“…These results are comparable to those reported by other authors, [25] although they only reported finding small differences between the two repeated measurements by the same examiner, without specifying the correlation coefficient values or inter-observer reproducibility.…”

“…Various studies have reported reproducible results in the vascularization of complex structures such as the endometrium and the ovary, with very high intra-and inter-class correlation coefficients. [24] Various investigators have studied female periurethral vascularization, but most employed 2D-US, [25] and published their results on periurethral vascularization using 3D-PDA color histograms, with three vascular indices (VI, FI and VFI). However, the big difference with our study is that they took as the periurethral area a threshold of 5 mm instead of 3 mm which we used in our study.…”

Introduction and hypothesis: We tested inter/intra-observer reproducibility of ten different three-D ultrasound (3D-US) pelvic floor variables and endopelvic vascularization using 3D-power Doppler angiography (3D-PDA) as a reliable method to assess pelvic floor status during pregnancy and puerperium. We hypothesized that the method would show good reproducibility. Materials and methods: A prospective study was conducted in two university hospitals, with 162 nulliparous pregnant women evaluated at weeks 12, 28 and 36, and at 48 hours postpartum and three months post-delivery. At each visit, we performed transperineal 3D-US and 3D-PDA of the pelvic floor. Images corresponding to 30 cases were electronically sent between the 2 observers to test the reproducibility of the results. Results: Correlation coefficients > 0.70 for all 10 variables were obtained. Intra-observer reproducibility for each observer was very good, with intra-class correlation coefficients > 0.86. Inter-observer reproducibility of urethral sphincter volume and vascularization, 3D-PDA, VI, FI and VFI measured by VOCAL technique with automatic threshold mode showed good correlation (ICC > 0.80), considered sufficiently high to be clinically applicable. Conclusions: The present study showed good reproducibility and high inter-and intra-observer correlation coefficients for all the variables used to assess the pelvic floor during normal pregnancy and puerperium, including vaginal anterior wall anchors (AWA) as new biometric measures. This makes them reliable parameters for diagnosis and monitoring of pelvic floor disorders in normal pregnancies. We found that use of the VOCAL technique with automatic threshold mode for measurements was superior to the manual mode due to its accuracy and shorter time requirement.

The aim of this study was to evaluate the suitability of synthetic bitch sex pheromones (Eau' De Estrus ® , Synbiotics USA) for the stimulation of the reproductive reflexes in adult male dogs. In experiment I: anoestral bitches were applied synthetic (n=6) or natural (n=6) pheromones and their attractiveness was compared to the attractiveness of bitches in natural oestrus, In experiment II: swabs socked in natural estrual discharge or Eau D'Estrus were presented to male dogs and behavioral arousal (Exp. II a) and changes in blood flow in the penile artery reflecting erection (Exp. II b) were recorded. In experiment III the time dedicated for sniffing in experimental dogs was analyzed in relation to the type of attractant presented (natural estrual discharge or Eau D'Estrus). In all three experiments we observed the signs of sexual arousal, increased blood flow in the penile artery and increased time of sniffing only with natural pheromones. No signs of excitation or changes in penis perfusion were noted after the use of artificial pheromones. Our results did not support the suitability of Eau D'Estrus for male dog sexual stimulation.

“…This function could be also very useful for evaluation of perfusion of lymph nodes, especially during such pathological conditions as lymphoma, when the changes in blood flow within the core and cortical areas are present (17). This function could also be used for blood flow evaluation in the wall of the rural organs, such as the uterus or urethra (42).…”

The aim of this study was to investigate the usefulness of new software Pixel Flux (PXFX) for clinical evaluation of tissue perfusion in the field of reproduction in dogs. The experiment was performed on six adult Beagle dogs. Different organs and tissues of the animals were examined with the MyLab25 Gold ultrasound system. Blood flow in the ovary, testicle, prostate, the ramification of the penile artery, and the network of blood vessels of the pampiniform plexus were examined with the use of colour coded Doppler technique, and obtained data was evaluated with the PXFX software. The more objective digital evaluation of data obtained with colour Doppler sonography through the application of dynamic tissue perfusion measurements provides new opportunities for diagnosis, as well as continuous monitoring of the function of the examined tissues and organs. The use of PXFX software is strongly indicated as a tool in small animal practice as an additional method for evaluation of tissue perfusion, especially in the cases when other methods like pulsed wave Doppler techniques are difficult to be performed.

Abstract: Vascularity differs in different parts of the urethra. Pixel Flux is a valuable tool for providing reproducible quantitative analysis of vascular parameters for the entire urethra.
