When IBM Watson Looks – Does It See Pictures or Patients?

This TV commercial caught my attention a few days ago.

In the TV spot, the narrator outlines the number of images a radiologist must parse through to find an abnormality. To help, IBM will teach its Watson “to see.”

Therein lies the problem: Seeing is not enough. Continue reading

The 5 Myths of Open Source – A Guide for The Non-Programmer

This is the second of a series of three discussing open source software for non-programmers interested in informatics.

A previous post discusses what you can expect from a software project when it is “open source.” However, the concept of OS is not so clear cut.

This post aims to clarify five commonly held beliefs about open source.

What Is Open-Source? A Guide for The Non-Programmer

This is the first of a series of three discussing open source software for non-programmers interested in informatics. I try to stay as accurate as possible while avoiding jargon.

Open source (OS) has been a popular phrase not only in software engineering but also in radiology. Open source is closely tied to DICOM, the most popular format in medical imaging, in part because many frameworks available to manipulate DICOM files are open source.

A thorough discussion on OS is available here.  If you are more into an abbreviated 3-minute introduction, stick around.

7 Things Worth Checking out at SIIM 2015

Society of Imaging Informatics in Medicine (SIIM) is having its 2015 meeting in Washington DC from 5/28-5/30. SIIM is a wonderful event with something to offer to engineers, clinicians, and radiology trainees alike. For a resident it is also an opportunity to learn something new.

Aside from all the cool sessions during conference, also do remember to touchbase with old friends and meet new people. The point of a great conference is the great people.

During the day, though, it can be daunting to keep abreast all the things that are going on.

Here are 7 events that compelled me as can’t-miss sessions – to be used as a roadmap for myself at the conference, and shared with you now:

A World Without PACS

Woodrow Wilson A
Thursday, 8:00 am – 9:30 am

Traditional PACS – solutions with vendors, hardware, and software all integrated as a single offering, is a decades-old technology – Slowly, imaging in America is moving towards vendor neutral archives (VNA).

Is Radiology Ready for The Cloud?

Taking radiology to the cloud is not a new concept. It has already been discussed here and here, with lowest hanging fruit use-case being cross-institutional image sharing.

The excitement for cloud is certainly abuzz in the non-healthcare market. Several days ago, @TheEconomist tweeted a message ending with “the whole IT business will change.” They were referring to the maturing migration of technology into the cloud.

What caught my eye was not the tweet itself, but the accompanying graphic, illustrated by Satoshi Kambayashi.

A winged piggy bank with the General Electric logo receives a boot in the loin, eyes wide open with surprise as if he didn’t see it coming at all. General Electric, of course, is one of the biggest vendors in radiology hardware.

So are radiology practices ready to kick GE, too?

Robots and Radiologists

In an article titled “The Robot as Radiologist,” Dr. Douglas Green from Univ. of Washington acknowledges the rapid advances in computational image recognition and advent of IBM’s Watson.  He concludes the commentary by taking solace in the fact that, at least for the time being, artificial intelligence is complementary rather than substitutional to human radiologists.  I wholeheartedly agree.  However, Harvard Business Schools gurus do not.

5 Tech Tips Before Starting Radiology Residency

After a well-deserved celebration, the medical students who matched into radiology this year will realize what they’ve known all along – it will be a little more than a full year before they would start the actual residency they signed up for.

In many training programs, this post-match, pre-July-1 time is when the attention starts to focus on the folks who matched last year, those who will be starting in three months. Personally, April was when I also began to both getting psyched about starting a new residency program and getting nervous about preparing.

This post is about buying technology for those who are fixing to start radiology residency this year.

1. Find out If Your Program Has a Computer Fund

Any form of technology is a serious investment for a resident, as a computer can easily cost you a 2-week paycheck.

Before you buy anything, find out if your residency program provides funding for new computer and/or textbooks.

If it does, then great! It is then worth finding out when you can start using it. For instance, my residency program requires that you be officially working – i.e. July 1 – before you are eligible for the professional funding.

2. Get at Least One Portable Computer/Device

A paper in Academic Radiology states that having ready access to technology will become increasingly important in education.

