Tablet PCs, smart phones in healthcare? Detecting airborn toxins with your cell phones? Mobile reference guides for doctors and medical students? Is this just the future or is it happening now? NursingSchools.net has posted an article about trends in mobile medical technology that I found worth sharing with you.

From shrinking computers to powerful smartphones, mobile technology has also had an amazing impact on the medical field, and it’s revolutionized the way medical professionals work, from world-class hospitals down to nursing schools. Here are 10 trends in mobile medical technology that are rewriting the rulebooks.

No doubt mobile technology is not only changing the way we live our lives, but it also changes our perspective on medical information. I, as a resident doctor, on many occasions find myself browsing for medical information such as medicine side effects between seeing two patients at the Internal Medicine Department of the hospital I am in.

ThermoDox October 17, 2008

I am certain that one day there will be a cure for cancer, that is why I try to keep up to date with whatever advances there are in cancer treatment. I stumbled upon ThermoDox, an interesting technology that utilizes heat-activated liposomes to kill cancerous cells.

Liposomes are made of that same materials as cells, phospholipids, thus they form a hollow structure that is soluble in water but may fuse with cell membranes. Since they are hollow, they may be filled with anti-cancer drugs.

ThermoDox liposomes are filled with Doxorubicin, a popular anti-cancer agent. They circulate within the bloodstream, so they reach all parts of the body, but only when focused heat is applied do they release their deadly load onto cancerous cells. Thus side-effects are reduced, and more efficient cancer treatment is achieved.

ThermoDox is now in phase III, and you may read more on this technology here.

Magnetic Resonance Imaging or MRI for short is a popular noninvasive diagnostic imaging modality. MRI provides much greater contrast between the different soft tissues of the body than computed tomography (CT) and it does not utilize ionizing radiation making, thus it has become popular in Oncology, Neuroradiology, and othe fields of medicine.

In cancer treatment early detection is everything. If one catches a tumor at an early stage, chances of long-term survival are favorable. MRI, amongst other imaging modalities, is used to detect and stage various cancer types. Contrast agents such as Gadolinium may be used to further increase the contrast between normal and abnormal tissues in the human body.

Recently, Michael J. Sailor of the University of California at San Diego have developed an agent called “nanoworm” basically strings of iron-oxide particles, that will attach themselves to cancerous cells and show up more vividly on MRI scan making it easier for doctors to catch tumors at earlier stages before they become incurable. These worms will attach to cancerous cells via cancer-specific antibodies.

eXplore CT 120

There has been some words on fast spinning CT scanners on this blog recently, so if you saw those videos and image that GE’s latest pre-clinical CT scanner is able to capture images of the hearth beating as high as 600 bpm, you probably have a hard time imaging what is going on inside this beast! Pre-clinical diagnostic imaging machines are for testing new molecules, drugs and procedures on animals before they are tested on humans. GE has just come out with its latest installment: the eXplore CT 120. It features ECG and respiratory gated cardiac imaging, improved soft-tissue contrast and overall image quality, and “compatibility throughout the eXplore series of imaging systems for seamless PET and SPECT co-registration.” For breathtaking images, visit the official GE website.

PET/CT Reader On Your iPhone June 28, 2008

When the iPhone came out I said: “I gotta have one of this!” As I am entering the last year of medical school and edging more towards real clinical imaging work in the field of nuclear medicine I say : “I need one of these as soon as possible!”

MIM for iPhone

I wrote about how iPhones could be used in diagnostic imaging and why all radiologist should carry one in their pockets wherever they go, but now PET/CT readers have a reason to do so as well. MimVista has just recently come out with a multi-modality imaging software for the iPhone that is absolutely mind blowing.

You may not only view PET/CT combined data on your phone, but you may use all those tools that you are used to on a workstation. For example:

  • find the contour of the lesion in 3D
  • calculate min. and max. SUV values
  • calculate the volume of the lesion.

And that is just of the many uses of this software that soon may change the way we learn and work!

Take a look at this video to find out more about this emerging technology:

Meet Toshiba’s new scanner: Aquilion One June 21, 2008

Posted by tomography in CT, development, Innovation, Radiology.

It is official! Toshiba’s new Aquilion One scanner is out! After 10 years and 500 millions dollars of development, new 320-slice scanners are going online in select hospitals in three major U.S. cities: Baltimore, Boston and Las Vegas. Toshiba gets the last laugh having been previously outpaced by one of its major competitors, Philips Medical Systems. The technological details are impressive:

  • It uses 320 ultra-high-resolution x-ray detectors, each half a millimeter wide
  • The detector rotates every 350 msec
  • Single pass of the brain provides the volumetric data to produce CT angiogram, venogram, digital subtraction angiogram, and whole-brain perfusion images
  • A whole heart can be captured in a single rotation
  • All this with even less radiation burden on the patient

According to the official website your hospital may save considerable amounts of money, if this machine is used in events such as acute chest pain and stroke. For example, in practice this is how it would work out. Let’s suppose a patient comes in with acute chest pain. You examine him, take an ECG reading, order a CT scan, or a nuclear stress scan, and then finally send him to intervention cardiology, where he receives his proper treatment (a stent for example). It is estimated that all this would cost around twice as much (and much more time) as having him lay down in an Aquilion One, and then send him to intervention. I see their point, but I think that this does not hold for all cases as implied by the company website. The emphasis should be on proper events!

By the end of the day it is about people’s lives and correct diagnosis, so I am happy that new advances in technology are helping us achieve those goals easier. If anybody has any images taken with such a high resolution scanner (does not necessarily have to be with this particular type), please email it to us!

Diagnostic Imaging Professional’s Dream # 2 June 19, 2008

– In the first edition of this series I covered Optimus Maximus, Optimus Mini and Optimus Tactus. Since then a couple other companies came out with novel, and sometimes shocking ideas, so I gathered you another list. I hope you will find yourself the one that will make your heart skip a beat.

1. First of all here is the flattest full size no-key keyboard of all time by designer Kong Fanwen. It looks great, and it would make any of your co-workers drool, but it has no tactile feedback, and I wonder how much pressure it may stand. Don’t drop this one, though, cause it would not do you much good trying to glue the broken pieces of glass back together. It truly is beautiful; no question about that!

2. This one if for those who get green with envy looking at most Macs that have an illuminated keyboard. Now you can have it on a PC! So if you hate turning the lights off while looking at x-rays and typing at the same time, this one is for you.

3. Art is at the heart of a great concept and Japanese artist, Kazuharu Sakura knows that too well. He creates astonishing pieces of art, and here is the latest of his work: a leather keyboard. Image touching nothing but soft leather while working on your computer! That is a bit too luxurious, so if you get one of these do not leave it at the office. Rest assured, take it with you if you go out to the lavatory!

4. Maximus was so popular in our first edition, I had to take a look around their headquarters as well. Here is what I found: Optimus Upravlator. There is word on the street that it is more like a grown up version of the Optimus Mini we discussed previously. It is an input device, but after all, most of Artlebedev‘s products should be called input devices rather than keyboards. “It features a 10.8 inch color LCD (800 ×600 pixels resolution) with 12 see-through buttons occupying its surface. Each of them has five contact points—center, top, bottom, left and right—freely assignable to user interface elements in the software of your choice.”

Happy shopping everyone!
