Magnetic resonance imaging (MRI) is a type of testing used to diagnose and track treatment of various diseases without using radiation. Instead, MRIs use magnets and radio waves to form the images.
MRIs have other advantages over computed tomography (CT) scans and x-rays. The most important advantage is that MRIs can provide a greater contrast between the bones and the soft body tissues, like ligaments and muscles.
X-rays have been around for more than a century now; MRIs are definitely the new kids on the block. They won’t replace x-rays but they can improve a doctor’s ability to diagnose and treat patients.

A new study in which researchers are using MRI to spot bleeding in the heart after stent surgery is giving new hope to heart attack patients.
When the artery feeding blood to the heart is blocked a heart attack occurs. The blockage not only stops the flow of blood to the heart muscle, it also stops the hearts oxygen.
In most cases when a blockage is found a metal stent is placed in the artery.
Until recently researchers were unable to tell if the patients were bleeding into the heart after the stent surgery.
In the new study, researchers used (magnetic resonance imaging) …read more

This is of great importance. Realizing the signs and symptoms of a stroke can make the difference between life an death and between resolving symptoms and forever disabilities.
tPA is only administered if the symptoms are within a 3 hour window at most ER’s. What happens if you present saying your symptoms started yesterday? Well, first of all you are not fast tracked and wait as a stage or grade 2 patient. Next, you are not eligible to receive any clot busting type medications.
Aldo of importance, how you arrive at the hospital. Yes, believe it or not it does make a …read more

Duke University bioengineers can compensate for the thickness of the skull to see in real-time the arteries within the brain that most often clog up and cause strokes using new 3-D ultrasound technology they designed. This is believed to be the first of its kind- to see past the skull and actually view the major arteries.
This could save many of lives, in emergent and routine situations. What are the real benefits?
The 3-D ultrasound has the benefit of being less expensive and faster than the traditional methods of assessing blood flow in the brain — MRI or CT scanning, Ivancevich said. …read more
