RT Journal Article SR Electronic T1 Testing Different Storage Conditions for 99mTc-MAG3 Kit: Can Hot Fractioning Reduce the Cost per Unit Dose? JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 74 OP 75 VO 31 IS 2 A1 Kıratlı, Pınar Özgen A1 Volkan Salancı, Bilge YR 2003 UL http://tech.snmjournals.org/content/31/2/74.abstract AB Since its release for routine clinical use, 99mTc-mercaptoacetyltriglycine (MAG3) has become an important alternative to 131I-labeled orthoiodohippuran. The cold kit for MAG3 is expensive, especially in developing countries. Therefore, unique storage conditions should be provided for cost reduction. Cold fractioning is a well-known procedure but has special requirements, such as a nitrogen tank and a laminar flow hood. The aim of this study was to prolong the shelf life of 99mTc-labeled MAG3 by a hot fractioning method, which separates the patient doses after 99mTc labeling. The radiochemical purity of the 99mTc-labeled MAG3 kit was tested under different storage conditions. Hot fractioning of the 99mTc-labeled MAG3 kit was found to be a possible alternative to cold fractioning for routine clinical studies.
