To retrospectively evaluate the diagnostic performance and complications of a CT-guided core needle cutting biopsy of mediastinal nodes through a transpulmonary approach. ⋯ • CT-guided core needle biopsy is an accurate technique for diagnosing mediastinal nodes. • The rates of complications are similar to those for pulmonary lesion biopsy. • Pneumothorax risk factors include distance from pleura to target lesion and number of visceral pleura. • Distance from pleura to target lesion is the risk factor for hemoptysis. • CT-guided core needle biopsy is an important diagnostic method for mediastinal nodes.

Noninvasive IDH1 mutation estimation based on a quantitative radiomics approach for grade II glioma.
The status of isocitrate dehydrogenase 1 (IDH1) is highly correlated with the development, treatment and prognosis of glioma. We explored a noninvasive method to reveal IDH1 status by using a quantitative radiomics approach for grade II glioma. ⋯ • Noninvasive IDH1 status estimation can be obtained with a radiomics approach. • Automatic and quantitative processes were established for noninvasive biomarker estimation. • High-throughput MRI features are highly correlated to IDH1 states. • Area under the ROC curve of the proposed estimation method reached 0.86.

Our aim was to determine the prevalence of tuberculosis (TB), the number needed to screen (NNS), and the diagnostic accuracy of chest X-ray (CXR) screening to detect active pulmonary TB during the 2015 European refugee crisis. ⋯ • Prevalence of pulmonary tuberculosis (TB) among refugees in 2015 was low (0.103%). • The number needed to screen to detect one case of active pulmonary TB was 1749. • Tuberculosis X-ray screening resulted in a low sensitivity and high specificity. • Tuberculosis X-ray screening during the European refugee crisis is of low yield. • Improved screening algorithms are needed due to the overwhelming the number of refugees.

To retrospectively assess the safety and efficacy of percutaneous vertebroplasty (PVP) for painful osteolytic spinal metastases when treating more than three vertebrae per session. ⋯ • Percutaneous vertebroplasty is safe and effective for painful osteolytic spinal metastases. • Multilevel vertebroplasty does not cause more complications than single-level vertebroplasty. • Multiple spinal metastases patients may regain functional independence after multilevel vertebroplasty.
