Ct And Mr Evaluation Of The Pregnant Patient Fetal And Matern Use of ct and associated contrast material should not be withheld if clinically indicated, but a thorough discussion of risks and benefits should take place 8. in the evaluation for acute processes such as appendicitis or small bowel obstruction, the maternal benefit from early and accurate diagnosis may out weigh the theoretical fetal risks. Trauma. us may be sufficient for the initial imaging evaluation of a pregnant patient who has sustained trauma, but ct should be performed if serious injury is suspected. all patients undergoing ct of the abdomen or pelvis during pregnancy should sign the written informed consent form available at (consent form). the consent form can be.
Ct And Mri In Pregnancy And Lactation Fergus As use of imaging in the evaluation of pregnant and lactating patients continues to increase, misperceptions of radiation and safety risks have proliferated, which has led to often unwarranted concerns among patients and clinicians. when radiologic examinations are appropriately used, the benefits derived from the information gained usually outweigh the risks. this review describes. The use of other imaging modalities—such as plain radiography, computed tomography (ct), and magnetic resonance imaging (mri)—in pregnancy is increasing. 1 imaging plays an important role in the investigation of many conditions in pregnancy, but also has potential to cause harm. concerns about harm to the fetus and mother can make decisions. Ct scanning of a pregnant patient is often a source of distress for both patient and staff. despite having expertise in image interpretation, a radiologist may not feel equipped to discuss the radiation related safety issues during ct scanning of the fetus. in addition, patients are frequently concerned about the risk of adverse effects on the fetus from exposure to ionizing radiation. Objective. diagnostic imaging performed during pregnancy, particularly if it involves the use of ionizing radiation, can be a source of great anxiety for both health care providers and patients. especially with the growing public awareness of the increasing radiation from medical imaging, including ct, it is important to have a contemporary policy for imaging evaluation in the pregnant or.

Diagnostic work up of common clinical situations during pregnancy, with respect to maternal and fetal safety6.1. non obstetrical emergency situations6.1.1. trauma. traumatic injuries are the leading non obstetric cause of maternal death [13], [78], [79]. after trauma, there is an urgent need for quick and accurate imaging of the mother and. The mean fetal dose of single phase abdominopelvic ct is approximately 20 mgy and is seldom higher than 50 mgy unless multiple phases are used. for most patients, the fetal dose is lower than the thresholds for tissue effects. accurate input measurements (eg, maternal circumference) improve fetal dose estimation.
