DE-MR simulation imaging for prone radiotherapy after breast-conserving surgery: assessing its application in lumpectomy cavity delineation based on deformable image registration |pdf=|usr=}}{{34001182}} gab.com Text DE-MR simulation imaging for prone radiotherapy after breast-conserving surgery: assessing its application in lumpectomy cavity delineation based on deformable image registration JO: Radiat Oncol http://www.kidney.de/pget.php?&tw=1&pmid=34001182 #FOAvip BACKGROUND: The application of delayed-enhancement magnetic resonance (DE-MR) simulation imaging in lumpectomy cavity (LC) delineation for prone radiotherapy in patients with an invisible seroma or a low seroma clarity score (SCS) after breast-conserving surgery (BCS) based on deformable image registration (DIR) was assessed. METHODS: Twenty-six patients who were suitable for radiotherapy in prone positions after BCS were enrolled, and both computed tomography (CT) and DE-MR simulation scans were acquired. The LC delineated based on titanium surgical clips on CT images was denoted as LC(CT). The LC delineated based on the signal of cavity boundaries on fat-suppressed T2-weighted imaging (T2WI) and multiphase delayed-enhancement T1-weighted imaging (DE-T1WI), which was performed at 2 min, 5 min and 10 min postinjection, were denoted as LC(T2), LC(2T1), LC(5T1) and LC(10T1), respectively. Afterwards, DIR was performed to compare the volumes and locations of the LCs with MIM software. The generalized conformity index (CIgen) of inter (intra) observer (Inter-CIgen and Intra-CIgen) was also used to explore the inter(intra) observer variation for LC delineation on each image modality. RESULTS: LC(CT)-LC(10T1) provided the best conformal index (CI) and degree of inclusion (DI), increasing by 2.08% and 4.48% compared to LC(CT)-LC(T2), 11.36% and 2.94% for LC(CT)-LC(2T1), and 8.89% and 7.69% for LC(5T1)-LC(CT), respectively. The center of mass (COM) of LC(CT)-LC(10T1) decreased by 17.86%, 6.12% and 13.21% compared with that of LC(CT)-LC(T2), LC(CT)-LC(2T1) and LC(CT)-LC(5T1), respectively. The agreement of LC delineation was strongest for 10th min DE-TIWI (coefficient of variation, COV = 2.30%, Inter-CIgen = 87.06%, Intra-CIgen = 92.64%). CONCLUSION: For patients with a low SCS (SCS </= 2) after BCS, it is feasible to contour the LC based on prone DE-MR simulation images. Furthermore, the LC derived from prone DE-T1WI at 10 min was found to be most similar to that derived from prone CT simulation scans using titanium surgical clips regardless of the volume and location of the LC. Inter (intra) variability was minimal for the delineation of the LC based on 10th min DE-TIWI.
