  2. Focused ultrasound - Wikipedia

    en.wikipedia.org/wiki/Focused_ultrasound

    These procedures generally use lower frequencies than medical diagnostic ultrasound (from 0.7 to 2 MHz), but higher the frequency means lower the focusing energy. HIFU treatment is often guided by MRI. Focused ultrasound may be used to dissolve kidney stones by lithotripsy. Ultrasound may be used for cataract treatment by phacoemulsification.

  3. Focused assessment with sonography for trauma - Wikipedia

    en.wikipedia.org/wiki/Focused_assessment_with_s...

    Stratosphere sign is a clinical medical ultrasound finding usually in an eFAST examination that can prove presence of a pneumothorax. The sign is an imaging finding using a 3.5–7.5 MHz ultrasound probe in the fourth and fifth intercostal spaces in the anterior clavicular line using the M-Mode of the machine. This finding is seen in the M-mode ...

    en.wikipedia.org/wiki/Spinal_column

    The number of vertebrae in a region can vary but overall the number remains the same. In a human spinal column, there are normally 33 vertebrae. [3] The upper 24 pre-sacral vertebrae are articulating and separated from each other by intervertebral discs, and the lower nine are fused in adults, five in the sacrum and four in the coccyx, or tailbone.

  5. Magnetic resonance neurography - Wikipedia

    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 ...

  7. Spinal stenosis - Wikipedia

    en.wikipedia.org/wiki/Spinal_stenosis

    Spinal stenosis is an abnormal narrowing of the spinal canal or neural foramen that results in pressure on the spinal cord or nerve roots. [6] Symptoms may include pain, numbness, or weakness in the arms or legs. [1] Symptoms are typically gradual in onset and improve with leaning forward. [1]

  8. Back pain - Wikipedia

    en.wikipedia.org/wiki/Back_pain

    When an entire disc is removed (as in discectomy), or when the vertebrae are unstable, spinal fusion surgery may be performed. Spinal fusion is a procedure in which bone grafts and metal hardware is used to fix together two or more vertebrae, thus preventing the bones of the spinal column from compressing on the spinal cord or nerve roots. [75]

    Subacute combined degeneration of spinal cord; Diagram of the principal fasciculi of the spinal cord. (In subacute combined degeneration of spinal cord, the "combined" refers to the fact that the dorsal columns and lateral corticospinal tracts are both affected, in contrast to tabes dorsalis which is selective for the dorsal columns.)
