The reflected ultrasound is received by the probe, transformed into an electric impulse as voltage, and sent to the engine for signal processing and conversion to an image on the screen. The depth reached by the ultrasound beam is dependent on the frequency of the probe used. The higher the frequency, the lesser the depth reached. [9]
There is no evidence to support the use of ultrasound for the treatment of low back pain, [24] and current clinical guidelines recommend that ultrasound is not used for this condition. [25] In a critical review, it was demonstrated that therapeutic ultrasound was effective in improving pain, function, and cartilage repair in knee osteoarthritis.
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
For example, gout in ankles or gout in knee joints may also occur. ... hard deposits. It can lead to pain, soft tissue damage, and joint deformities. ... ultrasound, or CT scan to visualize uric ...
A thrombus may not be evident in the scan. Also a vein lumen may show echoes without the presence of a thrombus. The location of the thrombus and its detail will inform of the seriousness of the condition. In a deep vein thrombosis (DVT), or in a superficial vein thrombosis where the thrombus is floating, an emergency situation will be indicated.
This method of medical ultrasound therapy can be used for various types of pain relief and physical therapy. In physics, the term "ultrasound" [1] applies to all acoustic energy with a frequency above the audible range of human hearing. The audible range of sound is 20 hertz – 20 kilohertz. Ultrasound frequency is greater than 20 kilohertz.
Cryoneuralysis has been used to relieve pain after thoracotomy, mastectomy, and knee or shoulder arthroplasty. [1] [2] Combined with ultrasound imaging, the procedure can be administered using a hand-held device in an office, and appears to provide an expedient, safe, and nonpharmacological option for treating various chronic pain conditions.

Computed tomography (CT) scans cannot directly diagnose bone marrow edema, but it is sometimes used to supplement MRI scans for differential diagnosis. It is due to its ability to show any lesions or fractures in trabecular, subchondral or chondral structures, which aids physicians to understand if there are any underlying bone pathologies ...
