The usefulness of free dicom viewers in rhinologic practice.

ABSTRACT

Indroduction The planning of the course of surgery in patients with paranasal sinus disorders requires the meticulous evaluation of computed tomography (CT) scans. However, ENT doctors still often receive unsatisfactory DICOM images, which require multiplanar reconstruction (MPR). THE AIM: The objective of the present study was to evaluate and test DICOM viewers with MPR function currently available on the Internet for free. MATERIAL AND METHODS: Detailed Internet searches and analysis of databases were carried out to find the maximum number of browsers. Available software was downloaded to assess, qualitatively and quantitatively, the parameters and functions useful in rhinologic practice. Additionally, a questionnaire was developed in order to ascertain the expectations and habits of ENT doctors in relation to DICOM browsers and CT scan evaluation. RESULTS AND CONCLUSIONS: Among the hundreds of browsers, 17 programs were chosen to be included in the final comparison. The outcomes of the survey proved that many free DICOM tools are effective alternatives to commercially available programs. However, the results do not enable us to predict precisely which tool will meet the needs of each physician. The survey among ENT doctors highlighted their limited awareness of software with MPR functions, in particular those that scored best in the test.
