Table 3.
Number of patients in relation to the total number of evaluated patients where TTP derived from ROI and VOI analysis of PET data changed following MR-AC as compared to CT-AC
AC method | ROI90 | VOI90 | ROITBR | VOITBR | VOIFix |
---|---|---|---|---|---|
Dixon | 2/24 (1, 2) | 0/23 | 3/24 (1, 1, 3) | 1/17 (1) | 1/24 (1) |
UTE | 2/24 (1, 3) | 4/23 (1, 1, 1, 1) | 3/24 (1, 1, 1) | 1/17 (2) | 2/14 (1, 1) |
Model-based | 2/24 (1, 1) | 1/23 (1) | 4/24 (1, 2, 3, 6) | 2/17 (2, 6) | 2/24 (1, 1) |
The numbers in brackets are the ΔTTP in units of time frames for the cases where TTP changed (e.g. (1,3) means TTP shifted one time frame in one case and three time frames in another)
