Determination of normal lumber spinal canal dimension using magnetic resonance imaging

Abstract

This an analytical study aimed to determine and measure the normal dimension range of lumber spinal canal in Sudanese population by using magnetic resonance imaging in order to assess the normal variant between the Sudanese population. The study found that the longest mean AP diameter was ay L1 (17.9 ± 2.0mm) in male while (17.9± 2.7) in female. The shortest mean AP diameter was at S1 (15.9± 3.3) in male and (15.5 ±3.1) in female. The AP diameter gradually decreased from L1 to S1 . There was no significant statistical difference between both gender. There were significant statistical differences exist between AP canal diameter with age and weight of the study sample. This standardization measurement was made at level L1 to S1, The technologist should know the normal range of spinal canal diameter by seminars and training to correct image interpretation.
