Review ArticleOpen accessIn the abstractEchocardiography in Infective Endocarditis: An Update on its Usefulness: How, When, How Much and Where?Josep Maria Frigola, Sergio Moral, Pau Vilardell, Ramon BrugadaEchocardiography is the main imaging technique in the diagnosis of Infective Endocarditis (IE). In 85-90% of cases this diagnosis is based on some echocardiographic criteria. Transthoracic echocardiography is an inexpensive test, quickly accessible without side effects, which has become the initial imaging technique of choice in the diagnosis of IE, as well as in the assessment of complications and follow-up. … …American Journal of Infectious Diseases, Vol. 17, Issue 2 · 27 May 2021 · 7,631 accessesView PDFCite
Literature ReviewOpen accessIn the abstractDiagnostic Imaging of Gastrointestinal Tumours in Dogs and Cats: A ReviewFrancesco Simeoni, Francesca Del Signore, Rossella Terragni et al.Gastrointestinal tract tumours in dogs and cats are characterized by non-specific clinical presentation and laboratory abnormalities, but require fast identification, characterization and staging. Imaging techniques play a key role in the diagnostic process of these diseases in routine veterinary practice. Survey and contrast radiography may indicate primary or secondary signs of gastric or intestinal neoplasia such as a wall mass, … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 2 · 15 Apr 2020 · 9,833 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving Medical Imaging and Blood Flow Measurement by using a New Doppler Effect RelationshipFlorian Ion T. PetrescuThe Doppler Effect represents the frequency variation of the waves, received by an observer which is drawing (coming), respectively it’s removing (going), from a wave spring (source). One proposes to study the Doppler Effect for the light waves, generally for the electromagnetic waves. Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842 in … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 14 Oct 2015 · 12,852 accessesView PDFCite
Research ArticleOpen accessIn the abstractTreatment of Ovarian Inactivity in Mares During the Breeding Season with PMSG/hCG, PMSG or GnRH and the Effect of Treatment on Estradiol and Progesterone ConcentrationsMohamed Sabry Medan, Taher Al-DaekThe objective of the present study was to treat ovarian inactivity in mares during the breeding season by using three protocols. Mares (n = 52) kept under field condition in the Green Mountain area, north of Libya were examined transrectally by ultrasound during the breeding season. They were assigned to have inactive ovaries which was confirmed by measuring serum estradiol … …American Journal of Animal and Veterinary Sciences, Vol. 9, Issue 4 · 13 Dec 2014 · 7,562 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Approach to Medical Image SegmentationNandagopalan Shanmugam, Adiga B. Suryanarayana, Sudarshan TSB et al.Problem statement: Segmentation is a vital aspect of medical imaging. It aids in the visualization of medical data and diagnostics of various diseases. Ultrasound image segmentation, in particular echocardiographic image segmentation, is required to identify the regions of interest such as Left Ventricle (LV) and other cardiac cavities. Existing methods do not address the drawbacks of speed and quality of … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 7,214 accessesView PDFCite
Research ArticleOpen accessIn the abstractDWT to Classify Automatically the Placental Tissues Development: Neural Network ApproachMohammad Ayache, Mohamad Khalil, Francois TranquartProblem statement: This study proposed an approach for classification of placental tissues development using ultrasound images. Approach: This approach was based to the selection of tissues, feature extraction by discrete wavelet transform and classification by neural network and especially the Multi Layer Perceptron (MLP). Results: The proposed approach was tested for ultrasound placental images; resulting in 95% success rate. Conclusion/Recommendations: … …Journal of Computer Science, Vol. 6, Issue 6 · 30 Jun 2010 · 6,997 accessesView PDFCite
Research ArticleOpen accessIn the abstractUltrasonographic Evaluation of Transcutaneous Electrical Neural Stimulation on the Repair of Severed Superficial Digital Flexor Tendon in HorsesDavood Sharifi, Dauod Kazemi, Abbas VeshkiniProblem statement: The main aim was to clinical assessment of the ultrasonographic changes of transcutaneous electrical neural stimulation after inducing injury in the SDFT in horses. Approach: Using 8 adults’ castrated horses having 350-550 Kgbw with 4-6 years of age. The left hind limb and right fore-limb Superficial Digital Flexor Tendon (SDFT) were splitted longitudinally at mid metatarsal and metacarpal … …American Journal of Animal and Veterinary Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 7,368 accessesView PDFCite
Review ArticleOpen accessIn the abstractSegmentation Methods of Echocardiography Images for Left Ventricle Boundary DetectionSamaneh Mazaheri, Rahmita Wirza, Puteri Suhaiza Sulaiman et al.Due to acoustic interferences and artifacts which are inherent in echocardiography images, automatic segmentation of anatomical structures in cardiac ultrasound images is a real challenge. This paper surveys state-of-the-art researches on echocardiography data segmentation methods, concentrating on methods techniques developed for clinical data. We present a classification of methodologies for echocardiography image segmentation. By choosing ten recent papers which have … …Journal of Computer Science, Vol. 11, Issue 9 · 6 Dec 2015 · 7,054 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectrotherapeutic Interventions for Tennis Elbow or Lateral Epicondylitis: A Brief Review of the LiteratureLevent Ediz, Mahmut AlpayciLateral Epicondylitis (LE) or tennis elbow is a painful and functionally limiting entity affecting the upper limb and hand. The lack of sufficient understanding regarding its pathophysiology has led to a large number of treatment approaches in physiotherapy practice including electrotherapeutic interventions. In the current review we evaluated recent trials and reviews of electrotherapeutic interventions for LE treatment for evidence … …Physics International, Vol. 3, Issue 2 · 26 Feb 2013 · 7,373 accessesView PDFCite
