Figure 4
Synchrotron computed tomography. Ten consecutive CT images (slice thickness: 1 mm) of the rat head of two representative animals. (a) Untreated animal, imaged 18 days after tumor implantation, survival time 21 days; the tumor is clearly visible on six slices with a tumor volume index of ∼180 mm3. (b) Group `IUdR alone'; imaged on day 17 after tumor implantation; survival time 51 days. The tumor was no longer detectable after IUdR infusion over six days (b), even with an optimized grey level windowing. |
