Abstract:
Blood Oxygen Level-Dependent (BOLD) MRI signal is a new method of renal functional imaging which allows renal cortical and medullary oxygen contents measurement in a noninvasive way and without injection of potentially nephrotoxic contrast product. Several clinical and experimental studies showed its potential interest in measuring renal oxygen content and its variation during different renal injuries, allowing new progress in the comprehension of the pathophysiology of several nephropathies.

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
