To evaluate the diagnostic accuracy of contrast-enhanced dose-reduced 16-slice multidetector-row CT (MDCT) in newborns and infants with fiberoptic bronchoscopically suspected vascular-induced tracheal stenosis. ⋯ Contrast-enhanced dose-reduced 16-slice MDCT is effective for demonstrating the cause of fiberoptic bronchoscopically suspected vascular-induced tracheal stenosis even in very small and severely ill children despite the small contrast media amount and free breathing.

Comparative Study
[Initial results of shoulder MRI in external rotation after primary shoulder dislocation and after immobilization in external rotation].
A change in the strategy for treating primary anterior traumatic dislocation of the shoulder has occurred. To date, brief fixation of internal rotation via a Gilchrist bandage has been used. Depending on the patient's age, a redislocation is seen in up to 90 % of cases. This is due to healing of the internally rotated labrum-ligament tear in an incorrect position. In the case of external rotation of the humerus, better repositioning of the labrum ligament complex is achieved. Using MRI of the shoulder in external rotation, the extent of the improved labrum-ligament adjustment can be documented, and the indication of immobilization of the shoulder in external rotation can be derived. The aim of this investigation is to describe the degree of position changing of the labrum-ligament tear in internal und external rotation. ⋯ In anterior labrum-ligament tears, the axial MRI of the shoulder in external rotation demonstrates a more physiologic position of the glenoid. This may indicate an immobilization of the shoulder in external rotation, which results in a more anatomical healing of the glenoidal tear. Thus, in the case of labrum-ligament tears, MRI in external rotation is becoming indispensable.

Comparative Study
[MR Imaging of the pelvis in the diagnosis of the endometrium in breast cancer patients in tamoxifen therapy].
The purpose of the study was to determine the value of MR imaging of the pelvis in the diagnostic work-up of the endometrium in breast cancer patients in tamoxifen therapy. ⋯ MR imaging might be helpful in the diagnosis of endometrium pathologies during tamoxifen therapy. Therefore, MR imaging of the pelvis could be used as a diagnostic tool in the follow-up diagnosis of the endometrium in breast cancer patients in tamoxifen therapy.

Retrospective analysis of the success and complication rates of chest port implantation via the lateral subclavian vein. ⋯ Ultrasound-guided puncture of the lateral subclavian vein is a safe procedure for the insertion of central venous port catheter systems and had a very low complication rate in our study. For further evaluation of our port placement technique, prospective studies compared to placement through the internal jugular vein are necessary.
