The contrast of these images is mainly determined by spatial variations in the spin density (1H) of the imaged specimen. - In spin-echo sequences this contrast is achieved at short repetition and long - echo times. - In a gradient-echo acquisition, PD weighting dominates the contrast at long - repetition and short echo times, and at small flip angles. + This contrast is achieved at short echo times and long repetition times; + for gradient echo, this weighting is also possible with a short TR (TR<
