Figure 4. Detection of 1–2 pixel RenCa lung metastases.

Figure 4

A-Three lung nodules are identified on the post contrast scL-gad-d images. The two smaller nodules (N1 and N2) measure 1–2 pixels (approximately 100–200 microns) in size. They measure about 700 microns apart. They are just barely visible on the pre-contrast images. The Arrows indicate the lung nodules.
