    CT pulmonary angiography (CTPA) is essential for diagnosing acute pulmonary embolism, enhanced by spectral CT technology.

  • 2

    Ultra-high resolution photon-counting detector (UHR-PCD) technology improves image quality and reduces radiation dose in CTPA.

  • 3

    Iodine maps from spectral CT provide functional information, aiding in the detection of small peripheral pulmonary emboli.

  • 4

    This study compares UHR-PCD-CTPA with dual-energy EID-CTPA to evaluate image quality and diagnostic benefits.

  • 5

    Objective and subjective assessments of image quality were conducted by radiologists to determine the effectiveness of UHR-PCD-CTPA.
