How AI Could Change the Future of Medicine
Summary
TLDRThis video discusses how artificial intelligence (AI) is revolutionizing radiology and medical imaging by assisting with early detection and triage of diseases. Rather than replacing humans, AI enhances decision-making by identifying urgent cases, such as pulmonary embolism, more quickly than humans alone. While AI doesn't make definitive diagnoses, it helps prioritize patients who need immediate attention. At institutions like Mass General Brigham, several FDA-approved AI algorithms are being used, particularly in cancer detection, to speed up and improve patient care, but human oversight remains crucial.

Q & A
What is the primary role of AI in radiology and medical imaging?
-AI in radiology and medical imaging primarily helps with triage, detecting early signs of diseases, and analyzing large amounts of data quickly. This allows medical professionals to prioritize patients who need immediate attention.
Why did people initially misunderstand the role of AI in healthcare?
-People initially believed AI would replace humans or function as a General AI capable of making vast decisions autonomously. However, the current role of AI is more supportive, enhancing human capabilities rather than replacing them.
How does AI benefit radiologists in detecting diseases?
-AI benefits radiologists by analyzing data faster and continuously, identifying patterns or anomalies in medical images that could take humans longer to detect, thus improving the efficiency and speed of diagnosis.
How many AI algorithms has the U.S. Food and Drug Administration (FDA) approved for medical imaging?
-The FDA has approved around 420 AI algorithms for medical imaging, most of which are used for detecting various diseases, particularly cancer.
How many AI algorithms are being used by doctors at Mass General Brigham?
-Doctors at Mass General Brigham are using about 50 AI algorithms to assist in patient care, with approximately half of them being FDA-approved and the rest still in the testing phase.
How does AI help in emergency situations like pulmonary embolism?
-AI algorithms can detect pulmonary embolisms in medical images such as CAT scans. While the AI doesn't diagnose the condition, it highlights patients with a higher probability of having the condition, allowing doctors to prioritize care for those patients.
What is the AI’s limitation when detecting conditions such as pulmonary embolism?
-AI does not provide a definitive diagnosis. It simply identifies patients with a higher likelihood of having the condition, which helps doctors prioritize those cases but still requires human intervention for the final diagnosis.
What is the significance of AI's ability to prioritize patient care?
-AI's ability to prioritize care ensures that patients with life-threatening conditions, such as pulmonary embolisms, receive attention sooner, potentially saving lives by reducing the time to diagnosis and treatment.
Do current AI systems in medical imaging work autonomously without human input?
-No, current AI systems still require human intervention. They assist in narrowing down cases and providing suggestions, but the final decision and diagnosis are made by medical professionals.
How does AI improve the workflow of healthcare professionals?
-AI improves workflow by enabling healthcare professionals to focus on high-priority patients more efficiently. It helps by identifying cases that require urgent attention, thus improving the speed of care and reducing the chances of worsening conditions.
Outlines
🤖 The Rise of AI in Radiology and Medical Imaging
This paragraph introduces the expanding role of artificial intelligence (AI) in radiology and medical imaging. Early misconceptions about AI replacing human doctors are addressed, as the current use of AI is primarily for triage—helping to detect and prioritize potential medical conditions in patients more quickly than humans. AI assists by analyzing large amounts of data continuously, offering suggestions where immediate care might be needed. It doesn’t replace human judgment but enhances it.
🧠 AI-Driven Algorithms Approved by the FDA
The U.S. Food and Drug Administration (FDA) has approved around 420 AI-based algorithms, most related to cancer imaging. At Mass General Brigham, doctors are using about 50 of these algorithms, with half already FDA-approved and the others undergoing testing. These algorithms are designed to assist in patient care, particularly in helping detect diseases early or quickly enough to prevent further complications.
💡 AI in Emergency Situations: Pulmonary Embolism Detection
This paragraph highlights a specific application of AI in emergency care: detecting pulmonary embolisms in patients who present with symptoms like shortness of breath. AI algorithms can rapidly identify which patients are more likely to have life-threatening conditions, such as pulmonary embolisms, compared to other conditions like congestive heart failure, which require different treatments. Though AI flags the likelihood of certain conditions, it’s important to note that final diagnoses are still made by human doctors.
🚨 Prioritizing Patients with AI-Enhanced Detection
AI can assist doctors in prioritizing patients based on the likelihood of a serious condition. While AI doesn't give a definitive diagnosis, it increases the chances of identifying patients who need urgent care, allowing doctors to focus on them first. This prioritization improves patient outcomes by ensuring that life-threatening conditions are addressed more swiftly.
👨⚕️ Human Oversight Still Required in AI-Assisted Care
Although AI technology in medical imaging has become more sophisticated, human intervention remains crucial. Doctors review AI-generated suggestions to agree or disagree with the potential diagnoses. AI’s main role is to narrow down the focus for doctors, directing them to the right patients and conditions, which helps in delivering faster and more accurate care.

artificial intelligence is being used to
expand the power of radiology and
medical imaging
the thing that I think confused a lot of
people early on when AI was being
introduced into Healthcare was it was
going to be a Panacea maybe it was going
to replace humans in this process or
that General AI was going to be able to
look at massive records and make massive
decisions I'm not saying that that isn't
going to happen someday but the product
is products are really around that
triage finding things early finding
things in large quantity so where it
might take a human days to be able to
find a diagnosis whereas computers can
run without sleep continuously and find
those those patients that need triage
care right away the U.S Food and Drug
Administration has approved around 420
algorithms involving Ai and imaging for
various diseases most of them in cancer
at Mass General Brigham doctors have
about 50 such algorithms to help them
with patient care about half have been
approved by the FDA and the remaining
ones are still being tested there are
certain conditions that if you don't
treat quickly the patient worsens or
could actually pass away and so examples
of that would be like pulmonary embolism
in the ER setting a patient comes in
with shortness of breath that could be
one of the things they have but it might
not be the thing that they have could
have congestive heart failure which gets
treated differently so now there are
algorithms that can detect pulmonary
embolisms not a CAT scan of the chest
and so when that gets detected it
doesn't make the diagnosis it's
important to note that it's not saying
this is definitely what it is it's
saying that the probability of this
patient having it is much higher than
this patient and so you should look at
this patient first when you have a
series of patients that you need to care
for it does help to get that bump up in
the list to be able to say I should look
here first because there's a higher
likelihood that this patient has that
and needs the treatment
but all of these uh
um different levels of AI all today
require a human intervention to come in
and say I agree or disagree so depending
upon today the sophistication of AI it
just makes it easier for that human to
focus on the one area and to focus on
the right patient to say how do we get
care faster
