To determine the CT and MR imaging features of ossifying fibroma with aneurysmal bone cyst of the paranasal sinus. ⋯ Fluid-fluid levels within an elliptic-shape mass with scattered calcifications or ground-glass appearance is highly suggestive of this complicated entity in the paranasal sinus.

Volumetric MR-HIFU ablation of uterine fibroids: role of treatment cell size in the improvement of energy efficiency.
To evaluate the energy efficiency of differently sized volumetric ablations in MR-guided high-intensity focused ultrasound (MR-HIFU) treatment of uterine fibroids. ⋯ Energy efficiency in volumetric MR-HIFU ablation of uterine fibroids improves with increased treatment cell size, independent of other significant contributors such as distance of ultrasound propagation or signal intensity of the tumor on T2-weighted MR imaging.

The present work illustrates the current state of image quality and diagnostic accuracy in a new hybrid BrainPET/MR. ⋯ The hybrid BrainPET/MR allows for molecular, anatomical and functional imaging with uncompromised MR image quality and a high accordance of PET results between PET/MR and PET/CT. These results justify the application of this technique in further clinical studies and may contribute to the transfer into whole-body PET/MR systems.

Feasibility of MRI-guided high intensity focused ultrasound treatment for adenomyosis.
To test the feasibility of MRI-guided high intensity focused ultrasound ablation for adenomyosis. ⋯ Based on the results from this study, MRIgHIFU treatment appears to be a safe and feasible modality to ablate adenomyosis lesion and alleviate its symptoms.

To quantify muscular micro-perfusion and arterial perfusion reserve in peripheral arterial disease (PAD) with dynamic contrast-enhanced ultrasound (CEUS) and transient arterial occlusion. ⋯ Dynamic CEUS with transient arterial occlusion quantifies muscular micro-perfusion and arterial perfusion reserve. The technique is accurate to diagnose PAD.
