CT scanning and interstitial therapy.
Computerized tomography is of considerable value in determining tumor volume at many anatomic sites that are otherwise difficult to visualize. The ability to define volume accurately by means of a CT scan can be employed in interstitial radiotherapy. First, CT scan information may be used to plan the implant volume by defining the tumor location and extent prior to implantation of radioactive materials. Second, radioactive sources and/or afterloading devices can be localized after implantation by means of a CT scan. Third, follow-up of tumors to assess both tumor regression and recurrence is facilitated.
