Acoustic Radiation Force Impulse Imaging of Myocardial Performance

Solid appearance of pancreatic serous cystadenoma diagnosed as cystic at ultrasound acoustic radiation force impulse imaging.

CONTEXT Acoustic radiation force impulse imaging is an emerging imaging modality. The study of the pancreas is a new and promising application of ultrasound acoustic radiation force impulse imaging. CASE REPORT We present the first case of pancreatic serous cystadenoma which mimics a solid neoplasm at conventional imaging (US and CT), correctly diagnosed as cystic at ultrasound acoustic radia...

Passive hepatic congestion: Findings of two-dimensional, Doppler, and acoustic radiation force impulse imaging

Improving Displacement Signal-to-Noise Ratio for Low-Signal Radiation Force Elasticity Imaging Using Bayesian Techniques.

Radiation force-based elasticity imaging is currently being investigated as a possible diagnostic modality for a number of clinical tasks, including liver fibrosis staging and the characterization of cardiovascular tissue. In this study, we evaluate the relationship between peak displacement magnitude and image quality and propose using a Bayesian estimator to overcome the challenge of obtainin...

Ultrasound Diagnosis of Breast Cancer

Ultrasound is a popular imaging modality for its safety and low cost. Its role in the diagnosis of breast cancer is discussed, and its performance is then compared those of mammography (gold standard) and MRI. Besides conventional B-mode and color or power Doppler ultrasound images, latest development of acoustic radiation force impulse (ARFI) and supersonic shear imaging and their application ...

Acoustic radiation force impulse imaging of mechanical stiffness propagation in myocardial tissue.

Acoustic radiation force impulse (ARFI) imaging has been shown to be capable of imaging local myocardial stiffness changes throughout the cardiac cycle. Expanding on these results, the authors present experiments using cardiac ARFI imaging to visualize and quantify the propagation of mechanical stiffness during ventricular systole. In vivo ARFI images of the left ventricular free wall of two ex...
