Case 5: Imaging Wisely When Evaluating for Pulmonary Embolism

Explains doses to patients and their impacted organs from CT and V/Q scans in the evaluation of pulmonary embolism.

Authors: E. Grady; F.H. Fahey

Audience: Radiologists, radiologic technologists, nuclear medicine technologists and medical physicists working in diagnostic radiology or nuclear medicine

This educational activity is free.

Objectives
Upon completion of this case, the participant will be able to:

  1. Demonstrate contributions of medical radiation to overall radiation exposure of patients and potential consequences that have been published in the medical literature
  2. Demonstrate differences in radiosensitivity of different tissues, and differences in radiosensitivity over different age groups
  3. Describe effective dose to patients from computed tomography (CT) and ventilation/perfusion (V/Q) scans in evaluation of pulmonary embolism as well as specific doses to certain tissues and the fetus
  4. Describe recent literature and selected national guidelines for evaluating pulmonary embolism in the setting of a normal chest radiograph
