Patient organ and effective dose estimation in CT: comparison of four software applications.

Background: Radiation dose in computed tomography (CT) has become a topic of high interest due to the increasing numbers of CT examinations performed worldwide. Hence, dose tracking and organ dose calculation software are increasingly used. We evaluated the organ dose variability associated with the use of different software applications or calculation methods.

Analysis of a multicentre cloud-based CT dosimetric database: preliminary results.

Background: To manage and analyse dosimetric data provided by computed tomography (CT) scanners from four Italian hospitals.

Methods: A radiation dose index monitoring (RDIM) software was used to collect anonymised exams stored in a cloud server. Since hospitals use different names for the same procedure, digital imaging and communications in medicine (DICOM) tags more appropriate to describe exams were selected and associated to study common names (SCNs) from a radiology playbook according to scan region and use of contrast media.
