BACKGROUND AND PURPOSE: Aging is recognized to originate from a diversity of
mechanisms that blur the limits between normal and pathologic processes. The purpose of this …

Because of the limited number of projections, the mathematic reconstruction formula of the
filtered backprojection (FBP) algorithm may create an artifact that streaks reconstructed …

In this study, we investigate the application of the fuzzy clustering to the anatomical localization
and quantitation of brain lesions in Positron Emission Tomography (PET) images. The …

Factor analysis of dynamic structures (FADS) facilitates the extraction of relevant data, usually
with physiologic meaning, from a dynamic set of images. The result of this process is a set …

The metabolism of the human masseter muscle was investigated using phosphorus (31p)
magnetic resonance spectroscopy (MRS) during long periods of exercise and recovery. …

Extraction of the Left Ventricle (LV) contours is essential in the quantitative analysis of
cardiac function. We present a new method that employs Fuzzy Isodata (FI) and conne nents …

While most of the methods for quantitative regional cerebral blood flow (rCBF) determination
in man requires expensive fast devices, a method is proposed using single photon …

cardiac function. We present a new method that employs Fuzzy Isodata (FI) and connected …

Glial-cell-line-derived neurotrophic factor (GDNF) is a potent neurotrophic factor for adult nigral
dopamine neurons in vivo. GDNF has both protective and restorative effects on the nigro-…

The philosopher Jean-Jacques Rousseau burst unexpectedly onto the eighteenth-century
literary scene as a provocateur whose works electrified readers. An autodidact who had not …
