You're making some very interesting and valid points. You've correctly identified that when receiving bundled services you lose the ability to negotiate or comparison shop on the basis of price. This is unfairly combined with a le

There's a lot to unpack here! In the USA, the ABR regulates human radiologists via board certification. Medical technology is traditionally regulated by the 510K, PMA, and de novo pathways at the FDA. Of course, these products still ha

Interesting, can you give an example of a radiologist hindering progress? You make an interesting point about radiologists setting practice standards - what alternative do you propose? You may also want to consider that radiologists don&#x2

For those interested, here's a nice Tweet and video from a neurosurgeon at the Mayo clinic in Arizona demonstrating the use of both fMRI and intraoperative motor mapping: "Preoperative and Intraoperative mapping help with selectio

I respect your experience, and I'll concede that fMRI for pre-surgical planning in neurooncology is used at only some centers. If you worked mainly in neurooncology you may have missed some of the uses of fMRI for epilepsy surgery. Tha

I'm not on the outside of medicine. Significant practice variation exists, but complex neurosurgical conditions are usually managed at academic centers and fMRI is used for planning in neurooncology [1] and epilepsy surgery [2]. [1] h

Awake cortical mapping has much better resolution than fMRI, and it avoids image registration issues, but it requires a great deal of planning and patient motivation. If it turns out that the language center is on the opposite side from the

Thank you for sharing your story. Although fMRI has low resolution, it can be very useful for surgical planning in certain clinical scenarios. For example, to determine hemispheric dominance: "Although the estimated percentages are of

fMRI is used to plan procedures that put eloquent cortex at risk. For example, tumor resections. Typically, fMRI is used for initial planning (whether the tumor is in the dominant hemisphere, how to approach the tumor). Then, in the actual

In addition to what other commenters have said, I'd guess that some purpleair sensors are placed in garages or other places with a local concern for air quality. That may explain some of the local variation you see on purpleair.

Kapton is an outstanding substrate material for flexible printed circuits. It has one of the lower dielectric loss tangents available, and this becomes important in RF and microwave applications. However, PTFE is better.
