T1= Fat- Appears Bright e.g. Grey matter = Water- Appears Dark e.g. CSF, water T2 Just opposite to T1
what is extensive motion artifact on the T2 sagittal sequence limiting interpretability?
T2 hyperintesities is a medical term used to describe high intensity areas viewed on an MRI image. In the elbow, it basically means that there is reduced blood flow to that area of the body.
T2 is a type of MRI imaging technique in which TE and TR (Echo time and Repetition time) are longer and the image's contrast and brightness is determined specifically by T2 signals. A "hyperintense lesion" would appear as a bright white spot on a T2-weighted MRI, and its location is in the left centrum semiovale. The centrum semiovale is a large region of "white matter". It is composed of the fibers carrying information to and from the surface of the brain (cortex) to the deeper structures of the brain and to the spinal cord.
LAeq is presser level measurement parameter. Full form of LAeq is " Equivalent continuous A-weighted sound pressure level". It is widely used around the world as an index for noise. LAeq = 10*log[1/(t2-t1) * Integration of (P2A/P20) between interval [t1 t2]] ;; where : LAeq = equivalent continuous A-weighted sound pressure level [dB] : p0 = reference pressure level = 20µPa : pA= A-weighted pressure [Pa] : t1 = start time for measurement [s] : t2 = end time for measurement [s]
T2 FLAIR is an MRI sequence used when scanning brain anatomy. It stands for Fluid Attenuated Inversion Recovery and is a T2 weighted scan where signal from CSF is nulled giving a good detailed view of brain anatomy.

A T2 weighted image, on a MRI, is not diagnostic, in and of itself. T2 hyperintensity could represent tumor, infarction, hemorrhage, or trauma, for instance. In the context of the clinical picture, the MRI is extremely helpful. If there has been no trauma, then the location and appearance of the T2 hyperintensity can point to a vascular cause versus a space-occupying lesion. The clinical course of the patient will cinch the diagnosis, when combined with the MRI findings - in cases such as these. In the case of a mass in the brainstem of a child, the most common cause would be that of a brainstem glioma. These account for anywhere between 10-20% of all brain tumors in children. However, this is not the only possibility (see above).
The type of MRI scan technique used to identify areas of an organ, such as the brain, which have recently been damaged or injured. Basic concepts involved are the use of a spin-echo sequence in T2-weight with two extra gradient echo pulses that are equal in magnitude and opposite in direction after excitation. DWI is increasingly important in the early detection and evaluation of many intracranial disease processes. JNFigueroa
Type your answer here... it is a T2 hyperintense foci
Hyperintensities refer to areas of high intensity on particular types of magnetic resonance imaging scans of the hum an brain. These small regions of high intensity are observed on T2 weighted MRI images within cerebral white matter or subcortical gray matter.
V1/T1 = V2/T2 Where temperature must be in Kelvins 67C + 273 = 340 K So 140/340 = 50/T2 Find T2 340/140(50) = T2 T2 = 121 K or -152C
