To evaluate echo-planar diffusion-weighted MR imaging (DWI) in the differentiation between benign and malignant cervical lymph nodes. ⋯ According to our first experience, DWI using a SSEPI sequence allows reliable differentiation between benign and malignant cervical lymph nodes.

Randomized Controlled Trial
Percutaneous treatment of non-contained lumbar disc herniation by injection of oxygen-ozone combined with collagenase.
To evaluate the therapeutic results of oxygen-ozone combined collagenase injection for the treatment of lumbar disc herniation compared to the surgery. And to explore the role of this minimally invasive treatment as an alternative to disc surgery. ⋯ The combination of the oxygen-ozone with collagenase shows significant reductions in pain and improvements in function at 3 and 12 months, it can be considered as an option for the treatment of non-contained lumbar disc herniation instead of surgery.

Controlled Clinical Trial
Time-of-flight MR angiography at 3T versus digital subtraction angiography in the imaging follow-up of 51 intracranial aneurysms treated with coils.
To compare 3D time-of-flight MR angiography (TOF-MRA) at 3 Tesla (3T) with digital subtraction angiography (DSA) for the evaluation of intracranial aneurysm occlusion after endovascular coiling. ⋯ TOF-MRA at 3T is at least as efficient as DSA for the evaluation of intracranial aneurysm occlusion after endovascular treatment with detachable coils. We suggest that TOF-MRA at 3T might be used as the primary method for imaging follow-up of coiled intracranial aneurysms.

To retrospectively compare immediate and long-term outcome of central venous infusion port inserted via right high versus low jugular vein approaches. ⋯ Right high jugular vein approach can be a feasible alternative to right low jugular vein approach.

To compare lesion conspicuity and image quality between single-shot spin echo echo planar imaging (SS SE-EPI) before, immediately and 5min after intravenous (IV) injection of superparamagnetic iron oxide (SPIO) for detecting and characterizing focal liver lesions (FLLs). ⋯ Non-contrast-enhanced SS SE-EPI was best for lesion detection. SS SE-EPI sequences were not useful for lesion characterization (differentiation between benign and malignant lesions). Unenhanced SS SE-EPI did not allow differentiation especially as many benign FLLs were hyperintense on the highest b-value images. Combining unenhanced and SPIO-enhanced SS SE-EPI performed better but still was not clinically useful due to variable degree of uptake and vascular pooling of SPIO for (especially) benign FLLs. T2w TSE with SPIO-enhancement was needed for characterization.
