The comparison of high-risk clinical target volumes between computed tomography and magnetic resonance imaging in cervical cancer
Purpose: This study was carried out to compare the volume and dose of target volumes, as well as organs at risk (OARs), between CT and MRI in intracavitary brachytherapy. Materials and methods: Retrospective data from the MRI and CT imaging of the first application of 15 patients with locally advanc...

| Summary: | Purpose: This study was carried out to compare the volume and dose of target volumes, as well as organs at risk (OARs), between CT and MRI in intracavitary brachytherapy. Materials and methods: Retrospective data from the MRI and CT imaging of the first application of 15 patients with locally advanced carcinoma of cervix uteri were collected and evaluated in terms of volume-based concepts. The volume and D90 of HR-CTV of MRI was compared with the CT while the volume and D2cc of organs at risk (bladder, and sigmoid colon) were compared as well with the concepts of the Groupe Européen de Curiethérapie - European Society for Therapeutic Radiology and Oncology (GEC-ESTRO). Results: No statistical significance between the MRI and CT of HR-CTV, bladder and sigmoid colon was observed. Conclusion: The volumes of HR-CTV of MRI versus CT were not statistically significant although the MRI yielded good tumour identification. © 2013 Biomedical Imaging and Intervention Journal.
