A case of adult intussusception with greyscale, contrast-enhanced ultrasound and computerised tomography correlation

Contrast-enhanced lesions on computerised tomography in multiple sclerosis.

Two patients are described in whom computerised tomography revealed contrast-enhanced lesions in the early stages of multiple sclerosis. Such lesions may be differentiated from tumours by their transient nature, lack of space-occupying effect, and localisation in the white matter. Contrast enhancement in demyelinating disease is probably related to local breakdown of the blood-brain barrier.

Cumulative phase delay imaging for contrast-enhanced ultrasound tomography.

Standard dynamic-contrast enhanced ultrasound (DCE-US) imaging detects and estimates ultrasound-contrast-agent (UCA) concentration based on the amplitude of the nonlinear (harmonic) components generated during ultrasound (US) propagation through UCAs. However, harmonic components generation is not specific to UCAs, as it also occurs for US propagating through tissue. Moreover, nonlinear artifac...

Adult intussusception: A case series and review

AIM To identify factors differentiating pathologic adult intussusception (AI) from benign causes and the need for an operative intervention. Current evidence available from the literature is discussed. METHODS This is a case series of eleven patients over the age of 18 and a surgical consultation for "Intussusception" at a single veteran's hospital over a five-year period (2011-2016). AI was ...
