to restoring csf flow it has been discovered that the methods disclosed herein are superior in accounting for anatomic variations that frequently occur and would given rise to a different correction factor if derived using the standard method atlas orthogonal technique from a conventional x ray radiograph however owing to the scarcity and resource cost of upright mri equipment it is believed that correction calculation and method of the y component of the correction vector can be made from x ray radiographs of clinically less challenging patients with satisfactory results accordingly in the interest of providing patient with cost effective follow up care it is desirable to calculate the correction vector coordinates from both x ray radiographs and mri slices to determine the variance so that future corrections of the patient can be made from future x rays by comparison to the initial x ray so the practitioner can make a clinical judgment as to whether to apply the same variance to correct the subsequent x ray can we provide an example of this variance in clinical application of the above methods patients were examined in an upright mri utilizing cerebral spinal fluid csf flow cine software which allowed for evaluation of csf flow it was noted that in each patient there was a static misalignment of the 1st cervical vertebra atlas as well as substantially reduced csf flow at the cranio cervical junction associated with cerebellar tonsillar ectopia both patients received a manipulation directed at the.
