Background: Magnetic resonance imaging (MRI) is a tool for getting pictures of the tissues and organs inside the body. MRI can help diagnose many injuries and diseases. But not all patients are equally likely to receive MRIs. Factors such as race or ethnicity, distance to imaging centers, mobility, and a lower income can limit some people s access to MRIs. A new ultra-low field (ULF) type of MRI, which can be used on a vehicle, may help take imaging scans to more people. But researchers need to know that UFL-MRI works just as well as standard MRIs. Objective: To learn whether UFL-MRI is as good as standard MRI at detecting neurological disorders. Eligibility: People aged 3 years or older who have or show symptoms of neurological disease (such as stroke, cancer, or epilepsy). Healthy adults are also needed. Design: Participants will have 1 or 2 study visits. Adult participants will have a physical exam. They will receive two MRI exams: - Standard MRI. They will lie still on a narrow bed that will move into a large tube. They will wear earplugs to muffle the sounds. - ULF-MRI. They will lie on a stretcher, and only their head will be inside a smaller tube. The noises will be quieter. They will wear earplugs to muffle the sounds. Some adults may receive a contrast agent given through a small tube attached to a needle in the arm. The contrast agent helps the researchers see differences in the body more clearly. This may be done during 1 or both MRIs. Children will have only 1 ULF-MRI. Some participants may be invited to have additional visits for up to 6 months.

Background: - Malignant mesothelioma is a malignancy arising from the mesothelial cells of the pleura, peritoneum, pericardium, or tunica vaginalis. - Mesothelioma accounts for 0.10% of deaths annually in the United States. Malignant pleural mesothelioma is the most common of these, comprising of 80% of the cases with an annual incidence of about 2,500 in the United States. - The median survival from diagnosis of pleural mesothelioma is approximately 12 months. The majority of patients present with stage III or IV disease with 85-90% of patients considered unresectable at diagnosis. - Peritoneal mesothelioma has a better prognosis than pleural mesothelioma; nevertheless, patients undergoing therapy for peritoneal mesothelioma have few well-studied treatment options due in large part to the rarity of the disease. - In addition to mesothelioma, mesothelin is highly expressed in several cancers, including pancreatic, biliary adenocarcinomas, gastric and ovarian cancers; mesothelin is also expressed in a significantly larger proportion of thymic carcinoma than thymoma. Objectives: -To allow sample acquisition for use in the study of mesothelioma. Eligibility: - All participants age greater than or equal to 2 years with malignant mesothelioma OR - All participants greater than or equal to 18 years with thymic carcinoma, pancreatic or biliary adenocarcinoma or lung, gastric or ovarian cancers or other solid tumor known to express mesothelin - Must be able and willing to provide informed consent if 18 or over; parent or guardian must be able and willing to provide consent for patients under the age of 18 Design: - Up to 1000 subjects will be enrolled. - Patients will be followed to determine the course of disease and to record any treatment received for mesothelioma. - Patients will undergo sampling of blood, urine, tumor and abnormal body fluids for tissue banking. - Studies which may be performed on banked material include genetic and genomic studies, establishment of cell cultures and immunologic studies.

Background: - Stem cell transplants from related donors (allogenic stem cell transplants) can be used to treat individuals with certain kinds of severe blood diseases or cancers, such as severe anemia. Allogenic stem cell transplants encourage the growth of new bone marrow to replace that of the recipient. Because stem cell transplants can have serious complications, researchers are interested in developing new approaches to stem cell transplants that will reduce the likelihood of these complications. - By reducing the number of white blood cells included in the blood taken during the stem cell collection process, and replacing them with a smaller amount of white blood cells collected prior to stem cell donation, the stem cell transplant may be less likely to cause severe complications for the recipient. Researchers are investigating whether altering the stem cell transplant donation procedure in this manner will improve the likelihood of a successful stem cell transplant with fewer complications. Objectives: - To evaluate a new method of stem cell transplantation that may reduce the possibly of severe side effects or transplant rejection in the recipient. Eligibility: - Recipient: Individuals between 4 and 80 years of age who have been diagnosed with a blood disease that can be treated with allogenic stem cell transplants. - Donor: Individuals between 4 and 80 years of age who are related to the recipient and are eligible to donate blood. OR unrelated donors found through the National Marrow Donor Program. Design: - All participants will be screened with a physical examination and medical history. - DONORS: - Donors will undergo an initial apheresis procedure to donate white blood cells. - After the initial donation, donors will receive injections of filgrastim to release bone marrow cells into the blood. - After 5 days of filgrastim injections, donors will have apheresis again to donate stem cells that are present in the blood. - RECIPIENTS: - Recipients will provide an initial donation of white blood cells to be used for research purposes only. - From 7 days before the stem cell transplant, participants will be admitted to the inpatient unit of the National Institutes of Health Clinical Center and will receive regular doses of cyclophosphamide, fludarabine, and anti-thymocyte globulin to suppress their immune system and prepare for the transplant. - After the initial chemotherapy, participants will receive the donated white blood cells and stem cells as a single infusion. - After the stem cell and white blood cell transplant, participants will have regular doses of cyclosporine and methotrexate to prevent rejection of the donor cells. Participants will have three doses of methotrexate within the week after the transplant, but will continue to take cyclosporine for up to 4 months after the transplant. - Participants will remain in inpatient care for up to 1 month after the transplant, and will be followed with regular visits for up to 3 years with periodic visits thereafter to evaluate the success of the transplant and any side effects.

