  • Ultrasonographic Features of the Heart and Lungs of Captive Reticulated Pythons (Python reticulatus, Schneider 1801) (Reptilia: Squamata: Pythonidae) with Granulomatous Pneumonia and Myocarditis
    The Philippine Journal of Veterinary Medicine, 2017
    Co-Authors: Rizza Elaine B. Lampa, Jezie A Acorda, Emilia A. Lastica-ternura, Arville Mar Gregorio A. Pajas
    Abstract:

    Twelve adult reticulated pythons diagnosed with granulomatous pneumonia and myocarditis were utilized to examine the ultrasound features of the heart and lungs using an ultrasound machine equipped with a 6.5 MHz linear Array Scanner. B-mode and M-mode ultrasonograms were obtained and digital analysis was conducted to calculate the echo mean values. Echocardiographic features and echo mean values were determined and compared to data on apparently healthy reticulated pythons. Higher B-mode measurements of the left atrial internal diameter and circumference of pulmonary trunk, left aortic and right aortic arches were obtained. Higher M-mode values for amplitude measurements for left atrium, right atrium, sinus venosus, pulmonary trunk, left aortic artery, right aortic artery, cavum venosum and cavum arteriosum; and base measurements for all cardiac structures were also observed. Increased echo mean values indicated higher echogenicities of all the cardiac structures. Increased echocardiographic measurements were higher indicating pathologic changes. Echocardiography was found useful in detecting cardiac pathologic changes which can be associated with granulomatous pneumonia and myocarditis. Because of reverberations observed in all lung ultrasonograms, the study determined that ultrasonography cannot be used in detecting small lung lesions in cases of mild to moderate pneumonia.

  • ULTRASONOGRAPHIC FINDINGS IN THE LIVER, GALLBLADDER AND KIDNEYS OF CAPTIVE RETICULATED PYTHONS ( Python reticulatus , SCHNEIDER, 1801) (REPTILIA: PYTHONIDAE) WITH PNEUMONIA
    Philippine Journal of Veterinary and Animal Sciences, 2016
    Co-Authors: Cherry Ann A. Samaniego, Jezie A Acorda, Emilia A. Lastica-ternura, Arville Mar Gregorio A. Pajas
    Abstract:

    Ultrasonography was performed using a 6.5 MHz linear Array Scanner in order to determine the ultrasonographic features of the liver, gallbladder and kidneys of 12 captive reticulated pythons with pneumonia in comparison with macroscopic findings. The organs were examined using an ultrasound machine equipped with a 6.5 MHz Scanner and echo mean values were calculated. The liver appeared elongated with a hypoechoic parenchyma and a large anechoic central hepatic vein with a hyperechoic wall. The gallbladder was observed as a large elliptical structure with a hypoechoic wall and an anechoic lumen. The kidneys appeared as hypoechoic granulated, elongated structures with the right kidney located more cranially than the left. No differences were observed between ultrasonographic and gross measurements of the different organs. Histogram analysis showed that there was a distinct increase in the Emean values of all structures, except the kidneys which showed decrease in Emean values. The results suggest that pneumonia causes changes in the echogenicity of the liver, gallbladder and kidneys in reticulated pythons.

  • ultrasound features and echo mean values of the heart liver and stomach in the philippine tarsier carlito syrichta linnaeus 1758 shekelle and groves 2010 mammalia primates tarsiidae
    The Philippine Journal of Veterinary Medicine, 2014
    Co-Authors: April May L Arcamogentica, Jezie A Acorda
    Abstract:

