higher proportion of normal scans (21.8%) compared with those ordered according to guidelines (P < 0.001). Data Conclusion Higher adherence to imaging guidelines is seen in younger patients who were exposed to the risks of GA/sedation for the MRI. Scans not adhering to guidelines had a higher percentage of having no brain abnormality detected. Level of Evidence: 3 Technical Efficacy: Stage 6 J. Magn. Reson. Imaging 2019;49:e250–e255.
