Feasibility study to evaluate whether a diagnostic pediatric MRI scan of the brain can be performed without sedation by using BLADE sequences with rotating blade-like k-space covering. ⋯ Age-adjusted preparation and implementation of a pediatric cranial MRI may reduce the need for sedation. BLADE sequences abate motion artefacts thus enabling acquisition of diagnostic images even in young children. In patients older than 3 years, performance of MRI scans without sedation should be considered.

To evaluate the diagnostic accuracy of qualitative descriptors alone and in combination for the classification of focal liver lesions (FLLs) suspicious for metastasis in gadolinium-EOB-DTPA-enhanced liver MR imaging. ⋯ The combination of qualitative lesion descriptors proposed in this work revealed high diagnostic accuracy and interobserver agreement in the differentiation of focal liver lesions suspicious for metastases using Gd-EOB-DTPA-enhanced liver MRI.

Randomized Controlled Trial Comparative Study
[CT-guided marking of pulmonary nodules with a special lung marking wire before video-assisted thoracoscopic surgery - review of 184 cases].
Minimally invasive techniques like video-assisted thoracoscopic surgery (VATS) are currently the method of choice for the resection of small pulmonary nodules, when they are located in the periphery of the lungs. To guarantee quick and safe intraoperative identification of the nodule, preoperative marking is necessary and sensible. We report about our experiences in 184 markings with a special lung marking wire, which is placed in or around the pulmonary nodule using CT guidance. ⋯ CT-guided marking of pulmonary nodules using a special marking wire followed by thoracoscopic resection is an efficient and safe method for diagnosing suspicious nodules in the periphery of the lung.
