The efficacy of nuclear medicine diagnostic procedures was measured. Three levels of efficacy were defined. However, two different methods of evaluating efficacy itself were first compared. Using two methods, logistic regression and entropy-minimax pattern detection, substantial agreement was found between them in several clinical observations. (1) There are no attributes that indicate that any grouping of symptoms, signs, and laboratory findings is capable of suggesting that a patient does or does not have a pulmonary embolus. (2) The lung scan test is the only reliable method which indicates that a patient may have a pulmonary embolus or does not have a pulmonary embolus. (3) The validity of these conclusions and the ability to apply them widely to ongoing clinical practice is based on the prospective design of the Study which included an appropriate distribution of institutions by type, size, and geographic location. Also, the only judgement samples was that of the referring physician. (ERB)
