The aim of this systematic review and meta\u2010analysis was to compare the dose parameters and long\u2010term effects of MRI\u2010based, CT\u2010based and hybrid imaging (MRI\/CT)\u2010based volumetric planning. A systematic search was conducted to identify the clinical studies of BT treatment on cervical cancer patients. After study selection, a total of 13 clinical studies were enrolled for further analysis. No obvious differences were observed among the treatment parameters and the patients included. In detail, no significant difference was observed among these three techniques of volumetric planning in the parameters of high\u2010risk clinical target volume (HR\u2010CTV), total dose of D90 or mean fraction dose of D90. Meanwhile, MRI\u2010based planning was superior to CT\u2010based treatment in the total dose D2cc to organs at risk (OAR) for the bladder, rectum and sigmoid. Furthermore, no significant difference was observed among MRI\u2010, CT\u2010 or hybrid\u2010based treatments with the mean fraction dose D2cc to OAR for the bladder, rectum or sigmoid. In conclusion, MRI provides good anatomical delineation of the relevant HR\u2010CTV and OAR, and performed better in the analyses of dose parameters compared with CT. At least one MR image is required to assess the tumour extension, with clinical findings and MRI information facilitating much more accurate CT\u2010based contouring.<\/jats:p>","DOI":"10.1111\/1754-9485.12984","type":"journal-article","created":{"date-parts":[[2019,12,17]],"date-time":"2019-12-17T08:48:20Z","timestamp":1576572500000},"page":"151-162","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Comparison
