In the study, New technologies applied to the ultrasound diagnosis of sports injuries, José Fernando Jiménez Díaz compares ultrasound images taken by two different portable ultrasound devices. As a result, the new ultrasound device with 3D technology provided a more defined image of the lesion than the conventional ultrasound device. The use of this new technology will not only produce a superior image, but will also allow doctors to develop a reliable diagnosis and provide effective treatment. Díaz, a specialist from the University of Castilla La Mancha specializing in sports medicine, compared Ultrasound images of five different types of musculoskeletal injuries from two different high-definition ultrasound devices. The two devices used in the study were the traditional US-A model and the new technological device US-B. The US-B system included harmonic imaging, real-time ultrasound, panoramic view, 3D imaging and virtual convex. The images of the five different subjects included muscle contusion, muscle strain, patellar tendonitis, calcified patellar tendonitis, and partial rupture of the medial knee ligament. According to Diaz (2008), the results of the study showed that the images of the new 3D technology were much clearer and more defined than the traditional US device. In muscle contusions and tendon injuries the definitions of hemorrhagic areas increased significantly. Images of chronic ligament injuries showed where scar tissue had formed and provided better visualization of the damaged tissue. Finally, the new US-B system allowed the ultrasound specialist to see the contents of the bursa and the thickness of the walls more clearly. This new 3D technology is not intended to provide the patient with a beautiful image of the lesion, but to provide image detail so that doctors can make an accurate diagnosis and provide reliable treatment. These intraoperative ultrasounds, a new branch of scanning lesions, allow in some cases to avoid surgery, which was previously inevitable with traditional ultrasounds. With any sports injury, an athlete's goal is to recover quickly and safely so they can return to the field. In my opinion, who wouldn't want this type of 3D technology as a tool for doctors to use? It is a great tool for doctors to use when deciding on a diagnosis. I believe athletes would feel more comfortable if high-definition ultrasound were used, especially if surgery can be ruled out. During my college years, I worked as a student coach in the athletic training room for two years and saw my share of injuries.
