There was no correlation in the latter scan between the [18F]EF5 uptake and the tumor volume (r = −0.217, p = 0.55).
There was a clear correlation between the percentage of tumor growth rate per day and the [18F]EF5 uptake in the latter scan (r = 0.766, p = 0.01).
Instead, the uptake of [18F]EF5 in the latter scan showed a stronger correlation with the tumor growth rate (r = 0.766) which was statistically significant (p = 0.01) (Figure 3).
The uptake of [18F]EF5 in the latter scan did not correlate with the tumor size (r = −0.217) in our study population.
Both measured tumors were found to be hypoxic, and the [18F]EF5 uptake values of the latter scan in these tumors were higher than the corresponding median [18F]EF5 uptake value (Table 2).
Due to its lower uptake, the latter scan should be more challenging for the motion correction process.
Nevertheless, at the latter [18F]EF5 scan, tumors were larger, and hence, the risk of biases introduced by the partial volume effect is not considered to affect these findings.
There was only a weak positive correlation (r = 0.398) between the [18F]EF5 uptake of the first scan and the tumor growth rate, in contrast to the clear correlation (r = 0.766) noted between the latter [18F]EF5 scan which was performed during the late phase of exponential growth.
For the album's singles, Martin asked Sundsbø what he could do; the latter suggested scanning the head of each member of the band (Sundsbø also did artwork duties for the Live 2003 home video).
