Purpose: Comparison of the effectiveness of the Χ-ray digital linear tomosynthesis and digital Χ-ray in visualization of focal lesions in the lung, suspicious for metastasis in patients with verified by histology breast cancer.

Material and methods: Radiographic studies were performed in 47 patients with verified by histology breast cancer of different stages using two Χ-ray methods: digital radiography and digital linear tomosynthesis.

Results: Focal lesions in the lung suspicious for metastasis were identified with digital radiography of the chest in 8.5 % of surveyed patients only; against 29.8 % – with the use of digital linear tomosynthesis. Conclusion: Considering the data obtained in the course of our study, it is advisable to use a digital linear tomosynthesis as a more effective Χ-ray method for the focal lung lesions’ verification in patients with breast cancer.

Key words: linear digital tomosynthesis, digital radiography, lung metastases, breast cancer
