METHOD FOR DETERMINING AXIAL VERTEBRAL COLUMN UNLOADING TIME IN TREATING CHILDREN ON ACCOUNT OF NONCOMPLICATED VERTEBRAL BODY COMPRESSION FRACTURES Russian patent published in 2005 - IPC

FIELD: medicine.

SUBSTANCE: method involves determining injured vertebra body contrast on sagittal T2-weighted magnetic resonance tomogram using a formula of C=(I_a+I_b)/(I_a+I_b). Axial unloading time corresponding to vertebra body marrow edema duration is determining from formula T=C/In_c. Daily contrast drop index In_c is taken to be equal to 0.0025 in superior thoracic vertebra cases. The value is equal to 0.0023 in medial thoracic vertebra cases and to 0.0022 in inferior thoracic vertebra cases. C is the injured vertebra contrast; I_a is the injured vertebra body signal intensity; I_b is the adjacent intact vertebra body signal intensity; T is the vertebral column axial unloading time corresponding to vertebra body marrow edema duration; In_c is the daily injured vertebra contrast drop index.

EFFECT: high accuracy in determining axial unloading time.
