Bilateral Subcapsular Urinomas: an Uncommon Cause of Page Kidney with Renal Failure

E. Tenisch, E. Uldry, J.-Y. Meuwly, F. Becce

The authors present an unusual case of Page kidney secondary to bilateral subcapsular urinomas and complicated by acute renal failure. The ultrasound (US) and computed tomography (CT) findings are described, with emphasis on the US-guided percutaneous treatment.

Doppler Ultrasound in Obstetrics

H. Steiner, I. Haberlehner, T. Jaeger

Conclusion/Core Statements
- Doppler sonography is an important tool in managing high risk pregnancies.
- Valid results require technical skills and pathophysiological knowledge as well as a careful examination.
- Doppler sonography is used for high risk patients and can reduce perinatal mortality.
- Screening of the uterine artery allows risk evaluation during pregnancy.

Review

Intravenous Application of Second-Generation Ultrasound Contrast Agents in Children: A Review of the Literature

M. Piskunowicz, W. Kosiak, T. Batko

CEUS examinations using second-generation ultrasound contrast agents (UCA) are conducted in children, despite not being registered for individuals less than 18 years of age. The authors searched the Medline® database through Pubmed® and Scopus database for suitable publications. Neither of the analyzed studies included any reports of adverse effects after UCA administration.

Student Tutors Are Able to Teach Basic Sonographic Anatomy Effectively - a Prospective Randomized Controlled Trial

N. Celebi, K. Zwirner, U. Lischner, M. Bauder, K. Ditthard, S. Schürger, R. Riessen, C. Engel, B. Balletshofer, P. Weyrich

Ultrasound is a widely used diagnostic tool. In medical education, it can be used to teach sonographic anatomy as well as the basics of ultrasound diagnostics. Some medical schools have begun implementing student tutor-led teaching sessions in sonographic abdominal anatomy in order to meet the growing demand in ultrasound teaching. The authors investigated whether student tutors teach sonographic anatomy as effectively as faculty staff sonographers.

Contrast-Enhancend Sonography (CEUS) in Pneumonia: Typical Patterns and Clinical Value - a Retrospective Study on n = 50 Patients

H.-N. G. Linde, A. Holland, B. H. Greene, C. Görg

The aim of the study was to describe contrast-enhanced ultrasound (CEUS) patterns of pneumonia, to characterize CEUS patterns and to determine the clinical value of deviant CEUS patterns.

Ultrasound Assessment of Inferior Vena Cava Collapsibility Is Not a Valid Measure of Preload Changes During Triggered Positive Pressure Ventilation: A Controlled Cross-Over Study

P. Juhl-Olsen, C. A. Frederiksen, E. Sloth

The compiled results of this study show that I inferior vena cava collapsibility (IVCc) cannot be held as a valid measure of preload status during positive pressure ventilation. This may be explained by systematic alterations in other determinants for IVCc. Comparison of methods encourages the use of sagittal 2-dimensional echocardiography for dynamic imaging of the inferior vena cava. Sagittal M-mode and transverse 2-dimensional echocardiography overestimate IVCc as compared to sagittal 2-dimensional echocardiography.

The Accuracy of BI-RADS Classification of Breast Ultrasound as a First-Line Imaging Method

H. Hille, M. Vetter, B. J. Hackelöer

The aim was to evaluate the accuracy of BI-RADS categories 3 - 5 in breast ultrasound (US) as the first-line imaging method. The data support the feasibility of US for discriminating malignant from benign findings corresponding to the ACR BI-RADS classification without excessively increasing the number of unnecessary biopsies.

Mesenteric Transit Time Using Contrast-Enhanced Ultrasound (CEUS) Does Not Correlate with Disease Activity in Crohn's Disease

R. S. Goertz, R. Heide, T. Bernatik, M. J. Waldner, J. Mudter, M. F. Neurath, D. Strobel

The authors evaluate the mesenteric transit time (MTT) - measured by contrast-enhanced ultrasound - as a marker for inflammatory activity in Crohn's disease. The MTT decreases in the first two hours after eating. The visually assessed and the software-based MTT correlate well, however MTT does not correlate with disease activity in patients with Crohn‘s disease.

Real-Time Elastography of Hepatic Thermal Lesions In Vitro: Histopathological Correlation

P. Wiggermann, E.-M. Jung, S. Glöckner, P. Hoffstetter, W. Uller, A. Vasilj, A. Schreyer, C. Stroszczynski

To evaluate the reliability of elastography, a new ultrasonographic method, for delineating thermal lesion boundaries in porcine liver tissue by comparing lesion dimensions determined by real-time elastography with the findings at gross pathology.

3D imaging of the fetal face - Recommendations from the International 3D Focus Group

E. Merz, J. Abramovicz, K. Baba, H.-G. K. Blaas, J. Deng, L. Gindes, W. Lee, L. Platt, D. Pretorius, R. Schild, P. Sladkevicius, I. Timor-Tritsch

The purpose of publishing these recommendations was to demonstrate the different possibilities of assessing the normal and abnormal fetal face with 3 D/4 D ultrasound and to give the operator an overview of the benefit resulting from the application of that technology.
