Imaging of metastatic lymph nodes by X-ray phase-contrast micro-tomography. [PDF]

PLoS ONE, 2013
Invasive cancer causes a change in density in the affected tissue, which can be visualized by x-ray phase-contrast tomography. However, the diagnostic value of this method has so far not been investigated in detail.
