Basic research often takes time to show up in practical uses. The transistor was invented in 1947 by scientists studying solid-state circuits but was only put into radios in the 1960s. Now, life without the transistor is unimaginable. Nuclear magnetic resonance (NMR) was discovered in the 1940s but was...
--Talk about a headache. Using PET-scan imaging, researchers find that a CONCUSSION can cause cell damage that persists for several months in an area of the brain related to cognitive functioning. Patients, while not usually severely disabled, are often left with problems in performing difficult tasks.
For better or worse, the driving force behind that revolution is pure economics. Gamma-radiation knives, wondrous devices that focus tiny cobalt beams precisely on microscopic brain malignancies and malformations, cost $3 million each but may ultimately reduce the need for other costly therapies and thus afford a net saving...
Though that may seem extraordinary, such major advances in the collection and analysis of patient information are becoming commonplace in modern medicine; technology has made the impossible probable and the unlikely a certainty. Twenty years ago cardiologists mostly guessed at what caused heart attacks. Now young heart doctors, using chemicals...
In addition to TPA, a series of advances in computer-imaging technology have enabled doctors to peer directly into the brain while a stroke is under way. The sharply detailed pictures reveal the type of stroke that is occurring, how far along the stroke has progressed and even whether various...
