Article Synopsis
  • MRI-only planning workflows have benefits but face image guidance challenges; this study explored using MRI for guiding treatment with Cone Beam Computed Tomography (CBCT).
  • Ten radiation therapists were trained and assessed on their ability to match MRI with CBCT across various anatomical regions, using data from multiple patients.
  • Results showed minimal differences in matching accuracy based on therapists' experience, indicating that focused training can effectively integrate MRI to CBCT guidance in clinical practice.

Article Synopsis
  • Researchers aimed to validate a hybrid method for creating synthetic computed tomography (sCT) from MRI scans, focusing on both male and female patients with pelvic cancers, as prior studies were mostly limited to male anatomy.
  • They analyzed data from 40 patients (20 males and 20 females) using a multi-atlas local weighted voting method to generate sCT images and compared dosimetric outcomes against traditional CT scans.
  • Results showed high agreement between treatment plans on CT and sCT, with similar dose differences and gamma agreement scores for both genders, indicating that MRI-only treatment planning is feasible for pelvic malignancies in both males and females.

Introduction: Adaptive communication is an essential requirement to deliver quality patient-centred care. Determining patients' informational needs and acting on the needs are skills radiation therapists (RTs) employ daily with patients. Learning health literacy (HL) strategies to assist with the informational delivery provides RTs with options to improve patients' understanding of vital radiotherapy treatment information or tasks.

Purpose: There are several means of synthetic computed tomography (sCT) generation for magnetic resonance imaging (MRI)-only planning; however, much of the research omits large pelvic treatment regions and female anatomical specific methods. This research aimed to apply four of the most popular methods of sCT creation to facilitate MRI-only radiotherapy treatment planning for male and female anorectal and gynecological neoplasms. sCT methods were validated against conventional computed tomography (CT), with regard to Hounsfield unit (HU) estimation and plan dosimetry.

Background And Purpose: Magnetic resonance imaging (MRI)-only treatment planning is gaining in popularity in radiation oncology, with various methods available to generate a synthetic computed tomography (sCT) for this purpose. The aim of this study was to validate a sCT generation software for MRI-only radiotherapy planning of male and female pelvic cancers. The secondary aim of this study was to improve dose agreement by applying a derived relative electron and mass density (RED) curve to the sCT.
