The positively-charged anode, a flat disc made of tungsten, draws the electrons across the tube. X-ray machines seem to do the impossible: They see straight through clothing, flesh and even metal thanks to some very cool scientific principles at work. Find out how X-ray machines see ...
After carpal tunnel surgery, I later learned that my hand numbness was caused by herniated discs in my neck. Over 70% of patients receive an incorrect diagnosis for similar symptoms. Learn how to avoid the same mistake.
Here, the important question is: how will the cell respond and adapt itself to a high magnetic field gradient? From point of view of physics, the answer is the following. Considering the cell as a droplet of diamagnetic liquid placed in a non-uniform magnetic field, one can conclude that ...
Model Development To tackle the problem of bubble formation at porous electrodes, in this section we start by considering a single bubble that is placed into an electrolyte. Based on simple energy considerations, we develop the bubble growth law that is central to this work. Thereafter, we ...
source: Dr. GrumpyBut do not fear disc herniations! No matter how bad it looks on a CT scan or MRI, it is not necessarily the cause of the problem. Herniations correlate rather loosely with actual pain. They may be a distracting sideshow that unnecessarily worries people.As...

Need I go on? With these and many other radical changes and innovations in technology almost too numerous to mention (add the pocket calculator, the Atari, the Apple II, the VCR, the Handicam®, the compact disc and Diskman®, the wireless telephone, the Internet, the MP3 player, etc...
The entire mechanism is surrounded by a thick lead shield. This keeps the X-rays from escaping in all directions. A small window in the shield lets some of the X-ray photons escape in a narrow beam. The beam passes through a series of filters on its way to the patient. ...
All patients referred to the spine centre received conventional radiographic imaging (X-ray) of the spinal region for which they were referred. Of the 1008 patient subgroup, 682 (67.7%) received additional imaging diagnostics. Of these patients, 638 (93.5%) received an MRI scan, and 113 (16.6...
on single-level nerve root compression (caused by a herniated disc, stenosis of the lateral recess, or neuroforamen) confirmed by morphological imaging (MRI or CT). The definition for predominant pain resulted from the highest NRS value (back vs. leg). All patients were mentally and physically...
