[The radiation dose problem in computed tomography. Actual data and strategies for a corrected use of ionizing radiation in computed tomography].
New technologies in these years has taken to a spread and to a growth of the CT application with an increase of patients and population exposure. In clinical practice some technical devices can be used to reduce the exposure dose of multidetector CT that allows radiologist to answer the clinical question with less damage to the patient. The radiologist remains however the guarantor of the ionizing radiation exposition and he has to consider also the opportunity to use other methodics (MR, US) to answer some questions. The radiologist has the role to evaluate the clinical indication to the exam demanded from other doctor and has the responsibility for exam management and for progressive radiologic course, controls and follow-up.
