A.I. In Healthcare: 8 Exciting Insights From A New E-Book
Far from being the futuristic promise it once was, artificial intelligence (A.I.) is an unavoidable eventuality in virtually all sectors. Heeding to its potential, governments around the world are collaborating and taking steps to ensure the responsible development and use of A.I. One such recent example is the Global Partnership on Artificial Intelligence (GPAI) jointly created by 14 governments and the European Union in 2020.
Healthcare will also need to brace itself for this disruptive force. Already, the number of life science studies published around A.I. rose from 1,600 in 2010 to 7,300 in 2020. The technology is ...

Listen Better, See Deeper
Combining Medical Attentiveness with Artificial IntelligenceJohn Halamka, M.D., president, Mayo Clinic Platform, and Paul Cerrato, senior research analyst and communications specialist, Mayo Clinic Platform, wrote this article.Embracing an “ecology of attention” will significantly improve patient care, according to Mark Kissler, MD, at the University of Colorado.1Kissler and his colleagues point out that clinicians spend much of their time multi-tasking and navigating around interruptions. While such juggling acts are often unavailable, it ’s important to occasionally step back and ask: Is this the best use of my tim...

How residents can create a positive clinical learning environment [PODCAST]
“For me, the team room became a safe space filled with light, stories, laughter, and food. There, my residents helped me read CT scans, interpret CBCs, come up with the differential for bradycardia, and organize my oral presentations. My residents gifted me confidence, advice on the third year and specialty selection, and Dr. Pestana ’s Surgery […]Find jobs at Careers by KevinMD.com.

The Paradigm Shift That Wasn ’ t: The ISCHEMIA Trial
By ANISH KOKA
A recent email that arrived in my in-box a few weeks ago from an academic hailed the latest “paradigm shift” in cardiology as it relates to the management of stable angina. (Stable angina refers to chronic,non-accelerating chest pain with a moderate level of exertion). The points made in the email were as follows (the order of the points made are preserved):
The financial burden of stress testing was significant ( 11 billion dollars per annum in the USA!)For stable CAD, medical treatment is critical. We now have better medical treatments than all prior trials including ischemia. th...

Discordant grading of severity of aortic stenosis
Discordance between various measures of severity of aortic stenosis (AS) is considered as discordant grading of severity of aortic stenosis or simply discordant AS. Severe aortic stenosis has aortic Vmax ≥4.0 m/s, mean gradient ≥40 mm Hg and effective orifice area (EOA) ≤1.0 sq. cm. Peak aortic velocity and mean gradient are flow dependent measurements, while effective orifice area and Doppler velocity index are relatively flow independent.
About 20-30% of patients may have discordant measures of severity of aortic stenosis on echocardiography [1]. Discordance is mostly between effective orifice area and Vmax/Doppl...

Clear Cranial Implant Allows Ultrasound Imaging of Brain: Interview with CEO of Longeviti Neuro Solutions
Longeviti Neuro Solutions, a medtech company based in Maryland, has announced that its ClearFit cranial implant has been cleared by the FDA for post-surgery ultrasound imaging. The clear implants are used for cranial reconstruction after brain surgery, and are custom-made for each patient. The company uses patient CT scans and 3D printing to produce the custom implants, and then sends the sterile constructs directly to surgeons.
Typically, ultrasound imaging of the brain is not possible in adults because of the properties of the skull. The implants allow clinicians to perform this task by being nearly transparent to ult...

Changes to radiation oncology offer hope when there was none
Radiation oncology has been around for a century, and, at first, advancements in the field came rapidly. The evolution of X-rays and CT scans to inform treatment. Intraoperative radiation therapy. Technology that allows for tailored dose distribution. But for the past 20 years, the pace of innovations seemed to slow. We remained stymied, for instance, […]Find jobs at Careers by KevinMD.com.

