Computed tomography (CT) perfusion has become a cornerstone of acute ischemic stroke imaging, extending treatment eligibility beyond conventional time windows and enabling individualized, tissue-based decision-making. Despite its widespread adoption, CT perfusion interpretation remains susceptible to technical, physiologic, and workflow-related pitfalls, which can significantly impact clinical management. Awareness of these pitfalls is essential to guide subsequent management decisions and to avoid inappropriate inclusion or exclusion of patients from endovascular therapy.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

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...
