Abstract:
:A total of 24,560 fetal biparietal measurements were made using the B-scan technique. The increase in biparietal diameter was compared in normal pregnancies, in those complicated by diabetes or toxemia, and in fetuses thought to be small for dates. Only the last of these groups demonstrated a statistically significant difference.

RADIOLOGY文献大全abstract::The theories of decision processes and signal detection provide a framework for evaluation of observer performance. Some radiological procedures involve a search for multiple similar lesions, e.g., plain radiographic examinations for gallstones or pneumoconiosis. Presuming knowledge of the conventional ROC curve for d...

abstract::Irradiation of the orbit is often associated with substantial dose inhomogeneity resulting from the insertion of lens blocks. We postulated that such dose inhomogeneity, which often exceeds 40%, could be halved by the use of two pairs of wedged beams, one angled in the sagittal plane and the other in the commonly empl...
