Highlights
- •The CSF cleft is more prominent on ADC map than on T2WI.
- •Diagnostic performance of CSF cleft is increased when ADC and T2WI are used together.
- •ADC map might be helpful in tumor localization as well as tumor characterization.
Abstract
We investigated whether the CSF cleft sign on ADC maps is beneficial for differentiating
extra-axial tumors from intra-axial tumors. Seventy-seven intracranial tumor patients
were reviewed. Visual grades of CSF cleft sign on T2WI and ADC were compared. The
diagnostic performance of CSF cleft sign using ADC plus T2WI was compared with that
using T2WI alone. A CSF cleft was more easily visualized on ADC (P < 0.01). The diagnostic performance of CSF cleft sign significantly increased in accuracy
of 85.7 to 96.1% (P < 0.01) when ADC and T2WI were used together.
