CT pelvimetry

ABSTRACT

Because of the possible oncogenic hazards of foetal irradiation, this study have investigated the feasibility of replacing the conventional method with low-dose digital radiographs [DR] generated on a CT scanner [DR pelvimetry]. This study included 20 full-term pregnant female. All of them were examined by CT pelvimetry [AP. Tr. an conjugate diameters] and ultrasonic assessment of BPD, AC and the expected foetal weight besides the mode of delivery were reported. The results showed that; 12 cases were delivered spontanously vaginally, 2 cases assisted vaginal delivery, and 4 cases delivered by C.S. due to CPD. The last two cases were delivered by C.S. due to foetal distress. From this study it appeared that, when only one diameter is short and the other diameters are normal provided that foetal measurements are within the average; vaginal delivery without mechanical assistance is expected
