  1. CT ANGIOGRAPHYprepared by Dr khalid al joghaiman

  2. PATIENT PREP. • BUN 7-20 mg/dl • CREAT.- 0.6 –1.2 mg/dl • IODINE ALLERGY- STEROID THERAPY • HYPERVENTILATION BEFORE EXAM FOR BETTER BREATHOLD

  3. CONTRAST ADMINISTRATION

  4. ORAL CONTRAST???? WATER NEGATIVE CONTRAST

  5. AUTOMATED CONTRAST ADMINISTRATION SYSTEMS • SMARTPREP • CARE • SURESTART

  6. CONTRAST ADMINISTRATION AND SCANNING METHODS • BOLUS TRACKING • BOLUS TIMING • MANUAL PRESET TIME

  7. CARE BOLUS

  8. Bolus tracking- PE

  9. Tracking slice

  10. Bolus tracking- Carotids and Circle of Willis

  11. Circle of Willis?! 40 SEC

  12. CERBRAL CTA CAROTID CTA CHEST CTA (PE) 15 SEC 12 SEC 10-20 SEC MANUAL DELAYS

  13. CARDIAC CT

  14. TWO TECHNIQUES TO REDUCE MOTION ARTIFACTS IN CARDIAC CT • PROSPECTIVE TRIGGERING • RETROSPECTIVE GATING

  15. BOTH METHODS REQUIRE ECG MONITORING DIASTOLIC PHASE

  16. SCANNING DURING RR INTERVAL

  18. CALCIUM SCORING NO IV CONTRAST USED

  19. CALCIUM SCORING

  20. 3-D VISUALIZATION TOOLS IN CTA • MPR • MIP • SSD • VR • CINE

  21. CTA - MPR PLANE?

  22. MPR PLANE?

  23. MIP - CTA

  24. SSD -CTA

  25. VR - CTA

  26. CINE CTA

  27. SIMPLE FAST ANY PLANE VISUALIZATION LESS USEFUL IN COMPLEX VESSEL VISUALIZATION MPR
