Summary
Multislice CT (MSCT) generates more images per study than single-slice helical CT (SSHCT), increasing Picture Archiving and Communication System (PACS) demands. This advanced imaging technology significantly impacts PACS resource utilization and requires careful planning for efficient data management.
Area of Science:
- Radiology
- Medical Imaging Technology
- Health Informatics
Background:
- Single-slice helical CT (SSHCT) has been the standard for CT imaging.
- Advancements in CT technology have led to the development of multislice CT (MSCT).
- MSCT offers improved scan times and thinner slice capabilities compared to SSHCT.
Purpose of the Study:
- To evaluate the impact of multislice CT (MSCT) on Picture Archiving and Communication System (PACS) resources.
- To compare the number of images per study (IPS), average cycle times (ACT), and average number of studies per patient (ANSPP) between MSCT and SSHCT.
Main Methods:
- Weekly averages of IPS were collected for MSCT and SSHCT scanners.
- ACT and ANSPP were analyzed for MSCT and SSHCT scanners over specific periods.
- Statistical analysis was performed to determine significant differences (P <0.001, P <0.0001).
Main Results:
- MSCT scanners produced significantly more images per study (IPS) compared to SSHCT scanners.
- While ACT showed an initial significant difference (P <0.001) favoring SSHCT, it became non-significant after a certain period.
- ANSPP was significantly higher for MSCT scanners (P <0.0001) throughout the study periods.
Conclusions:
- Implementation of MSCT significantly increases the number of images generated per study and per patient.
- These increases place substantial demands on PACS resources, necessitating proactive resource management.
- Healthcare facilities must prepare for increased PACS workload with the adoption of MSCT technology.
