Abstract

Non contrast-enhanced CT scan (NCCT) with subsequent contrast-enhanced CT scan (CECT) are routinely practised in cases of brain tumors. For brain metastases, we observed that the lesions were better demonstrated on CECT and no useful information was obtained on NCCT. We reviewed 58 CT brain of 54 cancer patients who suspected to have brain matastases. We found that 24 cases (40%) had brain metastases. Of these, CECT demonstrated the lesions better than NCCT in 10 cases (42%) ,;CECT and NCCT were equally good in demonstration of the lesions in 12 cases (50%). The remaining two cases were difficult to compare because of too numerous lesions. Two false negative results were also found on NCCT. These findings suggested that NCCT was unnecessary. Elimination of NCCT would be more cost-effective, reduce examination time and radiation exposure.
