objective brain abscesses represent organized foci of suppuration within the parenchyma. here we report a 3 month-old girl with a very huge complicated cerebral abscess, and the course of treatment given. the patient's recovery was excellent. the follow up mri showed only subtle porencephalic changes as the only parenchymal sequelae, which may be due to cns plasticity in infants.

PURPOSE To correlate parenchymal brain changes, venous sinus pressure measurements, and outcome in 29 patients with acute dural sinus thrombosis. METHODS A retrospective review of 29 patients with angiographically proved acute dural sinus thrombosis was made from January 1989 to December 1993. MR examinations were performed on either a 0.5- or 1.5-T superconductive scanner in multiple planes....

BACKGROUND AND PURPOSE One major limitation of current functional MR (fMR) imaging is its inability to clarify the relationship between sites of cortical neuronal activation, small parenchymal venules that are in close proximity to these sites, and large draining veins distant from the active parenchyma. We propose to use gradient-echo blood oxygenation level-dependent (BOLD) fMR time courses t...

background controlling parenchymal hemorrhage especially in liver parenchyma, despite the progress in surgical science, is still one of the challenges that surgeons face when trying to save patients’ lives. researchers in the field are challenging to introduce a more effective method. objectives the current study aimed to determine the haemostatic effect of alum [kal (so4)2] and compare it with...

The essence of asthma is impairment of expiratory flow. Expiratory flow requires lung recoil forces to supply the driving pressure and to tether the airways open. Lung recoil forces arise within the parenchymal structures, particularly the air-liquid interface and elastin. Lung recoil is mainly elastic, but shows dissipative properties and contractility, and may be changed by volume history, ti...
