Neuromuscular ultrasound refers to a field in medicine in which ultrasound is used to diagnosis and guide treatment for people with neuromuscular diseases.Neuromuscular ultrasound is often combined with electrodiagnosis, and particularly nerve conduction studies and EMG, to improve the accuracy of diagnosis and add anatomic information to the functional information obtained with electrodiagnosis.
New and more precisely defined entities include malignant melanotic nerve sheath tumor (formerly known as melanotic schwannoma) and hybrid nerve sheath tumors. [4] [5] The majority of peripheral nerve tumors are benign tumors of the nerve sheath (usually schwannomas); on rare occasions, they are metastatic tumors or originate from the nerve cells.
Ultrasound-guided peripheral nerve block is a procedure that allows real-time imaging of the positions of the targeted nerve, needle, and surrounding vasculature and other anatomical structures. [16] This visual aid increases the success rate of the block and may reduce the risk of complications.
MR and ultrasound can be used for peripheral nerve imaging. [46] Ultrasound is common for superficial nerves of the upper extremity such as carpal tunnel syndrome. [47] MR imaging is not always reliable in that often the clinical assessment and imaging do not match for peripheral neuropathies. [48]
Proximity to the brachial plexus can be determined using by elicitation of a paresthesia, use of a peripheral nerve stimulator, or ultrasound guidance. [ 11 ] Compared to the interscalene block, the supraclavicular block — despite eliciting a more complete block of the median , radial ulnar and musculocutaneous nerves — does not improve ...
Real-time 3D ultrasound is used during peripheral nerve blockade procedures to identify the relevant anatomy and monitor the spread of local anesthetic around the nerve. Peripheral nerve blockades prevent the transmission of pain signals from the site of injury to the brain without deep sedation, which makes them particularly useful for ...
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.
Damage to the nerves that travel from the spinal cord to the bladder (peripheral nerves) can cause neurogenic bladder, usually the flaccid type. Nerve damage can be caused by diabetes, alcoholism, vitamin B12 deficiency, or genital herpes. Peripheral nerves can also be damaged as a complication of major surgery of the pelvis, such as for ...
