Objective:

To explore the feasibility of a high-pitch CTPA protocol using ultra-low contrast volume for detecting pulmonary embolism compared to standard CTPA, focusing on diagnostic accuracy and patient safety.

Key Findings:
  • High-pitch CTPA demonstrated comparable image quality to standard CTPA despite using significantly less contrast medium.
  • The high-pitch mode reduced scan time and motion artifacts, improving patient compliance.
Interpretation:

The high-pitch CTPA protocol is a feasible alternative to standard CTPA, offering reduced contrast volume that may enhance patient safety without compromising diagnostic quality.

Limitations:
  • Single-center study may limit generalizability.
  • Retrospective design may introduce selection bias, potentially affecting the reliability of results.
Conclusion:

High-pitch CTPA with ultra-low contrast volume is a promising approach for PE detection, enhancing patient safety while maintaining diagnostic efficacy, which could influence future CTPA practices.
