Summary
Bone scintigraphy using technetium-99m diphosphonate effectively identified carcinoma in patients awaiting breast surgery. The imaging technique showed increased uptake in malignant cases, distinguishing them from benign conditions and healthy controls.
Area of Science:
- Nuclear medicine
- Radiopharmaceuticals
- Breast imaging
Background:
- Bone scintigraphy is a diagnostic imaging technique.
- Technetium-99m labeled diphosphonates are commonly used radiotracers.
- Distinguishing benign from malignant breast conditions can be challenging.
Purpose of the Study:
- To evaluate the utility of bone scintigraphy with 99mTc-diphosphonate in patients undergoing breast surgery.
- To assess the ability of this imaging modality to detect breast carcinoma.
Main Methods:
- Patients were studied using either 99mTc-polyphosphate or 99mTc-diphosphonate.
- Included patients undergoing bone scintigraphy or awaiting breast surgery.
- Control groups consisted of healthy individuals and patients with benign breast conditions.
Main Results:
- Seven out of eight patients with breast carcinoma showed focal areas of increased radiotracer uptake.
- Nine control subjects without breast disease had normal scintigraphic images.
- Increased uptake was also observed in benign conditions like gynecomastia, lactation, and inflammation.
Conclusions:
- Bone scintigraphy with 99mTc-diphosphonate demonstrates potential in identifying breast carcinoma.
- The imaging technique can differentiate malignant lesions from benign breast diseases and normal findings.
- Correlation with mammography and thermography supports its clinical utility.
