The Diagnostic Value of ¹⁸F-FDG PET/CT Bone Marrow Uptake Pattern in Detecting Bone Marrow Involvement in Pediatric Neuroblastoma Patients

Table 3

BMI positive patients, BMI negative patients, PPV, NPV, sensitivity and specificity of four tests.

	BMI positive	BMI negative	PPV (%)	NPV (%)	Sensitivity (%)	Specificity (%)
PET/CT	70	28	92.9	92.9	97.0	83.9
BMB	41	57	100.0	54.4	61.2	100.0
PHOX2B of blood	48	50	95.8	58.0	68.7	93.5
PHOX2B of BM	62	36	96.7	80.6	89.6	93.5

BMI: bone marrow involvement, BMB: bone marrow biopsy, PHOX2B of blood: paired-like homeobox 2b of blood, PHOX2B of BM: paired-like homeobox 2b of bone marrow, PPV: positive predictive value, and NPV: negative predictive value.
