positive ct and mri, negative pet scan

My mom has colon cancer. CT and MRI showed metastasis in liver (4 areas), one in pelvis and one in pancreas. We were told that having surgery was no longer an option and prognosis much poorer. Surgeon sent mom for a pet scan. Pet scan showed none of those areas lit up. Now surgeon wants to resume the plan of getting the colon removed and feels that the 4 masses in her liver, one in her pancreas, and one in her pelvis are not cancer after all. We don't know what to think.  Any insight? Would a single pet scan disprove a ct and an mri with contrast?

Have you received a answer on the scans?  I have the same question, PET and MRI do not give same diagnosis.

Hello there. I hope this info helps. I am a Radiologic Technologist by profession and this is my opinion.

PET SCAN is more conclusive compared to MRI and CT Scan. MRI and CT Scan tends to be subjective to the skill, notion, and experience of both the operator and Radiologist. PET SCANS rely on radionuclide and tracers which make it the most sensitive radiologic modality for the assessment of lesions.

To confirm the abnormal test results, you need additional tests like colposcopy and cervical biopsy to find out how severe the changes are actually. Read more https://expressclinics.in/cervical-cancer-screening/

Sometimes cervical cancer screening results are not accurate. It is observed that the result is showing abnormal cells where as actually there are such cells. This is known as False-positive result. Sometimes, the result shows no presence of abnormal cells where as there are abnormal cells. This is known as False-negative. To avoid these results, you need to use hygiene products before 2 days of test and stop doing sexual intercourse. Women are suggested not to do the test during the menstrual period.
