Advanced Physics for Brachytherapy 2018

CT

Distortion evaluation

Results : There was no noteworthy difference with measurements done between 1.5T and 3T images, also inter and intra-observer, indicating a substantial agreement. Mean values for statistical analysis were calculated with a 95% confidence interval. There was no significant difference between axial and sagittal measurements. The maximum CT vs MRI deviation mean was 1.6mm ± 0.39 (SD).
