Filter by:Participants with known or suspected hydrocephalus will receive brain scans using the Hyperfine, low field strength, portable, magnetic resonance imaging (MRI) system in addition to their scheduled outpatient standard of care clinical computed tomography (CT) or MRI scan. The purpose of this pilot study is to evaluate the feasibility and acceptability of using the Hyperfine system in an outpatient setting and to compare its diagnostic performance to standard clinical imaging. Outpatients with other known or suspected neurological disorders or conditions prompting routine clinical brain imaging with MRI or CT will also be enrolled and the diagnostic performance of low field scans compared to that of the same day standard of care clinical imaging.
The study involves the development and testing of an artificial intelligence (AI) tool that can identify abnormalities using patient head scans conducted for routine clinical care and research volunteer scans. A deep learning algorithm will be developed using a dataset of retrospective and prospective MRI head scans to train, validate, and test convolutional networks using software developed at the Department of Biomedical Engineering, King's College London. The reference standard will be consultant radiologist reports of the MRI head scans.
The study is designed to collect data that will aid in future scientific and engineering exploration of correlations between clinical assessments and BNA scores. The results are primarily intended for scientific inquiry and engineering development purposes, and may be used in future regulatory submissions.
The purpose of this study is to investigate the effects of training of the non-involved upper limb on the motor ability of the hemiparetic upper limb in patients with unilateral sensorimotor motor impairments. The secondary aims are to investigate the relation between lesion characteristics and responsiveness to the treatment, and to study which brain structures are activated during a task trained in the treatment.
Background: - Many psychiatric, behavioral, and developmental disorders are genetic. This means that they tend to run in families. Some begin in childhood, while others do not appear until adulthood. Researchers want to look at people of all ages who have these disorders that started in childhood. They will also look at relatives of people with these disorders. This information will allow doctors to learn more about childhood behavioral problems and how they are inherited. It may also help doctors treat those disorders. Objectives: - To study the onset and treatment of childhood behavioral, psychiatric, and developmental disorders. Eligibility: - Individuals of any age who have a psychiatric, autism spectrum, or developmental disorder, or other behavioral problems. - Family members of individuals with the above disorders. This group may include parents, grandparents, siblings, aunts/uncles, cousins, and children. Design: - Participants will be screened with a medical history and physical exam. They will have a psychiatric history with tests of thinking, judgment, and behavior. Blood and urine samples will be collected. Brain imaging scans will be performed to look at brain function. They may have a spinal tap to collect cerebrospinal fluid. - Relatives will have a medical history and physical exam. They will also have a psychiatric history with tests of thinking, judgment, and behavior. Blood and urine samples will be collected. Brain imaging scans will be performed to look at brain function. - A relative s exams may reveal a behavioral or other disorder. If so, he or she may re-enroll on the study as a person with the disorder.
