“…Optimal S3 lead implantation requires fluoroscopic guidance during surgery, while a simple and effective implantation protocol helps reduce laborious fluoroscopy exposure 14 . To explore an appropriate protocol that might be of clinical utility, we applied CT‐derived three‐dimensional volumetric model reconstruction to measure anatomic landmarks noninvasively and efficiently in a large population 17,20 . We measured anatomic measurements for the S3 foramen pertinent to SNM in 739 patients.…”

Aims: To define radiologically anatomic measurements for the S3 foramen and develop an efficient and straightforward implantation protocol for sacral neuromodulation (SNM) in a southern Chinese population. Methods: We retrospectively reviewed 793 adults without sacrococcygeal abnormalities or bony injury. We generated CT-derived three-dimensional volumetric models and collected radiologically anatomic measurements of S3 foramen. A multiple generalized linear regression model was applied to evaluate implantation protocol for SNM. Results: Height, weight, and sacral height were significantly different between enrolled patients based on sex (p < 0.001 for all), while age and sacral width were similar. The measurements L1, L2, A1, and A2 on both sides were similar, while based on sex, those of L1, A1, A2 showed significant differences [7.02 ± 0.90 (M) vs. 6.10 ± 0.99 cm (F) (p < 0.001); 83.05 ± 6.23 (M) vs. 82.08 ± 7.53°(F) (p = 0.005); and 13.31 ± 5.69 (M) vs. 11.97 ± 4.91°(F) (p < 0.001), respectively]. The multiple generalized linear regression model demonstrated that sex was a common independent factor for estimating L1, L2, A1, A2, while the consistency rate between the estimated model and actual measurements was poor. The measurements L1, L2, A1, and A2 were approximately 7.0 cm (M) versus 6.1 cm (F), 1.8 cm (M) versus 1.8 cm (F), 83°( M) versus 82°(F), and 13°(M) versus 12°(F), respectively. Conclusions: This retrospective study indicates that the radiologically anatomic measurements for the S3 foramen have unique characteristics.

“…19 Regarding to evidences based on the anatomy and anthropology sciences, the pelvimetry technique has an important role in determination of the bony pelvis diameters and estimating the pelvic diameters. 1 In this study, results of pelvimetry using CT in study population and its association with increased cesarean section rate were evaluated. In this study, the height of mothers did not match with type of delivery and pelvis dimensions.…”

Objectives The aim of this study is an anthropometric study in non-pregnant reproductive-aged women to predicting kind of delivery. Methods This study was based on the archived information of Hazrat-e Rasool university hospital on 157 generative age women from 16 to 60 years old who underwent CT between March 2015 and March 2018. Results The obtained results showed that the three conjugates on sagittal plane, transverse diameter, anteroposterior sagittal diameter, interspinous diameter, and intertuberous diameter on the coronal plane. The obstetrical conjugate was 123.3 mm in normal vaginal delivery and 113.9 mm in Cesarean section, which was slightly longer than delivery group. The mean interspinous and intertuberous diameters measured by CT scans were 105.0 and 107.4 mm. Conclusion The results of our study showed that because of the reduction in diameter of the inlet and middle pelvis, the rate of cesarean section was higher in females under 35 years ages.

“…The helical acquisitions provided reliable measurements of pelvic diameters: the promonto-retro-pubic diameter, the transverse median and bi-spinous diameters. Magnetic resonance imaging (MRI) is a non-irradiating imaging technique that also yields reliable pelvic measurements [7], and although it seems to be a good alternative, the use of MRI remains limited by availability issues [8].…”

Background: CT in pregnant patients requires careful consideration of the radiation dose and corresponding radiation risks from ionizing radiation to the unborn child. The determination of foetal dose in diagnostic radiology is of interest as a basis for risk estimates from medical exposure of the pregnant patient. Objective: To evaluate the foetal-maternal radiation doses delivered during the CT-Pelvimetry procedure and to estimate the risk to the unborn child to develop a cancer in childhood and hereditary disease. Materials and Methods: We investigate the foetal-maternal radiation doses during CT-scan Pelvimetry in Douala (Cameroon). Data of 194 helical acquisition CT-Pelvimetry were collected between May 2017 and May 2019. An average DLP for the examination was established and the average effective dose was evaluated. The fetal dose was calculated and the FetDose V5 program was used for risk estimations. Results: The average dose length product (DLP) was 56.17 mGy·cm (range: 51.69 -59.21 mGy·cm). The average effective dose received by women pregnant was 0.78 mSv. The mean individual fetal dose was 1.5 mGy (range: 0.76 -1.87 mGy). The risk of Childhood Cancer calculated was: range 1 in 16,000 to 1 in 10,000 and 1 in 260,000 to 1 in 106,000 to the risk of Hereditary Disease, respectively. Conclusion: This study shows that the foetal-maternal doses delivered during CT-Pelvimetry examinations are very low and the risks of childhood cancers and hereditary diseases are derisory, the technology

Can three-dimensional pelvimetry using low-dose stereoradiography replace low-dose CT pelvimetry?

Abstract: Pelvic inlet measurements using SRI are reliable. Compared to CT pelvimetry, SRI leads to a significant decrease in fetal and maternal radiation doses. These findings should prompt physicians to use SRI as the first-line approach for pelvimetry.
