简要总结
This trial studies how well 4 dimensional (D) positron emission tomography/computed tomography (PET/CT) works in diagnosing participants with lung or colorectal cancer that has spread to the liver and lung. Diagnostic procedures, such as PET/CT, may help find and diagnose disease and find out how far the disease has spread. But the motions made by breathing can reduce the image quality of the scan. Adjusting the scanner to 4D may allow for more breathing motion may improve the quality of the PET/CT images.
详细描述
PRIMARY OBJECTIVES:
I. Study the impact of 4D positron emission tomography/computed tomography (PET/CT) imaging on the evaluation and staging of lung and colorectal cancer.
OUTLINE:
Participants undergo 4D PET/CT scan over up to 12 minutes.
