Filter by:The aim of this study is to evaluate the indications and therapeutical consequences of MRI scans of (young) children undergoing risky remote anaesthesia. The investigators want to aim for a clear indication in children undergoing MRI in the future before undergoing possible unnecessary procedures and MRI scans.
The diagnostic pathway for suspected prostate cancer relies greatly on radiological imaging. Establishment of magnetic resonance fingerprinting (MRF) has the potential to significantly improve patient experience and outcomes. MRF is a novel and innovative approach to a long-standing challenge of recording and reconstructing MR image The aim is to conduct a clinical pilot study in which patients will be scanned using the newly refined MRF sequence in addition to the conventional scanning protocols.
This study aims to compare image qualities between conventionally reconstructed MRI sequences and deep-learning reconstructed MRI sequences from the same data in patients who undergo Gd-EOB-DTPA enhanced liver MRI. The AIRTM deep learning sequence is applicable for various MRI sequences including T2-weighted image (T2WI), T1-weighted image and diffusion-weighted image (DWI). We plan to perform intra-individual comparisons of the image qualities between two reconstructed image datasets.
Magnetic resonance imaging (MRI) is a diagnostic tool in medicine that generates high quality images of the human body without the use of x-rays. Volunteers will be asked to participate in a study to evaluate improved MRI hardware that can be used to enhance the ability of MRI as a diagnostic tool. Specifically, this hardware is designed to acquire high quality images of the brain. This MRI hardware will eventually be integrated into a positron emission tomography (PET) system, which will be able to detect trace amounts of brain disease and/or brain function simultaneously with MRI. The combined system is known as a PET/MRI. For the purposes of this test, the investigators are just evaluating the MRI hardware, which will be installed in a plastic mockup of the PET system.
This multi-site study will examine patients with epilepsy (ES) following head injury [i.e., posttraumatic epilepsy (PTE)] and posttraumatic psychogenic Non-epileptic seizures (PNES) and will compare them to patients with traumatic brain injury (TBI) who do not have seizures using functional neuroimaging.
Primary sclerosing cholangitis (PSC) is a chronic liver disease that can lead to liver cirrhosis, liver failure and liver cancer. Assessment of disease status is important to determine optimal treatment but the diagnosis of PSC is challenging. There is a dire need of an accurate non-invasive tool for longitudinal assessment of PSC. MR Elastography (MRE) has been recently proven to estimate liver fibrosis noninvasively and accurately. Estimation of liver fibrosis by MRE along with imaging derived morphological information (MRCP) will be utilized in this study comprehensively to provide a surrogate non-invasive imaging biomarker for monitoring disease status in PSC. Successful outcomes will provide an opportunity for optimal treatment triage including liver transplantation via accurate and non-invasive estimation of true disease status in PSC.
The application of FCH PET in breast cancer diagnosis has not been reported. We hypothesize that FCH reveals choline metabolic profiles of breast cancers, and shows the similar pathophysiological mechanism to choline on proton MRS, and our study goals are: 1. To investigate and compare the diagnostic performance of proton MRS and FCH PET for localized findings on mammography and breast ultrasound. 2. To investigate whether FCH PET findings are correlated with choline signals on proton MRS. 3. To evaluate if choline, water and lipid signals on proton MRS, FCH PET are associated with factors related to clinical outcome and prognosis- that is, molecular markers, tumor staging, histologic grade of breast cancers. 4. For localized advanced breast cancer, to investigate the treatment response to NAC using proton MRS and FCH PET, and to evaluate which modality is more sensitive. 5. To investigate the usefulness of FCH PET for whole body staging for breast cancer patients.
