214 Clinical Trials for Various Conditions
Flotufolastat F-18, sold under the brand name Posluma, is a radioactive diagnostic agent for use with positron emission tomography (PET) imaging for prostate cancer. The research is being done to study the capability of 18F-rhPSMA-7.3 (flotufolastat F-18) PET scan to detect prostate cancer when there are very low levels of Prostate-Specific Antigen (PSA) following previous radical prostatectomy surgery.
People with neuroendocrine cancer typically have imaging scans before and after treatment, including positron emission tomography (PET) scans. The scans are analyzed using a set of criteria that describes how the disease has responded to treatment. The purpose of this study is to establish new criteria for doctors to use when evaluating these PET scans. Researchers are testing whether these new criteria are useful for predicting whether a person's cancer gets better, gets worse, or stays the same. Researchers will also compare these new criteria to the current standard criteria for evaluating imaging scans.
The purpose of this study is to find out whether 68Ga-PSMA-11 PET/CT is effective in assessing tumor uptake (tumor activity seen in cancerous tissue) in participants with high-grade glioma/HGG or brain metastases.

Evaluation of Multi-Organ Metabolism and Perfusion in Non-Alcoholic Fatty Liver Disease (NAFLD) by Total Body Dynamic PET Scan on EXPLORER
The purpose of the study is to test 18F-BMS-986229 positron emission tomography (PET) imaging a practical and safe way to check the status of esophageal, stomach, and gastroesophageal junction cancer.
This trial studies how well digital PET scan works in predicting outcomes in patients with oropharyngeal cancer that has spread from where it started to nearby tissue or lymph nodes (locally advanced). The development of digital detectors for PET is a technological improvement in medical imaging that could potentially impact many areas of clinical oncology, including staging, radiation planning accuracy, and the assessment of treatment response. Digital technology may improve PET imaging performance by providing better timing, energy and spatial resolution, higher count rate capabilities and linearity, increased contrast, and reduced noise. Utilizing digital PET scan, may work better in predicting outcomes and treatment response in patients with oropharyngeal cancer compared to conventional PET.
The purpose of the study is to understand the extent and degree of somatostatin receptor expression in poorly differentiated neuroendocrine carcinomas . This may help to make a determination if a radiolabeled somatostatin analog therapy, also referred to as peptide receptor radiotherapy (PRRT), can be a potential alternative in the future. At this time, radiolabeled somatostatin analogs have not been tested in patients with poorly differentiated neuroendocrine carcinomas, and their efficacy in this disease is not well known Understanding the extent and degree of somatostatin receptor expression is important in order to evaluate the potential of radiolabeled somatostatin analog therapy for treatment of poorly differentiated neuroendocrine carcinomas.
The purpose of this study is to determine if Prostate-Specific Membrane Antigen (PSMA) positron emission tomography (PET) scans used in this study accurate and better at imaging participants' prostate cancer than the usual methods.
This study will evaluate the performance of physician readers trained to read flortaucipir-PET (positron emission tomography) scans.
This phase I trial studies how well \[18F\]DASA-23 and positron emission tomography (PET) scan work in evaluating pyruvate kinase M2 (PKM2) expression in patients with intracranial tumors or recurrent glioblastoma and healthy volunteers. PKM2 regulates brain tumor metabolism, a key factor in glioblastoma growth. \[18F\]DASA-23 is a radioactive substance with the ability to monitor PKM2 activity. A PET scan is a procedure in which a small amount of a radioactive substance, such as \[18F\]DASA-23, is injected into a vein, and a scanner is used to make detailed, computerized pictures of areas inside the body where the substance is used. Tumor cells usually pick up more of these radioactive substances, allowing them to be found. Giving \[18F\]DASA-23 with a PET scan may help doctors evaluate PKM2 expression in healthy volunteers and in participants with intracranial tumors or recurrent glioblastoma.
Investigators will use Axumin PET/CT to help with the imaging modalities to determine the presence of occult retroperitoneal disease.
Cognitive impairment occurs in as many as 80% of lupus patients and affective disorders, depression and anxiety, are also common. Both of these problems contribute significantly to disease burden and disability. Associations between serum anti-NMDAR Aab and cognitive and behavioral changes in human SLE have remained controversial, however, elevated titers of these Aabs in cerebrospinal fluid (CSF) correlate with severe central nervous system manifestations, such as coma and psychosis. The aim is to study the progression of disease (cognitive and behavioral impairment) over a 2 year period in SLE subjects with neuropsychologic and behavioral testing and correlates of disease progression using resting FDG-PET and serum Anti-NMDAR Aab. The correlations between hippocampal hypermetabolism, Anti-NMDAR Aab and memory impairment observed in the cross-sectional studies will be validated by baseline measurements in the proposed studies.
This is a single-arm, open-label study to assess the safety and effectiveness of a single dose of oral propranolol in reducing18F-fluorodeoxyglucose (FDG) uptake in brown adipose tissue (BAT) in pediatric oncology patients. This study is designed to better understand if taking a single dose of an oral medication called propranolol can reduce the chance of brown fat showing up on a PET scan, and therefore make the scan more accurate and easy to interpret. All humans have some degree of normal brown fat (called brown adipose tissue), and this normal tissue can sometimes light up on a PET scan. That creates problems because it may be wrongly interpreted by the radiologist as tumor, or it may hide true areas of tumor underneath it. Participants will not be randomized and will receive a single dose of oral propranolol approximately 60 minutes prior to the injection of the FDG tracer. The dose of propranolol will be 20 mg for all participants.
