  This T1 time, along with the T2 time, a similar measurement but in this case the energy transfer between neighboring spins, provide a more unique signature to a particular MRI signal, allowing for more accurate imaging in the body. One can compare the different T1 and T2 times and tell more accurately where in the body the signal is coming from.

  Other methods of sampling the MRI signal produce different gray scales. Looking at a T1 and T2 weighted brain scan side by side, it might appear as though the gray scale had been inverted on the T2. The gray densities of the T1 brain tissue would be dark or black on the T2, and the black CSF of the T1 would be white on the T2.

• A Basic Overview of the Imaging Modalities Covered in BIO 335

  The intensity of signal and thus image contrast can be modulated by altering certain parameters, such as interval between Rf pulses (TR) and time between Rf pulse and signal reception (TE). So-called T1-weighted (T1W) images are produced by keeping TR and TE relatively short.

  Colloid cyst can show any signal in T1 [hypo or hyperintense] and any signal in T2 [hypo or hyperintense] with no contrast enhancement. Sometimes marginal enhancement is seen in the cyst which shows low signal in T1 WIs. ( Most of the …

• What Does Hyperintensity Mean On An Mri Report? | HealthCentral

  How signal depends on T1 (eqns 4,5) A gradient echo sequence is usually used, for speed. Flip angle (B1) errors, including slice profile effects, limit the accuracy of this. The ‘native T1’, i.e. the T1 of the tissue before injection of Gd, must be known in order to calculate signal enhancement.
