Gadolinium oxide nanoparticles enhance MRI contrast
Ultrasmall gadolinium oxide nanoparticles provide strong positive contrast enhancement at clinical magnetic field strengths. For this reason, they are being developed as positive contrast agents for molecular and cellular MRI.

Preop MRI lessens younger women's risk of breast cancer recurrence
By Amerigo Allegretto
Preoperative MRI may lead to lower risk of ipsilateral in-breast recurrence in younger women with newly diagnosed breast cancer.

Images in a 49-year-old patient originally treated for hormone receptor-positive invasive cancer without preoperative MRI who developed bloody nipple discharge two years after surgery. (A) Left mediolateral oblique mammogram shows new grouped pleomorphic calcification (arrow) adjacent to the previous operation site. (B) Transverse ultrasound image shows a 2.3-cm hypoechoic mass (arrows) with calcifications. (C) Axial contrast-enhanced fat-saturated T1-weighted MRI scan shows an irregular, heterogeneously enhancing mass (arrow) in the left breast, adjacent to the operation site. The final pathologic examination confirmed recurrent invasive ductal carcinoma.
