Diagnosis of Tumors ▪ Nuclear medicine helps in the detection and characterization of certain tumors. Examples include evaluation of nodular thyroid disease as nodules that may be malignant. ▪ Scintimamography is another example used in selected patients when mammography is not conclusive. It is a simple procedure using intravenous injection of 99mTc MIBI followed by early and delayed imaging of the breasts and can indicate the nature of visualized lesions. ▪ Positron emission mammography (PEM) is recent being used in such cases. 6 Diagnosis of Tumors Negative radionuclide mammography study 7 Diagnosis of Tumors Focal accumulation of 99mTc MIBI in the right breast (arrow) proven to be cancer 8 Diagnosis of Tumors ▪PET/CT is also increasingly used for managing many types of cancer including detection. ▪Evaluation of the nature of solitary lung nodule and, in certain cases, of suspected breast cancer and tumor detection in cases with unknown primary are examples. 9 Diagnosis of Tumors Solitary lung nodule with high FDG activity (arrow) indicating malignancy 10 Diagnosis of Tumors 18F FDG-PET/CT study showing primary tumor in the right breast (solid arrow) and foci of lymph node involvement (open arrow) 11
