Юрак МРТ ва эхокардиография туғма юрак нуқсонлари (ТЮН) бўлган беморларни тасвирлашнинг анъанавий асосий усуллари ҳисобланади. Бироқ замонавий КТ сканерлари фазовий ва вақтинчалик аниқликнинг сезиларли яхшиланиши туфайли ушбу соҳада КТ диагностикасининг имкониятларини кенгайтирди. Тадқиқот протоколи тахмин қилинаётган нуқсон турига, аввал бажарилган жарроҳлик аралашувларига, беморнинг ёши ва ҳамкорлик даражасига боғлиқ бўлиб, айниқса педиатрия беморларида нурланиш юкламасини камайтириш стратегияларини қўллаш жуда муҳимдир. ТЮНни баҳолашда кетма-кет сегментар ёндашув кенг қўлланилади, ҳамда тўғри талқин қилиш учун радиолог махсус КТ протоколлари, ТЮНнинг мураккаб анатомияси ва морфологияси, шунингдек туғма нуқсонларни тўғрилашга оид жарроҳлик усулларини чуқур билиши лозим.
