We present a technique for automatically assigning neuroanatomical label to each location on cortical surface model based probabilistic information estimated from manually labeled training set. This procedure incorporates both geometric derived the model, and convention, as found in The result is complete labeling of sulci gyri. Examples are given two different sets generated using conventions, illustrating flexibility algorithm. shown be comparable accuracy manual labeling.
To define magnetic resonance (MR) imaging criteria for the diagnosis of cavernous sinus invasion by pituitary adenoma.The MR images obtained in 106 patients (86 female, 20 male; age range, 16-71 years) were reviewed retrospectively two physicians. The standard-of-reference surgical findings. A chi(2) analysis was performed, and sensitivity, specificity, positive predictive value (PPV), negative (NPV) nine groups signs computed.Invasion certain (PPV, 100%) if percentage encasement internal...
Objective. The objective of this study was to compare glucose metabolism and atrophy, in the precuneus cingulate cortex, patients with Alzheimer’s disease (AD) mild cognitive impairment (MCI), using FreeSurfer. Methods. 47 individuals (17 AD, 17 amnestic MCI, 13 healthy controls (HC)) were included. MRI PET images 18 F-FDG (mean injected dose 185 MBq) acquired analyzed FreeSurfer define regions interest hippocampus, amygdala, precuneus, anterior posterior cortex. Regional volumes generated....
To present a new optimition-driven design of optimal k-space trajectories in the context compressed sensing: Spreading Projection Algorithm for Rapid K-space sampLING (SPARKLING).The SPARKLING algorithm is versatile method inspired from stippling techniques that automatically generates optimized sampling patterns compatible with MR hardware constraints on maximum gradient amplitude and slew rate. These non-Cartesian curves are designed to comply key criteria sampling: controlled distribution...
Consciousness is composed of arousal (i.e., wakefulness) and awareness. Substantial progress has been made in mapping the cortical networks that underlie awareness human brain, but knowledge about subcortical sustain humans incomplete. Here, we aimed to map connectivity a proposed network sustains wakefulness analogous default mode (DMN) shown contribute We integrated data from ex vivo diffusion magnetic resonance imaging (MRI) three brains, obtained at autopsy neurologically normal...
A rostrocaudal pathway connecting the temporal and parietal lobes was described in monkeys using autoradiography named middle longitudinal fasciculus (MdLF). Recently, use of diffusion tensor tractography has allowed it to be depicted human volunteers. In present study, a technique fiber dissection used 18 cadaveric brains investigate presence this detail its anatomical relationships. On basis our findings, provides evidence for long horizontal bundle medial arcuate extending superior gyrus....
The combination of optical tissue transparency with immunofluorescence allows the molecular characterization biological tissues in 3D. However, adult human organs are particularly challenging to become transparent because autofluorescence contributions aged tissues. To meet this challenge, we optimized SHORT (SWITCH-H
The so-called Dorello's canal was studied in 32 specimens (16 human cadaver heads) injected with colored latex and fixed formalin (28 specimens) or microscopic ultrastructural methods (four specimens). To avoid the differences usually encountered description of this area, authors preferred to consider a larger space that they have named petroclival venous confluence (PVC). It located between two dural layers: inner (or cerebral) outer osteoperiosteal). PVC quadrangular on transverse section....
Object In this study, the authors used a fiber-dissection technique to describe optic radiation. They focused on morphological characteristics (length and breadth) of structure, its course, relationships with neighboring fasciculi lateral ventricle. Methods The dissected 10 previously frozen, formalin-fixed human brains aid an operating microscope by following fiber dissection described Klingler in 1960. Lateral, inferior, medial approaches were made. radiation, also known as Gratiolet...
Awake craniotomy with intraoperative electric stimulation is a reliable method for extensive removal of low-grade gliomas while preserving the functional integrity eloquent surrounding brain structures. Although fully awake procedures have been proposed, asleep-awake-asleep remains standard technique. Anesthetic contraindications are only limitation this method, which therefore not older patients high-grade gliomas.To describe and assess novel based on hypnosis.We proposed hypnosedation...
Object. The authors studied the heads of 17 adult cadavers and one fetus to clarify anatomy sellar region, particularly lateral boundaries hypophyseal fossa. Methods. Vascular injections microdissection or histological techniques were used in this study. roof cavernous sinuses diaphragma sellae part a single horizontal dural layer that joined two anterior petroclinoid folds. Laterally, direction changed; it became wall sinus dura mater middle cerebral On midline, ballooned toward sella...
Object. The pericallosal arterial complex supplies the callosal and regions, as well anterior two thirds of medial superomedial aspects both hemispheres. It is composed artery (that is, segment cerebral located distal to communicating [ACoA]) median (or third artery), which originates from ACoA. This system was studied in 46 specimens (23 human cadaver heads) injected with colored latex. Methods. After being latex, embalmed, bleached, were aid optic magnification. found be divided into four...
