To evaluate the effect of monophasic combined oral contraceptive pill (COCP) and menstrual cycle phase in healthy young women on white matter (WM) organization using diffusion tensor imaging (DTI). ⋯ An important part in the limbic system, the fornix, regulates emotional processes. Differences in diffusion parameters in the fornix may contribute to behavioural alternations related to COCP use. This finding also suggests that the use of oral contraceptives needs to be taken into account when designing DTI group studies.

This study sought to evaluate whether the therapeutic effects of an anti-inflammatory drug such as minocycline could be monitored by serial ultrasmall superparamagnetic particles of iron oxide (USPIO)-enhanced MRI in experimental stroke. ⋯ This study showed that the extent of signal abnormalities on R2 maps can be used as a surrogate marker to detect minocycline effects in a murine experimental model of stroke.

To evaluate percutaneous computed tomography (CT)-guided intracystic and intra-articular steroid injections for the treatment of lumbar facet joint cyst causing radicular pain. ⋯ Lumbar facet joint cysts are a common feature of back and radicular pain. They may be treated effectively by interventional radiologists using CT guidance. Percutaneous treatment using double injections can save surgery in 75% of patients.

To evaluate the safety and efficacy of magnetic resonance-guided focused ultrasound (MRgFUS) to treat facet joint osteoarthritis pain. ⋯ Magnetic resonance-guided focused ultrasound offers non-invasive therapy for facet joint pain. MRgFUS appears to be an effective and safe thermal ablation technique for facet joint pain. Real-time image control and thermal feedback minimise complications. MRgFUS allows outpatient management of facet joint osteoarthritic low back pain.

To investigate the diagnostic value of whole-body magnetic resonance imaging (MRI) including diffusion-weighted imaging with background signal suppression (DWIBS) for preoperative assessment of non-small-cell lung cancer (NSCLC) in comparison to (18)F-fluorodeoxyglucose (18)FDG) positron emission tomography/computed tomography (PET/CT). ⋯ Numerous radiological methods are available for the crucial staging of lung cancer. Whole-body DWIBS MRI provides comparable results to PET/CT in NSCLC staging. No evident superiority of whole-body DWIBS over PET/CT in NSCLC staging. Challenges for both techniques are T-staging and detection of small metastases.
