The aim of this study was the evaluation of the diagnostic usefulness of ductal or segmental enhancement in dynamic breast MRI. Segmental and ductal enhancement have been established as the breast MRI hallmarks of intraductal breast cancer ( DCIS ); however, the positive predictive value of this ...
Accordingly, the positive predictive value of segmental and linear enhancement is 34% (17/50); the specificity of this criterion is 96% (826/859). For 4/24 (17%) patients, DCIS was visible as segmental or linear enhancement on dynamic breast MRI, whereas no abnormalities were visible on ...
The corresponding partial dierential systems are solved using nite difference stencils. We include experiments both on synthetic data and on DTI-images of the brain. 展开 关键词: DTI DW-MRI Lie groups Perona-Malik diffusion adaptive diffusion scale spaces ...

On the other hand, a significant enhancement of MR has been observed in the non-omhic space-charge limited transport regime9 and under avalanche breakdown10, thus rais- ing problems of fundamental interest and technological relevance, that is, what is the specific carrier dynamics giving rise to...
We present an enhancement method based on nonlinear diffusion filter and statistical intensity approaches for smoothing and extracting 3-D vascular system from Magnetic Resonance Angiography (MRA) data. Our method distinguishes and enhances the vessels from the other embedded tissues. The Expectation Maxim...

Further, as shown in the figure, mounting the transducers on the slider realizes linear drive with no power cables connected to the slider. These two characteristics make the motor suitable for devices used in MRI scanners, especially for those requiring long-stroke linear drive. In this paper,...
