Cerebral infarction vs. intracranial hemorrhage--validity of clinical diagnosis.

In aim to improve the validity of clinical diagnosis of acute supratentorial ischemic cerebral infarction vs. intracranial hemorrhage, two different scoring systems were analyzed, each separately and combined, on one hundred eighty-eight patients sample. Results suggested higher sensitivity and positive predictive value for Guy's Hospital score, giving it higher importance in detection of hemorrhage, while combined application of both systems, in cases with identical findings, provided sensitivity 0.95 and 0.92 negative predictive value, in certain diagnosis category. A review of complete results disclosed that application of both systems separately didn't provide satisfactory diagnostic gain in differential diagnosis of that syndrome on our sample, while combined application provided high level of accuracy, eliminating simultaneously a significant proportion of patients (43.62%), as a category of uncertain diagnosis.
