Abstract first measured on plain skull images. At present, evaluation of the brain and skull more commonly involves CT and MR imaging. We evaluated a new MR imaging method of evaluating platybasia. METHODS: We retrospectively evaluated midline sagittal MR images in 200 adults and 50 children. The basal angle of the skull base was measured by using two methods: The standard MR imaging technique measured the angle formed by two lines—one joining the nasion and the center of the pituitary fossa connected by a line joining the anterior border of the foramen magnum and center of the pituitary fossa. The modified technique measured the angle formed by a line across the anterior cranial fossa and dorsum sellae connecting a line along the clivus. RESULTS: With the standard MR imaging technique, we obtained mean angles of 129 ° 6° for adults and 127 ° 5 ° for children, compared with 135.3 ° (composite mean) in previous series. The modified technique produced values of 117 ° 6 ° for adults and 114 ° 5 ° for children, which were significantly lower that those of standard MR imaging and traditional radiography (P <.05). CONCLUSION: Both the standard and modified MR imaging techniques produced basal
