“Medical imaging” is a decidedly unglamorous phrase. Yet the technology it refers to—the ability to peer inside the human body without having to cut that body open—represents one of the greatest achievements in history. In this provocative book, the authors examine the advent of imaging in its myriad forms (X-ray, ultrasound, CT scan, etc.) and how it is transforming both the practice and the business of medicine.

And, make no mistake about the “business” part. With a staggering 687 million imaging procedures performed in the U.S. each year, at an annual cost of $170 billion, imaging has become a key medical profit center.

Jeff and co-author Bruce Hillman chart the complex forces driving the phenomenal growth of imaging, from arcane Medicare rules to self-interested physicians (some of whom earn lucrative fees for sending patients to the scanner) to the fear of malpractice lawsuits. But the real culprit, they conclude, is more fundamental: our collective discomfort with ambiguity, or as the authors put it, “the impossible quest for medical certainty.”

The book abounds with fascinating historical anecdotes. You probably remember (at least the fuzzy outlines of) Wilhelm Röntgen’s remarkable discovery of X-rays in 1895. But did you know that the Beatles were indirectly responsible for the first CT scanner? (Flush with cash, their label EMI backed an unlikely innovator, whose primitive equipment required nine hours to make a scan.)

The book’s real contribution, however, is its careful examination of the conflicts this amazing technology has generated. Some of these conflicts, such as the turf war between radiologists and oncologists, are primarily of interest to specialists. Others, such as the debate over using CT scans to screen smokers for lung cancer, illuminate the twisted workings of modern medicine.
