The Diagnostic Ability of rs-DWI to Detect Subtle Acute Infarction Lesion in the Different Regions of the Brain and the Comparison between Different b-Values

Table 3

Statistical analysis of the diagnostic ability between ss-DWI and rs-DWI in the whole brain.

Sequence	Results				P-Value (McNemars)	Statistical Analysis (%)
	True Positive	True Negative	False Positive	False Negative		Sensitivity	Specificity	PPV	NPV
rs-DWI	385	19	1	1	P=1	99.7	95	99.7	95
ss-DWI	318	0	20	68	P≤0.001	82.38	0	94	0

ss-DWI: single shot-Diffusion Weighted Imaging; rs-DWI: readout segment-Diffusion Weighted Imaging; PPV: positive predictive value; NPV: negative predictive value.
