18F-FLUC PET/MR in Patients With Brain Mets
The goal of this clinical trial is to use new imaging methods to help in finding out whether the imaging shows that there is a tumor in people with a brain metastasis. The main question it aims to answer is whether positron emission tomography (PET) and magnetic resonance imaging (MRI) …
MR-guided Prostate Stereotactic Body Radiotherapy in Seven Days
The Proseven trial is a prospective interventional study that will evaluate the toxicity and efficacy of MR-guided stereotactic body radiotherapy (SBRT) in the profound hypofractionated treatment of prostate cancer. Patients will be treated in 5 daily fractions within a short overall treatment time (OTT) of 7 days. A simultaneous integrated …
MR-informed Stereotactic Radiotherapy for Treatment of Ultracentral Lung Tumours Utilising a Dedicated MR-simulator for Daily Adaptation Followed by CBCT-guided Treatment Delivery
Stereotactic body radiotherapy (SBRT) is the preferred treatment for inoperable early-stage non-small cell lung cancer (NSCLC) and for operable cases when patients decline surgery, offering local control (LC) rates of 80-97%. SBRT is also used in oligometastatic cancer. However, its safety and efficacy for ultra-central lung tumours, near the proximal …
PET/MR Pre- and Post Radiotherapy for Cardiopulmonary Dysfunction Evaluation
Radiotherapy (RT) is a well-known and established therapy or adjuvant therapy for the treatment of thoracic cancer It uses a high energy radiation from x-rays, gamma rays and other charged particles that assist in damaging the cancer DNA. PET/MR as imaging biomarkers for cardiopulmonary dysfunction with a focus on Pulmonary …
Northern Alberta Linac-MR Image-Guided Radiotherapy (Northern LIGHTs-2)
Cancers are often treated with external beam radiotherapy. Current radiotherapy treatments are performed using computed tomography (also known as CT) scans which may not always clearly identify the cancer. In some instances, magnetic resonance imaging (MRI) may be able to better identify cancers. Therefore, efforts are currently underway to use …
Dose Escalated Radiotherapy for Rectal Cancers Using MR-guided Radiotherapy
Standard radiotherapy in the UK involves having daily chemotherapy tablets with radiotherapy treatment for 5 weeks at a dose of 52.5Gy to the rectal cancer over 25 fractions. This is the likely treatment participants will be having if they decide not to take part in this study. Increasing the dose …
Use of Hyperpolarized 129Xe MR Lung Imaging in Adults for Calibration
The goal of this study is to evaluate the usefulness of hyperpolarized (HP) 129Xe (xenon) gas MRI for regional assessment of lung function in a normal population of adults for the purposes of obtaining optimal images through MRI.
Cardiovascular Manifestations of MR Activation in Primary Aldosteronism: Pilot Clinical Study
This research study aims to learn more about the impact the hormone aldosterone on the heart. Primary aldosteronism is a condition where the body's adrenal glands make too much of the hormone aldosterone, which can cause high blood pressure and increase the risk of heart and kidney disease. Treatment with …
Hyperpolarized MR Imaging with Carbon-13 Pyruvate in the Human Body
Positron emission tomography with 18F fluorodeoxyglucose (FDG) is the conventional imaging technique to provide information regarding tissue glucose uptake and has been highly clinically successful. However, it cannot assess downstream metabolism, which may be useful in the diagnosis and assessment of treatment response in a variety of diseases. Patients will …
MR-Guided Radiotherapy Dose Escalation Trial for Esophageal Squamous Cell Carcinoma
SUMMARY Rationale: Esophageal cancer (EC) is the seventh most frequently diagnosed cancer and the sixth leading cause of cancer-related death worldwide. As a result of the late onset of symptoms, most patients with EC present in an advanced stage with a corresponding poor prognosis. Poor disease outcome after surgery alone …
