Automatic contouring of soft organs for image-guided prostate radiotherapy
Automatic contouring of soft organs for image-guided prostate radiotherapy
Results: MRI delineation reduced intra-observer variability compared to pCT. DIR-whole resulted in GTVs significantly closer to the GS as determined by multiple positional metrics in comparison with CT-only delineation (normalised results are shown in Figure 1). The mean Dice Similarity Coefficient was 0.6 and 0.72 for pCT and DIR-whole respectively with p= 0.019. Use of MRI-D with Rigid-ROI or DIR-ROI provided no advantage over CT-only delineation.
Conclusion: In the absence of dedicated MRI-RT, image registration software can aid the integration of MRI-D into the treatment pathway. MRI-D is most accurately integrated into the radiotherapy planning pathway when contours are transposed to pCT with DIR over the whole patient.

Abstract
Results: MRI delineation reduced intra-observer variability compared to pCT. DIR-whole resulted in GTVs significantly closer to the GS as determined by multiple positional metrics in comparison with CT-only delineation (normalised results are shown in Figure 1). The mean Dice Similarity Coefficient was 0.6 and 0.72 for pCT and DIR-whole respectively with p= 0.019. Use of MRI-D with Rigid-ROI or DIR-ROI provided no advantage over CT-only delineation.
Conclusion: In the absence of dedicated MRI-RT, image registration software can aid the integration of MRI-D into the treatment pathway. MRI-D is most accurately integrated into the radiotherapy planning pathway when contours are transposed to pCT with DIR over the whole patient.
