Transcript

  • 1. Neonatal transcranial ultrasound...The normal ,and abnormal . Dr/Ahmed Bahnassy Consultant Radiologist PSMMC
  • 2. Technical considerations 1.choosing the probe. 2.adjusting depth and focus. 3.adjusting gain. 4.right and left labelling. 5.planes consideration. 6.use of previous scans for moving heads
  • 3. Planes and landmarks coronal sagittal
  • 4. Coronal scan 1
  • 5. Coronal scan 2
  • 6. Coronal scan 3
  • 7. Coronal scan 4
  • 8. Coronal 5
  • 9. Importance of standardizing scans Brain diagram showing a coronal view as seen in ultrasound by greater fontanel. this explain some usefull measurements for ultrasound in neonatal brain: 1- Lateral ventricle (posterior horn): normal ≤ 13mm 2 - Third ventricle: normal ≤ 10mm 3 - Interhemispheric fissure: normal ≤ 6mm 4 - Subarachnoid space ≤ 4mm
  • 10. Midline sagittal
  • 11. Para-sagittal 1
  • 12. Para-sagittal 2
  • 13. Para-sagittal 3
  • 14. Other imaging planes
  • 15. Germinal matrix Highly vascular structure that gives rise to nerve cells. Just above the caudothalamic groove and beneath ependymal lining of ventricles. Begins to involute at 3rd month of gestation and complete by 36 week. Source of bleeding in premature infants.
  • 16. Germinal matrix haemorhage(acute)
  • 17. Resolving haemorhage
  • 18. Grades II and III
  • 19. Grade IV
  • 20. Periventricular echogenicity According to van Wezel et al. • Grade 0: normal echogenicity of the periventricular white matter ( less than that of the choroid plexus) • Grade 1: moderately increased echogenicity of the periventricular white matter, the affected region being almost as bright or as bright as the choroid plexus . Grade 2: seriously increased echogenicity, the affected region being obviously brighter than the choroid plexus .... • Separate notation: homogeneous, nonhomogeneous .
  • 21. Periventricular leukomalacia
  • 22. Subarachnoid and subdural collections
  • 23. Ischaemic injury • Hyperechogenic areas in thalamus .caudate nucleus...watershed areas. Low RI Compensatory mechanism.
  • 24. Abnormal (cyst )!!
  • 25. Using doppler
  • 26. Posterior fossa abnormality Arnold Chiari malformation Dandy walker complex
  • 27. Missing structure 1 normal
  • 28. Missing structure 2 normal
  • 29. Missing structure 3 normal
  • 30. abnormal (canal )
  • 31. abnormal echogenic shadows.
  • 32. Structure too large
