A study of using manganese chloride (MnCl2) solution as an alternative of contrast medium for iodine in computed tomography (CT) imaging

Abstract

Iodine solution is the only contrast medium currently used in the computed tomography scan (CT scan) examination. In the present study manganese chloride (MnCl2) solution has been chosen as alternative contrast medium in computed tomography scanning (CT scan). It was found that using MnCl2 solution as an alternative contrast medium in rabbits which enhanced the CT scan imaging in the resolution and increasing the Hounsfield unit (HU) values of heart and kidney organs in comparison with the iodine compound at the same doses. It was chosen the heart and kidney of rabbits to study the effect of using the iodine and MnCl2 solution as alternative contrast medium in CT scan imaging, the following results: the native has 45 HU for heart and 50.1 for kidney organ. While the results of using iodine solution at dose of 3 ml has 83 HU for heart and 164 HU for kidney organ. In the MnCl2 solution which used as alternative of contrast medium has 83 HU for heart and 70.3 HU for kidney at 2.5 ml of 0.5 molar of solution. From these results the resolution of CT scan image has well and clears when using the alternative contrast medium (MnCl2). We can concluded that the alternative contrast medium of MnCl2 solution has good HU values of both heart and kidney comparison with iodine solution.