Background: Multiple myeloma (MM) is an incurable cancer of certain blood cells. MM often returns after treatment, and most people survive only 5 to 8 years after diagnosis. To improve survival, researchers need to find ways to identify returning disease earlier. Objective: To find out if the radiotracer 18F-fluciclovine (a substance injected into the blood during imaging scans) is better at detecting MM than the one (18F-FDG) currently used for this purpose. Eligibility: Adults aged 18 years or older with MM. The MM may be newly diagnosed (NDMM); or it may have returned or failed to respond after at least 1 prior line of treatment (RRMM). Design: Participants will be screened. They will have blood tests. They will have a positron emission tomography (PET) or computed tomography (CT) scan using 18F-FDG. The radiotracer will be injected into a vein. Then participants will lie on a table while the PET/CT scan takes images of their body. All participants will have 3 study visits. During each visit they will have: Two PET/CT scans. One with 18F-FDG, one with 18F-fluciclovine. An optional magnetic resonance imaging scan. A bone marrow biopsy. An area on the hip will be numbed; a needle will be inserted to draw out a sample of the soft tissue from inside the bone. These tests may be spread over 30 days for each visit. NDMM participants will have their second study visit 2 to 4 weeks after they complete their usual treatment for the disease. RRMM participants will have their second visit 6 months after their first.

Background: Chronic lymphocytic leukemia (CLL),small lymphocytic lymphoma (SLL) and B-cell acute lymphoblastic leukemia or lymphoma (ALL) are blood cancers that affect certain white blood cells. Advanced forms of these diseases are difficult to treat. CD19 is a protein often found on the surfaces of these cancer cells. Researchers can modify a person's own immune cells (T cells) to target CD19. When these modified T cells are returned to the body-a treatment called anti-CD19 chimeric antigen receptor (CAR) T cell therapy-they may help kill cancer cells. Objective: To test anti-CD19 CAR T cell therapy in people with CLL or SLL and ALL. Eligibility: People aged 18 years and older with CLL or SLL and ALL that has not been controlled with standard drugs. Design: Participants will be screened. They will have imaging scans and tests of their heart function. If a sample of tissue from their tumor is not available, a new one may be taken; the sample will be tested for CD19. Participants will receive a drug to reduce the leukemia cells in their blood. Then they will undergo apheresis: Blood will be taken from the body through a needle. The blood will pass through a machine that separates out the T cells. The remaining blood will be returned to the body through a different needle. The collected T cells will be gene edited to make them attack cells with CD19. Participants will take drugs to prepare them for treatment for 3 days. These drugs will start 5 days before the treatment. Then their own modified CAR T cells will be returned to their bloodstream. Participants will stay in the hospital for at least 9 days after the treatment. Follow-up visits will continue for 5 years.

Background: Runt-related transcription factor 1 (RUNX1) gene regulates the formation of blood cells. People with mutations of this gene may bleed or bruise easily; they are also at higher risk of getting cancers of the blood, bone marrow, and lymph nodes. Objective: The purpose of the study includes determining which dose of imatinib is best for people with pathogenic or likely pathogenic RUNX1 mutations without blood cancers, and to determine whether there are any changes in platelet function and inflammatory markers. Eligibility: Adults aged 18 and older with RUNX1 mutations. Healthy people without this mutation, including family members of affected participants, are also needed. Design: Participants with the RUNX1 mutation will be screened. They will have a physical exam with blood tests. They will have a test of their heart function. They may need a new bone marrow biopsy if they haven't had one in the past year. Imatinib is a tablet taken by mouth once a day, every day, at home. Affected participants in different parts of the study will take imatinib for either 28 days or up to 84 days. They will fill out questionnaires about how they are feeling. For the first part of the study, participants will have blood tests every 2 weeks, either at home or at the NIH, while they are taking the imatinib. They will have a follow up visit, at home or at the NIH, when they are done taking imatinib on Day 28. Participants on the second part of the study will come to NIH on days 1 and days 84. They will have blood tests every 2 weeks (at home or the NIH) while they are taking imatinib. They may opt to have a bone marrow biopsy repeated after they finish their course of imatinib. Participants will have a follow-up visit (at home or the NIH) 30 days after they stop taking imatinib. Participants who do not have the RUNX1 mutation will have 1 clinic visit. They will have blood tests. They will fill out questionnaires. They may opt to have a bone marrow biopsy.
