Low-dose computed tomography of the paranasal sinuses: radiation doses and reliability analysis
K Abul-Kasim, A Strömbeck… - American journal of …, 2011 - Elsevier
PURPOSE: The study aimed to (1) optimize the radiation doses of computed tomography
(CT) of paranasal sinuses,(2) compare the radiation doses of different CT protocols with that
of plain radiography, and (3) evaluate the reliability of low-dose CT in the detection of
pathology and characterization of the detected pathology. MATERIALS AND METHODS: A
head phantom was examined with different scan parameters to define a cutoff value to which
the radiation dose can be reduced without negative impact on image quality. Kruskal-Wallis …
