  • Schwarz T, Sullivan M, Störk CK, Willis R, Harley R, Mellor DJ. Aortic and cardiac mineralization in the dog. Vet Radiol Ultrasound 2002;43(5);419-27. [Abstract]
  • FIG 8. Post mortem photograph of the opened aortic valve and root of a 6-year-old German shepherd dog. Notice the multiple gritty pale protrusions dorsal to the aortic valve in a linear arrangement (arrows). Radiographically, the dog had a moderately mineralized elongated irregular lesion superimposed on the ascending aorta. FIG 9A. Section of the aortic and pulmonic root from the same dog as in Fig. 8. The tunica intima (TI with arrowhead) of the pulmonic root is marked by an arrowhead. Notice foci of calcified material (arrows) and bone (arrowheads) within the tunica media (TM) of the common wall of the roots of the aorta and pulmonary artery. (H&E x 20). FIG 9B. Section of the aortic root from the same dog as in Fig. 8. There are disrupted calcified deposits within a nodule (arrows) and calcification of the elastin sheets in areas of degeneration within the aortic tunica media (arrowheads and inset) (Von Kossa x 100; inset x 400).

  • Figure 5. Intraoperative view of the left rostrotentorial craniotomy of dog 1. Note the intracranial intra-arachnoid cyst wall prior to surgical fenestration (arrow). Figure 6. Intraoperative view of the left rostrotentorial craniotomy of dog 1. Note the intracranial intra-arachnoid cyst cavity following cyst fenestration and hematoma removal (arrow). Figure 7. Intraoperative view of the left rostrotentorial craniotomy of dog 2. Note the intracystic hematoma within the lumen of the intracranial intra-arachnoid cyst (arrow).

  • Szatmari V, Harkanyi Z, Voros K. A review of nonconventional ultrasound techniques and contrast-enhanced ultrasonography of noncardiac canine disorders. Vet Radiol Ultrasound 2003;44(4):380-91. [Abstract]
  • Figure 5. Color blooming artifact. Color Doppler ultrasound images of the hepatic artery of a 7 month-old mixed breed dog, 4 months after partial hepatectomy due to a congenital arterio-portal fistula. A, B and C images were made at the same point, at the hilus of the liver.
(Fig. 5A) Conventional color Doppler ultrasound examination shows the hepatic artery (HA) and the caudal vena cava (CVC). Figure 5. Color blooming artifact. Color Doppler ultrasound images of the hepatic artery of a 7 month-old mixed breed dog, 4 months after partial hepatectomy due to a congenital arterio-portal fistula. A, B and C images were made at the same point, at the hilus of the liver.
(Fig. 5B) Blooming artifact appears in and around the hepatic artery a few seconds after a 4 ml bolus injection of Levovist® (300 mg/ml) using conventional color Doppler mode. The color pixels cover the whole region of the artery; even less information can be gained than without contrast medium. Note that the caudal vena cava remains unenhanced because the microbubbles have not reached the veins; this is the arterial phase. Fig. 5. Color blooming artifact. Color Doppler ultrasound images of the hepatic artery of a 7 month-old mixed breed dog, 4 months after partial hepatectomy due to a congenital arterio-portal fistula. A, B and C images were made at the same point, at the hilus of the liver. 
(Fig. 5C) Using phase inversion second harmonic imaging the blooming artifact is no longer seen, instead aliasing artifact appears in the hepatic artery as a result of the increased Doppler signal intensity. Fig. 6. Color Doppler ultrasound images of a hypoechoic hepatic mass in an 8-year-old intact female English cocker spaniel. A and B images show the same vessel before and after Levovist® injection. 
(Fig. 6A) The unenhanced image shows a small vessel next to the mass. Fig. 6. Color Doppler ultrasound images of a hypoechoic hepatic mass in an 8-year-old intact female English cocker spaniel. A and B images show the same vessel before and after Levovist® injection.
(Fig. 6B) Ten seconds after a 4 ml bolus injection of Levovist® (300 mg/ml) the vessel that supplies the mass becomes evident using phase inversion second harmonic imaging. Spectral Doppler examination revealed that this vessel is an artery with low peripheral resistance. Malignant liver tumors often have an obvious feeding artery in humans. The intralesional vessels also became more evident after contrast injection. Histologically, the lesion had the aspect of a metastasis from an adenocarcinoma of the anal apocrine glands or from a neuroendocrine tumor (e.g. granulosa-cell tumor). Fig. 8. Comparison of non-conventional B-mode and color Doppler images (phase inversion second harmonic imaging)d of a splenic mass of a 15 year-old Dachshund six seconds after a 4 ml bolus injection of Levovist® (300 mg/ml). A and B images were made at the same point. 

(Fig. 8A) On the B-mode image echorich microbubbles can be seen in a dilated vein (arrow). The direction of blood flow can be determined in real time non-conventional B-mode images by looking at the flowing microbubbles (Note: This figure is a non-color image and is therefore not included here. It can be seen on page 387 of the article; caption included here for clarity). 

(Fig. 8B) With the proper reduction of color gain, the non-conventional color Doppler image does not show aliasing artifacts.
