subject: Advantages and Disadvantages of a PET CT Scan [print this page] All medical imaging software is valuable to doctors and healthcare professionals, but none more so than that developed for reading a combined pet ct scan. The PET scan can provide detailed information about any abnormal cells - in this respect it can detect abnormal cells, the speed at which they are developing and how much they have spread. A CT scan provides a detailed image of the body which provides a map and directions to the location of the cells. Working as a double team allows doctors to make better treatment plans and provide the most appropriate care for their patients. It is particularly effective as one of the tools used in providing oncology solutions and is also useful in a multitude of medical disciplines.
