Spinal fMRI
Spinal fMRI
Spinal fMRI (pronounced: /ˈspaɪnəl ɛf ɛm aɪ aɪ/), also known as Spinal Functional Magnetic Resonance Imaging, is a non-invasive imaging technique used to measure and visualize changes in blood flow in the spinal cord. The term "fMRI" stands for functional Magnetic Resonance Imaging, a type of MRI (Magnetic Resonance Imaging) that measures brain activity by detecting changes associated with blood flow.
Etymology
The term "Spinal fMRI" is derived from the words "spinal", referring to the spinal cord, and "fMRI", an acronym for functional Magnetic Resonance Imaging. The term "functional" is used because the technique is used to measure the function of the brain and spinal cord, rather than their structure.
Procedure
During a Spinal fMRI scan, the patient lies on a movable bed that is inserted into the MRI machine. The machine uses a strong magnetic field and radio waves to create images of the spinal cord. These images can show changes in blood flow in the spinal cord, which can indicate areas of activity.
Applications
Spinal fMRI is used in both clinical and research settings. In clinical settings, it can be used to diagnose and monitor conditions such as spinal cord injury, multiple sclerosis, and spinal tumors. In research settings, it can be used to study the function of the spinal cord and how it is affected by various conditions.
