Abstract
Cilj istraživanja: Usporediti kvalitetu prikaza mamografske snimke na običnim i dijagnostičkim monitorima različitih specifikacija i utvrditi važnost ovih čimbenika u ranoj dijagnostici raka dojke. Nacrt studije: Presječna studija Materijali i metode: Podaci su prikupljeni ispitivanjem 61 monitora iz 7 različitih zdravstvenih ustanova te statistički obrađeni programom MedCalc 20.026. Kao zlatni standard u procjeni kvalitete medicinskih dijagnostičkih i običnih monitora koristio se Artinis CDMAM 3.4. fantom. Promatrač je rezultate ispitivanja svakog monitora zabilježio na obrazac za bodovanje te potom usporedio s evaluacijskim obrascem iz čega proizlazi izračun za kvalitetu slike. Rezultati: Značajno bolja kvaliteta slike je kod medicinskih dijagnostičkih monitora u odnosu na obične monitore (55,6 % vs. 43,9 %). Najbolja kvaliteta slike je u monitora razlučivosti 2048 x 2560 (62,4 %). Signifikantne su razlike u kvaliteti slike između svih vrijednosti s obzirom na razlučivost. Monitori s nijansom sive 10-bita značajno imaju bolju kvalitetu slike u odnosu na monitore koji imaju nijansu sive 8-bita (60,5 % vs. 44,6 %). Znatno je lošija kvaliteta slike kod monitora u boji u odnosu na one koji nisu (45,4 % vs. 60,7 %). Bolja kvaliteta slike je u monitora s IPS panelom u odnosu na monitore s TN panelom (54,4 % vs. 42,4 %). Zaključak: Medicinski dijagnostički monitori visoke rezolucije imaju bolju kvalitetu slike, što pomaže boljoj identifikaciji mikrokalcifikacija bitnih za rano otkrivanje raka dojke. Boljoj kvaliteti slike pridonose veća rezolucija monitora, veća dubina sivih tonova te vrsta panela.
Abstract (english)
Objectives: To compare the image quality of mammography on consumer and medical graded monitors of different specifications and establish the importance of these factors in the early diagnosis of breast cancer. Study Design: Cross-sectional study. Materials and Methods: Data were collected by examining 61 monitors from 7 different healthcare institutions and statistically processed by MedCalc 20.026. Mammography image of Phantom Artinis CDMAM 3.4 was used as the gold standard in the assessment of the quality of medical and consumer graded monitors. The observer recorded the test results for each monitor on a scoring form, compared it with the evaluation form, and calculated an image quality score. Results: Significantly better image quality proved to be observed is in medical graded monitors compared to consumer graded ones (55.6 % vs. 43.9 %). The best image quality is in a monitor with resolution of 2048 x 2560 (62.4 %). There are significant differences in image quality between all values with respect to resolution. 10-bit grayscale monitors have significantly better image quality than 8-bit grayscale monitors (60.5 % vs. 44.6 %). The image quality of color monitors is significantly lower than that of non-color monitors (45.4 % vs. 60.7 %). The image quality is better in monitors with IPS panel compared to monitors with TN panel (54.4 % vs. 42.4 %). There is no significant difference in image quality with respect to the backlight. Conclusion: High-resolution medical graded monitors have better image quality which helps in identifying microcalcifications essential in early breast cancer detection. Higher monitor resolution, greater grayscale depth and panel type contribute to better image quality. An advantage was observed in monochrome monitors while significant differences between LED and CCFL panel types were not found.
