Effects of different levels of CT iterative reconstruction on low-contrast detectability and radiation dose in patients of different sizes: an anthropomorphic phantom study

Autor: Damien Racine, Paolo Fonio, Marco Gatti, Fatemeh Darvizeh, R. Ropolo, Alessandro Depaoli, Irene Ruggirello, Osvaldo Rampado, Filippo Marchisio, Valeria Ruggeri

The purpose of this study was to verify the maintenance of low-contrast detectability at different CT dose reduction levels, in patients of different sizes, as a consequence of the application of iterative reconstruction at different strengths combin

Autor: R. Ropolo, Osvaldo Rampado, Riccardo Faletti, Laura Bergamasco, Marco Gatti, Paolo Fonio, Marco Fronda, Filippo Marchisio

Publikováno v: Journal of Computer Assisted Tomography. 42:191-196

The aim of this study was to evaluate the impact on dose reduction and image quality of the new iterative reconstruction technique: adaptive statistical iterative reconstruction (ASIR-V).Fifty consecutive oncologic patients acted as case controls und

Autor: Marco Valerio, Stefania Busso, R. Ropolo, Osvaldo Rampado, Simona Capello, Ezio Marengo, Simona Veglia, Domenica Garabello, Ottavio Davini

Publikováno v: La radiologia medica. 121:291-300

The purpose of this study was to optimize an aorta angiographic CT protocol, by investigating the best combination of tube current modulation, iterative algorithm strength and kV reduction. Anthropomorphic phantoms of three sizes were imaged by CT wi
