RE: CEA numbers...what do they really mean? So my Mom's oncologist is excited because her CEA (Carcinal Embryonic Antigen?) numbers have gone from 69 to 10.5. As I understand it that means the number of live, cancer cells floating around in her blood have decreased dramatically.
Platinum SHM-CD is the ultimate compact disc utilizing the platinum in place of the aluminum to form the reflective coating in addition to the proven SHM-CD technology. 2016/07/27.
Using a maximum kVp causes a. decrease in mAs required, and a decrease in x-ray tube heating, prolongs filament and anode life, and minimized pt motion. MOST IMPORTANTLY, produces minimum patient dose.Also produces lower contrast.. initial phantom images-uses mAs for the AP lumbar spine-measure pt thickness. kVp is selected from the kVp chart and required mAs is estimated based on previous experience. 2. Select optimal phantom image-do not alter kVp from the value shown for a part thickness, but instead determine the appropriate mAs.
