[Spiral computed tomography--solution to diagnostic problems in pulmonary embolism?].

Area of Science:

• Radiology
• Medical Imaging
• Cardiovascular Medicine

Background:

• Clinical diagnosis of pulmonary embolism (PE) is often challenging and relies heavily on radiological methods.
• Scintigraphy, a common method in Sweden, frequently yields inconclusive results for PE diagnosis.
• There is a need for more definitive and efficient diagnostic techniques for pulmonary embolism.

Purpose of the Study:

• To evaluate the efficacy of spiral computed tomography (CT) in diagnosing pulmonary embolism.
• To compare spiral CT with existing methods like scintigraphy for pulmonary embolism detection.
• To assess the potential of spiral CT as a primary diagnostic tool for pulmonary embolism.

Main Methods:

• Spiral computed tomography (CT) was performed with continuous infusion of contrast medium.
• The technique allows for rapid imaging, with examinations taking less than one minute.
• Pulmonary arteries are clearly depicted, with emboli identified as filling defects.

Main Results:

• Spiral CT clearly visualizes pulmonary arteries and identifies emboli as filling defects.
• The examination procedure is very rapid, taking under one minute.
• The technique has demonstrated significant potential in preliminary results.

Conclusions:

• Spiral computed tomography is a highly effective method for diagnosing pulmonary embolism.
• Its speed and clarity make it a promising alternative to traditional methods like scintigraphy.
• Spiral CT may become the method of choice for pulmonary embolism diagnosis in the future.
