The frontal skull Hounsfield unit value can predict ventricular enlargement in patients with subarachnoid haemorrhage.

Sci Rep 2018 07 5;8(1):10178. Epub 2018 Jul 5.

Department of Neurosurgery, Hanyang University Guri Hospital, 153 Gyeongchun-ro, Guri, Gyonggi-do, Korea.

Hydrocephalus is a common complication following subarachnoid haemorrhage (SAH) arising from spontaneous aneurysm rupture. The Hounsfield unit (HU) value from computed tomography scans may reflect bone mineral density, which correlates with body mass index, which in turn is related to post-SAH ventricle size changes. We herein investigated potential associations between frontal skull HU values and ventricle size changes after SAH. Read More

Relationship between the extent of T2 lesions and the onset of secondary progression in multiple sclerosis.

Eur J Neurol 2007 Nov;14(11):1210-5

Department of Neurology, University Medical Centre Groningen, University of Groningen, Groningen, The Netherlands.

Patients with relapsing-remitting multiple sclerosis (MS) are at risk of converting to a secondary progressive disease course. To assess the relationship between brain magnetic resonance imaging (MRI) findings and onset of secondary progression, we reanalyzed the initial brain MRI scans of 90 relapsing-remitting MS patients, who were clinically followed up for at least 10 years (median 14 years) after their scan, for the number and volume of T2 lesions, and for two measures of brain atrophy (bicaudate ratio and third ventricle width). The relationship to development of secondary progression was studied with Cox regression models and Kaplan-Meier survival analyses. Read More

Thresholds for cerebral ischemia after severe head injury: relationship with late CT findings and outcome.

J Neurotrauma 1996 Jan;13(1):17-23

Division of Neurosurgery, Medical College of Virginia, Richmond, USA.

Cerebral ischemic insults in at least 30% of severely head injured patients at a very early stage following trauma and are associated with early death. To date, the threshold for ischemia of 18 mL/100g/min used in human head injury studies has been adopted from animal studies (by temporary occlusion of the middle cerebral artery). Since the traumatized brain becomes more susceptible to irreversible damage if accompanied by ischemia one may question whether the threshold for ischemic vulnerability is higher than 18 mL/100 g/min.
