Intracranial rosai-dorfman disease.

Rosai-Dorfman disease (RDD) is a rare, benign pseudolymphomatous condition, predominantly involving lymph nodes. Rosai-Dorfman disease (RDD) (sinus histiocytes with massive lymphadenopathy) rarely affects the intracranial region without involvement of other sites. It is a rare and idiopathic histoproliferation disorder characterized by painless lymphadenopathy. We report a case of 43-year-old male who presented with unconsciousness; MRI was done and right temporofrontal mass was found. Excision was done, and on histopathology it confirmed RDD.

Experimental exploration of mouse kidney imaging with the SR PCI technology.

This paper explores mouse kidney imaging with diffraction enhanced imaging (DEI) and inline outline X-ray imaging (IOXI) technology, and evaluates latent value of kidney imaging with phase contrast imaging technology. In our experiment, spatial resolution and tissue contrast serve as element evaluation and comparison. Images obtained from our experiment exhibit clearly observable contrasts and high resolution, suggesting X-RAY and IOXO are suitable for capturing kidney images. Also, further comparison shows IOXO has a better performance than DEI in capturing microstructures.
