Pathological Findings The planar and SPECT/CT photos revealed enhanced uptake of [99m Tc]Tc-DB15 in the planar and SPECT/CT pictures revealed improved uptake of [99mTc]Tc-DB15 inside the the BC metastases in both sufferers. Patient history and further facts concerning the BC metastases in each sufferers. Patient history and additional data concerning the study could be discovered within the Supplementary File. Patient 1 displayed elevated [99m Tc]Tc-DB15 uptake in the bones (spine, sternum, ribs and pelvis), which correlated with osteosclerotic lesions on the CT scan (Figure 1 and Figure S3 in Supplementary File) as well as with bone lesions revealed by [18 F]FDG PET/CT (Figure S4; Supplementary File). On the other hand, [99m Tc]Tc-DB15 failed to demonstrate intraperitoneal metastases through SPECT/CT which have been identified by [18 F]FDG PET/CT and subsequently Phenmedipham MedChemExpress confirmed in histopathology (not such as GRPR-expression status).with bone lesions revealed Supplementary File.
