ABSTRACT

Introduction: The three-dimensional balanced fast field echo (3D b-FFE T2) technique provides the visualization of cerebral anatomy with more detail than conventional techniques for the study of hydrocephalus, III and IV ventricular pathology, cerebral aqueduct and other midline brain structures. Objective: To describe imaginological findings by magnetic resonance of anatomy and some intracranial lesions of midline using 3D b-FFE T2 sequences. Materials and methods: A descriptive case series was developed on nine individuals of different age groups from Medellin, Colombia, in which the midline pathology was evaluated through the 3D b-FFE T2 technique during 2014. Results: Four patients with analysis by conventional T1 and T2 spin echo or turbo spin echo and 3D b-FFE T2 techniques of the III ventricle, cerebral aqueduct, basal cisterns and their content were selected. In addition, three cases of obstructive hydrocephalus, a case with ventriculostomy, one with communicating hydrocephalus and two cases of cerebral vascular malformations evaluated with 3D b-FFE T2 technique were included. In all cases, the 3D b-FFE T2 sequence showed in details the structures and intracranial lesions of the midline. Conclusions: The 3D b-FFE T2 sequence is useful to preoperative planning and follow-up of the neuroendoscopic procedures or endoscopic ventriculostomy of the third ventricle. In addition, it permits to visualize the structures and lesions of midline with detail.