The PACS stations at some hospitals provide unlimited access to the web and are outfitted with modern web browsers and office tools, but others may provide heavily filtered web access with minimal applications. Unless you are certain that your situation is the former, it would be worth having some form of portable computer/device.

Which form factor you decide to go with – tablet, ultrabook, regular notebook, or phablet – is a personal choice. Just keep in mind that the things you might end up using them for:

  1. Take notes during conference
  2. Look up a diagnosis or finding on Radiopaedia.org or one of its commercial competitors
  3. Integrate with electronic medical records – some institution’s EMR would ask that your device meet some security feature requirements
  4. Access the digital edition of a textbook
  5. Touch up a slides presentation for journal club or case conference

3. Get a Twitter Account

Social media is becoming increasingly important in radiology. Any national radiology conference you attend will have a strong Twitter presence, and many people are also on LinkedIn.

Since one of your tasks during the residency is to learn about the most pressing issues in the radiology community at large, becoming familiar with tools like Twitter can be tremendously helpful.

Also, if you start now, you can grab all the cool names before someone else gets them.

4. Avoid EInk Readers for Radiology Books

Radiology textbooks are expensive. It is made worse by the fact that there are so many of them! You will need a book for each subspecialty to really learn the nuances of each rotation.

Unfortunately, eInk readers are just not good enough for images on radiology. Kindle Paperwhite, for example, sports only 16 shades of grey. Reading the same books on a tablet like the iPad, Nexus 9, or Kindle Fire is a different experience, owing to the markedly improved contrast resolution over eInk.

However, be careful that sometimes Kindle or EPUB format books compress images so much that the quality is visibly degraded.

This is not to say electronic books are bad. Buying electronic books can be a good way both to save Benjamins and to reduce the weight of your bag if you load them on a tablet instead of carrying the hardcover incarnations.

EInk readers are great, and I love my Kindle Paperwhite. They are just not for radiology images.

5. Decide If You Want to Pay for an Anatomy Resource

If you are anything like me, you would find memorizing anatomy in a vacuum nearly impossible. Incidentally, it is also one of the most important funds of knowledge to acquire as a first year resident.

Therefore, it is sometimes worthwhile to have access to a good anatomy resource for use on-service. There are free resources like HeadNeckBrainSpine neuroradiology and XRayHead for MSK MRI. e-Anatomy by IMAIOS is an atlas that has some free content but is mostly a paid resource.

At some point you will have to decide whether free resources are sufficient for your needs. Your institution may provide access to a paid resource already, or your professional funding may cover it. If you have to pay out-of-pocket, consider the possibility of sharing an account with a co-resident (make sure you are not violating the user agreement, though).

Conclusion

Radiology residents use more technology than possibly more than other specialty residents from devices, educational resources, to social media. Ultimately how much technology plays a part in your training is a personal preference. However, keeping some of the above points in mind may help you avoid making bad purchase mistakes and be more prepared for July 1.

When We Care, We Share – But Where?

As radiologists, why keep a blog yourself when academic journals, professional blogs, or even newspapers offer a wealth of outlets to share your thoughts?

In a blog post, Arjun Sharma observes that the multitude of places to express his opinions a confounding option. Then, he and I exchanged a few emails seeking an answer.

SPIE 2015 Talks Big [data]

This past weekend, I had the opportunity to attend the SPIE Medical Imaging conference held in Orlando, FL. My visit was cut short to a single full day, but it was enough to learn a great deal.

The meeting is divided into different tracks, each a themed conference with a keynote speaker, paper presentations, and a workshop. Attendees are free to switch from room to room to attend different topics. These are generally engineers, physicists, computer scientists, as well as industry leaders in imaging technology like IBM and Siemens. I spent most of my day in the PACS and Medical Informatics (9418) conference.

Stop Using Tablets/Phones/Computers before You Go to Bed!

According to some smart Harvard people, anyway.

Because evolution never expected humans to develop ways to produce light, our bodies are wired to assume that nightfall is all dark.  A December 2014 study from PNAS states that the light from a back-lit computer screen degrades sleep hygiene from a hormonal level.
