Summary
This pilot clinical trial studies positron emission tomography (PET)-magnetic resonance imaging (MRI) and PET-computed tomography (CT) as diagnostic imaging in patients with colon and/or rectal cancer. New diagnostic imaging procedures, such as PET-MRI, may help find and diagnose rectal cancer or recurrence of colorectal cancer
Eligibility Criteria
Inclusion Criteria
- Either having a T3 (the cancer has grown through the muscularis propria and into the outermost layers of the colon or rectum but not through them) or higher, node positivity or metastatic lesion in the context of rectal cancer or being studied for colorectal cancer follow up, independent of the renal function
- PET-CT should be requested by a referring physician; in the case of having an MR requested as well, it will be reported from the MRI images generated in the PET-MRI
- Stable physical medical conditions to undergo a MRI
- Informed consent must be given and signed prior to study enrollment
Exclusion Criteria
- Refuse to give and/or sign the informed consent
- Subjects who do not meet the above mentioned inclusion criteria
- Subjects who have a pacemaker
- Subjects who have a metallic prostheses either in the pelvis or in the abdomen that will interfere with the MR imaging of that anatomical area
- Subjects who suffer from claustrophobia
- Pregnant women
- Cognitive impairment that affects the subject's ability to give consent
