Ultrasound Guided Injections • Unlike an MRI, an ultrasound exam can be performed during your office visit without any prior authorization from your insurance company or need for scheduling. • Unlike an MRI which can take more than 30 minutes, an ultrasound exam can be performed in a few moments during your office evaluation. • Unlike x-rays and MRI which provide still images, an ultrasound is a dynamic process that can evaluate muscles, tendons, and joints during motion. This can be useful when attempting to diagnose the source of painful motion-related snaps and pops.

Contents: Sonogram vs Ultrasound Sonogram vs. Ultrasound. A sonogram is the image generated during ultrasonography, which is a diagnostic imaging technique that uses ultrasound to visualize anything inside the body. Ultrasound is sound with a frequency above the range audible to humans, about 20 kHz. In common parlance, both words are used to refer to the ultrasonography procedure.
