Background and Purpose— Our goal was to evaluate whether the presence of a low signal intensity known as susceptibility vessel sign (SVS) on T2*-gradient echo imaging sequence predictive arterial recanalization early clinical improvement after mechanical thrombectomy. Methods— This observational study based prospective database acute ischemic strokes treated by Inclusion criteria were patients with anterior stroke, diagnosed magnetic resonance imaging, including sequence, Two independent...
Background: Leptomeningeal enhancement (LME) is a key feature of Susac syndrome (SuS) but only occasionally depicted on post-contrast T1-weighted images (T1-WI). Objective: As fluid-attenuated inversion recovery (FLAIR) may be more sensitive, our aim was to assess LME in SuS this sequence. Methods: From 2010 2020, 20 patients with definite diagnosis were retrospectively enrolled multicentre study. Two radiologists independently assessed the number FLAIR and T1-WI acquisitions performed...
The composition of the thrombus influences its retrievability by mechanical thrombectomy.Our study aimed to report on thrombi resistant aspiration, regarding susceptibility vessel sign and histologic composition.This observational was based a prospective database acute anterior circulation ischemic strokes treated thrombectomy. Endovascular first-line strategy aspiration in case failure, combined therapy-rescue performed. positivity (SVS+) or negativity (SVS-) assessed T2* sequences....
Glioblastoma is the most aggressive primary brain tumor, which almost systematically relapses despite surgery (when possible) followed by radio-chemotherapy temozolomide-based treatment. Upon relapse, one option for treatment another chemotherapy, lomustine. The efficacy of these chemotherapy regimens depends on methylation a specific gene promoter known as MGMT, main prognosis factor glioblastoma. Knowing this biomarker key issue clinician to personalize and adapt patient at diagnosis...
Posterior fossa tumors represent two thirds of brain in children. Although progress treatment has improved survival rates over the past few years, long-term memory impairments survivors are frequent and have an impact on academic achievement. The hippocampi, cerebellum cerebellar-cortical networks play a role several systems. They affected not only by location tumor itself its surgical removal, but also supratentorial effects complementary treatments, particularly radiotherapy. IMPALA study...
The changes in pulmonary volume taking place during respiration are accompanied by the opening and closing of alveoli, with number alveoli open, at same transpulmonary pressure (TPP) differing, depending on whether lung is insufflated or deflated.Seventy 344 Fischer rats divided into five groups. Group 1 lungs were fixed instilling 10% formalin through trachea to a 25 cm H2O. next four groups air-filled via artery: group 2 inflation 10 H2O TPP; 3 20 cm. 4 5 deflation and, therefore, inflated...
<h3>BACKGROUND AND PURPOSE:</h3> The ICA is the most common site of cervical artery dissection. Prompt and reliable identification mural hematoma warranted when a dissection clinically suspected. purpose this study was to assess capacity standard DWI sequence acquired routinely on brain detect dissecting related dissections. <h3>MATERIALS METHODS:</h3> This retrospective cohort 110 patients younger than 55 years age (40 women; mean age, 46.79 years) admitted at acute phase neurologic...
The resistance to airflow that develops in most obstructive processes takes place the small airways. aim of present paper is describe bronchial hysteresis morphometrically a respiratory cycle model. As working hypothesis, it proposed changes take tract during are related size. Specimen rat lungs were organized into five groups: In first group, filled with liquid fixative 25 cm H2O transpulmonary pressure. following four groups inflated air and fixed through pulmonary artery. Groups 2 3 at 10...
Purpose Although perfusion magnetic resonance imaging (MRI) is widely used to identify pseudoprogression, this advanced technique lacks clinical reliability. Our aim was develop a parameter assessing the hypervascularized fraction of glioblastomas based on volume analysis dynamic susceptibility contrast-enhanced MRI and evaluate its performance in diagnosis pseudoprogression. Methods Patients with primary glioblastoma showing lesion progression first follow-up after chemoradiotherapy were...
FGFR-fused central nervous system (CNS) tumours are rare and usually within the glioneuronal neuronal or paediatric-type diffuse low-grade glioma spectrum. Among this spectrum, FGFR2 fusion has been documented in classified by DNA-methylation profiling as polymorphous neuroepithelial of young (PLNTY), a recently described tumour type. However, fusions have also reported tumours, highlighting overlapping diagnostic criteria challenges.
