Abstract:
Multidetector-row computed tomographic (CT) angiography of pulmonary arteries is the first-line imaging technique in patients suspected of having pulmonary embolism (PE). Patient risk stratification is important because optimal management, monitoring, and therapeutic strategies depend on the patient's prognosis. Acute right-sided heart failure is known to be responsible for circulatory collapse and death in patients with severe PE. Acute right-sided heart failure can be assessed on CT pulmonary angiography by measuring the dimensions of the right-sided heart cavities or systemic veins. The magnitude of PE can be calculated on CT pulmonary angiography by applying dedicated CT scores or angiographic scores adapted. This article reviews and discusses the various CT-based methods for risk stratification of patients with acute PE.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
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...
