[Angioscanning in the diagnosis of breast neoplasms].

Angioscanning with macroalbumin J131 was performed in 30 patients with different mammary gland diseases (breast cancer--in 22, breast sarcoma--in 1, cystic fibroadenomatosis--in 6 and one patients without any breast pathology). Twenty eight of thirty patients were subjected to surgery, and the diagnosis was supported histologically. Injection of macroalbumin J131 in the subclavian artery enabled the authors to visualize malignant neoplasms, located mainly in the external quadrants of the mammary gland. The least size of the tumor, revealed by angioscanning, was 1.5 cm in diameter. The method of isotope injection directly in the subclavian artery, employed by the authors, may be recommended for patients, whose primary tumor is localized in the external half of the gland and in the axillary process.
