Radiation doses in low-dose pelvimetry using rare-earth screens

Area of Science:

• Radiology
• Medical Physics
• Obstetrics

Background:

• Obstetric pelvimetry is crucial for assessing pelvic dimensions during pregnancy.
• Traditional methods may involve significant radiation doses.
• Minimizing radiation exposure is paramount in obstetric imaging.

Purpose of the Study:

• To evaluate a novel low-dose technique for obstetric pelvimetry.
• To quantify radiation doses to maternal and fetal gonads using this technique.
• To assess the associated risks of hereditary ill health and leukemia induction.

Main Methods:

• Implementation of a low-dose technique utilizing rare-earth screens.
• Reduction of image quality parameters to minimize radiation exposure.
• Estimation of absorbed doses to maternal and fetal gonads.

Main Results:

• Estimated absorbed dose to maternal gonads: 0.9 mGy.
• Estimated absorbed dose to fetal gonads: 0.01 mGy.
• Calculated risks for hereditary ill health and leukemia induction were found to be very low.

Conclusions:

• The low-dose obstetric pelvimetry technique is effective in minimizing radiation exposure.
• This technique offers a favorable risk-benefit profile for pregnant individuals and fetuses.
• Further adoption of this method can enhance radiation safety in obstetric diagnostics.
