Development of ^𝟗𝟗𝐦𝐓𝐜-N4-NIM for Molecular Imaging of Tumor Hypoxia

Figure 4

Planar scintigraphy of ^99mTc-N4 and ^99mTc-N4-NIM (400 μCi/rat, iv, acquired 500,000 count) showed higher tumor-to-muscle count density ratio in ^99mTc-N4-NIM compared to that of ^99mTc-N4. The numbers are tumor-to-muscle count density ratios (counts/pixel) at 60–120 min.
