Evaluation of Radiation Dose and Image Quality in the Transition from Conventional Pelvimetry to Low-Dose Helical CT Pelvimetry [PDF]

Tomography
Purpose: The present study aimed to assess the radiation dose associated with low-dose (LD) CT pelvimetry compared with conventional radiography and to evaluate the adequacy of the resulting image quality.

Diagnostic Value of Clinical Pelvimetry and Sonopelvimetry in Determining Mode of Delivery in Nulliparous Women [PDF]

Advanced Biomedical Research
Background: Normal morphological features of the maternal pelvis are important prerequisites for vaginal delivery. Clinical pelvimetry and sonopelvimetry are inexpensive methods of assessing pelvic capacity.

Three-dimensional visualization of the total mesorectal excision plane for dissection in rectal cancer surgery and its ability to predict surgical difficulty [PDF]

Scientific Reports, 2023
Total mesorectal excision (TME) for rectal cancer is often technically challenging. We aimed to develop a method for three-dimensional (3D) visualization of the TME dissection plane and to evaluate its ability to predict surgical difficulty.

MRI-based pseudo-CT sequences as a radiation-free alternative to CT for obstetric pelvimetry: a proof-of-concept study [PDF]

European Radiology Experimental
Background Pelvimetry is essential in obstetrics for delivery planning. While computed tomography (CT) is the standard, magnetic resonance imaging (MRI) offers a radiation-free alternative with zero echo time (ZTE) and black bone (BB) sequences providing

Intra- and inter-rater reliability in a comparative study of cross-sectional and spiral computed tomography pelvimetry methods

Acta Radiologica Open, 2019
Background Different low-dose computed tomography (CT) pelvimetry methods can be used to evaluate the size of birth canal before delivery. CT pelvimetry might generate an acceptable low fetal radiation dose but its measurement accuracy is unknown ...

Late gestation MRI to assess maternal pelvimetry, fetal biometry and placental oxygenation: a retrospective pilot study [PDF]

BMC Pregnancy and Childbirth
Background The role of MRI pelvimetry and fetal size estimation in predicting mode of birth and risk of operative birth have been studied. However, there are no complete MRI studies that assess the maternal pelvis, fetal dimensions, and the placenta in a
