Magnetic resonance spectroscopy provides biochemical and metabolic information about tumors and the normal brain. 17 Blood oxygen level–dependent functional MRI is used for neurosurgical planning and neurologic risk assessment in patients with brain tumors. 18 Positron emission tomography (PET), a non-invasive and functional imaging technique, is used in assessing diagnosis, grading cerebral gliomas, and differentiating between tumor recurrence and radiation necrosis. 19 PET can also be used to predict the response to chemotherapy versus radiochemotherapy. 20
Q. what is "pulmonary edema" and what are the risks? my Dr. told me I'm in a risk group for pulmonary edema, he tried to explain what it is but i didn't understand fully...if someone may give me a brief explanation- I'll appreciate it! A. pulmonary edema occurs when, lets say, your heart left ventricle stops working properly and your right ventricle works fine. that means your lungs getting lets presume- 1 liter of blood -but your left ventricle can pump out of it only 990 ml. that means you have high blood pressure in your lungs and fluid comes out of blood vessels and fills your lungs, making it harder and harder breathing.

Vinegar R, Truax JF, Selph JL, Johnston PR, Venable AL, McKenzie KK "Antiserotonin agents inhibited the hypoalgesia and part of the edema. These findings and histological observations suggested that dermal mast cells were injured by C. The hyperalgesia and part of the edema were sensitive to arachidonate cyclooxygenase inhibitors (AACOIs). It is speculated that injured mast cells metabolize arachidonic acid and reactive intermediates, not prostaglandins, mediate the NPIR hyperalgesia and part of the edema." "Arachidonic acid metabolism by neutrophils is speculated to produce the mediators of phagocytic inflammatory (PI) edema and hyperalgesia."
