Popis: Spinal cord inflammation and atrophy contribute to debilitating symptoms in HAM/TSP. We have developed a robust and fast algorithm to determine average cross-sectional area in cervical (c-spine) and thoracic (t-spine) spinal cords by tracing contours perpendicular to the edge in T1-weighted MRI images. The cross-sectional areas in the c- and t-spines were determined in 25 HAM/TSP, 10 asymptomatic carriers (AC) and 10 healthy volunteer (HV) subjects. To date, we have followed 8 of the HAM/TSP patients longitudinally over a two-year period. When compared to the HV data, the HAM/TSP spinal cord profiles fell into four general categories: atrophic entire spine (48%), atrophic t-spine (32%), atrophic c-spine (8%), and normal (12%). The majority of ACs had similar spinal cord profiles to those in the HV group, however, 3 ACs showed a pattern similar to HAM/TSP. As a group, both HAM/TSP c- and t-spines were significantly lower than those of HV (p
