In the field of ultrasonic diagnosis, its attenuation property in the brain has been also explored. Investigated are the ultrasonic attenuation of the brain following experimental head injury as well as cerebral circulation and water content of brain, the purpose of which are to analyse the essential mechanism of ultrasonic attenuation as its relationship to the brain edema. I studied the conti...

The use of combined isotope and ultrasonic scanning in the diagnosis of amoebic liver abscess is described, together with details of three cases of this condition seen in the Bristol area in a period of two years. The addition of ultrasonic scanning greatly increases the accuracy of diagnosis by demonstrating a fluid-filled, space-occupying lesion and should ideally be employed whenever liver a...

Hepatic vein stenosis after liver transplantation is a relatively rare complication that could even result in graft loss. However, it is difficult to arrive at a definite diagnosis at the early stage of postoperation, and there are few researches on ultrasonic shear wave elastography in the diagnosis of hepatic vein stenosis. We report the case of an 11-year-old male patient with cirrhosis due ...

To achieve a precise noninvasive temperature estimation, inside patient tissues, would open promising research fields, because its clinic results would provide early-diagnosis tools. In fact, detecting changes of thermal origin in ultrasonic echo spectra could be useful as an early complementary indicator of infections, inflammations, or cancer. But the effective clinic applications to diagnosi...

The aim of this study was to evaluate ultrasonic P-wave velocity as a feature for predicting some physical and mechanical properties that describe the behavior of local building limestone. To this end, both ultrasonic testing and compressive tests were carried out on several limestone specimens and statistical correlation between ultrasonic velocity and density, compressive strength, and modulu...

The Cavitron ultrasonic surgical aspirator causes localised ultrasonic tissue fragmentation and has recently been used to remove intracranial tumours. We have examined tissue fragments from 17 operations in which the apparatus was used: in all cases a definitive diagnosis could be made from the material aspirated. This finding has not been previously described.
