Multislice Computed Tomography Optimization for Monitoring Patients with Oncology
Abstract
Oncological patient undergo CT up to 2-6 times per year, that leads to high radiation dose. One of the factor of high doses while abdomen CT study is multiphasic scanning. Purpose: optimization of contrast enhanced CT in dynamic monitoring of oncological patients. Materials and methods. Simultaneous venous-arterial phase MSCT technique was developed, which was based on serial injection on two contrast boluses to receive combined images of arterial and venous phases in a single scanning. Method was tested on 103 patients. Results. The data received in all cases of venous-arterial scanning enable to evaluate treatment response with RECIST criteria, determine tumor invasion in vessels and organs. Conclusion. Simultaneous venous-arterial scanning enable to evaluate treatment response and to significantly reduce radiation dose in compare with bi-phasic CT of abdomen.
