New CT method could slash radiation in bone scans
NCT ID NCT01800084
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a newer CT reconstruction method (ASIR) can produce bone SPECT-CT images as good as the standard method (FBP) while using less radiation. Researchers enrolled 75 patients scheduled for a SPECT-CT exam. They compared image quality by measuring signal and noise in the spine and aorta. The goal was to see if ASIR could reduce radiation exposure without sacrificing image clarity.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Adaptive statistical iterative reconstruction (ASIR) and filtered back projection (FBP) reconstruction methods
What this could lead to
If successful, this could allow doctors to use lower radiation doses during bone SPECT-CT scans without losing image quality, making scans safer for patients.
What could go wrong
This is a small, completed study focused on image quality, not on patient health outcomes. The results may not apply to all types of scans or patients.
