A system for monitoring sound transmission through the human lung is described and the possibility of using this information in order to construct a functional map of the lung is investigated. Lung morphology (structure) may be monitored by using X-rays or computerised axial tomography (CAT). How...
OBJECTIVE: To evaluate the esophageal passage of capsules in clinically normal cats and determine the incidence of prolonged transit or entrapment. ANIMALS: 12 clinically normal adult cats. PROCEDURE: Esophageal transit of barium sulfate-filled capsules was evaluated fluoroscopically. Each cat was examine...

In Magnetic Resonance Imaging, a region of interest is subjected to a strong pulsed magnetic field in a scanner similar to a CAT scanner (which, however, uses X-rays instead of magnetic fields). Under this stimulation, the molecules emit signals which are analyzed into several parameters, each...
Monkeys were each irradiated with both gamma rays and neutrons, at doses ; varying from 70 to 557 r plus 10 to 54 rep, respectively. Irradiation preceded ; testing by st run. Concent 4 yr. Tests were conducted in a modified version of ; the Wisconsin General Test Apparatus, the stimulus...
We present here a relationship between the dose and the yield of symmetric exchanges in peripheral lymphocytes irradiated by gamma-rays in vitro. Heparinized peripheral blood was exposed to ~~ gamma-rays, and cultured according to the whole blood culture method for 52 hr, including colcemid ...

IT"S ALSO VITAL FOR DOCTORS AND PATIENTS TO MAKE SURE THEY UNDERSTAND EACH OTHER. BETTER COMMUNICATION WILL BE EVEN MORE IMPORTANT AS TREATMENTS BECOME MORE COMPLEX. CURRENTLY THERE"S NO SCREENING TEST FOR FINDING LUNG CANCER EARLY.(CHEST X RAYS ALMOST ALWAYS CATCH IT TOO LAT E.)BUT DR. ...
