Acoustic Properties of Breast Fat [PDF]
Journal of Ultrasound in Medicine, 2015 ObjectivesThe American College of Radiology Breast Imaging Reporting and Data System (BI‐RADS) atlas for ultrasound (US) qualitatively describes the echogenicity and attenuation of a mass, where fat lobules serve as a standard for comparison. This study aimed to estimate acoustic properties of breast fat under clinical imaging conditions to determine ...

Acoustic properties of dialysed kidney by scanning acoustic microscopy [PDF]
Nephrology Dialysis Transplantation, 1997 A correlation between acquired renal cysts in the dialysed kidney and renal cancer has long been debated, but no changes in the physical properties of kidneys at the microscopic level have been reported. The purpose of the present study was to classify the physical properties of the kidneys of patients undergoing haemodialysis at several stages of ...
