Brain Sonography

The current standard technique for performing neurosonography is through an anterior fontanelle approach with both coronal and sagittal scans. The anterior fontanelle approach provides the most readily accessible view and reveals the best anatomic detail because of the relative large size and acoustic window of the anterior fontanelle. Actually, the exclusive use of transfontanellar scanning can cause some limitations, which might reduce the diagnostic efficacy of cranial ultrasound [1, 2, 3, 4]. The transducer position, being fixed by the location of the anterior fontanelle, may be inadequate in relation to the reflecting interfaces, with practical problems such as “blind” areas, particularly in the upper parieto-occipital region, and an unfavorable angle of incidence with insufficient demonstration of structural details in case of parallel interfaces (i.e., lateral walls of the third ventricle) to the direction of propagation of the ultrasound beam.
