Cerebral Cavernous Malformations: Typical and Atypical Imaging Characteristics
Kuroedov, D; Cunha, B; Pamplona, J; Castillo, M; Ramalho, JCavernous malformations (CMs) are benign vascular malformations that maybe seen anywhere in the central nervous system. They are dynamic lesions, growing or shrinking over time and only rarely remaining stable. Size varies from a few millimeters to a few centimeters. CMs can be sporadic or familial, and while most of them are congenital, de novo and acquired lesions may also be seen. Etiology is still unknown. ...
Signal Intensity Change on Unenhanced T1-Weighted Images in Dentate Nucleus Fol...
Ramalho, J; Semelka, RC; AlObaidy, M; Ramalho, M; Nunes, RH; Castillo, MOBJECTIVES: To evaluate the impact of previous administration of gadodiamide and neural tissue gadolinium deposition in patients who received gadobenate dimeglumine. METHODS: Our population included 62 patients who underwent at least three administrations of gadobenate dimeglumine, plus an additional contrast-enhanced last MRI for reference, divided into two groups: group 1, patients who in addition to gadobena...
Gadolinium-Based Contrast Agent Accumulation and Toxicity: an Update
Ramalho, J; Semelka, RC; Ramalho, M; Nunes, RH; Alobaidy, M; Castillo, MIn current practice, gadolinium-based contrast agents have been considered safe when used at clinically recommended doses in patients without severe renal insufficiency. The causal relationship between gadolinium-based contrast agents and nephrogenic systemic fibrosis in patients with renal insufficiency resulted in new policies regarding the administration of these agents. After an effective screening of patie...
Toxic and Metabolic Myelopathies
Ramalho, J; Hoffmann Nunes, R; da Rocha, AJ; Castillo, MMyelopathy describes any neurologic deficit related to the spinal cord. It is most commonly caused by its compression by neoplasms, degenerative disc disease, trauma, or infection. Less common causes of myelopathy include spinal cord tumors, infection, inflammatory, neurodegenerative, vascular, toxic, and metabolic disorders. Conditions affecting the spinal cord must be recognized as early as possible to preven...
Evidence Levels for Neuroradiology Articles: Low Agreement Among Raters
Ramalho, J; Tedesqui, G; Ramalho, M; Azevedo, RS; Castillo, MBACKGROUND AND PURPOSE: Because evidence-based articles are difficult to recognize among the large volume of publications available, some journals have adopted evidence-based medicine criteria to classify their articles. Our purpose was to determine whether an evidence-based medicine classification used by a subspecialty-imaging journal allowed consistent categorization of levels of evidence among different rat...
