MRI’s Explained – Open vs. Closed Operating Systems

Magnetic resonance imaging (MRI) didn’t start as the technology we now commonly know. Researchers Felix Bloch and Edward Purcell first discovered the magnetic resonance phenomena in 1946 and later harnessed the abilities of magnetic resonance to analyze chemicals, leading to their Nobel Prize in 1952. Later on, scientists discovered the same technique could be used to visualize different human tissues. By 1973, aided by the rapid technological progression of computers, researchers developed the MRI that we now use today. Then, in 2003, the MRI led to another Nobel Prize, this time awarded to researchers Paul Lauterbur and Peter Mansfield for developing MRI as a diagnostic tool. What is an MRI? An MRI uses a strong magnetic field and directs the field at a specific area of the object or person of interest. As the magnetic field enters different tissues and fluids within the body, hydrogen atoms become excited similarly to how a smaller magnet becomes excited as a larger magnet inches closer. Depending on the tissue or fluid that the hydrogen atoms are in, the atoms return to a resting state at different rates as the magnetic field is turned on and off several times. This allows a computer to analyze the [...]

An improved Approach to Tendonitis Treatment: Platelet-Rich Plasma Injections

Platelet-rich-plasma (PRP) injections have been making headway in medicine for the last decade due to their effective treatment of common tendonitis pain. While PRP injections are most often used to heal the chronically inflamed tendons of your ankle, knee, and elbow, they have also been used to treat fractures, tears, and arthritis as well. The procedure is most popular among active individuals and is often utilized by professional athletes, such as Tiger Woods and Rafael Nadal to name a few. We all know the road to recovery from a chronic overuse injury can often be an irritating one, and while this treatment may be a solution to your problem, let’s first go over what this procedure is as well as the pros and cons. The Procedure: Platelet-rich plasma injections are injections of, you guessed it, platelets directly into the injured area. To do this, the nurse first draws your blood. After a quick process to separate the blood into its components, the doctor then takes the platelet portion and injects the platelets directly into the area of interest. Why platelets? While platelets are commonly known for their blood clotting effects, platelets also contain a high concentration of growth factors that help speed [...]
