Abstract:
Magnetic Resonance Imaging „MRI‟ is one of the most important diagnostic techniques around the world. It gives high resolution to soft tissues. The MRI machines are costly, difficult to maintain, and need huge amount of time for maintenance. This study is conducted in Sudan, investigating ten medical centers in Khartoum state in period from June to November 2018 with different MR machines.
The critical measurements of superconductive machines showed a direct relation between the chiller temperature and compressor failure, also a direct relation between the workload/day and helium consumption/day. The results of this study demonstrates the great effect of completing daily QC and machines quarterly maintenance, on the reduction of the problems and failures associated with MR machines operating. Also shows that the lack of maintenance is one of the biggest problems in MRI department‟s, and that the economical and political situation of the country plays a major role in this matter. The study also compares the local centers‟ questionnaires with the international ones, finding that some of local centers don‟t have MRI safety questionnaire, and others ignored some important questions.
This study concluded that the massive use of MR equipment and neglecting periodic maintenance are important factors in the breakdown of equipment
