Abstract:
The following article is intended to illustrate the place of scintigraphy and computed tomography pulmonary angiography (CTPA) in the investigation of acute PE in current practice, and to guide non-radionuclide radiologists and other medical professionals to the best test for patients. We share our early experiences with ventilation-perfusion (V/Q) single-photon-emission computed tomography (SPECT) including image acquisition and interpretation. A comparison of the two techniques is given, along with practical considerations in a variety of clinical scenarios.

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...

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...
