Whole body CT with only 1.5 mSv detects osteolytic lesions
Whole body CT with only 1.5 mSv detects osteolytic lesions
Very low-dose CT examinations can be achieved with low kV and tin filtering, reaching a total dose of 1.5 mSv for this whole-body examination. CT can now become a routine tool to detect and follow-up osteolytic lesions with a benefit of time and simplicity as compared to radiographs and MRI.
Key points:
- Spectral shaping using tin filtration is beneficial for whole-body low-dose CT.
- Sn 100 kV yields sufficient image quality for depiction of osteolytic lesions.
- Whole-body low-dose CT can be performed with a median dose of 1.5 mSv.
