Number	56 patients and 128 vertebrae	54 patients and 102 vertebrae
Location	Cervical – 10, Dorsal – 57, Lumbar – 61	Cervical – 9, Dorsal – 52, Lumbar – 41
Final diagnosis	All were TB vertebrae	Out of 102 vertebrae, 48 were finally metastatic and 54 were finally TB.
ADC values	Mean – 1.4 ± 0.20 × 10−3 mm2/s	12 metastatic vertebrae reported as TB vertebrae (False +ve) had ADC values from 1.2 to 1.40 × 10−3 mm2/s
		19 TB vertebrae reported as metastatic had ADC values from (False −ve) - 0.86 to 1.0 × 10−3 mm2/s
		35 TB vertebrae (True +ve) - 1.4 ± 0.20 × 10−3 mm2/s
		36 metastatic vertebrae (True −ve) - 0.83 to 1.0 × 10−3 mm2/s
