Trial Information

Evaluation of PET-MRI in Initial Staging of High Grade Rectal Cancer Patients and in the Follow up of Colorectal Cancer Patients.


I. To test the diagnostic performance of PET- MRI in the staging of preoperative high-grade
rectal cancer patients, defined by T3 stage or higher or N1 stage or higher or presence of
metastasis, that are referred to PET-CT and MRI.

II. To test the diagnostic performance of PET-MRI the follow up of colorectal cancer
patients that are referred to PET-CT with or without a diagnostic MRI request by their


I. To test different attenuation correction MR sequences and novel diagnostic MR sequences.


Patients undergo fludeoxyglucose F 18 PET-CT and PET-MRI.

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

Type of Study:


Study Design:

Endpoint Classification: Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Diagnostic

Outcome Measure:

Sensitivity for PET-CT and PET-MRI

Outcome Description:

Calculated with its 95% confidence interval using the standard formulas according to the criterion standard. Continuous variables will be expressed as mean and standard deviation. Comparisons between continuous variables will be performed by using the Student t test. Comparisons between qualitative variables will be performed by using the chi-square test with the Yates' correction or McNemar's test as appropriate.

Outcome Time Frame:

2 years
