They allow precise definition and localization of the tissue parts to be examined. The three commonly used types in diagnostics are:
  • Spin-Echo Sequence
  • Gradient-Echo Sequence
  • Inversion Recovery Sequence
The selection of pulse sequences is determined by:
  • The inhomogeneity of the magnetic field
  • The material to be examined (tissue), including the magnetization properties of the sample
  • The chemical environment of the sample
One „limitation“ arising from these properties is the significant drop in signal strength during multiple measurements, which can lead to unclear differentiation and contrast of different tissues. To address this, various measurements with different pulse sequences can be employed: (a) Measurements with short repetition time (TR) compared to relaxation T1; with long repetition time (TR), or with a repetition time comparable to TR. Pulse Sequence Comparisons: (a) Spin-Echo Sequence – Comparable repetition time: TR>T1 (b) Gradient-Echo Sequence – Short repetition time: TR<T1 (c) Inversion Recovery Sequence – Long repetition time: TR>T1   To deepen your knowledge of the quantum physical processes in MRI, you can explore additional resources through book recommendations available on Amazon by clicking the next button: Book Recommendation on Amazon: Spin, Quantum Physics  Book Recommendation on Amazon: Nuclear Magnetic Resonance Imaging – MRI   Or, if you just want to browse a bit more on AliExpress or Amazon, click the following button: To browse on AliExpress: Laptop discounted by 50% To browse on AliExpress: Watch discounted by 87% To browse on Amazon: NIKE shoes
