(15) The radionuclide quantitative method was a more sensitive means of detecting early cases of mismatched pulmonary blood flow than roentgenography, which was nonquantitative and required the presence of relatively gross perfusion abnormalities before visual perception was possible.
(16) This study shows that enzyme histochemistry provides nonquantitative methods to detect and localize microvascular injury and that the injury caused by the microvascular clips was mild and reversible.

(20) Quantitative nuclear cardiography may help to fill the gap between the nonquantitative, rather unspecific and the specific but invasive methods of cardiologic investigation.
Qualitative
Definition:
(a.) Relating to quality; having the character of quality.
Example Sentences:
