Comparing sensitivity, specificity, accuracy between two different diagnostic tests used on the same group of patients

[Pete12321]

Dear all

Could someone advice on how I should go about comparing the sensitivity, specificity, accuracy between two different diagnostic tests used on the same group of patients on SPSS?
ie:
sensitivity (test 1, test 2, p-value)
specificity (test 1, test 2, p-value)
accuracy (test 1, test 2, p-value)
positive predictive value (test 1, test 2, p-value)
negative predictive value (test 1, test 2, p-value)

where test 1 is ultrasound and test 2 is X-ray

Thanks
