I would like to tell everyone about a new medical imaging test used to diagnose, stage and restage cancer patients. It will also tell if the therapy you are undergoing is working or not. It is called Integrated PET/CT. I'm sure most of you know about the PET scan, but I'd like to educate you about the integrated PET/CT scan.
Here is how the technology works:
A patient with or suspected of having cancer comes into our outpatient center. A small injection of a radioactive sugar is given to the patient. The sugar travels thru the body and gets “gobbled up” by cancer cells. Cancer cells metabolize the sugar and trap it. Since the sugar is radioactive, it gives off energies that can be captured and turned into a picture. PET scanning is not new; it has been around for over 10 years. As I mentioned earlier, the PET scan shows what is going on at the cellular level (cancer cells eating up the sugar). While this is very informative, the integrated PET/CT gives much more information to the physician so they can tailor the treatment more specifically to each patient. It works like this: When the patient lies down to be scanned, a whole body CT scan is done on the patient, which shows exemplary anatomic detail. The patient is then moved a little further into the tube to get the PET scan performed. Since these two tests are integrated into one machine, we can overlay the physiologic data (PET) with the anatomic data (CT) which will tell the patients physician exactly where the tumor is, and how they can plan their therapy to kill it. A PET/CT scan takes on average 20 minutes, while the more antiquated PET or software fused PET takes in excess of one hour, and is nowhere near as informative to the physician.
Most insurances (including Medicare) pay for PET/CT scans because they change the patient management up to 40% of the time, and may help avoid unnecessary and costly surgery.
If your physician has not suggested you get a PET/CT scan, ask them for one. This scan is extremely important in lung,colo-rectal, lymphoma, and breast cancers especially where there is mediastinal involvement or a question if there is chest wall involvement, or lymph node involvement. With the "fused" PET/CT, if there is a spot in the mediastinum, you will know exactly if it is a particular lymph node, or a mass, which is extremely important for Radiation Therapy planning or surgery. A plain PET scan or a PET scan that uses software fusion is not as accurate as an integrated PET/CT. It could make a world of difference...
I would be happy to answer any questions about the technology that I can.
