### Reporting Systems  
Respondents expressed their appreciation for the presence of a \"Conclusions\" section at the end of the MRI report (Table 3). In their experience, such a section is frequently present (45/62, 72.6%) and, for most people (38/62, 84.5%), represents a helpful tool in clarifying the report and/or in adding information relevant to the patients' management. Although clinicians reported a similar average reading time for descriptive and qualitative reports, with an overall similar perceived quality, the revision of MRI images occurs more frequently after reading a descriptive report (53/61, 86.9%) than a structured one (8/61, 13.1%). ### Reporting Systems
