- An alternative explanation of the origin of the signal in diffusion-weighted MRIPublication . Branco, GI formulated an alternative explanation for the origin of the signal in diffusion-weighted MRI (DWI) and tested it in a simple experimental model using gelatin. My findings indicate that the signal in DWI is influenced by the passage of water from the sol to the gel state, independently of the presence of cell structures or membrane-dependent diffusion.
- Anomalia Congénita Coclear: Tentativa de Relação Embriológica e Anátomo-FuncionalPublication . Maurício, JC; Biscoito, L; Branco, GIn this review of cochlear malformations, 17 cases were studied by CT scan (high resolution-target program) including 10 males and 7 females. The anomaly was bilateral in 12 cases and unilateral in 7 (the latter included 2 Mondini type aplasias and one Michel). The cochlear malformation (whose most frequent expression was the cochlear hypoplasia with 1 or 1 1/2 spires-65% of the cases) was associated to semicircular canals and/or vestibular aqueduct anomaly in 82% of the patients; it was exclusively of the anterior labyrinth in 18% of the cases. A middle ear malformation coexisted in 29%: in 3 cases with malleoincudal dysmorphy only and with tympanic aplasia in 2 others. These cochlear anomalies with CT expression were discussed considering the embryology, in view of a possible gestational dating, moreover relating to the hipocusia type: perceptive or combined.
