A hamstring (/ ˈ h æ m s t r ɪ ŋ /) is any one of the three posterior thigh muscles in human anatomy between the hip and the knee: from medial to lateral, the semimembranosus, semitendinosus and biceps femoris.
Bruising due to strained hamstring; horizontal lines show where bandage was. A grade three hamstring strain is a severe injury. There is an immediate burning or stabbing pain and the individual is unable to walk without pain. The muscle is completely torn and there may be a large lump of muscle tissue above a depression where the tear is.
From their common origin at a joint or tendon, ganglion cysts may form in a wide range of locations. Rarely, intraosseous ganglion cysts occur, sometimes in combination with a cyst in the overlying soft tissue. [6] [16] Rare cases of intramuscular ganglion cysts in the gastrocnemius muscle of the calf have been reported.
The Dallas Morning News reports Prescott suffered a partial avulsion of his right hamstring tendon, an injury severe enough that team officials are trying to determine if he needs surgery on the ...
Real-time 3D ultrasound allows muscles, nerves and vessels to be clearly identified while a needle or catheter is advanced under the skin. This type of ultrasound is capable of imaging the needle regardless of the plane of the image, which is a substantial improvement over 2D ultrasound.
B-Mode image and corresponding raw ultrasound signal. Traditionally, ultrasound B-Mode imaging has been designed for allowing a visual evaluation of human organs and their features by clinicians; however, this implies that the huge quantity of information carried by ultrasound signals is processed and significantly reduced for visualization purposes.
The success of lithotripsy depends on the size and location of the stone, and the patient's age. [10] Oncology. Ultrasound can ablate tumors or other tissue non-invasively. [4] This is accomplished using a technique known as high intensity focused ultrasound (HIFU), also called focused ultrasound surgery. This procedure uses generally lower ...
Synthetic aperture ultrasound (SAU) imaging is an advanced form of imaging technology used to form high-resolution images in biomedical ultrasound systems. Ultrasound imaging has become an important and popular medical imaging method, as it is safer and more economical than computer tomography (CT) and magnetic resonance imaging (MRI).
