WMH's are also referred to as Leukoaraiosis and are often found in CT or MRI's of older patients. This rate of flipping or transfer of energy between spins or dipoles increases as the frequency of the variation of the local magnetic field approaches the Larmor frequency. Speed of cognitive processes and frontal skills may also be impaired in people with WMH. Characterization of the abnormal areas of T2 signal as well as their appearance on other MR imaging sequences, when combined with clinical context and laboratory investigations, will often allow a unique diagnosis, or at least aid in narrowing the differential diagnosis.

Differential diagnosis of T2 hyperintense spinal cord lesions: Part A. Misdiagnosis of spinal subacute combined degeneration in a patient with elevated serum B12 concentration and sensory deficit level. Intramedullary cord hyperintensity at T2-weighted MRI is a common imaging feature of disease in the spinal cord, but it is nonspecific. The dipole-dipole interaction is also increased the strength of the local field which is dependent on the proximity of the adjacent dipoles. after an RF excitation pulse, there is relaxation of the spins from the transverse plane toward the main longitudinal magnetic vector (B 0) - this is T1 weighting. T2 reflects the length of time it takes for the MR signal to decay in the transverse plane. [2] They are also seen in a number of neurological disorders and psychiatric illnesses. 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.

Hello and hope you are doing well. With body tumors the contrast may be spectacular when the tumor T2 is increased and its D* is also decreased so that the contrast produced by both of these tissue properties is positive and synergistic.

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. Usually this is due to an increased water content of the tissue. Note: T2 relaxation is not to be confused with T2*, which is a broader phenomenon and includes static magnetic field effects in addition to the tissue-characteristic T2 relaxation. Careers.

Before [6], Postmortem studies combined with MRI suggest that hyperintensities are dilated perivascular spaces, or demyelination caused by reduced local blood flow. However, when T2 and D* are both decreased as with many prostate tumors, the T2 contrast is negative and the D* contrast is positive. Causes including simple MR artefacts, trauma, primary and secondary tumours, radiation myelitis and diastematomyelia were discussed in Part A.
