Deep learning-enhanced four-fold parallel acquisition (P4) significantly improves prostate MRI quality, increasing signal and contrast ratios. This advanced technique also halves scan times, enhancing diagnostic precision and workflow efficiency.

Area of Science:

  • Radiology and Medical Imaging
  • Artificial Intelligence in Healthcare
  • Magnetic Resonance Imaging

Background:

  • Prostate MRI is crucial for diagnosis and treatment planning.
  • Traditional parallel acquisition techniques (P2) face limitations in balancing image quality and scan time.
  • Deep learning (DL) offers potential to enhance MRI acquisition efficiency and image fidelity.

Purpose of the Study:

  • To evaluate the effectiveness of a DL-enhanced four-fold parallel acquisition (P4) technique for prostate MRI.
  • To compare P4 with the traditional two-fold parallel acquisition (P2) in terms of image quality and scan efficiency.
  • To assess the impact of P4 on diagnostic precision and workflow.

Main Methods:

  • Prospective analysis of 51 patients undergoing prostate MRI with both P2 and P4 T2-weighted sequences.

  • Independent reader assessment of image quality, signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR).
  • Radiomics analysis to evaluate differences in contrast and gray-level properties between P2 and P4.

    • Main Results:

    • P4 demonstrated significantly higher CNR and SNR compared to P2 (p <.001).
    • P4 was consistently rated superior in image quality and diagnostic precision (p <.001).
    • P4 reduced T2w scan times by 50.8% (from 11:48 min to 5:48 min, p <.001).

    Conclusions:

    • DL-enhanced P4 imaging significantly improves prostate MRI diagnostic quality.
    • P4 optimizes scan efficiency by reducing acquisition time, enhancing workflow.
    • The P4 technique supports a more patient-centered and sustainable radiology practice.
