This study did not show any significant difference in image quality between a standard 2-MP color LCD display and a medical-grade 2-MP monochrome LCD display, neither using the contrast-detail phantom nor in the visual grading study. Our findings are in accordance with several studies that have shown similar performances for color and monochrome displays in a variety of clinical tasks such as brain CT,,2 was acceptable provided that the ambient illuminance was low.

The main purpose of calibrating a monitor according to DICOM part 14 is to obtain similar image presentation on all displays. A calibration distributes the total contrast of the display equally across the entire grayscale and objects will thus be presented with the same contrast regardless of whether they are present in bright or dark parts of the image. When the task is to find known objects in an image, such as targets in a contrast-detail phantom, the window/level controls can be used to optimize image contrast. The display’s contrast characteristics becomes less important and the noise properties become more important—noise from the image detector and noise from the image display. However, this does not mean that calibrating a display is meaningless. Clinical images have little resemblance to images of a contrast-detail phantom in that pathology might be present also in the bright or dark parts of the image. A consistent display of images is even more important when, for example, a current image is compared to a previous image on another display. Any differences between the images should be caused by the imaged object and not by the displays.

The main advantage of medical-grade monochrome displays is their high luminance, which makes it easier to see the entire grayscale from black to white in an image. In a recent report,

The major drawback of color displays is their lower maximum luminance—143 cd/m2 in our study compared to 295 cd/m2 for the monochrome display. A low luminance has been stated to increase the time for diagnosis.

The tests with the contrast-detail phantom showed very small differences in image quality between the two types of displays. There was in fact a larger difference in image quality between the flat-panel detector and the storage phosphor plates (Fig. 2). It might thus be more appropriate to choose a better (more expensive) imaging system such as a flat-panel detector and use (cheaper) color displays than the opposite. Irrespective of the detector being used, there was a large interobserver variability, similar to what has been reported previously.2.

The higher ambient illuminance setting resulted in slightly poorer lesion detection on the 2-MP color display, but resulted in no difference with the 2-MP monochrome display. It is known that ambient illuminance should be low as ambient light elevates the black level of the display,

The visual grading study using clinical images showed significantly higher image quality for the 2-MP monochrome display for reproduction of pedicles and intervertebral joints; and lower for reproduction of spinous and transverse processes. Overall, there was no significant difference between the displays in the visual grading part of the study.

Free adjustment of window width and level was allowed in our study, as that is the way radiologists work in everyday practice. Windowing is easily performed by moving the computer mouse. If this type of image processing is not done, the full potential of digital imaging is not used. We consider image adjustment and manipulation to be a natural part in reading a digital image, and indeed a necessity to view all information in the image, and consequently a comparison between monochrome and color displays without the use of free adjustment of window and level was not included in this study. This is probably one reason why the 2-MP color display performed so well. All information in the image could be placed in the middle (gray) area of the contrast span where the two display types were almost equal. A drawback is that the user’s performance efficiency might be reduced.

To let all PACS stations in a radiology department have the capability to display all types of images, it is necessary to equip them with display units that are able to display also images with color information such as Doppler ultrasound, 3D volume rendered CT images, PET images, and SPECT images. It is costly to furnish an entire radiology department with the more expensive monochrome displays, and color displays might also, for economic reasons, be a better alternative. The new users of digital radiological image information, the clinicians, usually opt for color displays, which may be a conscious cost-saving decision or simply the effect of old habits.

The spatial resolution of the displays was not evaluated specifically in this study because the two displays used in the majority of tests had the same resolution. When used without magnification, the 3-MP monochrome display showed a trend toward higher image quality compared to the 2-MP color display. This is not surprising because the images were scaled to fit the display in that particular test. None of the displays managed to show all of the five megapixels that the test image consisted of, but the 3-MP display did show a larger proportion of the image information than the 2-MP displays.
