This article describes the Magnetic Resonance Imaging (MRI) systems bydesigning and implementation of a modified cooling system for MRI Scanner to enhance Image Quality. The diagnostic MRI scanner based on heat exchanger technology to achieve sharper images by implementing the new cooling system on a 1.5T and 3T diagnostic scanner at our King Abdulaziz University Hospital and investigate the results of MRI scans obtained from fat saturation and gradient echo sequences. Also, demonstration the effectiveness of improvement in cooling water efficiency which is not only important from ecological considerations but also limit the high shield temperature that would affect the magnet cold head of the scanner in turn affecting on image quality.
