The hyperintense lesion could be due to a cyst or tumor. I have a had a kidney cyst since 2009. The prevailing view is that these intensities are a marker of small-vessel vascular disease and in clinical practice, are . T2 relaxation, also known as spin-spin relaxation or transverse relaxation, refers to the progressive dephasing of spinning dipoles resulting in decay in the magnetization in the transverse plane (M xy).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 .

Radiologists play a valuable role in helping narrow the differential diagnosis by integrating patient history and laboratory test results with key imaging characteristics. Also how common are such findings that are "nonspecific"? Sufficient damage to the axons that course through WMH can cause adequate interference with normal neuronal functions.

I recently had an MRI to rule out a pseudotumor cerebri. PMC As motion, and therefore the local field fluctuations, decreases below the Larmor frequency in tissues and tendons,dipoles that are aligned with the main magnetic field start contributing to T2 relaxation by causing local variations in precession rate. "Nonspecific white matter changes". One of the major challenges associated with the T2 assessment according to the RANO criteria is the differentiation between T2-progress and other causes of T2 signal increase, such as edema, radiation effects, decreased corticosteroid dosing, seizures, postoperative changes, or even ischemic injury. 11, 23 It is still unclear the number of cases in which these causes of T2-signal increase may .

Diagnosis is based on the appearance of the rotator cuff tendons (grading system) and the presence or absence of signs denoting involvement of the subacromial bursa and subacromialsubdeltoid plane. Pathological tissue usually has more water than normal brain so this is a good type to scan to pick this up. This finding has been variously attributed to the presence of fat, muscle, connective tissue, abnormal vascularity, or degenerative changes. MRI found mild scattered foci of abnormal T2 signal are demonstrated in peri ventricular white matter, particularly along frontal convexities. There is mild heterogeneous t2 signal change within the supraspinatus and subscapularis.what does that mean? Can a person have such a finding and still be normal?
