Tc-۹۹m MIBI imaging in lymphomas: Comparison with T۱-۲۰۱ and Ga-۶۷ scientigraphy

Tc-۹۹m MIBI has recently been used in the functional imaging of various tumors. This prospective study was performed to evaluate the role of Tc-۹۹m MIBI imaging at the time of the initial staging, assessment of treatment response, follow-up studies and survaillance in Hodgkin’s and non-Hodgkin’s Iymphoma. ۲۵ patients (۱۴ with Hodgkin’s and ۱۱ with non-Hodgkin’s Iymphoma) underwent ۳۲ studies. The patient’s age range wa ۱۹-۷۳ years, with a mean age of ۴۱.۷ years. All patients underwent whole body planar imaging following intravenous injection of ۲۰-۲۵ mCi Tc-۹۹m MIBI. Comparative imaging with ۳ mCi Tl-۲۰۱ and ۱۰ mCi Ga-۶۷ injection was done. Clinical, radiographic and biopsy correlation was obtained in all cases.
