Osteosarcoma and Ewing sarcoma are the most frequent paediatric bone tumors, mainly affecting subjects aged between 10 and 19, and it is extremely rare in children before the age of 5 . Since both of these tumors have a high probability of lung metastases, patients undergo a CT scan every 3 months in the first two years after the onset of the illness, and then one CT scan a year.
It is compulsory to minimize the probability of radiation damage  so the low dose chest CT protocol should be studied to guarantee the detection of the small pulmonary nodules, but CT image quality should not be higher than needed for confident diagnosis .
The aim of this work was to analyze the CT protocols normally used in our paediatric department of radiology and verify their performance on the dosimetric and image quality point of view.
