Agreed. I think the article and parent comment seem to be from the perspective of someone who has never had to, say, read or interpret a chest CT. Or had to tell someone that they have an indeterminate module that may be cancer but may be nothing.

The article also seems to imply that their is one entity or person who controls all aspects of diagnosis (hence the meme at the top), from taking a history and doing a physical exam to perfectly understanding the intricacies of all additional diagnostic testing. Of course, your primary care doctor may not understand exactly what percentage of people in a low (or high) risk cohort with this lung nodule with certain specific imaging features turn out to have cancer. Hopefully the radiologist does—but they didn’t talk with the patient to assess their risk tolerance and data-collection preferences before saying “consider further evaluation with tissue sampling” in that report.

At the end of the day, respecting patient autonomy matters. It sounds like whoever wrote this article would lean towards asking their doctor to collect as much information as possible. Others wouldn’t. In a perfect world, the patient will be well informed by their doctor, be well-counseled on the risks and benefits of a test / intervention, and will be capable of understanding things like statistics well enough to come to an informed decision that works for them. In reality, that often does not happen for a number of reasons.

I can count on two hands the number of nurses at my one hospital who were fired (or forced to resign, or whatever corporate language you’d like to put on it) last year because they refused to get vaccinated and had recently had COVID within the past few months.

I agree. This is kind of bizarre behavior from someone who is such an important contributor to Home Assistant, a large scale open source platform. I can’t imagine most of the leaders in Home Assistant would share this attitude, but maybe I’m wrong.

Imaging in general has an important role in screening for certain diseases, and in some cases is already more important than physical examination. This mainly depends on how "well" physical examinations can detect an illness, the characteristics of a particular imaging study (cost, radiation exposure, etc), and the characteristics of a disease (prevalence in a population, potential benefit of early detection/treatment). So in short, for MRI to replace physical exam and/or lab testing in screening for a particular disease, the cost needs to come down or the benefit should outweigh the cost.

Prostate cancer screening in general is no longer officially recommended by the AAFP as a rule [1], but if a patient decides to opt-in to screening, the "assay" (PSA) is preferred over a digital rectal examination, which has been shown to be increasingly useless in the detection of prostate cancer. MRI doesn't currently have a role in prostate cancer screening, but Prostate MRI has an increasingly critical role in diagnosis.

CT colonography is currently a viable option for colon cancer screening instead of colonoscopy, though colonoscopy is still considered the gold standard.

Chest CT is currently recommended to screen for lung cancer in patient's that meet certain criteria (age, smoking history).

Mammography is obviously the workhorse of screening for breast cancer, rather than physical examination. But MRI is recommended as a screening mechanism for certain patient populations with very high risk of breast cancer (e.g. certain BRCA mutations). The small population, high prevalence, and benefit of early detection combine to make this a viable option.
