Abstract

[^99mTc] liposomes (TL) and [¹¹¹In]WBCs (WBCs) were compared for imaging colitis in rabbits. At 24 h, liver was the major organ of accumulation (7.8% TL vs 39.7% WBCs), besides blood (44.1% TL vs 24.4% WBCs) and spleen (0.3% TL vs 7% WBCs). The inflamed colon accumulated 37.1 times more of [^99mTc] liposomes than the normal colon whereas the ratio was only 15.2 in case of [¹¹¹In] WBCs. The study demonstrates the usefulness of [^99mTc] liposomes for imaging inflammatory bowel diseases.
