Are T2 and Flair signal hyperintensities associated with the white matter in the brain?
yes
A sample of air has a volume of 140ml at 67degrees Celsius At what temperature will its volume be 50ml at constant pressure?
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
Multiple T2 hyperintense white matter lesions?
Multiple areas of T2 spots were seen in the white matter on both sides
What is the bacterium attacked by T2 phages?
Bacteriophage

What is T2 signal in MRI?
The T2 signal is used by MRI machines to help identify different characteristics of tissues within the brain. For example, the T2 signal can help identify if the tissue contains too much water.
Brain T2 signal abnormal?
What does it mean when the MRI states Marked patchy to confluent abnormal T2 signal white matter? increase brain T2 signal from white matter in MRI might be due to AIDS dementia complex
Are T2 and Flair signal hyperintensities associated with the white matter in the brain?
yes
What is T2FLAIR?
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.
What is a t2 signal in the left paraspinous muscle?
There are a multitude of electrical signal released by neurons to activate a response in a muscle. A t2 signal in the left paraspinous muscle refers to the impulse from the t2 vertebrae to the muscle on the left of the spine .
What does it mean the brain parenchyma shows periventricular T2 hyperintensity and a few scattered subcortical foci of increased T2 and flair signal intensity in the frontal lobes that are nonspecifi?
what does this mean? Impression: There are scattered foci of T2/FLAIR hyperintensity within the periventricular, deep and subcortical white matter. The findings are nonspecific but may be seen in mild to moderate small vessel ischemic changes. No evidence for acute infarct or hemorrhage.
What is a Hyperintense T2 signal mass in the region of the head of the pancreas?
what is hyper intense t2 lesion in the right liver lobe
Why is T2 matter white in the brain?
T2 is seen as a foci of white spots on MRIs of the brain. They are associated with a number of disorders: normal aging, MS, etc.
What is T2 hyperintense lesion at left centrum semiovale?
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.
What does it mean when there are multiple abnormal foci of high T2 signal scattered along the subcortical and periventricular region?
Your physician should explain you the protocol, but I can try to help a bit though i'd need more details. This is the protocol of a Magnetic Resonance scan (MRI, MRT, KST,... it has many names), i assume of your brain. They see multiple nodes that give a high signal on T2 images. Basically, they see nodes, and the fact that they light up on T2 tells you something about their contents. On T2 images, what lights up has a density about the same as water. About the subcortical and periventricular: this is just the region, subcortical = under the cortex. The cortex is the outer rim of your brain. Periventricular = around the ventricle, a ventricle is a chamber of cerebrospinal fluid in your brain. All things together, my guess (can only guess as i don't have more details and can't see the images), is that these are cysts.
What is Modic 2 degenerative endplate changes?
Modic changes, a common observation in MR imaging, are signal intensity changes in vertebral body marrow, adjacent to the endplates of degenerative discs.Michael T. Modic, MD, professor of radiology and neurology at Case Western in Cleveland, wrote about these changes in the journal Radiology in 1988, and his name has been associated with these changes ever since.Modic changes take 3 main forms:Type I· Decreased signal on T1, and increased signal on T2.· Represents marrow edema.· Associated with an acute process.· Histological examination shows disruption and fissuring of the endplate and vascularized fibrous tissues within the adjacent marrowType II - the most common type· Increased signal on T1, and isointense or slightly hyperintense signal on T2.· Represents fatty degeneration of subchondral marrow.· Associated with a chronic process.· Histological examination shows endplate disruption with yellow marrow replacement in the adjacent vertebral body.Type I changes convert to Type II changes with time, while Type II changes seem to remain stable.Type III· Decreased signal on both T1 and T2.· Correlate with extensive bony sclerosis on plain radiographs.· Histological examination shows dense woven bone; hence, no marrow to produce MRI signal.MODIC CHANGES on MRIT1T2SignificanceTYPE 1¯­EdemaTYPE II­® (or slight­)Fatty DegenerationTYPE III¯¯Bony Sclerosis
