Here to say sometimes the highest MCAT/USMLE scorers aren't always the best physicians.
You can ace a test, but if you don't know how to communicate with others and be considerate, you won't go to many places
Plus there's evidence showing MCAT scores is associated with SES

@drterrysimpson For limited resources like slots at a top medical school, objective measures of competence like the high MCAT range should be the major factor in sorting applicants.

@thewcd4 @dr_huffer You’re not thinking that when interviewing candidates. You’re looking at their appearance, their grooming, their body language when answering different and potentially difficult questions, etc. These type of things matter when evaluating applicants. We aren’t robots.

@gasmantx @dr_huffer But when your premise is “we dont have enough of x” or “we have too much of y”, how do you stay objective?

@dr_huffer I would definitely object. You learn a lot about people meeting them face to face. In medicine part of our job is communication and professionalism. I’ve seen some interesting things meeting with candidates for admission for both med school and residency.

@thewcd4 Telling a 36 year old mother of three that the lesion we biopsied was a melanoma met and she is now stage IV. A leukemia cutis diagnosis in an 27 year old with no medical history. Telling a parent their infant has Langerhans cell histiocytosis.

I was in the middle of a LONG breast reconstruction surgery.
I was retracting for a very long time and couldn’t see anything.
The surgeon was peppering me with anatomical questions as I was retracting, and I was struggling..
So after a while he says, “Williams. You’re a rock. What I mean is - you’re as dumb as one.”

🫀⚠️ We used to say: “It’s non-obstructive, don’t worry.”
This paper suggests we may have been… very wrong. Photon Counting CT answers NEW questions.
A simple but powerful case:
👉 74-year-old patient
👉 unstable angina
👉 non-obstructive disease on CT
And yet:
👉 Photon Counting CT detected plaque ulceration.
Confirmed by OCT.
Let that sink in.
This was NOT a tight stenosis.
This was:
👉 biologically dangerous plaque
👉 invisible to conventional paradigms
👉 clinically relevant
The key finding
Ultra-high-resolution PCCT showed:
👉 non-calcified plaque
👉 spotty calcification
👉 positive remodeling
👉 sharp angular protrusion (ulceration)
—all non-invasively.
Translation
We are starting to see:
👉 plaque rupture biology without a catheter.
And this matters.
Because plaque ulceration (cap disruption + cavity formation) is:
👉 one of the main substrates of ACS
Traditionally detected only with:
❌ invasive angiography
❌ OCT
This is the real shift
From: ❌ “Is there a stenosis?”
To: 👉 “Is this plaque dangerous?”
The uncomfortable implication
A patient can have:
👉 “non-obstructive CAD”
and still carry:
👉 rupture-prone disease.
My take
Photon Counting CT is not just improving image quality.
It is:
👉 exposing the blind spots of lumen-based cardiology.
Bottom line
If you only look for stenosis:
👉 you will miss biology
👉 you will miss risk
👉 you will miss patients
⚡ The future is not:
“better detection of narrowing”
It is:
👉 detection of instability

As I go through the variety of clinical cardiac comments on this platform I continue to learn from facts and challenges to my understanding and am convinced that scientists use a different numbering system than the deniers , the grifters, the braggarts, and the truly confused use. I am brought back to the old medical jokes such as do one then teach one then publish one. But my favorite is the first time you see or hear of a case it in your experience; the second time is in your series; and the third time is case after case after case.

You are quite right that we visually call a stenosis higher than visually seen on cath because we see the whole vessel and not just a shadow of the vessel inside. That is why CCTA FFR eliminates the over all and now with AI and plaque WALL imaging with CCTA we see the whole inside and outside of the vessels. Also BTW a 25% stenosis is not normal and increases risk significantly

@DrRumberger Everything called 50-70% by ct is typically <25
