So, pick the 2 (out-of-36) that did better than a solo radiologist & run them everywhere, at nearly zero marginal cost. Also check if ensembles of the lesser-performing systems (with other systems or with radiologists) can do better, and whether any of the systems can rapid-classify 'easy cases' so expensive radiologists need only check the tougher ones.
