DALL-E, Draw an AI Doctor
BY KIM BELLARD
I can’t believe I somehow missed when OpenAI introduced DALL-E in January 2021 – a neural network that could “generate images from text descriptions” — so I’m sure not going to miss now that OpenAI has unveiled DALL-E 2. As they describe it, “DALL-E 2 is a new AI system that can create realistic images and art from a description in natural language.” The name, by the way, is a playful combination of the animated robot WALL-E and the idiosyncratic artist Salvator Dali.
This is not your father’s AI. If you think it’s just about art, think again. I...

A woman in her 30s with sudden chest pain, nausea, and diaphoresis. Was her cardiology management appropriate?
Case written and submitted by Brandon Fetterolf MD, edits by MeyersA woman in her early 30s with multiple autoimmune disorders including vasculitis presented with 2-3 hours of mid-left side chest discomfort with radiation to neck and left arm and associated with nausea, diaphoresis and dizziness. Initial ECG on presentation at 1554 (no prior for comparison):What do you think is happening to his 30s woman? The ECG shows NSR with a normal QRS except for poor R wave progression and pathologic QS-waves in V2-3. There is STE and hyperacute T waves in V2, I, and aVL with reciprocal STD in II, III, and aVF. This is...

vMap Mapping Technology for Cardiac Arrhythmias: Interview with Mike Monko, CEO of Vektor Medical
Vektor Medical, a medtech company based in San Diego, created the vMap system, a mapping solution for cardiac arrhythmias. The system is the first to identify arrhythmia sources anywhere in the heart, including the septal wall, outflow tracts, and all four chambers. The company reports that the technology takes less than three minutes to provide a result.
The system uses 12-lead electrocardiogram (ECG) data to pin-point the location of an arrythmia, and so is non-invasive. Accurate mapping of arrythmia sources is important in ensuring that subsequent treatment is successful. In the case of ablation for atrial fibrillati...

Device Makes Diffuse Ultrasound Waves for Intracranial Applications
Researchers at the University of California San Diego created an ultrasound transducer that is intended to provide safer ultrasound treatment when working inside the brain. Ultrasound has significant therapeutic potential for various ailments that originate in the brain, including epilepsy, and next-level sonogenetics involves targeting various cell types in the brain to make them responsive to ultrasound. However, current ultrasound devices use focused waves that can bounce around inside the skull, potentially causing injury. This latest technology uses the same mathematics that ensure sound diffusion in concert halls to ...

Magnetic Tentacle Robot Travels Deep into Lungs
Researchers at the University of Leeds in the UK have created a magnetic “tentacle robot” that is just 2 mm in diameter, which they hope will be able to navigate through some of the smallest airways in our lungs. At present, a bronchoscope is used to investigate the lungs, but this cannot pass into very narrow airways without an additional catheter attachment. This arrangement is cumbersome and difficult to navigate. This new technology is controlled autonomously using external magnets mounted on robotic arms and does not require X-ray imaging during the procedure. The researchers hope that the device will aid clinicia...

Decisions made by human experts can be as inscrutable as those made by algorithms — but we don’t realise it
By Emma Young
Let’s say you’ve been found guilty of stealing a car. Would you prefer that a judge decided your punishment — or an algorithm?
Algorithms are increasingly taking over from people in making decisions in everything from the hiring of new employees to healthcare, as well as criminal punishment. But, as the authors of a new paper in the Journal of Experimental Psychology: General note, there is mounting public concern about just how algorithms reach their decisions. In some US states, for example, companies that use algorithms in hiring are now obliged to explain the steps of the process.
However,...

How to approach 1st year in Radiology Residency- Dr Sumer Sethi
Radiology is a discipline which provides multi-faceted exposure to its pupils. Several post graduates all around the world opt for radiology for this. But it is often confusing for freshers in their initial stage of radiology residency. Students do not have a properly caved path to follow in order to excel in this field. And that is simply because there is not much preparation required to prepare for learning radiology. You must let this specialization take over you rather than trying to get ahead of it. For a 1styear residency student the primary thing one must grasp is the actual concept and function of radiology. M...

New Vascular Contrast for Clearer Blood Vessel Imaging
Researchers at Johns Hopkins developed a new imaging technique that allows them to view the vasculature of experimental animals in great detail. Research into a variety of conditions, from vascular disease to cancer, relies on acquiring images of the vasculature in animals, with a variety of imaging techniques available. These researchers have created a unique blend of polymer contrast agents which can be perfused into the vasculature, permitting imaging using optical microscopy, MRI, and computed tomography (CT). The combined imaging creates highly detailed tissue maps of the vasculature at different spatial scales, revea...

What Has A.I. In Medicine Ever Done For Us? At Least 50 Things!
Remember Monty Python’s brilliant Life of Brian movie scene where the Judean Jewish insurgent commando, planning the abduction of Pilate’s wife in return for all the horrors they had to endure from the Roman Empire, asks the rhetorical question: what have the Romans ever done for us? With the hype and overmarketing, not to speak about the fears around A.I, we asked the same question. What has A.I. in medicine ever done for us? Well, we found at least 50 things.
I have 50 responses to the pressing question on everyone’s mind who is interested in healthcare but tired of the hype or the doomsday scenarios around A.I....

The Art and Science of solving MCQ ’s like a topper
MCQFascinating, isn ’t it? The way three simple letters resonate in your nightmares, overload your cognitive senses in moments of truth and make you curl up in your blanket and pray to almighty. And all of this is done by actually displaying the answer to a posed question right in front of your eyes, hidden within ot her choices. But students would rather have no choice to begin with rather than being tricked by the illusion of choice.I am here to tell you there are ways to break this illusion and attain clarity. Being an average student, from an average school, with above average ambitions I was told that I might excel ...

Funky Helmet Enhances MRI Brain Scans
A team of engineers and radiologists at Boston University created a helmet that can dramatically improve MRI scans of the brain. The device consists of a series of magnetic metamaterial resonators that significantly boost MRI performance. This results in crisper images that can be obtained at twice the speed of a normal scan. The breakthrough may allow clinicians to obtain useful images from low-field MRI scanners, potentially expanding the accessibility of brain scans to people in low-resource regions of the world.
MRI is an incredibly useful imaging technique, but it can often be difficult to achieve the image resolut...
