Diagnosis value of ¹⁸F-FDG PET/CT and 3.0T MRI combined imaging in detecting the primary focus of breast cancer

Objective To explore the diagnosis value of ¹⁸F-FDG PET/CT and 3.0T MR combined imaging in detecting the primary focus of breast cancer.

Methods Thirty eight female patients with highly suspected breast cancer were selected, ¹⁸F-FDG PET/CT and 3.0T MRI imaging were performed and their pathological results were gotten within 7 days.

Results Twenty four malignant cases and 14 benign cases of the 38 patients were proved by pathology. The sensitivity, specificity and accuracy rate obtained by 3.0T MRI were 91.7%, 78.6% and 86.8%, respectively; they were 87.5%, 92.9% and 89.5% for ¹⁸F-FDG PET/CT; and which were 100.0%, 92.9% and 97.4% with ¹⁸F-FDG PET/CT and 3.0T MRI combined imaging. There were no significant difference among the three methods in the diagnostic ability(χ²=2.987, 1.612 and 2.955, all P > 0.05).

Conclusions The combination of ¹⁸F-FDG PET/CT imaging and 3.0T MRI imaging in detecting the primary focus of breast cancer has important value, and comparison with separate ¹⁸F-FDG PET/CT imaging or 3.0T MRI imaging, the diagnosis efficiency of three imaging methods in breast cancer without statistics difference.
