MR spectroscopy has been shown to improve the specificity of lesion characterization both alone and when used in conjunction with dynamic contrast breast MR imaging . Breast cancers have been shown to have increased choline levels owing to increased cellularity and cell turnover; however, ductal carcinoma in situ (DCIS) and infiltrating breast cancers with a large DCIS component have shown to often be negative for elevated choline levels, somewhat limiting the sensitivity of this technique .
Resolution images, although this is a standard feature on most scanners. Partial readouts also affect the relative phase behavior of water and fat signals as discussed below. The second approach to reduce banding artifacts is to reduce the field inhomogeneity across the heart by using local shimming and second order shimming of the static field to minimize these artifacts by reducing the variations of the off-resonance phase across the selected region to less than 180 . Schar et al.  suggested higher order local shimming procedures to avoid banding artifacts.
This may also result in higher resolution. Conclusion The advantages and improvements of 3T imaging have made MR imaging increasingly attractive in comparison to diagnostic imaging with ionizing radiation and iodinated contrast agents for certain applications. Vascular imaging at 3T has improved the quality of MRA, diminished the needed contrast load, and has further diminished the need for digital subtraction angiography (DSA) or computed tomography (CT) angiography. While lesion detection in the abdomen and pelvis may shift toward MR imaging at 3T from CT, the improvements in MR imaging have been mostly a result of advances in RF coil design, gradient performance, and electronics to 24 improve readout and k-space reconstruction.
