Abstracts Brief Description of the Purpose of the Review of Literature: To illustrate the sonographic findings of the various kinds of gastrointestinal tract abnormalities. Description (S) Condition (S), Method (S) Or Technique (S): We retrospectively reviewed the sonographic findings of various kinds of gastrointestinal tract abnormalities. All sonographic examinations were performed with high frequency linear arrary transducers. All cases were confirmed by surgical resection, biopsy or radiological follow-up study. A variety of sonographic features were identified in various kinds gastrointestinal tract abnormalities. The disease entities include infectious and inflammatory diseases (appendicitis, Crohn disease, ulcerative colitis, tuberculous enterocolitis, diverticulitis, terminal ileitis, typhlitis, epiploic appendagitis, pseudomenbranous colitis, syphilis), ischemic disease, intussusception, benign tumors, malignant tumors (malignant GIST, lymphoma, carcinoma, metastases) and intramural hematoma. Conclusion: Although there was substantial overlap of sonographic findings in the various kinds gastrointestinal tract abnormalities, familiarity with the sonographic findings can assist in making the correct diagnosis.

Brief Description of the Purpose of the Study: Preventive abdominal ultrasound is not formally described in the general medical guidelines for healthy individuals, but it is regular practice in Brazil to use it as an additional tool on the check-up exams. Methods: Abdominal ultrasound exams were performed by a staff of radiologists using Phillips HDI5000 and Toshiba Aplio XG equipments in a population of executives referred by their companies to a check-up in our service. Lifestyle aspects, comorbidities, and other exams were compared to the findings of the ultrasound. Main Results: In 2011, there were 6927 patients with an average age of 43 years. 53% of them had between 30-45 years and 24% were women. 60% were overweight or obese. 14% had metabolic syndrome and 44% had high cholesterol levels. Ultrasound identified steatosis in 34%. Importance of the Conclusions: NASH (Non-alcoholic steatohepatitis), one of the most commom liver diseases in the western countries, can progress to cirrhosis. Recent studies are associating steatosis as an risk factor for diabetes. The diagnosis of steatosis play a role on preventive issues for these cited pathologies and is also an important tool for persuade patients for lifestyle changes.
Brief Discussion of the Case: Null PD.01.011 PD.01.009 Pitfalls in the Ultrasonic Diagnosis of Hepatobiliary and Pancreatic Disorders J. I. Hwang, S. K. Lee Department of Radiology, Taichung Veterans General Hospital, Taichung, Taiwan Brief Description of the Purpose of the Report: To describe the pitfalls of the upper abdominal ultrasonography most often encountered in the daily practice. Medical History: With the improvement of resolution & introduction of color Doppler, transabdominal ultrasonography has played more important role in the diagnosis of hepatobiliary and pancreatic disorders. Many disease entities may be mis-interpreted by sonographers or ultrasonists, such as peripheral nodule near dome or lingual process of liver, caudate lobe lesions, Infiltrating HCC, fatty liver with nodule or focal fatty sparing, regenerating nodule versus small HCC in severe liver cirrhosis, IHD stones with lobar atrophy & hypertrophy, pneumobilia versus pneumoportogram, Mirizzi’s syndrome or cholangiocarcinoma of CBD, pseudotumor caused by collapsed intestinal loops, pancreatic tumor at uncinate process and pseudoaneurysm versus pseudocyst of pancreas. Diagnosis: The most common problems are owing to technical limitations, perceptive errors or patient’s condition such as much gas retention in the gastrointestinal tract. How to resolve these conditions? Experienced hand is the key point. Discussion and Summary of the Case: This pictorial essay will display many interesting cases as mentioned above and share our experience. The young sonographer or radiologist should be familiar with normal anatomy and its different pathological conditions to avoid serious missing diagnosis.

Ultrasound Features of Tumorlike Lesions and Tumors of the Gallbladder : Correlation with CT and MR S. Y. Baek, J. K. Lee Department of Radiology, School of Medicine, Ewha Womans University, Seoul, Republic of Korea Introduction: Ultrasound (US) is the first imaging modality recommended for diagnosis of the gallbladder pathology. The differential diagnosis should be done between tumorlike lesions and tumors of the gallbladder, because the preoperative diagnosis may significantly alter therapy and patient prognosis. Therefore, we reviewed the US features of tumorlike lesions and tumors of the gallbladder and correlated US features with CT and MR findings. Methods Involved: We performed US exams of the gallbladder using either a 2-5 MHz convex transducer or a 5-12 MHz linear transducer on an HDI 5000 unit or IU-22 (Philips Medical Systems, Bothell, WA) ultrasound system. After an overnight fast of 8 to 12 hours, the gallbladder was scanned on longitudinal, oblique and transverse orientation. Discussion: Tumorlike lesions are commonly found in the gallbladder and include several kinds of polyps, adenomyomatosis, xanthogranulomatous cholecystitis. Benign tumors consist of adenomas, glandular cell tumors, gastric heterotopias and pseudotumors. Malignant tumors are carcinomas, metastases, lymphomas and sarcomas. We illustrated US features of each lesion and correlated them with CT and MR findings. Conclusion of the Presentation: US is very effective and informative to diagnose the gallbladder pathology and well correlated with CT and MR imaging.
