Material und Methoden Es wurden 233 Handgelenke von 153 Patienten untersucht. Die Querschnittsfläche (CSA) des Nervus medianus wurde mit einem Linearschallkopf erhoben. Die WFR wurde errechnet.

Ergebnisse Patienten mit DM und CTS hatten signifikant niedrigere WFR-Werte als Patienten ohne DM mit CTS (p = 0,002). Es gab keinen Unterschied zwischen der WFR von Patienten mit DM und ohne CTS und von Patienten mit DM und mit CTS (p = 0,06). Die diagnostische Genauigkeit zwischen Patienten mit DM und mit CTS und Patienten mit DM und ohne CTS war mit der WFR niedrig (ROC AUC = 0,630, 95 % CI 0,541 – 0,715, p = 0,011).

Schlussfolgerung Die Ergebnisse dieser Arbeit legen nahe, dass die WFR bei Patienten mit DM und CTS eine niedrige diagnostische Genauigkeit hat. Daher sollte sie bei diesen Patienten nur mit Vorsicht verwendet werden.

Kernaussagen Die diagnostische Genauigkeit der WFR ist bei Diabetikern niedrig. Die WFR sollte bei Patienten mit DM nicht verwendet werden. Die sonografische Beurteilung des Nervus medianus sollte bei Patienten mit DM den Schwerpunkt auf morphologische Veränderungen legen.

Purpose Diabetes mellitus (DM) and carpal tunnel syndrome (CTS) are common pathologies. The diagnosis of CTS can be facilitated by the use of an ultrasound-based wrist-to-forearm ratio (WFR) of the nerve diameter. However, the applicability of WFR in DM-patients is not yet clear.

Materials and Methods 233 wrists of 153 patients were examined. Cross-sectional areas (CSA) of the median nerve were obtained using a linear array probe. The WFR was calculated.

Results Diabetics with CTS had significantly lower WFR values than non-diabetics with CTS (p = 0.002). There was no difference between the WFR of diabetics with and without CTS (p = 0.06). The diagnostic accuracy between diabetics with and without CTS was low for measurements of WFR (ROC AUC = 0.630, 95 % CI 0.541 – 0.715, p = 0.011).

Conclusion Our findings suggest that the WFR has a low diagnostic accuracy in diabetic patients with CTS and should be used with caution in those patients.

Nerve entrapment syndromes of the upper extremity are associated with structural abnormalities or by an intrinsic abnormality of the nerve. Nerve entrapment syndromes generally have a typical clinical presentation, and findings on physical examination and in conjunction with electrodiagnostic studies imaging is used to evaluate the cause, severity, and etiology of the entrapment. With the development of high-frequency linear array transducers (12 – 24 MHz), ultrasound (US) is incomparable in terms of spatial resolution to depict morphological aspects and changes in nerves. US can identify the abnormalities causing entrapment, such as fibrous bands, ganglia, anomalous muscles, and osseous deformities, with the advantage of dynamic assessment under active and passive examination. US is a unique diagnostic modality that allows superb visualization of both large and small peripheral terminal nerve branches of the upper extremity and enables the correct diagnosis of various nerve entrapment syndromes.

Background We aimed to study the validity of six published ultrasound criteria for risk stratification of thyroid nodules in the former severely iodine deficient population of Austria.

Methods Retrospective, single centre, observer blinded study design. All patients with a history of thyroidectomy due to nodules seen in the centre between 2004 and 2014 with preoperative in-house sonography and documented postoperative histology were analyzed (n = 195). A board of five experienced thyroidologists evaluated the images of 45 papillary carcinomas, 8 follicular carcinomas, and 142 benign nodules regarding the following criteria: mild hypoechogenicity, marked hypoechogenicity, microlobulated or irregular margins, microcalcifications, taller than wide shape, missing thin halo.

Results All criteria but mild hypoechogenicity were significantly more frequent in thyroid cancer than in benign nodules. The number of positive criteria was significantly higher in cancer (2.79 ± 1.35) than in benign nodules (1.73 ± 1.18; p < 0.001). Thus, with a cut-off of two or more positive criteria, a sensitivity of 85 % and a specificity of 45 % were reached to predict malignancy in this sample of thyroid nodules. As expected, the findings were even more pronounced in papillary cancer only (2.98 ± 1.32 vs. 1.73 ± 1.18, p < 0.001). The six ultrasound criteria could not identify follicular cancer.

Conclusion Our findings support the recently published EU-TIRADS score. Apart from mild hypoechogenicity, the analyzed ultrasound criteria can be applied for risk stratification of thyroid nodules in the previously severely iodine deficient population of Austria.

At the European Society of Paediatric Radiology (ESPR) annual meeting 2017 in Davos, Switzerland, the ESPR Abdominal (gastrointestinal and genitourinary) Imaging Task Force set out to complete the suggestions for paediatric abdominal imaging and its procedural recommendations. Some final topics were addressed including how to perform paediatric gastrointestinal ultrasonography. Based on the recent approval of ultrasound (US) contrast agents for paediatric use, important aspects of paediatric contrast-enhanced US were revisited. Additionally, the recent developments concerning the use and possible brain deposition of gadolinium as a magnetic resonance imaging contrast agent were presented. The recommendations for paediatric use were reissued after considering all available evidence. Recent insights on the incidence of neoplastic lesions in children with testicular microlithiasis were discussed and led to a slightly altered recommendation.
