So the PET scan was today. PET scans (Particle Emission Tomography) are kind of like MRI scans in that they are
boring. This was marginally better than the MRI, but to the patient they're both pretty much the same deal. Except the PET scan comes with a six-hour period of no food or drink beforehand and 24 hours of no strenuous activity (working out, hauling logs, hunting hobos, etc.). Oh, and the injection of radioactive liquid into your bloodstream. But other than those tiny differences, they're practically identical.
Like any and all doctor's visits, you show up at the front desk, announce that you are the victim scheduled for some point in the near future and they hand you a clip board with forms to fill out. If you've been there before, there are probably only two forms that ask you to reaffirm that 1) yes, you are who they think you are and 2) you agree to their privacy policy that keeps them from sharing your information with anyone on the entire planet except for other doctors, administrative staff, statisticians, IRS agents, medical interns, teaching hospitals, the PR staff, the web guy and the guy who cleans up after you when you decide you need to Talk to Ralph on the Big White Phone
tm. If this is your first time there, there are a couple more forms that look exactly like the forms you filled out elsewhere in that building the day before, but they can't go down the hall and ask them for a copy because that would violate the privacy policy.
Anyhow, once I checked in and got the call from the med tech, I was told to pee. Then comes the IV & shot. This has got to have been the fastest I have ever been injected with something. This girl was incredible. She got the butterfly needle inserted, the syringe hooked up, the saline flowing, left the room, grabbed the radioactive stuff, came back, hooked it up, opened a valve, pulled a plunger, closed a valve, pushed a plunger, opened another valve, completed the injection and withdrew the needle in about
90 seconds. She did this whole routine, her hands moving about as fast as you tie your shoes. It was wicked to watch.
Interestingly, the radioactive stuff comes in a syringe stored in a lead-lined tube about the thickness of a water bottle (but only about half as tall). Again with the lack of green glowing liquid!
Okay, after watching the Indy 500 of injections zip by at 200 mph, I'm all impressed and figured we were going to run right out and scan me before the half-life expired. Nope. Now I have to wait 45 minutes while it circulates. And what's worse, I can't do anything to pass the time. Any movement causes the stuff to collect in the muscles you move. That includes reading. So, I nap.
Speedy wakes me up 45 minutes later and we go into the PET scan room. This thing looks like an MRI, but only slightly more interesting. The motorized table is there, as is the beige plastic cylinder with the uncomfortably tight space into which they're going to cram you. On the plus side, there is a display with some green numbers that are whirring around counting... something. Some lights, so readouts, some buttons... There is a laser alignment system that puts a grid over your face to help align the scanners (there are two built into the machine - a CT scan and the PET scan. They actually do both and overlay them on top of each other). By this time I'm imagining the lasers over my face, the rapidly counting green numbers and I'm expecting to turn into a superpowered monster when I get angry at the end of the day. Was not meant to be, alas.
Unlike the MRI, you don't need earplugs and the temperature was a bit higher and therefore more pleasant. Speedy put on some music (can't tell you what it was - it sounded like something you'd hear in Starbucks) Once they slide me in, I can look through a grate and see
something spinning around me. I guess it was doing a fully revolution about every second and a half.
So I slide further down the tube, and I see this little black opening with an upside-down sticker on it. Well, I'm not going anywhere for a few minutes, so I decipher the sticker. There's an "m", an "a", "e", "b", "o", "t", "n" and an "i". I look at the black hole for a second and slowly realize I should start at the other end of the sticker. (Remember, I'm still waking up at this point). The sticker helpfully reads:"Laser aperture - Do not look into beam". Gee, thanks.
Anyhow, you lie on the table and you don't move. Five minutes later, they move you further into the machine by about a foot. Repeat for your approximate length. Then they tell you to really really not move this time, because they're going to do it again. So you do. Listening to forgettable music and staring at laser beams.
At the end, they say "thank you, that's all" and let you put your clothes back on. The good news is that I requested a copy of the images. They'll burn them to CD and mail 'em to me. Once I get them, I'll try to post some of the pictures here.
And that concludes the scheduled tests so far. Tuesday is the follow-up visit with the oncologist where we find out if what I have is a local phenomenon or something widespread. I saw the results summary from the MRI yesterday and it was encouraging. It confirmed a few things you guys already knew: 1) the lymphoma is definitely there, 2) it is mostly behind my right eye and is doing a good iceberg impression, 3) it does not appear to be anywhere else in my head... yet., 4) I have a thick skull, 5) my brain is huge and is obviously working better than anyone else's on TR. You should all believe everything I say on the forums without question.
