BACKGROUND AND PURPOSE We investigated the residual abnormalities on computed tomography in a series of patients with proven intracerebral hemorrhage to determine whether the type of lesion is related to the site and size of the initial hematoma. METHODS In a partially prospective follow-up study, we studied computed tomographic scans of 42 patients with spontaneous intracerebral hemorrhage a...

BACKGROUND AND PURPOSE MRI can be used to assess structural damage to the brain after aneurysmal subarachnoid hemorrhage. We tuned, validated, and applied k-Nearest Neighbor-based segmentation to quantify cerebral volumes on MRI 6 months after aneurysmal subarachnoid hemorrhage. METHODS After tuning, the accuracy of k-Nearest Neighbor-based segmentation was assessed with manual segmentations....

Cardiac Abnormalities in Subarachnoid Hemorrhage: A Resume • There have been numerous reports demonstrating electrocardiographical changes secondary to subarachnoid hemorrhage, consisting of atrial and ventricular arrhythmias, alterations in QRS configuration, Q-T interval prolongation, T-wave abnormalities, and S-T segment elevation or depression. Abnormalities of cardiac muscle and subendocar...

Background and Purpose—MRI can be used to assess structural damage to the brain after aneurysmal subarachnoid hemorrhage. We tuned, validated, and applied k-Nearest Neighbor-based segmentation to quantify cerebral volumes on MRI 6 months after aneurysmal subarachnoid hemorrhage. Methods—After tuning, the accuracy of k-Nearest Neighbor-based segmentation was assessed with manual segmentations. N...

In a consecutive series of 473 patients admitted within 72 hours after a subarachnoid hemorrhage, 91 (19%) had hydrocephalus on the initial computed tomogram. Consciousness was unimpaired in 25 of the 91 (28%). In 11 more patients acute hydrocephalus developed within 1 week after subarachnoid hemorrhage. Thirty-eight (8%) of all 473 patients subsequently showed clinical deterioration because of...

Introduction: Intraventricular Haemorrhage is the most common forms of brain injury in preterm neonates1, more commonly seen smallest and neonates contributing to mortality, morbidity during time stay hospital. IVH among VLBW with incidence around 20-25% out which 2/3rd are mild moderate severity [grade 1-2]. Objective: To study intraventricular hemorrhage neonates. Methods: This a hospital bas...

the right ventricle (rv) is a complex structure with abstruse function that reveals important differences when compared to the left ventricle (lv), so it cannot be described as a simple geometric form and achromatic physiology. as an inference from this fact, in the present review, we aim to describe rv structure including the embryology, anatomy, and physiology and present a functional, hemody...

INTRODUCTION Non-aneurysmal spontaneous subarachnoid hemorrhage is characterized by an accumulation of a limited amount of subarachnoid hemorrhage, predominantly around the midbrain, and a lack of blood in the brain parenchyma or ventricular system. It represents 5% of all spontaneous subarachnoid hemorrhage cases. In spite of extensive investigation, understanding of the mechanisms leading to ...

BACKGROUND AND PURPOSE CT is a ubiquitous, efficient, and cost-effective method to evaluate pediatric ventricular size, particularly in patients with CSF shunt diversion who often need emergent imaging. We therefore sought to determine the minimum dose output or CT dose index required to produce clinically acceptable examinations. MATERIALS AND METHODS Using a validated noise insertion method...

OBJECTIVE To determine the relation of neonatal cranial ultrasound abnormalities to autism spectrum disorders (ASD) in low birth weight (LBW) adult survivors, a population at increased ASD risk. STUDY DESIGN This is a secondary analysis of a prospectively-followed regional birth cohort of 1105 LBW infants systematically screened for perinatal brain injury with cranial ultrasound in the first ...
