Low-dose 3D CT can be used for estimating pelvimetry parameters:[1]
| Parameter | Image (maximum intensity projection) |
Definition | Normal measures | |
|---|---|---|---|---|
| Pelvic inlet | Transverse diameter of the pelvic inlet | 170px | 13 to 14.5 cm.[1] | |
| Obstetric conjugate | 120px Median plane |
The line between the narrowest bony points formed by the sacral promontory and the inner pubic arch | 10 to 12 cm.[1] | |
| Interspinous distance | 170px | The line between the narrowest bone points connects the ischial spines | 9.5 to 11.5 cm.[2] | |
| Pelvic outlet | Sagittal pelvic outlet diameter¨ | 120px | 9.5 to 11.5 cm.[2] | |
| Intertuberous diameter | 150px | 10 to 12 cm.[2] | ||
