Significance of low level echoes within the gallbladder

AJR. American Journal of Roentgenology

Thick bile may appear as a nonshadowing, dependent, echogenic layer within the gallbladder. In vivo sonographic imaging of the canine gallbladder showed that highly viscous, desiccated bile appeared echogenic and could potentially prevent imaging an enlarged gallbladder or dilated bile ducts. Selected clinical cases demonstrated that multiple nonshadowing calculi, pus, cholesterol crystals, and possibly abnormal mucous in the gallbladder may be sonographically indistinguishable from thick bile.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.

The Tendon Seed Network

Tendons are rich in the extracellular matrix and are abundant throughout the body providing essential roles including structure and mobility. The transcriptome of tendons is being compiled to understand the micro-anatomical functioning of tendons. Discover the latest research pertaining to the Tendon Seed Network here.
