Data Acquisition and Image Formationcribed by Kumar. and modified by Edelstein.. Many investigational groups, such as those headed by Mansfield,. Lauterbur,. Crooks,. Hinshaw,. and Pykett,. have made substantial contributions to the development of the techniques required for cost effective signal acquisition.

MRI Hardware, Signal-to-Noise Ratio, and Safety apparatus; the third is the computer apparatus with the analog to digital convertor, array processor, and software for data acquisition and manipulation. Parameters that influence signal-to-noise ratios and a review of safety issues of MRI are also addressed.

Faster MRIr imaging. However, each of these imaging schemes has had to make inevitable trade-offs in signal-to-noise, spatial resolution, and tissue contrast. Several excellent review articles are included for the interested reader..

Magnetic Resonance Artifactstion, and strategies to eliminate them are important to anyone interpreting MRI. Artifacts can create pseudo-lesions (Fig. 8.1), degrade image quality, and instigate inappropriate additional tests or treatments if not recognized.

Congenital Brain Anomaliesmosome abnormality), environmental (ionizing radiation, toxic agents), infection (rubella and cytomegalovirus), and nutrition (hypervitaminosis A) might play roles.. Generally, developmental malformations are either a morphological abnormality (organogenesis) or an abnormal cellular differentiation (histogenesis).
