A mri was taken and the impression says abnormal t2 prolongation identified in the periventricular white matter region, what does this mean? What does "increased T2 prolongation involving the right midbrain" mean on his MRI? T2 (transverse relaxation time) is the time constant which determines the rate at which excited protons reach equilibrium or go out of phase with each other. The water that is in bone, teeth, and calculi would mostly be bound as to collagen and would have a very short T2 time constant and appear dark. [5] Hyperintensities appear as "bright signals" (bright areas) on an MRI image and the term "bright signal" is occasionally used as a synonym for a hyperintensity. Curr Probl Diagn Radiol.

In people with Alzheimer's, higher WMH are associated with higher amyloid beta deposits, possibly associated with small vessel disease and reduced amyloid beta clearance.[11]. WMH's are also referred to as Leukoaraiosis and are often found in CT or MRI's of older patients. CCF-Neuro-M.D.-PW. 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. Supraspinatus Muscle and Rotator Cuff Tendonitis Treatment. [7], White matter hyperintensities can be caused by a variety of factors including ischemia, micro-hemorrhages, gliosis, damage to small blood vessel walls, breaches of the barrier between the cerebrospinal fluid and the brain, or loss and deformation of the myelin sheath. 2000 Nov;10(4):689-704 ,viii.

FInstP PJAOBEPFIPSM, CSci JWMFIPEM. 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 (Mxy). Hello and hope you are doing well. Without going into the physics of MRI (which I doubt even the most ardent Radiologist could explain), prolongation of the T2 signal (a bright area on , MS, normal and other. However, when T2 and D* are both decreased as with many prostate tumors, the T2 contrast is negative and the D* contrast is positive. A wide range of instructive cases is discussed here, with review of the published reports focusing on pertinent MR features to aid in diagnosis. They are all conncected. Resting the shoulder and upper arm is necessary at the first sign of pain from an injury. How do you treat inflammation of the supraspinatus tendon?

My doctor wants me to have blood drawn, a urinalysis and an ultrasound. 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. The poor blood supply and vascularity of tendons mean that is can take a long time for them to heal on there own.
