Feasability Of Contrast-Enhanced Ct In Breast Conservation Surgery For Invasive And Non-Invasive Breast Cancer.
JOURNAL OF CLINICAL ONCOLOGY(2017)
Abstract
e12084Background: MRI imaging has become the standard for planning breast conservation surgery for breast cancer. However, due partly to lack of resources of a small clinic practice, we have been utilizing contrast enhanced CT facilitated with ultrasound for this purpose. The aim of this presentation is to assess the feasability of contrast-enhanced CT in breast conservation surgery. Methods: We used GE Brightspeed-8 CT, with HP Z440 workstation (for free line masking). 100 mld of Iopamidol contrast medium was injected at a rate of 3 ml/sec and image capture was done at the 60 or 180 second phase. Images were taken with the patient in a supine position. We evaluate a total of 2057 cases operated in a ten year period between 2005.1.1 to 2014.12.31, excluding cases receiving preoperative chemotherapy. 1,757 cases (85%) were invasive and 300 cases (15%) were non-invasive breast cancer cases. Results: Lesion localization by contrast-enhance CT was acceptable by predefined criteria in 72% of invasive carcinoma...
