NT = not tested; NS = not significant.
For 99mTc-oxidronate, method 1 used ITLC/SG strips from Varian SA and method 2 used ITLC/SG strips from Pall Corp. For 99mTc-tetrofosmin, method 1 used chromatography paper from Varian SA and method 2 used ITLC/SG strips from Pall Corp. For 99mTc-exametazime, method 1 used chromatography paper from Varian SA and method 2 used ITLC/SG strips from Pall Corp. P values compared data from NCWC generators with those obtained from NFDC or NFWC generators.
