Randomized Controlled Trial
CT-guided stellate ganglion blockade vs. radiofrequency neurolysis in the management of refractory type I complex regional pain syndrome of the upper limb.
To describe and evaluate the feasibility and efficacy of CT-guided radiofrequency neurolysis (RFN) vs. local blockade of the stellate ganglion in the management of chronic refractory type I complex regional pain syndrome (CRPS) of the upper limb. ⋯ • Complex regional pain syndrome is painful, disabling and often refractory to treatment. • Sixty-seven percent of patients had lasting pain relief (2 years) after radiofrequency neurolysis. • Retrospective study showed a significantly higher success rate for radiofrequency neurolysis. • CT guidance is mandatory for a successful and safe procedure.

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.

Comparative Study
Capability of differentiating smokers with normal pulmonary function from COPD patients: a comparison of CT pulmonary volume analysis and MR perfusion imaging.
To compare CT volume analysis with MR perfusion imaging in differentiating smokers with normal pulmonary function (controls) from COPD patients. ⋯ • Detailed information is needed to diagnose chronic obstructive pulmonary disease. • High-resolution CT provides detailed anatomical and quantitative information. • Magnetic resonance imaging is demonstrating increasing potential in pulmonary function imaging. • MR perfusion can distinguish mild COPD patients from controls. • MRI appears more sensitive than CT in identifying early abnormalities amongst controls.

To evaluate image quality (IQ) of low-radiation-dose paediatric cardiovascular CT angiography (CTA), comparing iterative reconstruction in image space (IRIS) and sinogram-affirmed iterative reconstruction (SAFIRE) with filtered back-projection (FBP) and estimate the potential for further dose reductions. ⋯ • Iterative reconstruction techniques significantly improve non-invasive cardiovascular CT in children. • Using half traditional radiation dose image quality is higher with iterative reconstruction. • Iterative reconstruction techniques may allow further radiation reductions in paediatric cardiovascular CT.

To investigate unenhanced postmortem 3-T MR imaging (pmMRI) for the detection of pulmonary thrombembolism (PTE) as cause of death. ⋯ • Postmortem MRI (pmMRI) provides an alternative to clinical autopsy • Fatal pulmonary thrombembolism (PTE) can now be diagnosed using postmortem MRI (pmMRI). • Special attention has to be drawn to the differentiation of postmortem clots.
