Feasibility of sentinel lymph node biopsy in breast cancer patients clinically suspected of axillary lymph node metastasis on preoperative imaging

Table 4 Diagnostic accuracy of imaging techniques in staging axillary nodes

	Sensitivity (%)	Specificity (%)	PPV (%)	NPV (%)	Accuracy (%)
US	59.88	82.09	58.14	83.12	75.57
MRI	61.73	78.24	54.35	82.97	73.36
PET-CT	62.41	82.96	65.67	80.87	75.91
SI^*	82.14	45.91	38.76	86.05	56.57

^*SI are patients in whom a preoperative imaging technique, including breast ultrasound (US), contrast-enhanced magnetic resonance imaging (MRI), and positron emission tomography (PET)-CT scanning, revealed suspected axillary LN metastasis. PPV, positive predictive value; NPV, negative predictive value.
