HEALTH ALERT!  For the safety of our patients and staff, effective March 30, 2020, new patients and patients with disabilities will be permitted one visitor over the age of 15. No other visitors will be permitted into the clinic.  Family members and caretakers may participate in the appointments remotely by phone or video conference if desired. Compass is working with other health care providers in the area to help contain the spread of the novel Coronavirus. We are taking active steps to minimize your exposure to the virus. These steps include screening everyone who enters the clinic for signs of illness, banning most visitors in the clinic, minimizing our own staffing and allowing some employees to work from home, and frequent sanitation of the clinic. We are using personal protective equipment such as masks, gowns, gloves, and face-shields according to national guidelines. We are working to identify those patients whose visits or treatments can be safely delayed, and we will notify you of this if you have an upcoming visit.  We ask that you stay home if you have fever and/or cough.

PET/CT Scans

PET/CT (Positron Emission Tomography and Computer Tomography) scanning technology is one of the most advanced cancer detection evaluations available to residents of the Portland, Oregon and Vancouver, Washington area. Compass Oncology is an ACR Accredited Facility for both PET and CT. This means our facility has met the standards for the highest level of quality and radiation safety. Our staff has been thoroughly reviewed and accredited by the American College of Radiology, a national professional organization serving radiologists, radiation oncologists, nuclear medicine physicians and medical physicists.

What Does a PET/CT Scan Do?

PET/CT Scans are a powerful combination of two imaging technologies:

  • PET shows the body's metabolic activity. Essentially it shows how fast the body is processing a glucose solution the patient is injected with before the scan is conducted. Cancer metabolizes sugar faster than normal cells. This higher level of activity appears as a bright spot on the scan. This allows cancer cells that would otherwise be undetected to appear.
  • CT scans show the body's anatomy. 

This gives your oncologist a higher degree of confidence in the location of the cancer and its stage. The types of cancer that are most commonly evaluated with a PET/CT scan include: breast, esophageal, cervical, melanoma, lymphoma, lung, colorectal, head and neck, and ovarian cancers.

Is a PET/CT Scan Right for Me?

A PET/CT scan may be the best available tool to diagnose the presence of cancer at an early stage and also to correctly assess the stage of disease when it is present. These factors are critically important if your doctor is to prescribe the right treatment, such as surgery, chemotherapy or radiation therapy. The combination of PET and CT is often the most accurate means of doing this. This advanced technique is also commonly used to assess how the cancer responds to this treatment.
