The x-gradient produces a magnetic field that varies linearly along the xaxis, the y-gradient produces a magnetic field that varies linearly along the y-direction, and the z-gradient produces a magnetic field that varies linearly along the z-direction. 36 3 Spatial Resolution in Magnetic Resonance Imaging To form images, magnetic gradients must be switched on and off rapidly. The time it takes for the gradient to reach its maximum strength is called the gradient rise-time. A major improvement in MR systems in recent years has been the production of magnetic gradients with higher maximum gradient strengths (up to 30– 50 milliTesla per meter, mT/m) and shorter rise times (down to 200 microseconds, µs).

Some MR systems also permit shimming on a patient-by-patient basis by the technologist to correct for non-uniformities due to the patient and the specialized receiver coils that are placed in the bore of the magnet. Separate circuits control the shim coils, and re-shimming the magnet by adjusting the current flowing in those coils can increase magnetic field uniformity across the sensitive volume of the anatomical region being imaged. 5 Tesla magnet will be uniform to within 1 part per million (ppm) over a 30 to 40 cm volume at the isocenter of the MR scanner.

9% recovered after 7T1. Tissues with more macromolecules of the correct size to enable these thermal interactions have shorter T1 values, indicating that the energy exchange between hydrogen nuclei and macromolecules occurs more rapidly. Tissues with very dilute concentrations of macromolecules, such as cerebrospinal and cystic fluids, have long T1-values, on the order of several seconds, because energy transfer occurs more slowly. 5 T). The reason that T1 is higher for most breast lesions, including cancers, than for normal fibroglandular tissues is that lesions tend to have higher water concentrations, and therefore fewer macromolecules per unit volume, than normal breast tissues.
