The aim of this study is to determine the correlation between computer-assisted diagnosis (CAD) of benign bone tumours (BBT) and their histological type. Patients and method. Altogether 120 patients were included in two groups. The retrospective group comprised 68 patients in whom the histological type of BBT was known prior to computer analysis. The prospectivegroup comprised 52 patients in whom the histological type of BBT was unknown prior to computer analysis. Computer program was efficient and easy to use. Results. Average percent of histological type confirmed with CAD in the retrospective and prospective groups was 72.06% and 76.92%, respectively. Histological confirmation of CAD in specific BBT was 91.42% for enchondroma, 96.15% for osteoid-osteoma, and 98.08% for osteochondroma. Significantly lower percentage of CAD confirmation of fibroma, chondromixoid fibroma, osteoclastoma, desmoplastic fibroma and osteobalstoma due to their adverse biological character or complex anatomic localization is understandable. Conclusions. The results speak in favour of the assumption that computer assisted diagnosis of bone tumours program may improve the diagnostic accuracy of the examinerIzhodišča. Namen raziskave je bil določiti uspešnost diagnosticiranja benignih kostnih tumorjev z računalnikom glede na različno histološko zgradbo tumorjev. Bolniki in metode. V raziskavo smo vključili 120 bolnikov in jih razdelili v dve skupini. V retrospektivni skupini j e bilo 68 bolnikov, ki je imelo pred računalniško analizo že znano histološko diagnozo. V drugo, prospektivno skupino pa je bilo vključenih 52 bolnikov, ki še niso imeli znanehistološke diagnoze. Uporabljali smo uporabnikom prijazen računalniški program. Rezultati. V retrospektivni skupini smo s pomočjo računalnika potrdili histološko diagnozo benignega kostnega tumorja v povprečju v 72,06%, v prospektivni skupini pa v 76,92%. Glede na posamično vrsto benignega tumorjasmo bili najbolj natančni pri enhondromih (v 91,42%), osteoidosteomih (v 96,15%) in osteohondromih (v 98,08%). Značilno nižji procent pravilne diagnoze smo dosegli pri fibromih, hondromiksoidnih fibromih, osteoklastomih, dezmoplastičnih fibromih in osteobalstomih, kar si razlagamo z različnimi biološkimi značilnostmi in anatomsko lokalizacij o teh tumorj ev. Zaključki. Rezultati so potrdili pričakovanje, da lahko s pomočjo računalnika izboljšamo natančnost slikovne diagnostike pri ugotavljanju benignih kostnih tumorjihTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaDruštvo radiologije in onkologije
