After mri,on lower spine what does clinical correlation mean
Arachnoiditis is inflammation of the the leptomeninges (arachnoid and pia mater). These structures wrap the surface of the brain and spinal cord. When they are inflamed, whatever the underlying cause, gadolinium injection during an MRI scan causes enhancement of the leptomeninges on T1 weighted images. Many different health problems may cause arachnoiditis (from tuberculosis to carcinomatosis to autoimmune diseases). So, strictly speaking, arachnoiditis on an MRI means the leptomeninges enhance.
MRI stands for magnetic resonance imaging.
Magnetic action on hydrogen ions - is the simplest and shortest answer to this question. MRI is distinct from other forms of radiography in that no radiation is used. MRI images often provide the best definition of structures. In some cases, contrast enhancement (e.g. with gadolinium) is needed for the best definition (e.g. certain tumors, etc.).
It means that they could find nothing wrong on the MRI.
Inhomogeneous enhancement means that the contrast medium or tracer was picked up unevenly by the area being studied. The clinical meaning will depend on the body part as well as on your history and physical.
It means that they could find nothing wrong on the MRI.
