Paul Broca's historic cases: high resolution MR imaging of the brains of Leborgne and Lelong.
In 1861, the French surgeon, Pierre Paul Broca, described two patients who had lost the ability to speak after injury to the posterior inferior frontal gyrus of the brain. Since that time, an infinite number of clinical and functional imaging studies have relied on this brain-behaviour relationship as their anchor for the localization of speech functions. Clinical studies of Broca's aphasia oft...

Introduction: All of the Imaging modalities have advantages and disadvantages alone. So if we want to have the best and perfect image, combining these modalities produces something we desired. PET-MR images consist of morphologic and metabolic data. MRI and PET provide high spatial and contrast resolution and high sensitivity and molecular information respectively. Hybrid PET-...
متن کاملSubcortical damage and white matter disconnection associated with non-fluent speech.
Sir, In a recent paper published in Brain, Dronkers and colleagues (2007) re-examined the brain damage in two historic patients of P. Paul Broca, Leborgne and Lelong, who had lost the ability to speak following brain damage. The observation of these cases lead Broca to suggest that the left inferior frontal lobe (later coined Broca’s area) is the crucial lesion location associated with acquired...
متن کاملSWI: Probe for neuroradiologists
Susceptibility-weighted imaging (SWI) has continued to develop into a powerful clinical tool to visualize venous structures and iron in the brain and to study diverse pathologic conditions. It is a new art which evaluates and exploits the properties of blood, iron and other tissues. It is a magnitude or filtered phase images or combination of both, obtained with high-resolution 3D fully velocit...
