MRI is a technique that uses magnetic field and computer-generated sound waves to obtain detailed images of organs and tissues in our body. The magnetic field inside the MRI machine temporarily realigns water molecules in your body. The aligned molecules produce faint signals with radio waves, and create cross-sectional MRI images. 3D images can be produced with MRI by viewing the organ or tissue in various angles.
This noninvasive imaging technique gives high-resolution images of our body tissues which helps identify different health issues. MRI is the most frequently used method to obtain images of the brain and spinal cord. Other common organs and tissues imaged with MRI include heart, blood vessels, internal organs (liver, kidney, pancreas etc.), bones and joints, as well as the breasts.
However, since MRI uses powerful magnets to generate a strong magnetic field, any presence of metal in your body can be attracted to the magnet and can be a safety hazard. Metal can also distort the MRI image. Tattoos or permanent makeup might contain metal and might affect the MRI result. Report to the doctor if you are pregnant or breast-feeding, as the effects of the contrast material that has to be injected are still not well understood.
Patellar tendonitis, also known as jumper’s knee, is the inflammation of the patellar tendon, which connects your knee cap to your shin bone. This condition can weaken the connective tissue and can possibly lead to tears in your tendon. Possible causes of the inflammation of the patellar tendon include practicing repetitive movements, overusing the tendon or adding too much pressure to your tendon repeatedly.
Knee pain is one of the most common symptoms of patellar tendonitis. If you feel pain especially when jumping, running, stretching and bending your leg; tenderness or swelling at the lower part of your knee cap, it is likely that your patellar tendon is inflame. Some symptoms resemble other medical condition, X-ray is one of the best ways to diagnose patellar tendonitis.
Once diagnosed for patellar tendonitis, it is important to stop the activities that caused the problem until fully recovered. Other treatments such as applying ice packs to your knees helps reduce inflammation, and shockwave therapy speeds up the healing process.
