Overview Brief

Do you need to undergo a CT Angio- Pulmonary Embolism? Read on to know all about it.

What is CT Angio- Pulmonary Embolism?

CT Angio- Pulmonary Embolism is a diagnostic test that makes use of contrast material to generate images of the arteries to detect a pulmonary embolism.

The CT Angio- Pulmonary Embolism procedure makes use of a CT (Computed Tomography) scanner to generate high-resolution images using an iodine-rich contrast chemical that is injected into the patient [1]. The procedure is a minimally invasive one as it only requires one intravenous line, and is hence the preferred method of detecting pulmonary embolism.

How is CT Angio- Pulmonary Embolism performed?

CT Angio- Pulmonary Embolism is conducted in an exam room where the CT scanner is present.

  • The patient lies on the examination table and the contrast material is injected.
  • The table is then moved into the scanner, where rotating X-ray beams and X-ray detectors together detect the flow of contrast material through the body [2].
  • A computer program translates this data into two-dimensional images that are presented on a computer in a separate control room.
  • Following the exam, a bandage will be placed over the injection site.

Side effects/risks of CT Angio- Pulmonary Embolism

While CT Angio- Pulmonary Embolism is a safe procedure, possible risks and side effects include:

  • Allergic reactions to the contrast material.
  • Adverse effect of radiation on foetuses in pregnant women.
  • Minor risk of radiation exposure during the scan.

Preparations before performing CT Angio- Pulmonary Embolism

The following preparations will ensure that CT Angio- Pulmonary Embolism happens safely.

  • Patients are asked not to eat or drink for several hours before the procedure.
  • All metal objects must be removed.
  • Pregnant women should inform their physicians so that preparations can be made to reduce radiation levels.

Post-care after CT Angio- Pulmonary Embolism

No special post-care is required after CT Angio- Pulmonary Embolism. The results will be shared by the physician within a few days.
