Protocol for the realization of breast scintigraphy with 99mTc-MIBI using a prone decubitus positioning device

Breast cancer is the second most frequent neoplasm in the Cuban woman. Image techniques play a fundamental role for the diagnosis, staging and monitoring of the disease. This work had the objective of: Implement the Clinical Protocol for the scintimammography with 99mTc-MIBI for the detection of palpable tumor lesions in dense breasts, difficult mammographic assessment and suspected axillary metastatic lymph nodes employing a craft device of prone decubitus positioning. 35 patients were included with an average age of 51 years, who attended the central consultation of breast pathology at Dr. Salvador Allende Hospital. It was designed and constructed an artisanal device that made it possible to carry out the studies from an anatomical position pendant or pendulum of the breast, demonstrating its usefulness in the medical assessment of the scintimammography images. Of the studies carried out 17.1 % was positive for malignant mammary neoplastic tissue, with a specificity of 100 %. The number of unnecessary biopsies by false positive mammograms or inconclusive in lesions greater than 10 mm in diameter was decreased by 82.9 %. The clinical protocol was implemented for the scintimammography with 99mTc-MIBI for the detection of palpable tumor lesions in dense breasts, difficult mammographic assessment and suspected axillary metastatic lymph nodes employing a craft device of prone decubitus positioning. It proved to be a simple, reproducible and non-invasive test, which can facilitate and improve the diagnosis of breast cancer. (author)