    The ultrasound features and echo mean values of the heart, liver and stomach of apparently healthy Philippine tarsiers (Carlito syrichta) were determined according to sex (4 males and 4 females), age (4 adults and 4 juveniles) and source (5 captive-bred and 3 wild) using an ultrasound machine equipped with a 7.5 MHz linear-Array Scanner. The heart appeared as an anechoic, rapidly contracting ovoid structure. Adults had significantly higher mean cardiac dimensions than juvenile tarsiers. Wild tarsiers had significantly higher echo mean values of the heart chamber than captive-bred animals. The liver appeared homogenously hypoechoic with some anechoic areas. The stomach had anechoic lumen with hyperechoic wall. Adults had significantly higher stomach mean length than juveniles but no significant differences in the echogenicity of the stomach lumen according to age, sex and source of tarsiers were observed. Results of the study could be used as baseline data for the ultrasound features of heart, liver, Philipp. Key words: digital analysis, heart, liver, Philippine tarsier, stomach, ultrasound

  • ultrasonic imaging and sonographic digital analysis of the kidneys and urinary bladder in the philippine tarsier carlito syrichta linnaeus 1758 shekelle and groves 2010 mammalia primates tarsiidae
    The Philippine Journal of Veterinary Medicine, 2013
    Co-Authors: April May L Arcamogentica, Jezie A Acorda
    Abstract:

    The purpose of this study was to describe the ultrasonographic features and determine the echogenicity of kidneys and urinary bladder according to sex, age and source of Philippine tarsiers (Carlito syrichta). The examination was done using a veterinary ultrasound machine equipped with a 7.5 MHz linear-Array Scanner. Eight apparently healthy Philippine tarsiers (three caught from the wild and five captive-bred) were examined. The kidneys appeared as bean-shaped with anechoic renal medulla, hypoechoic renal cortex, hyperechoic renal pelvis and a thin hyperechoic renal capsule. The dimensions of the kidneys showed larger size in adults, females and wild tarsiers. The echogenicity of the kidney showed that the renal pelvis had the highest echo mean values, followed by the renal cortex and renal medulla. The urinary bladder had anechoic lumen with defined hypoechoic walls. The dimensions of the urinary bladder showed a larger size among adults, females and wild tarsiers. Echo mean values showed that the urinary bladder lumen of juveniles, females and wild tarsiers were more echogenic. Results of the study could be used as baseline data for the ultrasound features of kidneys and urinary bladder for diagnosis of diseases and disorders of these organs in Philippine tarsiers. Key words: echo histogram, kidneys, Philippine tarsier, ultrasound, urinary bladder

  • Ultrasonographic Features of the Reproductive Organs of Captive Asian Reticulated Pythons, Python reticulatus (Schneider, 1801) (Reptilia: Squamata: Pythonidae)
    The Philippine Journal of Veterinary Medicine, 2011
    Co-Authors: Kayceeline L. Enriquez, Emilia A. Lastica, Jezie A Acorda
    Abstract:

    The position, ultrasound features, dimension and echogenicity of the ovarian follicles, testes, hemipenes and vaginal sacs were determined in 12 apparently healthy reticulated pythons (8 females; 4 males) using an ultrasound machine equipped with a 5.0 MHz linear Array Scanner. The ultrasonograms were subjected to digital analysis to obtain the echo mean values for the different organs examined. The ovarian follicles in different stages of development were located laterally on both sides within the caudal half of the body in all female samples. Round, anechoic pre-vitellogenic follicles; homogenous, hypoechoic to hyperechoic vitellogenic follicles; vitellogenic follicles undergoing regression; and hyperechoic postovulatory follicles or eggs in varying degrees of calcifcation were observed. Ultrasonograpic images of the testes revealed homogenous and moderately echogenic structures with mean length of 5.5±1.30 cm and width of 1.6±0.42 cm. The hemipenes and vaginal sacs appeared as acute triangular, uniformly hyperechoic areas surrounded by anechoic to hypoechoic border. The hemipenes (mean length: 6.36±0.46 cm; mean width: 0.51±0.19 cm) in males appeared longer than the vaginal sacs (mean length: 2.92 & plusmn;0.53 cm; mean width: 0.50±0.15 cm) in females. No differences in the echo mean values between the different organs were observed. The results of this study indicate that ultrasonography can be used for visualization and assessment of the ovarian follicles, testes, hemipenes and vaginal sacs in male and female reticulated pythons. Diagnostic ultrasound scanning can be helpful in detecting abnormalities, determining gender and assessing ovarian status for determination of the best time for breeding.

