It almost completely dilutes the contrast agent coming from the superior vena cava SVC. Previous Article CV2i Editorial board. Over-diagnosis may also result in treatments that might be dangerous for the unborn child and the mother.

With a mortality rate at approximately 25 percent, pulmonary embolism PE is one of the leading causes of maternal death during pregnancy and postpartum. Prohibition of deep inspiration to prevent the Valsalva Maneuver, low voltage scan, appropriate pulmnoaire volume and rate, and early acquisition.

Outline Masquer le plan. As evidenced in the literature, CTPA in pregnant women tends to produce images of pulmoniare quality with weaker contrast enhancement compared with scans of non-pregnant patients. Ann Fr Anesth Reanim. Quality of CT pulmonary angiography for suspected pulmonary embolus in pregnancy. Pulmonary CT angiography protocol adapted to the hemodynamic effects of pregnancy.


It is important to carefully examine pulmonary angiographies in search of cardiac abnormalities that can cause chest symptoms unrelated to pulmonary embolism. Image quality and radiation exposure at pulmonary CT angiography with or kVp protocol: The researchers identified four fundamental factors that could improve contrast enhancement of the pulmonary arteries during CT angiography in pregnant women: Results showed that very few institutions had a specific protocol and levels of satisfaction varied widely.

Pulmonxire has potential to help reduce mortality rates and achieve better outcomes.

Conversely, when voltage is increased, the dominant Compton Effect reduces contrast. Lastly, conventional imaging modalities are more complicated when used for pregnant patients.

This reduced quality of CTPA in pregnant women is caused almost entirely by pregnancy related physiological changes that can last for several weeks postpartum. Baccouche abJ. Moreover, foetuses are especially sensitive to dose.
