This study will evaluate the effectiveness of Acoustic Radiation Force Impulse (ARFI)- Imaging compared to Transient Elastography (FibroScan) in differentiating liver fibrosis in patients with chronic hepatitis C. Patients who are scheduled to have a liver biopsy will also undergo ARFI and FibroScan testing. The liver biopsy will be used as the reference method. The target sample size is 433.
Primary Purpose: Diagnostic

This is a study that will evaluate the utility of measuring liver and spleen stiffness before and after a meal by a non invasive ultrasound based technologies called Fibroscan (Transient e...
Liver stiffness measurement (LSM) by non invasive methods is increasingly used to estimate liver fibrosis in patients with chronic liver diseases. However, there is growing evidence that f...
The goal of this study is to determine if ultrasound tools can be used to detect liver stiffness. Acoustic radiation force impulse (ARFI) elastography and backscatter will be used to see i...
A prospective, pilot study using acoustic radiation force imaging (ARFI) ultrasound (US) to quantify liver stiffness in children and young adults with chronic liver disease. ARFI results w...
The aim of this study: 1. To evaluate the correlation between the clinic tools and ultrasound elastography/ ARFI imaging in stroke patients. 2. To assess the reliability of elastography/ A...
Purpose To investigate the clinical utility and longitudinal change of acoustic radiation force impulse (ARFI) ultrasonographic (US) imaging in patients with chronic hepatitis B. Materials and Methods...
The aim of the present study was to quantify the stiffness of the median nerve (MN) at the carpal tunnel inlet by acoustic radiation force impulse (ARFI) elastography and to evaluate whether ARFI can ...
The purpose of this study was to evaluate the application of a new elastographic technique, acoustic radiation force impulse (ARFI) imaging, and its diagnostic performance for characterizing breast le...
To compare on-treatment and off-treatment parameters acquired using acoustic radiation force impulse elastography, the Fibrosis-4 (FIB-4) index, and aspartate aminotransferase-to-platelet ratio index ...
Non-invasive imaging methods based on the mechanical response of an object to a vibrational or impulsive force. It is used for determining the viscoelastic properties of tissue, and thereby differentiating soft from hard inclusions in tissue such as microcalcifications, and some cancer lesions. Most techniques use ultrasound to create the images - eliciting the response with an ultrasonic radiation force and/or recording displacements of the tissue by Doppler ultrasonography.
The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.
The use of pre-treatment imaging modalities to position the patient, delineate the target, and align the beam of radiation to achieve optimal accuracy and reduce radiation damage to surrounding non-target tissues.
A condition caused by dysfunctions related to the SINOATRIAL NODE including impulse generation (CARDIAC SINUS ARREST) and impulse conduction (SINOATRIAL EXIT BLOCK). It is characterized by persistent BRADYCARDIA, chronic ATRIAL FIBRILLATION, and failure to resume sinus rhythm following CARDIOVERSION. This syndrome can be congenital or acquired, particularly after surgical correction for heart defects.
Timing the acquisition of imaging data to specific points in the breathing cycle to minimize image blurring and other motion artifacts. The images are used diagnostically and also interventionally to coordinate radiation treatment beam on/off cycles to protect healthy tissues when they move into the beam field during different times in the breathing cycle.
Hepatology is the study of liver, gallbladder, biliary tree, and pancreas, and diseases associated with them. This includes viral hepatitis, alcohol damage, cirrhosis and cancer. As modern lifestyles change, with alcoholism and cancer becoming more promi...
