Area of Science:

  • Radiology
  • Medical Imaging Technology
  • Healthcare Operations

Background:

  • Diagnostic imaging centers face pressure to increase patient throughput.
  • Advancements in CT scanner technology aim to improve efficiency and diagnostic capabilities.
  • Single-slice CT (SSCT) has been the standard, but multislice CT (MSCT) offers potential for enhanced performance.

Purpose of the Study:

  • To evaluate the impact of multislice CT technology on scanner productivity within a tertiary care setting.
  • To compare the efficiency of MSCT versus SSCT in terms of patient examinations performed.
  • To quantify changes in CT scanner output following the introduction of MSCT.

Main Methods:

  • A comparative analysis of CT scanner productivity was conducted over two 8-month periods.

  • Data from a radiology information system was used to count CT examinations performed on SSCT and MSCT scanners.
  • Patient populations were controlled for by analyzing examination mix (enhanced/unenhanced, anatomic region).

    • Main Results:

    • Total CT studies increased by 13.1% (1772 examinations) after MSCT implementation.
    • The number of contrast-enhanced examinations rose from 52% to 65%.
    • The MSCT scanner performed 51.9% more examinations than the SSCT scanner during comparable daytime hours (p < 0.0006).

    Conclusions:

    • Multislice CT technology demonstrably increases CT scanner productivity and patient throughput.
    • Despite more complex protocols, MSCT enhances overall departmental efficiency.
    • Adoption of MSCT is a viable strategy for improving imaging service delivery in medical centers.
