Abstract

The aim was to study the diagnostic possibilities of breast scintigraphy with help of domestic RFP tehnetril labeled 99mTc. Breast scintigraphy was performed in 132 women at age between 32 and 68 years. Visualization of both breasts in planned mode was performed in the lateral and anterior projections in 10-15 minutes after intravenous injection of 740-860 MBq of 99mTc-tehnetril. After this, a study was conducted in the mode emission computed tomography. Morphological verification of changes in the breast was performed in all cases. Sensitivity, specificity and overall accuracy of planar breast scintigraphy was 96% (105/112), 94% (245/252) and 95% respectively. Upon planar study of 132 breasts suspicious on cancer presence breast scintigraphy showed not high specificity 68% (7/21), sensitivity reached 94% (105/112), overall accuracy—90%. SPECT did not show visible benefits: sensitivity — 92% (100/112), specificity—75% (5/21), and overall accuracy — 89%. Usage of a semi-quantitative accrual rate of RFP in tumor allowed distinguishing four groups of patients with different, to breast scintigraphy data, likelihood of breast cancer (from 2-10% to 96%). As a result current methods of breast scintigraphy provide high sensitivity (88-96%) and accuracy in breast cancer detecting of any size as far as the use of additional diagnostic criteria, semi-quantitative ratio RFP accumulation in tumor in particular, can significantly increase (up 94%), specificity of diagnostic conclusions.
