Almost immediately, they lose coherence as some spin slightly faster than the others. prolonged illness. Typical examples are shown in Figures 1-8. The poor blood supply and vascularity of tendons mean that is can take a long time for them to heal on there own. prolongation definition: 1. the act of making something last a longer time: 2. the act of making something last a longer. So substances with short T2's have smaller signals and appear darker than substances with longer T2 values. Pathological tissue usually has more water than normal brain so this is a good type to scan to pick this up. The contrast that goes into your vein for the MRI seeps out of leaky blood vessels in the brain where there is active inflammation. a focus of T2 hyperINTENSITY means that the signal from that area has different tissue characteristics compared to normal brian tissue. White matter disease is an umbrella term for damage to your brain's white matter caused by reduced blood flow to the tissue. What are some examples of how providers can receive incentives? This slower motion is closer to the Larmor frequency.

[9] Severe WMH is consistently shown to be associated with gait disorders, impaired balance and cognitive disturbances. There is also mild susceptibility differences between bone and soft tissue that could contribute to a dark appearance at interfaces, as between marrow and bone trabecula. T2-hyperintense foci on brain MR imaging MRI is a sensitive method of CNS focal lesions detection but is less specific as far as their differentiation is concerned. Certainly, these findings are not diagnostic for any entity, and may represent old head injury, prior cigarette smoking, or even changes in arteries a to start having migraine at 41. Generally, the lesions remain bright for only 1-2 months. An abnormal prolongation can be associated with metabolic problem. To understand this "paradox", you must realize that apixel's "brightness" or "darkness" on an MR image is directly related to the magnitude of the detected MR signal.
