“…24 Moreover, preterm infants are vulnerable to respiratory and hemodynamic instability and movement artifacts. 7,9 Therefore, acquisition and processing of DTI data must be handled with dedicated care, which is essential to avoid misinterpretation. This is appropriately described in technical DTI reports, [5][6][7]25,26 but, paradoxically, such work receives little attention in clinical research.…”

BACKGROUND AND PURPOSE:Neonatal DTI enables quantitative assessment of microstructural brain properties. Although its use is increasing, it is not widely known that vast differences in tractography results can occur, depending on the diffusion tensor estimation methodology used. Current clinical work appears to be insufficiently focused on data quality and processing of neonatal DTI. To raise awareness about this important processing step, we investigated tractography reconstructions of the fornix with the use of several estimation techniques. We hypothesized that the method of tensor estimation significantly affects DTI tractography results.

“…MRI provides excellent image quality and is considered superior to CUS in identifying cerebellar lesions and white matter injury 15 . However, MRI is expensive and its clinical use in NICUs is limited because of logistic and safety issues 1 . CUS on the other hand is relatively cheap, directly available and allows serial bedside imaging.…”

Cranial ultrasound (CUS) is a reputable tool for brain imaging in critically ill neonates. It is safe, relatively cheap and easy to use, even when a patient is unstable. In addition it is radiation-free and allows serial imaging. CUS possibilities have steadily expanded. However, in many neonatal intensive care units, these possibilities are not optimally used. We present a comprehensive approach for neonatal CUS, focusing on optimal settings, different probes, multiple acoustic windows and Doppler techniques. This approach is suited for both routine clinical practice and research purposes. In a live demonstration, we show how this technique is performed in the neonatal intensive care unit. Using optimal settings and probes allows for better imaging quality and improves the diagnostic value of CUS in experienced hands. Traditionally, images are obtained through the anterior fontanel. Use of supplemental acoustic windows (lambdoid, mastoid, and lateral fontanels) improves detection of brain injury. Adding Doppler studies allows screening of patency of large intracranial arteries and veins. Flow velocities and indices can be obtained. Doppler CUS offers the possibility of detecting cerebral sinovenous thrombosis at an early stage, creating a window for therapeutic intervention prior to thrombosis-induced tissue damage. Equipment, data storage and safety aspects are also addressed. Video LinkThe video component of this article can be found at

“…Existen pocos estudios publicados al respecto, pero todos ellos muestran unos resultados excelentes, ya que consiguen completar el estudio con buena calidad de las imágenes en un alto porcentaje de los casos 4---8 y demuestran que el procedimiento es seguro, tanto en RN a término como en prematuros cuando se realiza a una edad corregida próxima a la edad de término 4,9,10 .…”
