An 8-year-old spayed female Maltese (2.5 kg of body weight) presented with the primary complaint of loud heart murmur and exercise intolerance. Diagnostic imaging revealed severe pulmonic stenosis (peak velocity 5.2 m/s) with right ventricular hypertrophy. The dog revisited after 2 years, at which time, diagnostic imaging revealed severe biventricular hypertrophy, dynamic left ventricular outflow tract obstruction, left atrial dilation and pulmonary hypertension with worsened pre-existing pulmonic stenosis. Postmortem investigation revealed hypertrophic cardiomyopathy and regional myocardial infarction. The case was diagnosed as hypertrophic cardiomyopathy secondary to severe right and left ventricular outflow tract obstruction.

A 13-month-old intact female poodle dog presented with an acute history of circling and seizure episodes. On the basis of the results of neurologic examination combined with magnetic resonance imaging and cerebrospinal fluid analysis (CSF), meningoencephalitis of unknown etiology (MUE) was suspected. Therapy with mycophenolate mofetil plus prednisolone was initiated, following which the clinical signs showed improvement for only one month before gradually worsening again. Acute progression of the clinical disease was observed, and the patient was euthanized 91 days after initial presentation. This case was definitively diagnosed as necrotizing meningoencephalitis (NME) according to the results of post-mortem histopathological examination. This report describes the clinical findings, serial magnetic resonance imaging (MRI) characteristics, and histopathological changes in a case of acute NME.

A 1.83 kg, 9-year-old, spayed female Yorkshire Terrier was referred to the Veterinary Medical Teaching Hospital of Konkuk University for evaluation of an intra-abdominal mass with a week history of vomiting and diarrhea. On physical examination, survey radiography, abdominal ultrasonography, and computed tomography, a huge firm mass was identified in the mid-caudal abdomen. Surgical exploration of the abdominal cavity was performed to remove the mass. The encapsulated mass adhered to the mesentery, tail of the spleen, small intestine, omentum, and right lobe of the pancreas was removed using blunt dissection with dry gauze and cotton swabs. Macroscopic and histopathological examination revealed that the mass was foreign-body granuloma consistent with gauze fiber. Plain abdominal radiography demonstrated no remarkable findings 8 months post-operatively. There was no evidence of vomiting, diarrhea, coughing, difficulty breathing, and cyanosis on exertion 13 months post-operatively.

In the diagnostic ultrasound (US) transducer technology, the high frequency US(HFUS) transducer over 20 MHz is one of the current issues to be pursued for better resolution with the expense of penetration. HFUS single element transducers and the mechanical scanning systems for imaging are reviewed, and HFUS array transducers are also briefly summarized. HFUS applications such as the human applications in ophthalmology and dermatology and small animal applications for research purposes are reviewed with vascular and blood imaging in this paper.

A 12-year-old spayed female dog presented with vomiting and anorexia for four days. Radiographic examination revealed that the small intestines were distended with fecal material. Ultrasound examination showed irregular marginated material with moderate shadowing throughout several segments of the small intestines. Proximal to this intestinal material, small intestines were distended with fluid. The patient underwent one-day of hospitalization, and descent of small bowel fecal materials (SBFMs) was confirmed on radiographs. However, surgical removal was performed due to worsening clinical signs and echogenic changes in the mesentery observed on ultrasound. During surgery, intestinal congestion was observed along with congestion and edema in the surrounding mesentery. Two segments of the small intestines were resected, and feces were found within the resected segments. The patient showed rapid recovery postoperatively and experienced no recurrence. SBFM can induce mechanical intestinal obstruction, and if radiographic evidence of SBFM is observed in patients with vomiting, surgical resection would be considered.

Caudal occipital malformation syndrome (COMS) is relatively common disease which occurs at craniocervical junction. It has been known that this syndrome was developed mainly in Cavalier King Charles spaniels, but these days there are a lot of case reports about COMS in other small breed dogs. In this report, COMS was diagnosed in ten dogs presented to Haemaru Referral Animal Hospital using MRI examination from January 2005 to April 2006. These cases were also investigated about concurrent diseases and syringomyelia was the most common type of complication, but clinical signs were nonspecific. COMS could be controlled by medical therapy with corticosteroid except cases with concurrent meningitis. It is considered that the present report could provide information regarding imaging and clinical features of COMS such as concurrent diseases, clinical signs, and prognosis in small animal practice despite of limited case numbers.

목적: 광학영상기술은 소동물이나 임상연구에서 분자영상법으로 알려진 첨단연구 분야이다. 광학영상기기는 소동물영상연구 및 추적연구에 중요한 역할을 수행하고 있다. 발광영상에서 소동물을 영상화 하기 위해서는 피부조직을 뚫고 나오는 광자를 검출하기 위한 고민감도 CCD카메라가 필요하다. 이 연구에서는 소동물에서 발생하는 발광신호를 검출하기 위해 개발한 광학영상기기를 소개하고자 한다. 대상 및 방법: 냉각형 CCD카메라와 집광렌즈, 8개의 백색광 LED광원을 암실상자 안에 장치하였다. 팬텀 및 튜브를 이용한 영상을 얻은 후 발광 박테리아를 이용하여 CT26 암모델 누드마우스에서 영상을 획득하였다. 결과: 발광영상을 얻기 위한 광학영상기기를 설계하고 개발하였다. 영상획득이 성공적으로 수행되었고, 시스템을 완성하였다. 개발된 장비는 분자영상연구에 사용되고 있다. 결론 개발된 광학영상장비는 다양한 실험적 조건을 만족하는 연구에 최적화하여 유용한 도구로 자리잡을 것으로 기대한다.

Molecular imaging strives to visualize processes in living subjects at the molecular level. Monitoring biochemical processes at this level will allow us to directly track biological processes and signaling events that lead to pathophysiological abnormalities, and help make personalized medicine a reality by allowing evaluation of therapeutic efficacies on an individual basis. Although most molecular imaging techniques emerged from the field of oncology, they have now gradually gained acceptance by the cardiovascular community. Hence, the availability of dedicated high-resolution small animal imaging systems and specific targeting imaging probes is now enhancing our understanding of cardiovascular diseases and expediting the development of newer therapies. Examples include imaging approaches to evaluate and track the progress of recent genetic and cellular therapies for treatment of myocardial ischemia. Other areas include in vivo monitoring of such key molecular processes as angiogenesis and apoptosis, Cardiovascular molecular imaging is already an important research tool in preclinical experiments. The challenge that lies ahead is to implement these techniques into the clinics so that they may help fulfill the promise of molecular therapies and personalized medicine, as well as to resolve disappointments and controversies surrounding the field.
