Sensitivity and specificity are interrelated. Increased sensitivity (I.e. in CTPA) often leads to over diagnosis and bad outcomes. We don’t routinely look at all three planes because most imaging and size criteria were developed and validated on axial sections (I.e. RECIST). Research done on volumetric measurements is in its infancy and of questionable added benefit. Show me an example where sensitivity is a problem in modern day radiology and I might buy this argument. Otherwise this is a solution in search of a problem One thing engineers often don’t appreciate about medical interpretation is that you may THINK you’ve designed a better wheel but unless you can show better OUTCOMES (not increased detection) this is probably irrelevant.
