Comparison of I-124 PET/CT for the Diagnosis of Thyroid Cancer
Recruiting
Persons diagnosed with thyroid cancer are often treated initially with a thyroidectomy, which is followed by ablation using Iodine-131, a therapy which has been shown to be effective and safe. Imaging of metastatic thyroid cancer has been performed with whole body I-131 and Iodine 123 (I-123) imaging for many decades and use I-123 for staging studies. Iodine 124 (I-124) is a radioisotope of iodine which emits a positron and is imaged using PET (positron emission tomography). This is a single arm... Read More

Imaging of Solid Tumors Using 18F-TRX
Recruiting
This phase I trial tests the safety and effectiveness of 18F-TRX in detecting tumors (cancer) patients with solid tumors. 18F-TRX is an imaging tracer that is used to visualize tumors using a PET scan. It specifically targets and detects labile (unstable) iron levels within tissues, including tumors. Diagnostic procedures, such as 18F-TRX PET/CT or PET/MRI, may help detect tumors in patients with solid tumors
