Radiology, like any medical field, is not perfect and has it's own set of issues. Midlevels reading diagnostic imaging studies is not one of them. The biggest issue I think is consolidation by Wall Street firms. Sure, to a lesser extent, there are erosions at the margins because other fields want to do their own imaging. Cardiology took over much of cardiac imaging from radiology. OB started to read fetal US (although lots are still read by radiology including me unfortunately). ED has their FAST US exams. US machines are common in doctor offices or even handheld. However, the great thing about radiology is that it is innovative. What did radiology do to replace the significant loss of cardiac imaging? Better CT and US. MRI. Breast tomosynthesis. US elastrography. Theranostics. Etc. If radiology was like pathology, we would only be doing x-rays and slinging barium and our job market and incomes would reflect that. However, the constant pushing the boundaries and developing innovations mean that imaging has basically replaced the physical exam in this country (practically everyone gets some imaging when they go to the hospital). This has created lots of demand for radiologists. The current hot job market and high salaries are reflections of this. Plus, the increased use of clueless midlevels who use radiology as a crutch is driving up imaging demand. Personally, I don't care so much if other fields or even midlevels read their own imaging as long as my name is not attached to their reports. Nobody hides behind my license and most physicians feel this way.
I'm not sure why some folks insist that the "team" business model where many midlevels to one doc is inevitable in radiology. There are fundamental differences in the business models between diagnostic fields like radiology and pathology where the "buck stops here" and clinicians are looking for definitive answers versus clinical fields like primary care and ED. I and other posters have described many already. If the same business model could be imposed on radiology, don't you think it would have already happened? The fact that you very rarely see a midlevel reading diagnostic imaging studies with supervision except in some academic departments should tell you how well the model works in the real world. The only time you really see midlevels in radiology is they help with the scutwork and low-end procedures like para, thora, LP, PICC, etc. They're not doing embolizations, cryoablations, or TIPS independently. In my group, we don't even use a midlevel to sling barium. We use a tech who has been trained to sling barium but we dictate the reports.
For the sake of argument, let's play devil's advocate and say that you impose such a business model on radiology. What would happen? As some have suggested, you can't "triage" exams where you give the easy exams to the midlevels and the radiologist takes the hard ones. Each exam is a potential ticking legal timebomb. A new 3 mm grouping of pleomorphic calcifications or spiculated mass on a mammogram may be the only early sign of breast cancer. Here are two examples of "easy" exams that ended in multimillion dollar lawsuits.
A Charleston County jury has awarded a near $7 million verdict to a terminal breast cancer patient and her husband after a misdiagnosis from a doctor years earlier led the

A jury has awarded $16.7 million to the daughter of a Boston woman who died of lung cancer after a Brigham and Women’s Hospital radiologist missed evidence of the cancer in a chest X-ray. The verdict is the largest this year in a medical malpractice case in Massachusetts.

The first is a missed breast cancer on a screening mammogram. The second is a missed lung cancer on a chest x-ray. In both examples, the radiologists probably spent 1 minute or less on the exams and now they have this black mark of multimillion lawsuits on their records that they have to now report whenever they renew their privileges or licenses. These are typical lawsuits that I get called to be expert witness for.
On average, a radiologist in private practice reads 80-120 exams per day, depending on how busy that practice is. So a typical radiologist reads around 500 exams per week or 2000 per month. If as some have suggested that the radiologist only reviews 10-20% and then blindly signs the rest, that leaves more than a thousand exams per month that the radiologist does not review. How many misses will the midlevel make and the radiologist not catch because they didn't review the images? Some of those misses will result in some patient permanently and severely being injured or even death. The miss can easily be traced back to the original images and report. Remember images do not change and can be kept forever. What will your defense in court be? "Your honor, my midlevel missed it not me. I didn't even review the images myself even though my name is on the report." Your miss will be magnified and projected on the big screen in court. After that court case, your next stop will be in front of the state medical board and you begging them to not revoke your license. How many radiologists would agree to work in such a group and risk their careers? It's not worth it.
The lack of significant midlevel penetration in radiology has nothing to do with specialty cohesiveness or collusion among radiologists. Like most people, radiologists are primarily looking out for themselves and how can they make the most money and work the least. Radiologists are not even looking out for each other. The lack of significant midlevel penetration in radiology is due to the business model, medicolegal landscape, market forces, etc. There would need to be significant structural changes to the business model and medicolegal regulations before you will start seeing midlevels putting out reports independently in diagnostic fields like radiology and pathology.
But let's say the group is really unscrupulous and demands their radiologists blindly sign off on midlevel reports anyways without giving them the time to review images because the group really wants to make as much $$$ as possible. As I pointed out, this is fraud and people have gone to prison for this. I would be racing to be the first person in that group to file a whistleblower complaint with the federal government. This would be my ticket to an early and rich retirement! Whistleblowers have been awarded millions and tens of millions in these lawsuits, more than anything you can make in medicine.
A whistleblower reward can be very significant. We have helped clients recover millions. Call us for a free and confidential consultation.

"The amount of a whistleblower reward depends on how much money the government recovers as a result of the whistleblower lawsuit. A whistleblower who files a successful claim is paid a reward that equals between 15% and 25% of the amount recovered by the government if the government joined in the case prior to settlement or trial. If the government does not join in the case, and the whistleblower and his or her attorney pursue it on their own, the whistleblower can receive up to 30% of the total amount recovered."
