Careers. You have 4 two lateral venticles, and two midline. 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. Magnetic resonance imaging. 2015 Dec;53(12):842-8. doi: 10.1038/sc.2015.110. One that immediately comes to mind (suggested by my colleague Graeme Bydder) is the Pulsed The result is that the Mxy component of the magnetic vector decreases exponentially as a function of the T2 time constant (Figure 1). Radiologists play a valuable role in helping narrow the differential diagnosis by integrating patient history and laboratory test results with key imaging characteristics.

RE: differential diagnosis of T2 hyperintense spinal cord lesions. Certain features of gait pattern associated with WMH are: slight widening of the base, slowing and shortening of stride length and turning en bloc. Examples of T1 and T2 in biological tissues include:CSF, T1=1.9 seconds and T2=0.25 seconds; brain white matter, T1=0.5 seconds and T2=0.07 seconds (70 msec). T2 reflects the length of time it takes for the MR signal to decay in the transverse plane. It is a measure of the time taken for spinning protons to lose phase coherence among the nuclei spinning perpendicular to the main field. These foci were not related to cognitive function or cerebrovascular risk factors; instead, they were highly correlated to age, being present in 11 of 11 subjects aged 75 years and over. ?

A: When making the diagnosis of MS, brain and cervical spinal cord MRIs should be obtained in all cases unless specific contraindications. The T2 tells you that the image was made using a T2-weighted MRI scan. 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.
