Fig. 4From: Ventricular apparent diffusion coefficient measurements in patients with neoplastic leptomeningeal diseaseROC curve from ADC values obtained from the mid body of the lateral ventricles. In the mid body of the right lateral ventricle the AUC was 0.69 (95% CI 0.57–0.81) with an optimal cut off point of 3.22 × 10− 9 m2/s. In the mid body of left lateral ventricle the AUC was 0.7 (95% CI 0.58–0.82) with an optimal cut off point of 3.23 × 10− 9 m2/s. Using an average value of HU measurements in the lateral ventricles the AUC was 0.73 (95% CI 0.61–0.84) with an optimal cut off point of 3.11 × 10− 9 m2/s (0.78, 0.65)Back to article page
