The two stars have an angular separation of about 0. Orientation of the Probe Ultrasound transducers have a physical mark on them that provides orientation of the transducer’s placement on the patient relative to the projected ultrasound image on the viewing screen.

Gas in the left ventral colon may preclude identification of the left dorsal colon when it lies medial or dorsal to the left ventral colon.

Normal Abdominal Ultrasonography of the Horse

In this location, the only part of the stomach that normally can be seen is the wall of the greater curvature, which can be reliably identified as a curved line with proximity to the adjacent spleen and the gastrosplenic vein.

The size and location of the spleen is highly variable, though it should be identifiable immediately adjacent to the body wall, from the left ventral eight intercostal space to the paralumbar fossa. Hoffman K et al. Mitchell C et al. Create your page here. Couplant gel should be liberally applied. The liver can be located from the sixth to ecogeafia fourteenth intercostal spaces between the diaphragm and the right dorsal colon.

When the image is displayed on the viewing screen, most ultrasound machines display the position marker on the screen. Ideally, prior to ultrasonography, the patient’s hair should be clipped with a number 40 blade and the skin should be cleansed with isopropyl alcohol. Only a small portion of the right side of the liver can be imaged and estimates of size rely on its expanse across intercostal spaces.


Normal Abdominal Ultrasonography of the Horse

The renal cortex is more echogenic than the adjacent medulla, except in areas of the medulla where interlobar vessels course centrally to form the renal pyramids, which are most readily visible in the middle regions of the kidney, as compared to the poles.

Integration of Knowledge of Normal Abdominal Anatomy When scanning the equine abdomen it is helpful to use a systematic approach, scanning from top to bottom, rostral to caudal, left and right sides. In the city, it has the record of the oldest Brazilian ceramics outside the Amazon, dated years.

Many horses will tolerate transabdominal ultrasonography without sedation.

The interface between soft tissues and gas is an excellent example of this concept. The small intestine has the most visible motility of any part of the gastrointestinal tract, with peristaltic waves producing rhythms contractions.

The corticomedullary junction should be distinct, with the cortex approximately 1 cm thick. Metric prefixes The prefixes of the metric system precede a basic unit of measure to indicate a decadic multiple and fraction of a unit.

Portal veins have more connective tissue in their walls and thus have more echogenic walls than the hepatic veins. Freeman S et al. Participating teams The league had 12 teams participating in the —14 season, before expanding to 14 teams from the —15 season.

If clipping the hair is not an option, soaking the reproductvia with isopropyl alcohol will often suffice. This screen position marker is intended to orient the ultrasonographer to the displayed image.

Kirkberger R et al. The normal left ureter cannot be imaged.

Ecografía Del Tracto Reproductivo De Una Yegua

The left kidney can be found between the sixteenth to seventeenth intercostal space and the first to third lumbar vertebra, medial or deep to the spleen, between the level of the tuber coxae and the tuber ischii. The urinary bladdernongravid uterus, and ovaries are best imaged in the adult horse transrectally.


If however, sedation is needed, be mindful that alpha two agonists, such as xylazine and detomidine, will induce a transient state of ileus, and thus intestinal motility may be reduced and the luminal diameter of the small intestine may appear more dilated than in a patient that is not sedated. The small intestine is hard to visualize in normal horses unless a peristaltic wave generates transient expansion of the lumen from movement of fluid contents.

Unit prefix A reeproductiva prefix is a specifier or mnemonic that is prepended to units of measurement to indicate multiples or fractions of the units. The prefixes of the metric system precede a basic unit of measure to indicate a decadic multiple and fraction of a unit. The right kidney architecture is similar to that yegguas for the left kidney. It is also easy to fool yourself into repriductiva that a lesion is enormous, only to realize that the depth of view is only a few centimeters and therefore magnified.

The prefixes of the metric systemsuch as kilo and millirepresent multiplication by powers of ten. The left ventral colon is sacculated. When the image is displayed on the viewing screen, most ultrasound machines display the position marker on the screen.

Historically, many prefixes have been used or proposed by various sources, but only a narrow set has been recognised by standards organisations. Wall thickness is less than 4 mm and gas in the lumen precludes imaging the contents and far wall.
