Presentation Transcript

  1. Lecture 2 Overview & comparison of different imaging modalities Advanced Biomedical Imaging Dr. Azza Helal A. Prof. of Medical PhysicsFaculty of MedicineAlexandria University

  2. Comparison of different imaging modalities • Projection views • Ionizing radiation • Speed • Contrast resolution

  3. Projection views • Limited visualization Plain x ray & Isotope scan • Flexible imaging planes Cross-section views CT & MRI

  4. Flexible imaging planes with MRI.

  5. MRI angiography

  6. Ionizing radiation • Plain x - ray, CT & isotope scan

  7. 3. Speed US Fast Plain x ray CT MRI Isotope scan Slow

  8. 4. Contrast

  9. Contrast resolution Plain x ray & CT reflect bone contrast MRI reflects soft tissue contrast

  10. Assignments One student will be selected for assignment

  11. Suggested Readings David Sutton’s Radiology Physics for medical imaging by RF Fare & PJ Allisy-Roberts.

  12. Questions Mention the advantages of MRI over CT? Enumerate the imaging modalities that use ionising radiation?

  13. Thank you
