Rationale And Objectives: To quantify the power or energy consumption of reporting stations in a radiology department and to consider a hypothetical scenario to reduce energy waste.
Methods: We measured the energy consumption of 36 radiology reporting stations over a mean time frame of about 194 days and then extrapolated results to 1 year. Reporting stations were configured (by default) to enter a stand-by mode after 4 hours of inactivity.
Article Synopsis
- The study compared the image quality and radiation dose of abdominal split-filter dual-energy CT (SF-DECT) with monoenergetic imaging to single-energy CT (SECT) using automatic tube voltage selection (ATVS).
- Results showed that SF-DECT produced images with 18% lower noise and better contrast-to-noise ratio (CNR) than SECT, while also having a significantly lower radiation dose (size-specific dose estimate).
- Overall, SF-DECT delivered comparable image quality and diagnostic confidence at reduced radiation levels, making it a favorable option in abdominal imaging.

Purpose: To assess the accuracy of iodine quantification in a phantom study at different radiation dose levels with dual-energy dual-source CT and to evaluate image quality and radiation doses in patients undergoing a single-energy and two dual-energy abdominal CT protocols.
Methods: In a phantom study, the accuracy of iodine quantification (4.5-23.

Objectives: To evaluate the impact of model-based iterative reconstruction (MBIR) on image quality and low-contrast lesion detection compared with filtered back projection (FBP) in abdominal computed tomography (CT) of simulated medium and large patients at different tube voltages.
Methods: A phantom with 45 hypoattenuating lesions was placed in two water containers and scanned at 70, 80, 100, and 120 kVp. The 120-kVp protocol served as reference, and the volume CT dose index (CTDI) was kept constant for all protocols.
