Comparison of Black Hole Sign, Satellite Sign, and Iodine Sign to Predict Hematoma Expansion in Patients with Spontaneous Intracerebral Hemorrhage

Table 2

Predictive performance of hematoma predictors.

	Sensitivity (%)	Specificity (%)	PPV (%)	NPV (%)	Accuracy (%)
Black hole sign	47.5	79.3	82.9	41.8	57.8
Satellite sign	41	93.1	92.6	42.9	57.8
Iodine sign	78.7	86.2	92.3	65.8	81.1
Any NCCT sign	67.2	75.9	85.4	52.4	70

PPV: positive predictive value; NPV: negative predictive value.
