“…A technical disadvantage of conventional color Doppler ultrasound is the inability to analyze the microvascular circulation. The recently developed three‐dimensional (3D) Doppler tools MV‐Flow and LumiFlow have overcome this limitation and have been provided to study the low‐velocity flow, with seminal applications in the study of the fetal head microvasculature by Giuffrida et al 1 and the study of the posterior fossa by Dall'Asta et al 2 …”

“…In addition, MRI can assess cerebellar lesions, which may also be associated with a higher risk of neurological abnormalities (11) . Despite those advantages, there is as yet no consensus regarding which neuroimaging examination should be performed, when it should be performed, and what its prognostic value is (11)(12)(13)(14)(15) .…”

Alterations on magnetic resonance imaging of the neonatal brain: correlations with prenatal risk factors and transfontanellar ultrasound findings

Objective: To describe the alterations seen on magnetic resonance imaging (MRI) of the brain in newborns, correlating those alterations with the transfontanellar ultrasound (TFUS) findings, and to describe the main risk factors identified. Materials and Methods: We evaluated the examinations of 51 patients who were submitted to brain MRI with a neonatal protocol during hospitalization. We evaluated the MRI findings and correlated them with previous TFUS findings, using the last TFUS performed in order to minimize the risk of bias. Data were obtained from medical records, and the images were reviewed by a radiologist specializing in neuroimaging. Results: Of the 51 patients evaluated, 21 (41.2%) were extremely preterm infants and 22 (43.1%) were extremely-low-birth-weight infants. Alterations were seen on 16 (31.4%) of the TFUS examinations and on 30 (58.8%) of the brain MRI scans, the most common finding being germinal matrix hemorrhage. The positive and negative predictive values of TFUS in relation to MRI were 87% and 54%, respectively. Conclusion: Because TFUS proved to be capable of distinguishing mild and moderate (grade I and II) germinal matrix hemorrhage from the severe forms (grades III and IV), it can be considered a good tool for screening and follow-up, especially in infants with severe disease and risk factors.

“…Além disso, pela RM é possível avaliar lesões cerebelares, que também podem estar associadas a um maior risco de anormalidades neurológicas (11) . Apesar de a RM apresentar algumas vantagens sobre a USTF, ainda existem controvérsias sobre qual exame de neuroimagem deve ser realizado, quando executá-lo e o seu valor no prognóstico (11)(12)(13)(14)(15) .…”

Resumo Objetivo: Avaliar alterações encontradas nas ressonâncias magnéticas (RMs) encefálicas neonatais, correlacionando com a ultrassonografia transfontanelar (USTF), e descrever os principais fatores de risco encontrados. Materiais e Métodos: Foram avaliados exames de 51 pacientes que realizaram RM utilizando protocolo neonatal durante internação hospitalar, correlacionando com resultados da USTF prévia, sendo utilizada, para minimizar as chances de viés, a última USTF realizada. Os dados foram obtidos de prontuário médico e as imagens foram revisadas por médico radiologista especialista em neuroimagem. Resultados: A população foi composta majoritariamente de recém-nascidos prematuros extremos (21; 41,2%) e de extremo baixo peso (22; 43,1%). Foram encontradas alterações em 16 (31,4%) das USTFs e em 30 (58,8%) das RMs, sendo a hemorragia da matriz germinativa o achado mais frequente. Os valores preditivos positivo e negativo da USTF em relação à RM foram de 87% e 54%, respectivamente. Conclusão: A USTF mostrou-se importante na distinção entre os graus de hemorragia da matriz germinativa leve e moderada (I e II) dos graus acentuados (III e IV), sendo considerada um bom exame de rastreio e acompanhamento, principalmente em pacientes mais graves e com fatores de risco.
