                         Radiology are discussed, underlining the basic philosophy of 
                         Quality and the difference between the concept of Quality Controls 
                         and Quality Assurance. A brief overview of QC in Computed 
                         Tomography is given describing the main advantages. The methods 
                         are similar in Magnetic Resonance Imaging (MRI) but far more 
                         complex. Therefore only the method for the measurement of 
                         Signal-to-Noise ratio (SNR) is examined in detail while the other 
                         image quality parameters are just mentioned. As an example of a 
                         right method for the evaluation of image quality in MRI, a new 
                         technique for the measurement of SNR based on a spatial 
                         frequencies domain analysis is proposed. Finally some guidelines 
                         for the personnel involved in QC activity are provided.",
