T1= Fat- Appears Bright e.g. Grey matter
= Water- Appears Dark e.g. CSF, water
T2 Just opposite to T1

What does arachnoiditis on an mri mean?
Arachnoiditis is inflammation of the the leptomeninges (arachnoid and pia mater). These structures wrap the surface of the brain and spinal cord. When they are inflamed, whatever the underlying cause, gadolinium injection during an MRI scan causes enhancement of the leptomeninges on T1 weighted images. Many different health problems may cause arachnoiditis (from tuberculosis to carcinomatosis to autoimmune diseases). So, strictly speaking, arachnoiditis on an MRI means the leptomeninges enhance.
In MRI how do TR and T1 relate?
A long TR and short TE sequence is usually called Proton density -weightedA short TR and short TE sequence is usually called T1-weightedA long TR and long TE sequence is usually called T2-weighted
What does the medical abbreviation T1 mean?
T1 is a term used in describing MRI results to denote the signal that makes the more fatty areas bright.
Can an MRI differentiate between granulation tissue and fibrosis?
Usually it can because fibrosis will be dark on T1 and T2 weighted sequences (except in the liver). Granulation tissue is variable but not dark on both, and is vascularized, so it will enhace early after contrast administration. Fibrosis only enhances late after contrast administration.
What is a LAeq?
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]

What are the differences between a T1 and a T3 leased line?
T1 and T2 are two common types of lease lines in telecommunications. T1 is the standard and was developed by AT&T. T3 are often used for long-distance traffic and to build the core of a business network headquarters.
What is Balanced FFE in MRI?
Balanced FFE (Fast Field Echo) is the Philips name for the bSSFP Balanced Steady State Free Precession MRI pulse sequence. It is very fast (thanks to powerful gradients which recycle the magnetization) and gives high signal images (thanks to spin-echo-like refocusing of magnetization). The generic contrast it yields is T1/T2; that is, fluids and fat appear brighter than other tissue.
What is the difference between a T1 Line and a cable internet connection?
One of the biggest differences between T1 and cable is price. T1 is a lot more reliable and used mostly by business due to it's price. Cable is a bit more unreliable due to the bandwidth being shared by multiple users living in the area.
What does low t1 signal intensity mean?
I just had an MRI done and one of the comments was that an area of the scan showed a low signal intensity...as in, something is wrong with the tissue.
