본 논문에서는 급성 복증을 주소로 야간 응급실 내원 시 영상의학과 전문의 부재 등과 관련된, 급성 충수 돌기염 진단을 위한 복부 초음파 검사의 환자 대기 시간과 충수 돌기 절제술 시행까지 환자 대기 시간을 분석한다. 응급실 내원 환자 41.5%에서 초음파 검사 대기 시간은 10시간 이상으로 나타났고, 외래 내원 환자의 45.2%는 수술 대기 시간이 18시간 이상으로 나왔다. 이는 초음파 검사의 대기 시간이 수술 대기 시간에 영향을 미치는 것으로 카이제곱검증에서 유의하게 나왔다(p<0.05). 따라서 본 논문에서는 환자들의 대기 시간을 감소시키기 위한 방법으로 응급실 의료진의 초음파 검사 시행에 따른 유익성과 급성 충수 돌기염의 특징을 이용한 의료 영상 분석, 연구의 필요성을 제안한다.

A 4-year-old spayed female Miniature Pinscher was presented with a 3.5-year history of elevated liver enzymes level. Continuous elevation of liver enzymes was found on repeated blood examinations and the dog was referred for further evaluation. The abdominal ultrasonography revealed that the gallbladder could not be visualized in any plane. The absence of gallbladder was suspected on ultrasonography. Computed tomography (CT) confirmed gallbladder agenesis (GBA). This is the first reported case of diagnosis of GBA in Miniature Pinscher by using CT.

A 5-year-old male German shepherd dog was presented with a 4 day-history of anorexia and depression. Abdominal radiographs showed a large soft tissue mass and loss of serosal detail. Ultrasonographs revealed splenomegaly with the lacy pattern parenchyma, perivenous hyperechoic region at the splenic hilum, and loss of splenic venous flow. Computed tomographic findings included the enlarged non-enhanced spleen except perivenous region at the splenic hilum and a whirled soft tissue mass at the splenic hilum. Exploratory laparotomy confirmed the diagnosis of splenic torsion. Ultrasonographic findings including lacy appearance, hyperechoic perivenous echogenicity and absence of splenic blood flow and CT findings including no or minimal enhancement of the spleen and a whirled appearance of splenic pedicle could be useful for diagnosing isolated splenic torsion in the dog.

Coverage by National Health Insurance (NHI) was expanded in the abdominal imaging area as follows: upper abdominal ultrasound on April 1, 2018, lower abdominal ultrasound on February 1, 2019, and abdominal MRI on November 1, 2019. Many patients can benefit from the expansion of NHI coverage. Newly included diseases for NHI coverage includes liver cirrhosis, gallbladder polyps, hepatic adenoma/dysplastic nodules, pancreatic cysts, autoimmune pancreatitis and bile duct stone disease. However, the expansion of coverage made each examination more complex, including indications, follow-up strategy, the number of examination per patients, the standard images to be acquired, and the standard forms of the radiological report. Therefore, more careful consideration is mandatory when an abdominal imaging examination is prescribed and conducted.

Recently, the increasing use of antenatal high resolutional ultrasonographic studies, and the increasing expertise of sonographers have contributed to the more frequent prenatal detecton of fetal hepatic calcification. Fetal hepatic calcification can arise from peritoneal, ischemic, infectious, neoplastic, and idiopathic causes. There are many reports that the prognosis is good in isolated fetal hepatic calcification without chromosomal aberrations, associated congenital malfomations or other organ abnormalities. We report one case of fetal hepatic calcification diagnosed by prenatal ultrasonography at gestational age of 27 weeks, without chromosomal abnormalities or other associated organ abnormalities, showing good prognosis.

This study were to evaluate risk factors of GB polpy in Busan and Gyeongnam area. This study was performed with patients by abdominal ultrasonography among the patients who came to the P hospital from January to May 2016. Among them, risk factors were analyzed on 399 people at the same time when abdominal ultrasonography and hematological test. The statistical analysis of risk factors related to the GB ployp was performed by independent t-test and chi-square test. In consider of difference verification result for calculations odds ratio about independent variables, multiple logistic regression analysis to conduct verify adequacy by calculating forecasting model from variable. As a result, GB polyp risk factors have relevance to male, HBsAg positive, triglyceride. GB polyp risk factors confirmed to male, HBsAg positive, triglyceride were calculated forecasting model and forecasting probability value. Forecasting probability sensitivity 61.0%, specificity 76.8%, ROC area under curve 0.735 showed, it confirmed validity of forecasting model. When analyzing the GB polyps morphologically, among the GB polyp types observed from abdominal ultrasonography, the hyperechoic and homogeneous pattern with neck was the largest as shown from 27.5% and two GB polyps were shown most from 38%, sizes were shown most by maximum diameter, 5 to 10mm from 53%. As a disease accompany with GB polyp showed mild fatty liver(23%), diffuse hepatopathy(21%).

건강검진에서 혈압, 혈당과 더불어 빠지지 않는 항목이 바로 간 수치다. 흔히 간 수치가 높다 낮다 등으로 표현하는데, 정확한 의미를 아는 사람은 많지 않다. 간 수차(간 효소 수치)는 간이 얼마나 튼튼한지를 나타내는 척도다. 이 같은 간 수치를 알아보는 간 기능 검사는 1차적으로는 소변을 받고 혈액을 뽑으면 된다. 따라서 검사 전 금식은 필수다. 만약 1차 검사에서 이상이 발견되면 2차 혈액 검사를 진행하거나 종양표지자, 복부초음파, CT, MRI, 복강경, 복부혈관조영 등 다양한 방법으로 심층적인 검시를 진행한다. 간은 2/3가 손상돼도 정상기능을 유지하는 반면, 기능을 상실하기 전까지 이렇다 할 증상이 없어 질환을 알아차리기가 쉽지 않다. 그래서 간을 '침묵의 장기'라는 고약한 별칭이 따라붙는 이유다. 간 기능 검사를 통해 수시로 점검하는 길만이 최선이다.

This report describes the normal radiographic and ultrasonographic morphological features of premature minipigs at 4, 8, 12 and 20 weeks of age. Radiographic examination is a simple diagnostic method used to identify the general morphologic state of major organs and their adjacent structures, and to assess the presence of abnormalities. The parameters for evaluation in plain abdominal radiographs are the degree of diffuse serosal margin details, extent of visualization of each organ, their size, shape, and contour, locations of main organs - such as the liver, stomach, spleen, kidneys, urinary bladder - the distribution of the intestines, and assessment of the retroperitoneal space and its contents. Ultrasonographic examinations are used to investigate their internal condition. The parameters for evaluation in abdominal ultrasonography are echogenicity, echotexture, and size and shape of the main organs such as the liver, spleen, kidney, urinary bladder and gastrointestinal tract. Minipigs had similar findings compared to dogs or cats.

Porcelain gallbladder is a rare disorder by deposition of calcium in the wall of gallbladder. The chronic cholecystitis is reported to produce mural calcification and obstruction to the cystic duct by stone. Since porcelain gallbladder is commonly associatedwith gallbladder cancer, cholecystectomy is prerformed to prevent it. We report here a case of a patient with porcelain gallbladder. This case showedthe typical ultrasonogaphic, computer tomogaphic and radiaographic findings of the disease.
