Abstract:
Ventilation/perfusion scintigraphy is the diagnostic tool of choice for detection and monitoring of pulmonary embolism. However, the knowledge on its value for other or concurrent pathologies is poor. In this review scintigraphic characteristics of the main pathologies, interpretation and artefacts are described. Together with the understanding of pathophysiology of the lung, the potential gain of information derived from ventilation/perfusion scintigraphy is much higher than generally believed. In conclusion, ventilation/perfusion scintigraphy not only in PE but also in other lung diseases is underused, its value and clinical potential underestimated.

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...

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...

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