  • Effectiveness of ultrasonography in determining medial and lateral orbital wall fractures with a curved-Array Scanner.
    Journal of oral and maxillofacial surgery : official journal of the American Association of Oral and Maxillofacial Surgeons, 2004
    Co-Authors: Siegfried Jank, Rüdiger Emshoff, H. Strobl, M. Etzelsdorfer, A. Nicasi, B. Norer
    Abstract:

    Abstract Purpose The purpose of the study was to evaluate the diagnostic value of ultrasonography to determine medial and lateral orbital wall fractures. Materials and methods Sixty-two patients with the clinical diagnosis of an orbital trauma underwent coronal computed tomography (CCT) and ultrasonographic investigation (US). Inclusion criteria were clinically suspected orbital injuries defined by reduced bulbus motility, diplopia, or additional traumatic injuries of the orbit or the globe. US and CCT were used as imaging diagnostic methods. Results Ultrasonography showed a sensitivity of 56%, a specificity of 95%, and an accuracy of 88% at the medial orbital rim. Regarding the lateral orbital rim, ultrasonography showed a sensitivity of 92%, a specificity of 88%, and an accuracy of 90% using CCT as a reference method. Conclusion Ultrasonography with a curved-Array Scanner seems to be a valuable method in the detection of lateral orbital wall fractures. Further studies have to be done to improve sensitivity in the interpretation of medial orbital wall fractures.

    Abstract:

    Fragestellung Ziel der Arbeit war es, den diagnostischen Wert der Sonographie mit einem gekrümmten Sektorschallkopf in der Diagnostik von medialen und lateralen Orbitawandfrakturen zu bestimmen. Material und Methode 53 Patienten mit der klinischen Diagnose einer Orbitafraktur wurden über einen Zeitraum von 16 Monaten prospektiv mittels CT und Sonographie untersucht. Als Referenz wurde der intraoperative Befund herangezogen. Ergebnisse Die sonographische Untersuchung der medialen Orbitawand zeigte eine Sensitivität von 80% und eine Spezifität von 96%, während das CT eine Sensitivität von 100% und eine Spezifität von 96% erzielen konnte. Die Unterschiede waren jedoch nicht signifikant ( p =0,402). Bei der Untersuchung der lateralen Orbitawand erzielte die Sonographie eine Sensitivität von 97% und eine Spezifität von 95%, während der CT-Befund eine Sensitivität von 88% und eine Spezifität von 87% erreichte. Die sonographischen Ergebnisse waren signifikant besser als die CT-Befunde ( p =0,008). Schlussfolgerung Die Sonographie mittels eines gekrümmten Sektorschallkopfs kann eine Ergänzung zur CT-Diagnostik von Frakturen der medialen und lateralen Orbitawand darstellen. Weitere technische Verbesserungen der Schallköpfe sind erforderlich, um die Sensitivität der Sonographie bei der Untersuchung der medialen Orbitawand zu steigern. Purpose The purpose of the study was to evaluate the diagnostic value of a curved Array Scanner in the diagnosis of medial and lateral orbital wall fractures.

The intraoperative findings were used as a reference. Results CT reached a sensitivity of 100% and a specificity of 96% in the diagnosis of medial orbital wall fractures, while ultrasound yielded a sensitivity of 80% and a specificity of 96%. There was no significant difference found between CT and ultrasonography ( p =0.402). In the investigation of lateral orbital wall fractures, CT reached a sensitivity of 88% and a specificity of 87%, while ultrasonography yielded a sensitivity of 97% and a specificity of 95%. Ultrasonography achieved significantly better results than CT ( p =0.008). Conclusion The ultrasound investigation with a curved Array Scanner could be used as an additional method in the diagnosis of medial and lateral orbital wall fractures. Further technical improvements of the transducers need to be developed to increase the sensitivity of ultrasound in the diagnosis of medial orbital wall fractures.
