전신 뼈 검사에서 46명의 환자(남:여=39:7)가 미만성 간 섭취를 보였다. 추적 전신 뼈 검사를 시행하였으며, 이전에 보였던 미만성 간 섭취는 모두 소실되어 정상적인 소견을 보였다. 간기능 및 신기능 검사는 모두 정상이었다. 전신 뼈 검사에서 $^{99m}Tc$-DPD의 미만성 간 섭취에 MRI 조영제가 간접적인 영향을 주고 있다. $^{99m}Tc$-DPD의 미만성 간 섭취를 피하기 위해서 전신 뼈 검사는 MRI 조영제를 사용한 검사를 시행하기에 앞서서 먼저 시행하여야 하고, MRI 조영제를 사용한 검사가 있을 경우에는 조영제가 몸에서 제거된 후... -

Az 값이 유의하게 낮았으며(<1 cm, p=0.034; 1-2 cm, p=0.045) MRI 단독 판독과 비교하여서는 유의한 차이를 보이지 않았다. 위양성율에 있어서는 CT 단독 판독의 경우, CT와 MRI의 종합 판독과 비교하여 A그룹에서 유의하게 높은 결과를 보였다 (28 %, p=0.023). 결론 : 대장암 환자에서 병기결정에 있어서 일반적으로 행해지는 나선형 CT 외에 부가적 Mn-DPDP 조영증강 MRI는 2 cm 미만의 간 병변의 감별에 있어 유용하며, 특히 1cm 미만의 작은 간 전이 발견에 있어서는 CT 또는 MRI 단독 판독의 경우보다 발견율을 높일 수 있어서... -

T MRI 시스템을 실험에 사용하였다. 3.0 T MRI 시스템 안에 뇌전도 캡을 쓴 피험자를 놓고 EPI 촬영을 하면서 뇌전도 신호를 측정하였다. 측정된 뇌전도 신호에 대하여 ICA를 적용해 경사자계 유발 잡음을 선택적으로 제거하였다. 제거한 결과를 평균화 방법과 PCA 방법을 사용해 얻은 결과와 비교하였다. 결과: ICA 방법, 평균화 방법 , PCA 방법 모두 경사자계 유발잡음 제거에 있어 일정 부분 효과가 있었다. 그러나 이들 방법들을 상호 비교하였을 때 잡음 제거 결과는 ICA 방법이 평균화 방법과 PCA 방법에 비해 우수하였다. 결론:... -

scan delay of 30 sec after the bolus trigger. For the injection protocol used in this study, the optimal scan delay times for renal arterial, corticomedullary, and nephrographic phases were 5, 10, and 30 sec after triggering at 100 HU of aortic enhancement using the bolus-tracking technique. The bolus-tracking technique is useful in multi-phase renal CT study as it compensates for different transit times to the kidney among different animals, requires a small dose of contrast media, and does not... -

Two cats were presented with vestibular signs and seizures. Both cats were diagnosed with thiamine deficiency. The transverse and dorsal T2-weighted magnetic resonance (MR) images revealed the presence of bilateral hyperintense lesions at specific nuclei of the midbrain, cerebellum, and brainstem. After thiamine supplementation, the clinical signs gradually improved. Repeated MR images taken 3 weeks after thiamine supplementation had started showed that the lesions were nearly resolved. This... -

목적: 3.0 Tesla와 같은 고 자장에서 고해상도의 나선주사영상을 얻기 위해서는 주자장을 균일하게 만들어야 한다. 특히, 나선주사영상인 경우 스핀-에코펄스 시퀀스(SE)나 경사자계 에코 펄스 시퀀스(GE)에 비하여 측정 시간이 길기 때문에 주자장이 균일하지 못하다면, off-resonance 현상으로 영상의 blur가 심해진다. 본 연구에서는 빠른 시간 안에 주자장을 균일하게 할 수 있는 고차(Higher-order) shimming방법을 모색했다. 대상 및 방법: 3 Tesla 자기 공명 영상시스템에서 고해상도의 나선주사영상을 얻기에 적합할 정도의... -

imaging (MRI) and spectroscopy. Eleven adult beagle dogs were anesthetized and underwent magnetic resonance examination of the cranial abdomen by performing morphologic, modified Dixon (mDixon) dual gradient echo sequence, and proton magnetic resonance spectroscopy (1H MRS) imaging. In addition, ultrasonographic liver examination was performed, fine-needle liver aspirates and liver biopsies were obtained, and hepatic triglyceride content was assayed. Ultrasonographic, cytologic, and histologic... -

This study was carried out to derive and evaluate reference computed tomography (CT)-based indices for normal canine spine. CT and magnetic resonance images were acquired from 12 clinically normal Beagle dogs (normal group) and 50 dogs with 56 spinal disorders (patient group). Image acquisition regions were cervical spine (C2-T1), thoracic spine (T1-T13), and lumbar spine (L1-L7). Measured indices were: the ratios of width to height of the spinal cord including the dura matter (CR) and of the... -

