Dosimetric and Deformation Effects of Image-Guided Interventions during Stereotactic Body Radiation Therapy of the Prostate using an Endorectal Balloon

, 2012
During Stereotactic Body Radiotherapy (SBRT) for the treatment of prostate cancer, an inflatable endorectal balloon (ERB) may be used to reduce motion of the target and reduce the dose to the posterior rectal wall.

A Comparative Study of IVIM‐MRI Fitting Techniques in Glioma Grading: Conventional, Bayesian, and Voxel‐Wise and Spatially‐Aware Deep Learning Approaches

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Intravoxel incoherent motion (IVIM) analysis of diffusion‐weighted MRI (DWI) provides microvascular perfusion and diffusion information. However, parameter estimation is limited by noise sensitivity, variability across fitting methods, and lack of standardization.

An efficient and robust MRI-guided radiotherapy planning approach for targeting abdominal organs and tumours in the mouse.

PLoS ONE, 2017
IntroductionPreclinical CT-guided radiotherapy platforms are increasingly used but the CT images are characterized by poor soft tissue contrast. The aim of this study was to develop a robust and accurate method of MRI-guided radiotherapy (MR-IGRT ...

MRI for Lung Cancer Management: Any Closer to Clinical Application?

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Management of lung cancer (LC) encompasses screening, diagnosis, staging, radiotherapy planning and guidance, therapy monitoring and surveillance. Across these domains, magnetic resonance imaging (MRI) offers a range of morphological and functional imaging capabilities—including diffusion‐weighted imaging (DWI), dynamic contrast‐enhanced (DCE)

Stabilised Hyaluronic Acid Gel Rectal Spacers in MRI‐Guided Brachytherapy for Gynaecological Cancers: A Prospective Feasibility Study

Journal of Medical Radiation Sciences, EarlyView.
This prospective study investigated the feasibility of stabilised hyaluronic acid gel as a rectal spacer in gynaecological cancer brachytherapy. In twelve patients, the spacer was successfully inserted into the rectovaginal space without serious adverse events, had high visibility on MRI, increased the target‐to‐rectum distance compared with no spacer ...

The impact of rectal spacers in MR-guided adaptive radiotherapy

Clinical and Translational Radiation Oncology
The use of stereotactic ablative radiotherapy (SABR) for prostate cancer has increased significantly. However, SABR can elevate the risk of moderate gastrointestinal (GI) side effects. Rectal spacers mitigate this risk by reducing the rectal dose. This study evaluates the impact of rectal spacers in MR-guided adaptive radiotherapy (MRgART) for prostate

Optimising hypoxia PET imaging and its applications in guiding targeted radiation therapy for non‐small cell lung cancer: a scoping review

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 106-118, March 2025.
This review article reports that quantification of hypoxic volumes using PET in the pre‐radiation therapy setting is of prognostic value and indicative of treatment response in non‐small cell lung cancer. Abstract Introduction Non‐small cell lung cancer (NSCLC) is the leading cause of cancer‐related death. Definitive treatment includes chemotherapy and
