This presentation was held by dr. Antonio Pio Masciotra in 2011 at Pavia's Elastography Meeting in the round table

4. THE HISTORY OF SONO-ELASTOGRAPHY

5. Strain Shear wave

6. STRAIN with different
compressions
Inhomogeneous elasticity Uniform low elasticity

7. SHEAR WAVE
Normal gland 8.29 kPa Normal gland 1.66 m/sec
Nodule 8.46 kPa Nodule 1.68 m/sec

9. Strain Shear wave

10. Soft or Hard ?
STRAIN SHEAR WAVE
Mainly ‘soft’ thyroid nodule Mainly ‘hard’ thyroid nodule

11. Hard or Soft?
Shear wave Shear wave
kPa 65.87 3.69 m/sec

12. Are our measurements really indicative of
tissue elasticity values?
QA sono-elasticitography

13. 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

15. Different reference values in quantification
and staging of hepatic fibrosis

16. Aims of elastography
Correct tissue elasticity quantification
Identification of ‘cut off’ elasticity values
for correct diagnosis of diffuse and
focal diseases

17. SO WE NEED TO HAVE
STANDARDS BOTH IN
TECHNIQUES OF
ACQUISITION AND IN THE
MEASUREMENTS
