Abstract:
Acute cerebral ischemia or stroke is currently considered an emergency for which therapeutic options are available if the therapeutic window of 4.5 h is respected. Imaging modalities have progressed greatly over the last few decades, rendering ischemia detectable in the first hours after the event. However, in order for treatment to be efficacious it is necessary to speed up all the processes before the start of therapy. Thus, one must decrease the time to arrival at the hospital and to the radiological method that is to be employed (be it computed tomography or magnetic resonance imaging); only then will the medical or interventional techniques available fulfill their potential.

Radiological Investigation II: MRI and Ventilation Perfusion Scan
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...
