The goal of this diagnostic intervention clinical trial is to compare 18F-Fluciclovine uptake within brain lesions over 60 minutes compared with standard of care positive histology confirmation or confirmation MRI images. The main questions it aims to answer are: 1. What are the dynamics of 18F-Fluciclovine update within a non-treated metastatic brain lesion over 60 minutes? 2. What are the dynamics of 18F-fluciclovine update within recently treated metastatic brain lesions? 3. What is the potential use of 18F-Fluciclovine in delineating true local progression from radionecrosis in patients with clinical uncertainty of indeterminate MRI? Participants...
This is a Pilot/Phase I clinical study of hyperpolarized 13C (HP 13C) pyruvate injection that includes the acquisition of magnetic resonance (MR) data performed on participants with meningioma to evaluate metabolism and aid in the non-invasive characterization of aggressive tumor behavior
This phase I trial evaluates the feasibility of using hyperpolarized carbon C 13 pyruvate magnetic resonance imaging (MRI) in diagnosing patients with primary central nervous system lymphoma. This trial aims to see whether MRI using hyperpolarized carbon-13 pyruvate is safe and useful for detecting central nervous system lymphoma and evaluating response to treatment.
Gliomas are tumors that occur in all ages; they include the most common malign primary central nervous system tumors in developed countries. Gliomas are often aggressive, and their recommended treatment is surgical resection and chemoradiation. Complete tumor removal is challenging because of diffuse cell growth and the proximity of functionally critical tissues. Surgeons use 5-aminolevulinic acid (5-ALA) drug-induced fluorescence to visually detect tumor cells, which improves resection rates and delays tumor progression. Tumor cells are often left unnoticed because of visual obstacles or weak fluorescence, which may lead to local recurrence and reoperations. Surgical suction...
Evaluating the sensitivity and feasibility of using ctDNA assays optimized for detecting very low ctDNA counts from cerebrospinal fluid (CSF) and plasma. The investigators will evaluate the sensitivity of ctDNA from plasma and CSF at baseline (defined as Cycle1 Day1 (C1D1) pre-treatment) and over time in response to treatment with plixorafenib co-administered with cobicistat in BRAF-V600E mutant glioma refractory to prior therapies.
Background: Pituitary tumors can cause problems by secreting hormones in the body. They can also problems by growing large and pushing on organs near the pituitary gland. The best treatment for such tumors is to remove them by surgery. But that may be sometimes difficult. Some tumors maybe too small to see. Some other tumors maybe so large that portions maybe left behind during surgery. The endosphenoidal coil (ESC) is a new magnetic resonance imaging (MRI) device. It fits in a small space made during surgery near the pituitary. Researchers want to see if it helps transmit MRI signals during surgery to make better images of the pituitary gland and tumors. Objective: To...
This phase II trial studies how well ¹⁸F- fluoromisonidazole (FMISO) works with positron emission tomography (PET)/magnetic resonance imaging (MRI) in assessing participants with malignant (cancerous) brain tumors. FMISO provides information about the oxygen levels in a tumor, which may affect how the tumor behaves. PET/MRI imaging produces images of the brain and how the body functions. FMISO PET/MRI may help investigators see how much oxygen is getting in the brain tumors.
Low-grade glioma (LGG) represent typically slowly growing primary brain tumors with world health organization (WHO) grade I or II who affect young adults around their fourth decade. Radiological feature on MRI is a predominantly T2 hyperintense signal, LGG show typically no contrast uptake. Radiotherapy plays an important role in the treatment of LGG. However, not least because of the good prognosis with long term survivorship the timing of radiotherapy has been discussed controversially. In order to avoid long term sequelae such as neurocognitive impairment, malignant transformation or secondary neoplasms initiation was often postponed as long as possible
This clinical trial evaluates the use of microdialysis catheters during surgery to collect biomarkers, and studies the feasibility of intraoperative microdialysis during neurosurgery for central nervous system malignancies. A biomarker is a measurable indicator of the severity or presence of disease state. Information collected in this study may help doctors to develop new strategies to better diagnose, monitor, and treat brain tumors.
The study team hypothesizes that it is feasible to intraoperatively detect tumor following [CU64]DOTATATE injection using the gamma probe device.
