Magnetic Resonance Imaging [PDF]
European Neurology, 1989 All of the data published in the literature show that MR is more sensitive than CT in diagnosing cerebral ischemic lesions. This greater sensitivity is due to its ability to detect even the minimal changes in tissue water content which occur in the early phases of the infarct.

Autonomous Magnetic Resonance Imaging [PDF]
Magnetic Resonance Imaging, 2020 AbstractAccess to Magnetic Resonance Imaging (MRI) across developing countries from being prohibitive to scarcely available. For example, eleven countries in Africa have no scanners. One critical limitation is the absence of skilled manpower required for MRI usage. Some of these challenges can be mitigated using autonomous MRI (AMRI) operation. In this
