Fig. 6From: 18F–FDG-PET/CT and diffusion-weighted MRI for monitoring a BRAF and CDK 4/6 inhibitor combination therapy in a murine model of human melanomaTumor cell proliferation and microvascular density in representative tumor sections. Left column: therapy. Right column: control. Top row: proliferation (Ki-67). Bottom row: microvascular density (CD31). Note the significantly lower tumor proliferation (Ki-67) and tumor microvascular density (CD31) in the therapy compared to the control groupBack to article page
