Quantifying setup uncertainty between computed tomography guidance and magnetic resonance guidance in intramuscular metastases radiotherapy
Puntos clave
The aim is to quantify the dosimetric differences in radiotherapy for intramuscular metastases when using MR guidance compared to CT guidance.
Compared dosimetric outcomes between MRgRT and CTgRT in treating intramuscular metastases.
Measured treatment margins for both modalities.
MRgRT allows for a reduction of treatment margin by at least 5 mm in each direction.
Dosimetric advantages of MRgRT are highlighted compared to CTgRT.
Resumen
We quantified the dosimetric difference in treating intramuscular metastases using MRgRT versus CTgRT and showed that treatment margin can be reduced by at least 5 mm in each direction with MRgRT.
