  • Title: [Pelvimetry by digitalized radiography].
    Author: Adam P, Alberge Y, Sablayrolles JL, Grandjean B.
    Journal: J Radiol; 1986 Jan; 67(1):47-52. PubMed ID: 3701674.
    Abstract:
    We studied the ability of digital radiographs generated on a computed tomography scanner to replace conventional pelvimetry. Two digital radiograph's and one CT section permit us to measure the maternal pelvis. The anteroposterior digital radiograph allows measurement of the maximum transverse and median transverse diameters of the pelvic inlet. These two distances are corrected for magnification after reference to the lateral digital radiograph and to a graph determined owing to a phantom. The anteroposterior digital radiograph also permits to perform a CT section passing through the ischial spines with direct measurement of the inter spinous diameter. The lateral digital radiograph gives us the true values for the anteroposterior diameter of the pelvic inlet, the low sagittal diameter, the cord and the rise of the sacrum. The dosimetry studies demonstrated that maternal skin doses and fetal gonad doses were very low. Pelvimetry using digital radiography is a simple and rapid to perform procedure which offers the advantage of low radiation exposure to both fetus and mother and a high accuracy of measurement.
