New Ways To Predict Stroke Attacks

Recommend to others!

Novel research conducted by the researchers from the University of Calgary’s HBI, displays that using the CT scan, the doctors could forecast, if the patients who have earlier faced minor stroke or transient ischemic attack, are at threat for another severe attack.  This significant information can help the doctors take decision if stronger medicines should be given to the patients to prevent prospect strokes, or if the patient can be sent to his home safely. Presently the doctors make use of brain MRI to forecast if the patient is at elevated threat for a second stroke.

But most of the times these MRI scans might not be available immediately for the population of Canada. The study was conducted to ascertain if the CT scans would be effective in forecasting prospect stoke just like the MRI scans. Most of the physicians do not have access to the MRI scans so they cannot access what is going inside the patient’s brain. Therefore this research can allow the medical interventions to be more exclusively available than just at the specialized MRI centers.  In order to ascertain the stroke risk, the researchers have used an injection of dye to see the blood vessels which run from the heart to the brain.

This test is called the CT angiogram and it can be easily administered as a part of the regular CT scan. The doctors found that the patients who showed an evidence of narrowed vessel or blockages on their CT scan were at an elevated threat of frequent stroke. Additionally they also discovered that this test was capable of predicting the frequency of stroke with the similar preciseness like the MRI scan. Even the specialized centers which have MRI machines, often delay in getting the patient for the MRI scan. So this CT scan might have immediate impact and doctors are using this tool to aid the patients.
