Basic principles and technique of diffusion-weighted imaging and diffusion tensor imaging.

CONCLUSION: Diffusion-weighted MRI is an established technique for the assessment of pathological processes. Although DWI is mainly applied in stroke diagnostics, it is increasingly being used to detect and characterize various lesions in the brain as well as in the whole body. With new sequence techniques imaging artefacts can be significantly reduced. In addition, DTI allows the reconstruction and 3-dimensional visualization of tissue fibre structure. This method has proven to be clinically important primarily for the depiction of nerve tracts in the brain and spinal cord when planning surgical interventions and radiation therapy.

SUMMARY: "Encephalopathy" is a vague term that encompasses varying definitions, often with a nonspecific clinical presentation and numerous possible pathophysiologic causes. Hence, MR imaging plays a crucial role in the early diagnosis and treatment by identifying imaging patterns when there is limited clinical history in such patients with acute encephalopathy. The aim of this review was to aid in remembrance of etiologies of potentially reversible acute encephalopathic syndromes on MR imaging. The differential includes vascular (reversible cerebral vasoconstriction syndrome, transient global amnesia, disseminat...

This study aimed to further evaluate the prognostic role of age in a homogenously treated patient cohort. METHODS: The study includes 132 IDH-wildtype glioblastoma patients treated between 2013 and 2017 with open resection followed by radiotherapy with concomitant and maintenance temozolomide. Patients were dichotomized into a non-elderly (

ConclusionOur extensive review favors MRI, CT, and prolonged EEG monitoring to rule out other differentials and showed that initiation of corticosteroid therapy and antiepileptic treatment were helpful in the resolution of symptoms and prevent recurrences. Therefore, future studies should be focused on early identification and management guidelines for SMART syndrome.

(University of Montreal Hospital Research Centre (CRCHUM)) For people with a brain arteriovenous malformation (AVM), a congenital vascular system defect, fate has a name: stroke. To avoid this risk, patients sometimes undergo interventions to remove the malformation. But is this very beneficial? Not necessarily. According to an international clinical trial, co-directed by researchers from the University of Montreal Hospital Research Centre (CRCHUM), interventional treatment--by neurosurgery, neuroradiology or radiation therapy--could be more dangerous than the disease itself.

CONCLUSION Bolus human albumin 5% was not superior to bolus ringer acetate in maintaining systemic or mesenteric oxygen delivery in elective major upper gastrointestinal cancer surgery, despite the administration of larger volumes of trial fluid in the ringer acetate group. No significant difference was seen in fluid-related complications or LOS. TRIAL REGISTRATION Identifier: 2013-002217-36.

Parallel opposed lateral (POL) portals have been adopted as the mainstay radiation therapy technique for early-stage carcinoma of the glottis. Although the use of POL has been associated with excellent control rates and tolerability, the partial inclusion of carotid arteries (CAs) in the high dose regions of the fields has been shown to lead to an increased long-term risk of carotid stenosis and hemorrhagic stroke. Many researchers have proposed the utilization of three-dimension conformal therapy (3DCRT) or Intensity-modulated radiation therapy (IMRT) as viable carotid-sparing techniques via reductions to the mean and max...
