“…2 Although intraoperative B-mode ultrasonography was used as early as 1983 to locate, as well as to guide the ligation of, an intrahepatic portocaval shunt in a dog, 30 portography has traditionally been used for intraoperative imaging of the shunt and the portal vasculature, and intraoperative abdominal ultrasonography has remained uncommon in veterinary medicine. 33 However, intraoperative ultrasonography offers several advantages over portography. When image intensifiers are used in the operating suite for mesenteric portography, the staff must wear lead aprons during the whole time of the surgery to protect themselves against radiation.…”

A method for intraoperative measurement of portal blood flow velocity with duplex Doppler ultrasonography in 7 dogs with congenital intrahepatic portosystemic shunts is described. The aims of the study were to determine whether intraoperative ultrasonography was an acceptable alternative to mesenteric portography in such dogs and to identify quantitative portal hemodynamic variables that might correlate with clinical outcome better than portal pressure does. Ultrasonographic measurements did not influence decision-making by the surgeon, who attenuated the shunt on the basis of appearance of the viscera and change in mean systemic arterial blood pressure. All dogs recovered without complications, and surgery was considered to be successful in all 7. Intraoperative B-mode ultrasonography provided real-time information about the anatomy of the shunt and the portal branches, suggesting that it may be a useful alternative to mesenteric portography. The time-averaged mean portal blood velocity ranged from 6.5 to 33.7 cm/s before shunt attenuation and from 5.0 to 9.5 cm/s after shunt attenuation. This narrow range of postligation velocities suggested that intraoperative ultrasonography might be an alternative to intraoperative portal pressure measurement.

“…In certain human tumours, the diagnostic accuracy of ultrasound‐guided fine‐needle aspiration can reach up to 92% while inflammatory and infectious lesions have a lower percentage of accurate diagnosis (Catalano et al ., 2002). In veterinary medicine, aspiration is generally favoured over biopsy in certain circumstances such as small lesions (<1 cm diameter) or lesions of the spleen where the potential for haemorrhage is high (Nyland, 1995; Penninck & Finn‐Bodner, 1998). Ultrasound‐guided aspiration is often attempted prior to tissue core biopsy if neoplasia is a primary differential diagnosis or if the risk of morbidity of core biopsy is deemed too high.…”

“…Ultrasound‐guided tissue core biopsy is performed under heavy sedation or anaesthesia using Tru‐cut or automated biopsy devices (Penninck & Finn‐Bodner, 1998). Tissue core biopsies are typically acquired using 14–18 gauge needles.…”

With the recent advances in diagnostic imaging technology, cancer imaging in veterinary medicine has become more specific for disease diagnosis, more accurate for determining tumour margins and more sensitive for detecting metastatic disease. Ultrasound provides highly detailed images of parenchymal masses and infiltrative lesions while providing a means for aspiration or biopsy using real-time image guidance. Computed tomography and magnetic resonance-imaging techniques provide exquisite anatomical resolution that improves diagnostic accuracy, provides an accurate means of radiation or surgical treatment planning and a quantitative means for monitoring response to therapy. In addition to traditional anatomic imaging, new techniques are being developed for estimating functional parameters such as tumour perfusion, cell metabolism and gene expression. While conventional planar scintigraphy has been available for some time, newer nuclear imaging modalities such as positron emission tomography promise to further improve the accuracy of initial tumour diagnosis and staging and determination of response to therapy. Although many of these functional techniques are not yet clinically available, it is highly likely that some will be integrated into routine clinical practice in the near future.

“…The first application of laparoscopic ultrasonography in veterinary medicine refers to an abdominal examination on a standing horse, using a 40‐cm long probe passing through a laparoscopic cannula with local anesthesia at the site of cannula–trocar introduction 7 . Laparoscopic ultrasonography was briefly mentioned in the diagnosis of abdominal disorders in dogs and cats 8 …”

The technique was used for systematic exploration of the abdominal cavity during diagnostic laparoscopy procedures and for biopsy guidance.…”

The aim of this study was to describe the technique of laparoscopic ultrasonography in six dogs with intra-abdominal disease. Investigation of the abdominal cavity was undertaken initially in each dog by laparoscopy alone. After exploration and visualization of a diseased organ, a 7.5 MHz microconvex ultrasound probe was introduced into the abdomen through a laparoscopic cannula for videoguided ultrasound examination. Laparoscopic ultrasonography allows core biopsy or needle aspiration to be performed by guiding the needle into nonsuperficial lesions, where videoendoscopic guidance alone is not enough. In addition, color Doppler ultrasonography is useful to examine the vascular pattern to minimize or eliminate complications when a biopsy is performed.
