Ultrasound measurements and normal findings in the thyroid gland.

The present work describes the process of the sonographic examination, normal findings and measurements in the B-mode ultrasound evaluation. Reference is made to anatomical variants in shape, the pyramidal lobe, tubercle of Zuckerkandl, ectopic thyroid tissue, and their significance. Particular attention is paid to the reference values, the very miscellaneous reference values in different geographic regions of the world and influencing factors.

Revision of trapeziometacarpal arthroplasty.

Complications of trapeziometacarpal arthroplasty are uncommon, but are classified as intra- and post-operative, dislocation and loosening being the main causes of revision surgery. Periprosthetic fracture and ossification are rare. Whenever possible, prosthetic revision techniques consist in partial or total replacement with modular implants.

WFUMB Commentary Paper on Artificial intelligence in Medical Ultrasound Imaging.

Artificial intelligence (AI) is defined as the theory and development of computer systems able to perform tasks normally associated with human intelligence. At present, AI has been widely used in a variety of ultrasound tasks, including in point-of-care ultrasound, echocardiography, and various diseases of different organs. However, the characteristics of ultrasound, compared to other imaging modalities, such as computed tomography (CT) and magnetic resonance imaging (MRI), poses significant additional challenges to AI.
