[Breakeven Analysis for Imaging Devices: Basic Introduction with Presentation of a User-Friendly Tool for in-clinic Calculation Using PET/CT as an Example].

Background: Imaging devices such as PET/CT are becoming increasingly important in view of the growing range of innovative nuclear medicine diagnostic procedures. Since the procurement and commissioning as well as the ongoing operation of imaging devices leads to comparatively high costs, it is of great interest for clinics and practices to know the number of scans from which the (planned) device operation leads to a profit. In the following, we will introduce the breakeven point analysis and present a calculation tool that users in nuclear medicine clinics and practices can use in everyday operations using PET/CT as an example.

Workflow efficiency of two 1.5 T MR scanners with and without an automated user interface for head examinations.

Rationale And Objectives: Workflow efficiency and workload of radiological technologists (RTs) were compared in head examinations performed with two 1.5 T magnetic resonance (MR) scanners equipped with or without an automated user interface called "day optimizing throughput" (Dot) workflow engine.

Materials And Methods: Thirty-four patients with known intracranial pathology were examined with a 1.
