Partial Volume Effect and Correction for 3-D Color Flow Acquisition of Volumetric Blood Flow

Does cerebral blood flow decline in healthy aging? A PET study with partial-volume correction.

UNLABELLED It remains a matter of controversy as to whether cerebral perfusion declines with healthy aging. In vivo imaging with PET permits quantitative evaluation of brain physiology; however, previous PET studies have inconsistently reported aging reductions in cerebral blood flow (CBF), oxygen metabolism, and glucose metabolism. In part, this may be because of a lack of correction for the d...

Effects of Mobile Phone Radiation on Surface Tension and Volume Flow Rate of Human Blood groups

Introduction: The great use of electrical appliances in different life applications is one of the most obvious concerns because of its possible health drawbacks. These investigation reports results of electromagnetic field effect emitted from mobile phones on some biophysical parameters of human blood belonging to blood groups A, B, AB & O collected from the normal persons. The parameters obser...

Measurement of Flow and Volume of Blood

One of the primary measurements the physician would like to acquire from a patient is that of the concentration of O2 and other nutrients in the cells. Such quantities are normally so difficult to measure that the doctor is forced to accept the second-class measurements of blood flow and changes in blood volume, which usually correlate with concentration of nutrients. If blood flow is difficult...
