MR-Guided Adaptive Radiotherapy for Bladder Cancer [PDF]

Frontiers in Oncology, 2021
Radiotherapy has an important role in the curative and palliative treatment settings for bladder cancer. As a target for radiotherapy the bladder presents a number of technical challenges.

Preliminary study of cine-MRI compression in MR-guided radiotherapy. [PDF]

Quant Imaging Med Surg, 2023
Cine-magnetic resonance imaging (MRI) is currently used in real-time tumor tracking during magnetic resonance (MR)-guided radiotherapy. As a type of MRI specified for motion tracking, a few minutes' acquisition results in thousands of 2-dimensional (2D) images.

MR-guided radiotherapy of moving targets [PDF]

Der Radiologe, 2021
Hybrid magnetic resonance (MR) linear accelerators (MR-Linacs) for radiotherapy allow for the visualization and tracking of moving target volumes during the entire treatment. This makes gated treatments possible, decreasing the irradiated volumes and thus sparing healthy tissue from unnecessary radiation dose. Conventionally, tumors that are subject to

Review of MR-Guided Radiotherapy for Esophageal Cancer. [PDF]

Front Oncol, 2021
In this review, we outline the potential benefits and the future role of MRI and MR-guided radiotherapy (MRgRT) in the management of esophageal cancer. Although not currently used in most clinical practice settings, MRI is a useful non-invasive imaging modality that provides excellent soft tissue contrast and the ability to visualize cancer physiology.

MR-Guided Radiotherapy for Brain and Spine Tumors. [PDF]

Front Oncol, 2021
MRI is the standard modality to assess anatomy and response to treatment in brain and spine tumors given its superb anatomic soft tissue contrast (e.g., T1 and T2) and numerous additional intrinsic contrast mechanisms that can be used to investigate physiology (e.g., diffusion, perfusion, spectroscopy). As such, hybrid MRI and radiotherapy (RT) devices

Medical physics challenges in clinical MR-guided radiotherapy. [PDF]

Radiat Oncol, 2020
AbstractThe integration of magnetic resonance imaging (MRI) for guidance in external beam radiotherapy has faced significant research and development efforts in recent years. The current availability of linear accelerators with an embedded MRI unit, providing volumetric imaging at excellent soft tissue contrast, is expected to provide novel ...

Leaf-individual calibration for a double stack multileaf collimator in photon radiotherapy

Physics and Imaging in Radiation Oncology, 2023
Background and Purpose: In online adaptive stereotactic body radiotherapy treatments, linear accelerator delivery accuracy is essential. Recently introduced double stack multileaf collimators (MLCs) have new facets in their calibration.

MR-CBCT image-guided system for radiotherapy of orthotopic rat prostate tumors. [PDF]

PLoS ONE, 2018
Multi-modality image-guided radiotherapy is the standard of care in contemporary cancer management; however, it is not common in preclinical settings due to both hardware and software limitations.

Feasibility of tumour-focused adaptive radiotherapy for bladder cancer on the MR-linac

Clinical and Translational Radiation Oncology, 2022
Bladder tumour-focused magnetic resonance image-guided adaptive radiotherapy using a 1.5 Tesla MR-linac is feasible. A full online workflow adapting to anatomy at each fraction is achievable in approximately 30 min. Intra-fraction bladder filling did not

Stereotactic MR-Guided Radiotherapy for Adrenal Gland Metastases: First Clinical Results. [PDF]

J Clin Med, 2022
Stereotactic MR-guided Radiotherapy (MRgRT) is an interesting treatment option for adrenal gland metastases (AGM). We reviewed data from 12 consecutive patients treated with MRgRT for an AGM in our center between 14 November 2019 and 17 August 2021.
