Detection of cold bone metastasis by Tc-99m MIBI imaging

An automated method for preparation of [(18)F]sodium fluoride for injection, USP to address the technetium-99m isotope shortage

The worldwide shortage of technetium-99m has created an immediate and urgent need for access to [(18)F]sodium fluoride for PET imaging of bone metastasis. In order to facilitate global availability of [(18)F]sodium fluoride for diagnostic nuclear medicine imaging procedures, a straightforward method for rapid production of [(18)F]sodium fluoride for injection, USP, using a modified GE Tracerlab FX-FN is presented.

"Double imaging" for the diagnostic work-up of alveolar soft part sarcoma with Tc-99m MIBI

The authors report a case of alveolar soft-part sarcoma with lung metastases demonstrated by "double imaging" with Tc-99m HDP and Tc-99m MIBI. The tumor originated in the soft tissue with direct invasion to the right scapula, which was hypoactive on bone scan and hyperactive on Tc-99m MIBI images. A focus of dense accumulation of Tc-99m MIBI in the lungs, suggesting metastasis was also demonstrated.