Neuroendocrine cancer is an unusual disease and often goes undetected by routine imaging. The 68Ga-DOTATATE PET Scan is a novel scanning method that may have improved sensitivity and resolution specifically for neuroendocrine tumors. Patients with neuroendocrine tumors will be imaged with this agent and it will be compared to conventional imaging methods to determine the safety and efficacy of this radiopharmaceutical.
When evaluating prostate cancer patients for recurrent disease, computed tomography (CT), and magnetic resonance imaging (MRI) are both highly sensitive methods for detecting lymph nodes, but are not specific as to whether the lymph nodes are malignant or benign. While positron emission tomography (PET) utilizing radioactive glucose (FDG) has revolutionized staging, restaging, and monitoring response to therapy in many prevalent cancers such as breast, colorectal, esophageal, head and neck, lung, lymphoma, and melanoma, findings with prostate cancer have proven less sensitive because prostate cancer has a lower avidity for glucose. A newer PET isotope, utilizing acetate that is incorporated into the cell membrane of rapidly proliferating cells, has shown greater sensitivity than FDG in detecting prostate cancer. This study will assess the clinical effectiveness of utilizing \[11C\]Acetate PET scans in identifying recurrent prostate cancer.
Neuroendocrine cancer is an unusual disease and often goes undetected by routine imaging. The 68Ga-DOTATATE PET scan is a new generation of scans that might have improved sensitivity and resolution specifically for neuroendocrine tumors. The investigators will scan people with this cancer and compare it to other conventional imaging methods to see if it improves patient care.
RATIONALE: Drugs used in chemotherapy, such as doxorubicin hydrochloride, bleomycin sulfate, vinblastine, dacarbazine, cyclophosphamide, etoposide, procarbazine hydrochloride, vincristine sulfate, and prednisone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x rays to kill cancer cells. Giving combination chemotherapy together with radiation therapy may kill more cancer cells. Comparing results of imaging procedures, such as PET scans and CT scans, done before, during, and after chemotherapy may help doctors predict a patient's response to treatment and help plan the best treatment. PURPOSE: This phase II clinical trial studies how well chemotherapy based on PET/CT scan works in treating patients with stage I or stage II Hodgkin lymphoma.
RATIONALE: PET scans done during chemotherapy may help doctors assess a patient's response to treatment and help plan the best treatment. PURPOSE: This randomized phase II trial is studying PET scan imaging in assessing response in patients with esophageal cancer receiving combination chemotherapy.
The hypothesis is that switching calcium based phosphate binders to sevelamer carbonate will be associated with less inflammation including less atherosclerotic plaque inflammation (inflammation of the vessel walls).
RATIONALE: New imaging procedures, such as fluorine F 18 fluorodopa-labeled PET scan, may help in guiding surgery and radiation therapy and allow doctors to plan better treatment. PURPOSE: This clinical trial studies fluorine F 18 fluorodopa-labeled PET scan in planning surgery and radiation therapy in treating patients with newly diagnosed high- or low-grade malignant glioma
This research is being done in order to improve treatment outcomes in patients diagnosed with bulky, early stage Hodgkin lymphoma and to reduce the side effects that are associated with use of radiation used in current treatments. The chemotherapy treatment in this study consists of a combination of four drugs approved by the Food and Drug Administration (FDA): doxorubicin, bleomycin, vinblastine, and dacarbazine. This regimen (called ABVD) has been found to be effective in treating patients with Hodgkin lymphoma and is considered the standard of treatment used with radiation therapy in patients with bulky early stage Hodgkin lymphoma. As part of the evaluation of the effectiveness of the chemotherapy treatment, PET scans will be obtained during the course of therapy. The usefulness of this PET scan will be evaluated to determine whether radiation may be left out in the treatment of disease if the PET scan shows that the patient has responded to chemotherapy alone. The plan is to identify a group of patients using early PET scans in order to change to a chemotherapy treatment called BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine and prednisone). It is one of the most highly effective chemotherapy regimens for Hodgkin lymphoma, but is associated with more side effects than ABVD. Although it has become standard of care in Europe, its use has been more limited in the U.S. because of concerns about toxicity.
The primary objective of the study is to determine the progression-free survival \[PFS\] at 36 months for patients with Hodgkin lymphoma who achieve a complete metabolic response as demonstrated by a negative fluorodeoxyglucose (FDG)-PET scan after one cycle of ABVD (adriamycin, bleomycin, vinblastine, dacarbazine) who undergo abbreviated ABVD chemotherapy (3 cycles).
The purpose of the research is to determine how practicing laparoscopic motor tasks affects the functional anatomy of the brain, and to investigate whether there is a correlation between surgical experience and functional brain activition. Additionaly, the investigators plan to use eye-tracking technology to see if the use of this technology can distinguish surgeons of various skill levels. The investigators hope that this study leads to new and effective methods of training surgical residents. All of the data will be collected at The Feinstein Institute for Medical Research, and may be used in future studies, which may or may not be related to urological diseases.
