A head computed tomography (CT) scan was obtained immediately to rule out a stroke. Her medical history was significant for coronary heart disease, hypertension, asthma and seizures. Her last seizure was almost 10 years ago. She had taken an anti-epileptic medication in the past and had ...
Arterial dissection is an independent risk factor for ischemic stroke. In this study, we have observed a low utilization of imaging to rule out dissection; there is a suggestion of disparity among the sexes in diagnosis.#Conclusion:The observation from this study involving all hospitals in the ...
Coronary computed tomography angiography (CTA) has evolved as a logistically simple, accurate, and low-risk noninvasive test to diagnose or rule-out CAD (1,4). The negative predictive value of coronary CTA has been reported to be especially high in a broad range of clinical presentations (5,...

The median effective dose ranged from 2 m Sv for a routine head CT (interquartile range, 2–3 m Sv) to 14 m Sv (interquartile range, 9–20 m Sv) for a suspected stroke CT. The variations displayed no discernable pattern and occurred within and across institutions. Therefore, using a ...

Acute stroke PCT provides a rapid and simple means to evaluate cerebral perfusion in patients presenting with acute stroke symptoms, most of whom already undergo unenhanced head CT to rule out intracranial hemorrhage. Indeed, findings of acute cerebral ischemia, however, can be subtle or absent on...
In October 2009 Los Angeles-based Cedars-Sinai disclosed that over the course of 18 months 260 possible stroke victims had received up to eight times the normal radiation dose in a scan procedure to identify blood flow issues in the brain. Once patients began to come forward with symptoms of...
Cardiac catheterization, which also checks the function of heart valves and muscle, takes longer, between 30 minutes and 45 minutes to perform, and requires more than an hour for recovery. Potential complications from the invasive procedure include infection, heart attack and stroke; however, these...
