Radionuclide Diagnosis of Breast Cancers

摘要

To study the diagnostic capabilities of planar breast scintigraphy and single photon emission computed tomography (SPECT) with ~(99m)Tc-MIBI in visualizing of breast tumors, 61 patients with a diagnosis of breast cancer were included in the study. The results showed that sensitivity of the planar mode in identifying primary breast tumors was 46%. The sensitivity of SPECT in detecting primary tumor was 93.4%. The sensitivity of the planar mode in visualization of nodal metastases was 44.8%, against 93.1% in SPECT. This study showed that SPECT has a high diagnostic efficiency in regard of visualization of small sized tumors, multicenter tumor growth, identifying space-occupying lesions on the background of modified breast tissue.
