Filter by:This is a phase 1 study to determine the feasibility and utility of using serial magnetic resonance imaging (MRI) to assess treatment response during and after radiation therapy (standard of care cancer treatment) for participants with advanced esophageal cancer, glioblastoma, prostate cancer, vulvar cancer or pediatric glioma. The research study procedures include three MRI scans (one before, one during, and one after standard of care cancer radiation therapy) for participants with advanced esophageal cancer, glioblastoma, prostate cancer, vulvar cancer or pediatric glioma. The research study procedures include: - Screening for eligibility - Three MRI scans
This study aims to evaluate whether pre-treatment MRI can be used to predict treatment response for anti-angiogenic treatment in glioblastomas.
Aim of this study is to evaluate the correlation between the characteristics detected by the 7T MRI equipment and the histological composition of native explanted livers (group A), liver graft excluded for donation (group B) and surgical specimens of primary pancreatic tumour, which underwent pancreaticoduodenectomy (group C).
The Caroli disease is a very rare pathology that can be revealed early in childhood or in adulthood, whose diagnosis is based on Magnetic Resonance CholangioPancreatography, which shows the communication of these malformations with the rest of the biliary tree and allows to eliminate biliary stenosis. The radiologist has a central role in the diagnostic orientation between malformative intra-hepatic bile duct dilatation and obstructive benign or malignant intra-hepatic bile duct dilatation dilatation. However, imaging of Caroli disease is polymorphous and therefore subject to misinterpretation. The benefit of this research is to reduce diagnostic errors by highlighting imaging criteria specific to the Caroli disease
The purpose of this study is to establish a non-invasive radiomics method to filter high recurrent-risk liver transplantation recipient population
The overall goal of this study is to investigate the signal intensity and relaxation rate characteristics of gadoterate meglumine (Dotarem, Guerbet, USA) enhanced myocardium during rest and stress perfusion cardiovascular magnetic resonance (CMR) compared to gadobutrol (Gadavist) to prove that Dotarem provides constantly high myocardial relaxation necessary for accurate quantitative perfusion evaluation. The purpose of this study is to compare two types of contrast that patients receive during cardiac MRI scans to visualize the blood flow in the cardiac muscle. Both contrasts are used in standard of care procedures, and the one administered for each patient will be randomly selected. The length of the MRI study all procedures are the same as the clinically indicated scan.
This study is a diagnostic accuracy study that aims to evaluate the role of DTI in evaluation of DPN in comparison to clinical scores and nerve conduction studies (NCS). The study included 30 patients with diabetes mellitus complaining of neuropathy symptoms and 15 healthy volunteers. All subjects underwent evaluation using 1.5T DTI of median nerves and NCS. Patients underwent clinical evaluation using Neuropathy Deficit Score (NDS), Neuropathy Impairment Score in the Lower Limbs (NIS-LL) and Diabetic Neuropathy Examination (DNE) score. The values of these tests were compared and correlated and diagnostic accuracy tests were performed together with identification of cut-off score for abnormal diffusion tensor imaging parameters in diabetic neuropathy
This project will examine how virtual reality treatment that provides users with the alternate perspective of a virtual interpersonal interaction impacts psychological and neurobiological markers of social perspective taking in children with a disruptive behavior disorder. The investigators anticipate that experiencing a virtual encounter from a counterpart's point-of-view improves a child's perspective taking and alters brain function related to imagining another person's pain.
The goal of this clinical trial is to study the value and feasibility of magnetic resonance imaging in detection of bone marrow metastases
Despite the high prevalence of low back pain, little is still known about its underlying pathology. Only a small proportion of people (~1%) have a diagnosable pathoanatomical entity causing low back pain. The other types of back pain are classified as non-specific low back pain. Thus, current back pain management typically focuses on relieving symptoms. This is largely ineffective without understanding the cause. Yet, there are some pathologies which are thought to be associated with low back pain. Vertebral bone marrow oedemas are now known to be a hallmark feature for low back pain. There are three types of vertebral bone marrow oedemas. Type I oedemas are dynamic lesions that may progress to a higher grade, stop, or even return to normal. Although the precise cause of type I oedemas is not well understood, loading on the spine plays a key role in its development. Lumbar braces are known to reduce loads on the spine. Thus, they may reduce the size of oedema by modifying loads on the spine. The investigators already know that wearing a lumbar brace reduces pain in people with back pain and type I vertebral bone marrow oedemas. Unfortunately, there is no study showing that pain reduction with bracing is associated with a reduction of oedema. The goal of this study is to determine if wearing a lumbar brace for six weeks will reduce the dimensions of type I vertebral bone marrow oedema.
