For a 1.5T MRI system the TR value should be set between 400-700ms to achieve a T1 weighted image. The image you just produced with an 800ms TR looks more like a proton density image than a T1 image. (You used a short TE). Which of the following would you do to correct the image produced to show the T1 properties of the tissue?