Improving PET scans are good news for doctors and patients alike
A recent blog post discussed a newly approved imaging agent with an unwieldy name: gallium-68 PMA-11. Delivered in small amounts by injection, this minimally radioactive tracer sticks to prostate cancer cells, which subsequently glow and reveal themselves on a positron emission tomography (PET) scan. Offered to men with rising PSA levels after initial prostate cancer treatment (a condition called biochemical recurrence), this sort of imaging can allow doctors to find and treat new tumors that they might otherwise miss. With currently available imaging technology, such tumors could potentially escape detection until they we...

Septal bounce and septal shudder in constrictive pericarditis
Septal bounce
Septal bounce is also called respirophasic ventricular septal shift [1, 2]. It is an early diastolic posterior motion of the interventricular septum. Septal bounce is a sign of ventricular interdependence noted in constrictive pericarditis. The sign may be seen on echocardiography, cardiac magnetic resonance imaging and cardiac computed tomography. Mechanism has been studied by simultaneous cardiac catheterization and echocardiography [2]. Septal bounce was the most consistent sign among 39 cases of constrictive pericarditis evaluated by two independent observers in a study [3]. Septal ‘bounce’...

ST Depression Maximal in V1-V4 and Angio shows 3 Vessel Disease. Is it posterior? Which is the culprit?
A 70-something woman had acute chest pain.The ECG was texted to me with the words: " Acute chest pain. Could this be posterior MI? What do you make of the ST depression in V4-V6? "What do you think?My response: " The ST depression is maximal in V1-V4. This is most consistent with a posterior MI. If it sounds clinically like acute MI then this is good for activating the cath lab. "Her response: " Yeah, I did activate. But the cardiology fellow told me he was sure it would not be a posterior MI because of diffuse ST depression. He suggested that we should have consulted cardiology rather than activati...

FFR with CT angiography
Fractional flow reserve (FFR) is usually estimated invasively using a Doppler flow wire introduced into the coronary artery and measuring the pressure drop across the coronary stenosis during maximal hyperemia induced by adenosine. FFR has been shown to be of great significance while assessing the severity of borderline coronary stenosis in deciding the need for coronary angioplasty. Fractional flow reserve estimated by computed tomographic angiography (FFRCT) is a novel technique of getting similar information non invasively. FFR with CT angiography has been shown to be superior to conventional CT coronary angiography a...

Docs are ROCs: a simple fix for a “methodologically indefensible” practice in medical AI studies
By LUKE OAKDEN-RAYNER
Anyone who has read my blog or tweets before has probably seen that I have issues with some of the common methods used to analyse the performance of medical machine learning models. In particular, the most commonly reported metrics we use (sensitivity, specificity, F1, accuracy and so on) all systematically underestimate human performance in head to head comparisons against AI models.
This makes AI look better than it is, and may be partially responsible for the “implementation gap” that everyone is so concerned about.
I’ve just posted a preprint on arxiv titled “Docs ar...

Don't Just Rely on X-Rays
A woman in her 50s reported
four days of left-sided pleuritic chest pain in her lower ribs. No other symptoms:
no fever, trauma, shortness of breath, cough, or wheezing. It's COVID times, so
who knows? A chest x-ray and labs were ordered. The x-ray appeared clear.
Perhaps it was pleurisy. The white blood count was more than 17 mL! Still no fever:
99.2°F.Then the D-dimer came back
elevated. A chest CT angiogram was obviously the next step. Maybe it was a pulmonary
embolism.Surprise! It was pneumonia,
and it wasn't a little one!Chest x-rays are used as a
screening tool for pneumonia. They require le...

RWMA – Echo
RWMA – Echo
The term regional wall motion abnormality or RWMA can be used in any imaging which shows movements of the myocardial segments like echocardiography, cine cardiac magnetic resonance imaging, cine computed tomography and nuclear cardiology imaging. The left ventricular myocardium has been divided into 17 segments by the American Society of Echocardiography [1]. The true apex is a separate segment in this 17-segment nomenclature. In the previous 16 segment nomenclature, there is no separate true apical segment. True apical segment is beyond the left ventricular cavity towards the apex.
