The most significant impact of magnetic resonance neurography is on the evaluation of the large proximal nerve elements such as the brachial plexus (the nerves between the cervical spine and the underarm that innervate shoulder, arm and hand), [9] the lumbosacral plexus (nerves between the lumbosacral spine and legs), the sciatic nerve in the pelvis, [10] as well as other nerves such as the ...
These form an aponeurosis, a broad flat tendon that covers the upper three-quarters of the muscle. From the inner surface of the aponeurosis, many muscle fibers originate. Some additional fibers arise from the tendon of the gluteus maximus muscle, and from the septum between the vastus lateralis and short head of the biceps femoris.
Whole body imaging (WBI) refers to the display of the entire body in a single procedure. In medical imaging , it may refer to full-body CT scan or magnetic resonance imaging . It may also refer to different types of Full body scanner technologies used for security screening such as in airports.

The term "diagonalize" refers to the three components of the matrix along a diagonal from upper left to lower right (the components with red subscripts in the matrix at the start of this section). The variables a x 2 {\displaystyle ax^{2}} , b y 2 {\displaystyle by^{2}} , and c z 2 {\displaystyle cz^{2}} are along the diagonal (red subscripts ...
The thickness of the fascia can give problems when any inflammation present in the leg has little room to expand into. Blood vessels and nerves can also be affected by the pressure caused by any swelling in the leg. If the pressure becomes great enough, blood flow to the muscle can be blocked, leading to a condition known as compartment ...
Modern 3 Tesla clinical MRI scanner.. Magnetic resonance imaging (MRI) is a medical imaging technique mostly used in radiology and nuclear medicine in order to investigate the anatomy and physiology of the body, and to detect pathologies including tumors, inflammation, neurological conditions such as stroke, disorders of muscles and joints, and abnormalities in the heart and blood vessels ...
Usually, in this case, motor function of the lower leg will not be impaired. This is a key distinction between saphenous nerve neuropathy and lower back radiculopathy. Saphenous nerve neuropathy only demonstrates sensory alterations, while lumbar radiculopathy will affect the motor, sensory, and deep tendon reflexes of the lower leg. [6]
