To qualitatively and quantitatively compare the diagnostic value of diffusion-weighted (DW) magnetic resonance (MR) imaging based on standard single-shot echo-planar imaging and readout-segmented echo-planar imaging in patients with breast cancer at 3.0 T. ⋯ DW imaging based on readout-segmented echo-planar imaging provided significantly higher image quality and lesion conspicuity than single-shot echo-planar imaging by reducing geometric distortions, image blurring, and artifact level with a clinical high-field-strength MR imager. Thereby, readout-segmented echo-planar imaging reached a higher diagnostic accuracy for the differentiation of benign and malignant breast lesions.

To determine if focused ultrasound disruption of the blood-brain barrier (BBB) can be safely controlled by using real-time modulation of treatment pressures on the basis of acoustic emissions from the exposed microbubbles. ⋯ This study demonstrates that acoustic emissions can be used to actively control focused ultrasound exposures for the safe induction of BBB disruption.
