Abstract EN
Accurate lumpectomy cavity definition is critical in breast treatment planning.
We compared contouring lumpectomy cavity volume and cavity visualization score (CVS) with CT versus 3T MRI.
29 patients were imaged with CT and 3T MRI.
Seven additional boost planning sets were obtained for 36 image sets total.
Three observers contoured the lumpectomy cavity on all images, assigning a cavity visualization score (CVS ) of 1 to 5.
Measures of consistency and agreement for CT volumes were 98.84% and 98.62%, for T1 MRI were 95.65% and 95.55%, and for T2 MRI were 97.63% and 97.71%.
The mean CT, T1 MRI, and T2 MRI CVS scores were 3.28, 3.38, and 4.32, respectively.
There was a highly significant difference between CT and T2 scores (P<.00001) and between T1 and T2 scores (P<.00001).
Interobserver consistency and agreement regarding volumes were high for all three modalities with T2 MRI CVS the highest.
MRI may contribute to target definition in selected patients.
