As part of this protocol, a non-contrast brain computed tomography (CT) examination is performed (1,2) and its interpretation is achieved by experienced
neuroradiologists, who in a first step must establish if there are no contraindications for the t-PA administration based on the provided images.
- Investigators at California-based non-profit pediatric academic medical center Children's Hospital Los Angeles (CHLA), led by
neuroradiologist Benita Tamrazi, MD, have determined that in children receiving gadolinium as a contrast agent to enhance MRI examinations, signal changes attributed solely to deposition of this material in the brain are not dependent on the amount of gadolinium administered, the organization said.
Interobserver agreement between senior radiology resident, neuroradiology fellow, and experienced
neuroradiologist in the rating of Alberta Stroke Program Early Computed Tomography Score (ASPECTS).
These patterns were even present among people with idiopathic generalised epilepsies, a type of epilepsy characterised by a lack of any noticeable changes in the brain, such that typically an experienced
neuroradiologist would not be able to see anything unusual in their brain scans.
Dr Johann du Plessis, consultant
neuroradiologist said: "We have added a new MRI scanner to the unit which means we are now able to provide significantly more scanning time per week which will help us to provide a better service for our patients."
However, even in countries such as the US, only 5% of eligible patients receive this treatment [8] due to geographic distances to primary stroke centers and the limited availability of vascular neurologists and
neuroradiologist that after a complete neurological and radiological assessment define if a patient is eligible to receive this treatment.
A brain computerized tomography (CT) scan without contrast (Figure 1) and CT angiogram (CTA) of the neck (Figure 2) were normal as read by an experienced
neuroradiologist. His echocardiogram was also normal.
Ms Sprakel toured the new department with Health Ministry Under-Secretary Dr Aysha Buaneq, financial and technical affairs Under-Secretary Dr Maher Al Onais and SMC radiology chairwoman and consultant
neuroradiologist Dr Suzanne Abbas.
The use of a mobile stroke unit, in which paramedics are in contact with a
neuroradiologist and stroke physician at a hospital, may be able to save valuable time in responding to stroke patients.
Sorensen served until recently as president and CEO of Siemens Healthcare North America, and is a
neuroradiologist.
When
neuroradiologist Jerry Jarvik performed a second MRI three years after first scanning pain-free adults, he found very few new abnormalities.
A
neuroradiologist - following the procedure on a monitor - inserts a micro-catheter in a blood vessel in the groin and threads it through the aorta and carotid artery into the blocked vessel in the brain.
