Multislice CT in tumor detection

This seminar will address the dramatic impact of multislice (multidetector) CT upon imaging the oncologic patient. This technology is responsible for a dramatic change in the speed and ability for diagnostic radiologists to detect disease. Technology has advanced rapidly in the last 20 years from single-slice CT scanners to helical (spiral) technology. Continuous acquisitions of multiple images represent the newest generation of scanners, referred to as multislice CT. Presently allowing four slices to be acquired simultaneously with newer scanners allowing eight-slice acquisitions. In this context I will address the fundamental technical principles behind these scanners and their impact on clinical protocols for the oncologic patient. © 2001 International Cancer Imaging Society.
