"Nonspecific" usually means cause unclear/many possible causes and often implies "low concern". I am a having a few issues but my main concern is: i recently had a MRI of my lumbar spine to diagnose the severity of my spinal stenosis. My mri states: there is a single region of three foci of t2 prolongation within the white matter. Quant Imaging Med Surg 2020; 10:2030-2065. The hyperintense focus is a bright spot, likely caused by higher than expected water content. For example, a brainstem lesion can cause room spinning sensations and balance problems.

On this Wikipedia the language links are at the top of the page across from the article title. . 2009 Dec;53(6):558. doi: 10.1111/j.1754-9485.2009.02123.x. Would you kindly let me know what this means. In pure water T2 is long, about 3-4 seconds because water molecules move considerably faster than the Larmor frequency. T2 relaxation occurs due to tissue-particular characteristics, primarily those that affect the rate of movement of protons, most of which are found in water molecules. Also how common are such findings that are "nonspecific"? This is related in part to the slower motion of protons both in macromolecules as well as water molecules attracted to the surface of the macromolecule. Foci of increased T2 signal intensity were found on brain MR scans in 16 (59%) of 27 healthy elderly volunteer subjects, ages 63 to 86 years old.

Please note, we cannot prescribe controlled substances, diet pills, antipsychotics, or other abusable medications. Following a radiofrequency pulse, this form of relaxation occurs with the time constant T2, where T2 is the time it takes for the transverse magnetization vector to decay to 1/e or 37% of its initial magnitude. A hyperintensity or T2 hyperintensity is an area of high intensity on types of magnetic resonance imaging (MRI) scans of the brain of a human or of another mammal that reflect lesions produced largely by demyelination and axonal loss. 3 How long does supraspinatus tendinopathy take to heal? It also found the following: There is a focus of uniform T2 prolongation in the medial lower pole of the right kidney measuring 20 mm in diameter. [6], Postmortem studies combined with MRI suggest that hyperintensities are dilated perivascular spaces, or demyelination caused by reduced local blood flow. This is likely your case by use of the word "minimal." This report means that this tissue has different characteristics (has more water) than the surrounding tissue.

Misdiagnosis of spinal subacute combined degeneration in a patient with elevated serum B12 concentration and sensory deficit level. FInstP PJAOBEPFIPSM, CSci JWMFIPEM. Usually this is due to an increased water content of the tissue. Causes including simple MR artefacts, trauma, primary and secondary tumours, radiation myelitis and diastematomyelia were discussed in Part A. Areas of new, active inflammation in the brain become white on T1 scans with contrast.
