This systematic review and meta-analysis evaluated the effects of photon-counting detector computed tomography (PCD-CT) versus energy-integrating detector computed tomography (EID-CT) on image quality and radiation dose in patients with multiple myeloma. The analysis included five studies with 170 patients, revealing a significant improvement in image sharpness (mean difference, +0.99 points) and a reduction in radiation dose (mean difference, -4.95 milligrays) with PCD-CT.
Key findings
- PCD-CT improved image sharpness by a mean difference of +0.99 points.
- PCD-CT reduced radiation dose by a mean difference of -4.95 milligrays.
- Trial sequential analysis confirmed the stability of pooled estimates for image sharpness.
- Evidence for radiation dose reduction remains suggestive but inconclusive.
Why it matters
Improving image quality while reducing radiation exposure is crucial in imaging patients with multiple myeloma. Enhanced diagnostic capabilities can lead to better patient management and outcomes, making this comparison relevant for clinical practice.
