Gadolinium molecules shorten the spin-lattice relaxation time (T1) of voxels in which they are present. As a result, on T1-weighted images they have a brighter signal. WebHigh magnetic field ( B0) is one such option, representing the ultimate limit of the SNR of images. The SNR is directly proportional to B0 and is the primary determinant of the image resolution. 15,16 HF MRI is also critically dependent on RF coil technology and gradient design. Particularly, RF plays an important role in the quality of HF images. diamond cut knives review
