Comparative StudyAutomatic detection and quantification of ground-glass opacities on high-resolution CT using multiple neural networks: comparison with a density mask.
We compared multiple neural networks with a density mask for the automatic detection and quantification of ground-glass opacities on high-resolution CT under clinical conditions. ⋯ Automatic segmentation and quantification of ground-glass opacities on high-resolution CT by a neural network are sufficiently accurate to be implemented for the preinterpretation of images in a clinical environment; it is superior to a double-threshold density mask.

Comparative Study1997 Graduates Speak: initial employment experiences of residency and fellowship graduates.
The American College of Radiology sought to detail the initial employment experience of 1997 diagnostic radiology graduates and recent trends. ⋯ Unemployment remained very low. Some other indicators of the employment market showed improvement. Factors expected to affect employment outcomes-for example, training program quality or having major non-spouse-related restrictions on job location-had surprisingly little effect.

Comparative StudyInterpretation of Emergency Department radiographs: a comparison of emergency medicine physicians with radiologists, residents with faculty, and film with digital display.
We determined the relative value of teleradiology and radiology resident coverage of the emergency department by measuring and comparing the effects of physician specialty, training level, and image display method on accuracy of radiograph interpretation. ⋯ We observed significant differences between the interpretation of radiographs on film and on digital monitors. However, we observed differences of equal or greater magnitude associated with the training level and physician specialty of each observer. In evaluating teleradiology services, observer characteristics must be considered in addition to the quality of image display.

Accuracy of noncompressive sonography of children with appendicitis according to the potential positions of the appendix.
This study evaluates noncompressive sonography of appendicitis in children according to the potential positions of the appendix. ⋯ The noncompressive technique is a valuable tool in sonographic investigation of appendicitis.
