Abstract

In this research, it is tested a line profile method, a method of CR image quantization which has potential as a tool for radiologist in interpretation the radiology images. The line profile method provides additional quantitative reference considerations with high objectivity, as well as detects abnormalities that may not visible visually. Images of paranasal sinuses examination from 45 pediatric patients at the age ranges of 1-5 years, 5-10 years and 10-15 years were grouped by radiologists' anatomical interests, namely inferior nasal concha, maxillary sinuses, frontal sinuses, sphenoidal sinuses and ethmoid sinuses. Test lines were positioned with respect to each image's bony landmarks, followed by quantization performed by generating a profile of pixel value along each test lines using ImageJ. The profiles were analyzed both qualitatively and quantitatively. Whereas qualitative analysis compared the line profile of patients diagnosed with and without abnormality by the radiologist, quantitative analysis compared the line profile of images with abnormality with a baseline generated from images without abnormality. Qualitative assessment shown that the method can be applied for anatomical interests of inferior nasal concha, maxillary sinuses, and frontal sinuses with an agreement to radiologist diagnosis of 82%, 81% and 100%, respectively. On the other hand, quantitative analysis demonstrated a feasibility of this method on anatomical interests of maxillary sinuses and frontal sinuses with 89% and 50% agreement to radiologist diagnosis for maxillary and frontal sinuses, respectively.
