HYPOTHESIS Peritonitis is a well-known indication for surgery, but its preoperative cause usually is not established. We hypothesize that abdominal ultrasonography is superior to the clinical impression of the surgeon in detecting the cause of peritonitis. DESIGN A prospective case series. SETTING A major university hospital in Taiwan, Republic of China. PATIENTS AND METHODS One hundred t...

BACKGROUND Differential diagnosis is often difficult for small (</=20 mm) polypoid lesions of the gall bladder. AIM To assess the diagnostic accuracy of endoscopic ultrasonography (EUS) for polypoid lesions in a surgical and follow up series. METHODS A total of 194 patients with small polypoid lesions underwent both ultrasonography and EUS. A tiny echogenic spot or an aggregation of echogen...

As judged by the American College of Radiology Appropriateness Criteria, renal Doppler ultrasonography is the most appropriate imaging test in the evaluation of AKI and has the highest level of recommendation. Unfortunately, nephrologists are rarely specifically trained in ultrasonography technique and interpretation, and important clinical information obtained from renal ultrasonography may no...

OBJECTIVES To create a state-of-the-art overview of the new and expanding role of ultrasonography in clinical decision-making, intervention and management of the upper and lower airways, that is clinically relevant, up-to-date and practically useful for clinicians. METHODS This is a narrative review combined with a structured Medline literature search. RESULTS Ultrasonography can be utilise...

BACKGROUND In veterinary medicine, contrast-enhanced ultrasonography allowed the accurate quantification of liver, splenic and kidney vascularization in healthy dogs and the differentiation between malignant and benign hepatic, renal, and splenic nodules in dogs and cats based on perfusion patterns. The utility of contrast-enhanced ultrasonography in other applications is still under study. The...

Preoperative identification of the components of atherosclerotic plaque was attempted using ultrasonography in five patients and magnetic resonance (MR) imaging in three patients before carotid endarterectomy. The correlation between surgical and histological findings, and preoperative ultrasonography and MR imaging was evaluated. Plaque consisting predominantly of calcification appeared as bri...

Objective- This study refers to the role of ultrasonography in the diagnosis of mammary gland tumor in bitches as a complementary diagnostic method and its ultimate goal is to evaluate the results of mammography with the positive results of ultrasonography. Design- Prospective study. Animals- 12 German Shepherd bitches with swollen mass in the mammary gland region (group I) and 12 h...

Background—DiVerential diagnosis is often diYcult for small (<20 mm) polypoid lesions of the gall bladder. Aim—To assess the diagnostic accuracy of endoscopic ultrasonography (EUS) for polypoid lesions in a surgical and follow up series. Methods—A total of 194 patients with small polypoid lesions underwent both ultrasonography and EUS. A tiny echogenic spot or an aggregation of echogenic spots ...

BACKGROUND AND OBJECTIVE Chest X-ray is recommended for routine use in patients with suspected pneumonia, but its use in emergency settings is limited. In this study, the diagnostic performance of a new method for quantitative analysis of lung ultrasonography was compared with bedside chest X-ray and visual lung ultrasonography for detection of community-acquired pneumonia, using thoracic compu...

PURPOSE Fast MRI has provided detailed and reproducible fetal anatomy. This study was performed to evaluate the usefulness of fetal MRI for prenatal diagnosis. MATERIALS AND METHODS Fifty-six fetuses with congenital abnormalities on ultrasonography were evaluated by fetal MRI from 2001 to 2004 in Severance Hospital. Final diagnosis was made by postnatal pathology, postnatal MRI, and other mod...