Ureteral jets are the result of a forceful ejection of urine from the vesicoureteral junction into the urinary bladder. By using color Doppler ultrasonography (US), we aimed to identify distinct ureteral jets in dogs, provide insight into ureteral obstruction, and facilitate study of urodynamics and vesicoureteric sphincter function via pulsed Doppler US. Color Doppler US was applied to detect urinary flow from the right ureteral orifices in eight healthy beagles. Under anesthesia, 0.9% saline... -

(MRI) and radiograph contrast as diagnostic imaging tools. A total of ten clinically normal beagle dogs and eight clinically normally cats were included. General radiography with contrast, ultrasonography and low-field MRI scans were performed. The visualization of anal sacs, which are located at distinct sites in dogs and cats, is possible with a contrast study on radiography. Most surfaces of the anal sacs tissue, occasionally appearing as a hyperechoic thin line, were surrounded by the... -

대한수의학회 Journal of Veterinary Science 2015, 제 16권 제 2호 5 165-171 (7 pages)
Imaging techniques have been introduced to assess the efficacy and toxicity of developing pharmaceuticals. The purpose of this study was to perform a comprehensive characterization of collagen-induced arthritis (CIA) in rats using micro-computed tomography (micro-CT) and to compare the results with data from conventional pathological examination. Arthritis was induced by collagen in 24 female Wistar rats. Micro-CT and pathological analyses were performed to assess arthritis progression. Micro-CT... -

대한수의학회 Journal of Veterinary Science 2014, 제 15권 제 1호 18 157-161 (5 pages)
Positron emission tomography (PET) using 2-deoxy-2-[F] fluoro-D-glucose (FDG) as a radioactive tracer is a useful technique for in vivo brain imaging. However, the anatomical and physiological features of the Harderian gland limit the use of FDG-PET imaging in the mouse brain. The gland shows strong FDG uptake, which in turn results in distorted PET images of the frontal brain region. The purpose of this study was to determine if a simple surgical procedure to remove the Harderian gland prior to... -
Sporozoite proteome analysis of Cryptosporidium parvum by one-dimensional SDS-PAGE and liquid chromatography tandem mass spectrometry
AMAM Zonaed Siddiki* 대한수의학회 Journal of Veterinary Science 8 Pages
대한수의학회 Journal of Veterinary Science 2013, 제 14권 제 2호 1 107-114 (8 pages)
Despite the development of new technologies, new challenges still remain for large scale proteomic profiling when dealing with complex biological mixtures. Fractionation prior to liquid chromatography tandem mass spectrometry (LC-MS/MS) analysis is usually the preferred method to reduce the complexity of any biological sample. In this study, a gel LC-MS/MS approach was used to explore the stage specific proteome of Cryptosporidium (C.) parvum. To accomplish this, the sporozoite protein of C.... -

Youngkwon Cho, Jimo Jeong, Haebeom Lee, Minsu Kim, Namsoo Kim, Kichang Lee* 대한수의학회 Journal of Veterinary Science 6 Pages
대한수의학회 Journal of Veterinary Science 2012, 제 13권 제 4호 12 419-424 (6 pages)
The feasibility of virtual otoscopy (VO) imaging was evaluated in five dogs with experimentally induced otitis media, two control dogs, and two canine patients with otitis media. VO images of the tympanic cavity and ossicles were generated with commercially available software using raw computed tomography (CT) data. Eight out of 10 ears inoculated with pathogen exhibited obvious clinical signs associated with otitis externa. CT images revealed soft tissue density material occupying the tympanic... -

대한수의학회 Journal of Veterinary Science 2011, 제 12권 제 1호 13 91-94 (4 pages)
Computed tomography (CT) exams were conducted to determine the distribution of abdominal fat identified based on the CT number measured in Hounsfield Units (HU) and to measure the volume of the abdominal visceral and subcutaneous fat in minipigs. The relationship between the CT-based fat volumes of several vertebral levels and the entire abdomen and anthropometric data including the sagittal abdominal diameter and waist circumference were evaluated. Moreover, the total fat volumes at the T11,... -
Computed tomographic characteristics of acute thoracolumbar intervertebral disc disease in dogs
Changyun Lim, Oh-Kyeong Kweon, Min-Cheol Choi, Jihye Choi, Junghee Yoon, * 대한수의학회 Journal of Veterinary Science 7 Pages
대한수의학회 Journal of Veterinary Science 2010, 제 11권 제 1호 11 73-79 (7 pages)
Forty canine patients with a presumptive diagnosis of the intervertebral disc herniation at the thoracolumbar region were imaged. A neurological examination was performed and all patients were classified under four grades by the examination. The degrees of attenuation of the herniated disc material were measured in Housefield units (HU) in each image. The ratio of the area to herniated disc material and the height to disc material were measured. The clinical grade was correlated with the area...
