Sono elastography meeting pavia 2011 may 29-30 - presentation of dr. masciotra

  1. 1. Thyroid round tableDr. Antonio Pio Masciotra Campobasso
  2. 2. THE HISTORY OF SONO-ELASTOGRAPHY
  3. 3. Strain Shear wave
  4. 4. STRAIN with different compressionsInhomogeneous elasticity Uniform low elasticity
  5. 5. SHEAR WAVENormal gland 8.29 kPa Normal gland 1.66 m/secNodule 8.46 kPa Nodule 1.68 m/sec
  6. 6. Strain Shear wave
  7. 7. Soft or Hard ? STRAIN SHEAR WAVEMainly ‘soft’ thyroid nodule Mainly ‘hard’ thyroid nodule
  8. 8. Hard or Soft?Shear wave Shear wave kPa 65.87 3.69 m/sec
  9. 9. Are our measurements really indicative of tissue elasticity values?QA sono-elasticitography phantom
  10. 10. We need to have standards of unity measures BACKGROUND ELASTICITY• Material : Zerdine® • Background: 25 kPa• Speed of sound : 1545 m/s 10 m/s • Lesion Type I: 08 kPa• Attenuation Coefficient : 0.50 dB/cm-MHz • Lesion Type II: 14 kPa • Lesion Type III: 45 kPa LESIONI • Lesion Type IV: 80 kPa• Material : Zerdine®• Attenuation Coefficient : 0.50 dB/cm-MHz
  11. 11. Different reference values in quantification and staging of hepatic fibrosis
  12. 12. Aims of elastographyCorrect tissue elasticity quantificationIdentification of ‘cut off’ elasticity values for correct diagnosis of diffuse and focal diseases
  13. 13. SO WE NEED TO HAVE STANDARDS BOTH IN TECHNIQUES OFACQUISITION AND IN THE MEASUREMENTS
  14. 14. Thanks to my Technicians Mr. Nicolino Spina and Mrs. Carmela Leccese By Dr. Antonio Pio Masciotra Campobasso-Molise- Italy To ZAPRAD
