Impact of Reconstruction Method (ASIR, FBP) Used in CT on Bone SPECT/CT Image Quality

NCT01800084 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 75

Last updated 2025-11-17

No results posted yet for this study

Summary

The main objective of this study is to demonstrate the non-inferiority of SPECT image quality (as measured by the signal / noise ratio) obtained by ASIR reconstruction of very-low-dose CT acquisitions versus the quality of those obtained by filtered back projection (FBP) of low-dose CT acquisitions.

The lower limit of non-inferiority is set to -1, the average SPECT signal / noise ratio TEMP expected is between 5 and 6.

Conditions

  • SPECT-CT

Interventions

DEVICE

Asir Image Acquisition

In addition to their normal image acquisition, a supplementary image acquisition lasting approximately 20 seconds (i.e. an ASIR image acquisition) will be carried out for each patient.
