Advances in diagnostic ultrasonography.

This research article focuses on the various types of ultrasonographic equipment available for equine veterinary practice, their features, advantages, limitations, and suitable applications.

Assortment of Ultrasonographic Equipment

• The article begins by acknowledging the diverse range of ultrasonographic equipment that can be used in equine veterinary practice. However, it points out the fact that no single machine is ideal for all imaging types.
• Image quality is underlined as the fundamental factor in choosing equipment, but it must align with the specific needs of the practitioner.

Essential Factors in Equipment Selection

• Several points crucial to equipment selection are identified. These factors include available transducer frequencies, transducer footprints, displayed depth of field, frame rate, gray scale, the presence of simultaneous electrocardiography, Doppler, and image modifying functions.
• Additionally, the ability to make measurements from video playback and the potential for future upgrades to the equipment are also deemed notable considerations.

Role of Linear Array and Sector Technology

• The study highlights that linear array and sector technology form the basis of modern equine ultrasonography.
• Linear array technology is deemed highly useful for practices dealing with a large volume of broodmares, whereas sector technology is more suited to a general equine practice.

Utility of Convex Linear Scanner

• The convex or curved linear scanner, equipped with a linear array rectal probe, provides more versatility in practical application than the standard linear array. This device finds more varied use in ultrasonographic evaluations.

Annular Array and Phased Array Systems

• The article mentions improved image quality provided by the annular array and phased array systems. However, it recognises that each system has its own limitations.

Affordability and Versatility of Sector Scanners

• The paper ends by affirming that the newer sector scanners continue to provide the most versatile and affordable options for a general equine practice.
