This prospective study aims to perform intra-individual comparison of the image quality between ultra-low-dose whole-body CT with deep learning reconstruction and conventional low-dose whole-body CT with iterative reconstruction in patients with suspected multiple myeloma.
Study Type
OBSERVATIONAL
Enrollment
30
noncontrast-enhanced low-dose whole-body CT using dual-source CT scanner using A-tube (75% radiation) and B-tube (25% radiation). * conventional low-dose CT data (A +B tubes, 100% dose) are reconstructed with iterative reconstruction * ultra-low dose CT data (B-tube only, 25% dose) are reconstructed with deep learning commercially available software.
