| T1 and 12 are organized in a certain time interval acceptable physical properties change after a series of pulses, different organizations have different T1 and T2, it depends on the tissue reaction to the proton radio frequency pulse of applied magnetic field. By setting the MRI imaging parameters (TR and TE), TR is the repetition time interval i.e. RF pulse, TE is the echo time from the RF pulse is applied to the received signal to ask the time, TR and TE are the unitMilliseconds (ms), you can make the image (T1-weighted images or T2-weighted images were representative organizations Tl or T2 properties; by imaging parameter settings can also be made both Tl T2 characteristic properties of another image, called proton density-weighted images. |
