    This study evaluated the feasibility of automated segmentation techniques for pituitary adenomas, pituitary gland, and internal carotid arteries using T1CE coronal MRI.

  • 2

    A cohort of 255 patients with surgically confirmed pituitary adenomas was analyzed, utilizing manual annotations by expert neurosurgeons as ground truth.

  • 3

    Swin-Unet and nnU-Net demonstrated comparable voxel-wise performance, with mean Dice similarity coefficients of 0.70 and 0.69, respectively.

  • 4

    Segmentation accuracy was lower for the pituitary gland compared to the pituitary adenoma and internal carotid arteries.

  • 5

    The mean computation time for segmentation was 78.4 seconds per patient, facilitating approximate 3D reconstructions for qualitative assessment.
