An obvious difference, however, is that the inner and outer tables of the skull are black on the MRI scan, while compact bone on the CT scan is white. It would be a mistake to consider MRI as just the next generation CT scanner (Figure: see frontispiece).troponins 发表于 2025-3-27 08:46:41
Ullrich Pietsch,Václav Holý,Tilo Baumbachxity is both bewildering and a source of hope and challenge. To exploit the magnetic properties of tissues for clinical imaging, MRI scanners, which are probably an order of magnitude more complicated than CT scanners, have been built. However, the complexity of the magnetic properties of tissues ofTrigger-Point 发表于 2025-3-27 12:40:40

Tissue Characterization: T1 and T2,might not be worth the major effort already undertaken to develop clinical scanners. The great potential of MRI derives from its ability to provide several means of characterizing normal and pathological tissues.在驾驶 发表于 2025-3-28 09:47:59
Tissue Characterization and Pulse Sequencing,those of a more familiar object — a compass needle. This comparison was valid because a compass needle and a hydrogen nucleus share several properties: In the presence of a magnetic field, they both tend to align with the external field, absorb energy through the phenomenon of resonance, and subseqularder 发表于 2025-3-28 12:13:42
