Abstract: Objective   To provide further anatomical basis for lumbar vertebra operations by measuring anatomical parameters of lumbar vertebra basivertebral foramen (BF) based on sagittal MRI images.  Methods  Sagittal MRI images of 172 vertebral bodies of 43 adult patients admitted to the First Affiliated Hospital of Guangzhou University of Chinese Medicine and Dongguan Hospital of Guangzhou University of Chinese Medicine from February 2018 to December 2022 were retrospectively analyzed. The PACS imaging system was used to measure the BF depth (BFD), BF height (BFH), Vertebral width (VW), the upper end of BF between the upper boundary and the endplate (VH1), the lower end of BF between the lower boundary and the endplate (VH2), and calculate the ratio of BFD to vertebral body width (BFD/VW) and the ratio of BFH to vertebral body height (BFH/VH).   Results   After comparing lumbar vertebrae, the STIR sequence showed that BFD (3.93±1.58mm) of L1 vertebrae was lower than BFD of L3 (5.26±2.34) mm and BFD of L4 (5.82±2.99) mm,which was statistically significant (P<0.05). Also in the STIR sequence, BFD/VW of L1(0.12±0.05) was lower than that of BFD/VW of L4(0.17±0.09) (P<0.05). Moreover, there were statistical differences in the comparison of BFD/VW in L1-L4 among the four groups (P<0.05). There was no statistical significance in the BFH/VH of each vertebral body (P>0.05). In the comparison between male and female, BFH of male L3(7.95±2.84) mm was higher than that of female L3(6.30±1.93) mm on T2WI, which was statistically significant (P<0.05). With the increasing of the vertebrae sequence, BFD showed a gradually increasing trend, and it was more obvious in the STIR sequence. BFH had no obvious fluctuation with the increasing of vertebral body sequence.    Conclusions   STIR sequence in sagittal MRI image can be used as the clinical measurement standard of BF in middle-aged and elderly patients, which providing anatomical reference for the selection of lumbar surgical treatment.
