Pulmonary embolism with Dual Energy LungPBV

Tips and tricks

1. As the FOV is limited to 26 cm due to the smaller detector of the B-system, it is very important to place the patient centrally in the scan field to cover as much lung parenchyma as possible. Use a lateral and top topogram for that.
2. Taller patients show increased image noise. To achieve optimal results for CTA and iodine distribution map limit the use of this protocol to patients with a body weight of < 90 kg.
3. As the color-coded iodine distribution map is very sensitive to beam hardening artifacts arising from dense contrast material in the subclavian vein and superior vena cava, use a caudocranial scan direction and flush the venous system well with a saline bolus after the injection of contrast.
