Dear MDCT.net users,

Since the introduction of CT in the 1970s, the technological features of this imaging modality have progressively advanced, leading to the development of multidetector CT scanners, first available in 1998. Technological developments have continued unabated, and today scanners with 64 detector-rows are routinely used in clinical practice. Recent improvements in the physical components, detector sizes and configurations of CT systems are promising to further improve the diagnostic accuracy of CT examinations and to allow the development of new clinical applications.

In light of the rapid advances in MDCT, the newsletter illustrates the state-of-the-art CT instrumentation and highlights its clinical utility and potential. The newest CT scanners presented at RSNA 2013, held last December in Chicago, are summarized by J.F. Paul in the “Updates in Technology” column, while detector technology is reviewed in C. Catalano’s “Focus on”. A selection of recently published research papers illustrates the use of top-end CT scanners and iterative reconstruction algorithms in different clinical applications. Additionally, we highlight a health technology assessment comparing the efficiency and cost-effectiveness of two automated injection systems for contrast medium administration.

We believe these new publications will expand your knowledge of the technical characteristics and performances of the different scanner systems, not just the currently available ones but also those soon to be authorized for clinical use.
