|Official Title:||Ultrasound Based Acoustic Radiation Force Impulse, Shear Wave Velocity Imaging in Pediatric Patients Undergoing Liver Biopsy|
- ARFI/VTQ and ARFI/VTIQ Liver Shear Wave Speed vs. Liver Histologic Fibrosis Score [ Time Frame: 10 minutes ]
Tissue shear wave speed is positively correlated to a material's/tissue's stiffness and can be noninvasively measured by ultrasound. The relationship between liver shear wave speed and liver histologic fibrosis score were assessed using 2 different ultrasound methods. Liver shear wave speed as obtained using 2 different ultrasound methods served as our primary outcome measures.
Note, the histologic scoring system (Ishak) ranged from 0 to 6, where 0 = no fibrosis and 6 = cirrhosis.

Experimental: Ultrasound-based Acoustic Radiation Force Imaging
The liver was scanned using ultrasound and ultrasound-based acoustic radiation force impulse imaging technique (ARFI).
Device: Ultrasound-Based Acoustic Radiation Force Impulse (ARFI)
Research scans using ultrasound-based acoustic radiation force impulse (ARFI) will image the liver non-invasively.
