To evaluate the relationship of the liver-to-thoracic volume ratio (LiTR) by MRI with postnatal survival in foetuses with isolated congenital diaphragmatic hernia (CDH). ⋯ • Congenital diaphragmatic hernia is usually managed conservatively before surgery soon after delivery • Fetoscopic endoluminal tracheal occlusion (FETO) has been introduced for severely affected foetuses • In conservatively managed CDH, the liver-to-thoracic volume ratio (LiTR) predicted postnatal survival best. • In severe CDH with prenatal FETO, LiTR also helped predict postnatal survival. • LiTR should be integrated into the prenatal decision-making for foetuses with CDH.

This discussion on developments within publishing presents further thought on green, gold and hybrid models of open access. It also discusses some of the advantages and disadvantages which may be encountered by researchers, authors, institutions, scientific organisations and publishers.

The scientific community is becoming increasingly web-based and the role of online communication is continuously expanding. In this setting, one fact and two trends should be considered. The fact is the decision by Britain's government and by the European Union to make all papers deriving from projects that were paid for using public funds freely available online for reading and redistribution (an approach already widely used in the US). The trends are the 'open review' process and the future perspective of having online-only scientific journals; the balance of advantages and disadvantages of such an approach is debated. These factors are challenging the scientific community worldwide and radiological scientific societies should play a relevant role in driving these processes. ⋯ • Research funded by the EU and Britain's government will soon be freely available • The open-review process has started in certain scientific communities, but not yet within radiology • Online communication is increasing its power within the scientific community.

To evaluate glycosaminoglycan-dependent chemical exchange saturation transfer (gagCEST) imaging at 3-T magnetic resonance imaging (MRI) for quantification of glycosaminoglycan (GAG) content in intervertebral discs (IVDs) in patients with low-back pain (LBP). ⋯ The known loss of GAG in the NP with increasing grade of morphological degeneration can be assessed using gagCEST imaging at 3.0 T. The correlation with single Pfirrmann grades and T2 relaxation times only seems to be moderate, indicating a substantial difference in information provided by the techniques.

To describe our initial experience with percutaneous transthoracic needle biopsy (PCNB) of small (≤1 cm) lung nodules using a cone-beam computed tomography (CBCT) virtual navigation guidance system in 105 consecutive patients. ⋯ CBCT virtual-navigation-guided PCNB is a highly accurate and safe diagnostic method for small (≤1 cm) nodules.
