Dual-echo ultrashort echo-time CODE pulmonary MRI preliminarily succeeded in generating a positive contrast of iron oxide in rabbits with granulomatous lung disease, by using clinically-usable superparamagnetic iron-oxide nanoparticles, ferumoxytol, which was hardly achievable via conventional T2* MR sequence. This new pulmonary MR imaging biomarker possibly gives a chance to differentiate a benign inflammatory lesion from malignancy.
