title: Head injury: correlation of brain morphology on cranial CT with head injury severity using a new (computed tomography-head injury severity assessment) grading scale--a pilot study.
abstract: Eighty two (82) consecutive patients who presented with mechanical brain injury to the Accident and Emergency department of our hospital and were assessed with cranial Computerized Tomographic Scan between November 2005 and April 2006 were included in the study. Demographic data were obtained at admission. Clinical severity of head injury was assessed by the Glasgow Coma Scale Score just before cranial CT while morphologic severity was assessed using features on the same post-resuscitation cranial CTwith which theTCDB (Traumatic Coma Databank) grade and CT-HISAS (computerizedTomographic-Head injury Severity Assessment Scale) score were assessed. Both the TCDB and CT-HISAS scores were correlated with short-term outcomes using the Glasgow outcome score. Pearson's correlation coefficient, ANOVA and regression models were used as appropriate for statistical tests of significance.The age range of Patients was between 3 months and 86 years with a mean of 26.8 years and median of 25.9 years +/- 1.9 years (95% CL). There were more males (74.4%) than females (25.6%). There was a negative correlation between Post resuscitation GCS and CT-HISA score (p = -0.0141). However, although patients with non-functional outcome based on Glasgow Outcome score had higher CT-HISA scores, this relationship was not statistically significant. From our study, brain morphology on cranial CT using the CT-HISA Scale predicts clinical severity and outcome.We believe this study that CT-HISA may find useful application in assessment of teleradiologically transferred CT images of patients as well as research in mechanical brain trauma.
