MAGNETIC RESONANCE IMAGING IN DENTISTRY

Abstract

Magnetic resonance imaging (MRI) is a noninvasive imaging modality that uses magnetic fields and radio frequency waves to produce three-dimensional images. In MRI, signals from protons are used to obtain anatomical images. MRI has disadvantages in the oral and maxillofacial region because it can be adversely affected by body movements, respiration, air in the oral cavity, nasal cells, implants and metal materials during image acquisition. The success of MRI in dentistry, especially in temporomandibular joint (TMJ) evaluations, visualization of salivary glands, lymph nodes, masses in the head and neck, thyroid and parathyroid gland, nasopharynx, soft tissue examinations such as tongue and muscle, has made its use widespread

DİŞ HEKİMLİĞİNDE MANYETİK REZONANS GÖRÜNTÜLEME

Abstract

Manyetik rezonans görüntüleme (MRG) noninvaziv, manyetik alan ve radyo frekans dalgalarının kullanılmasıyla üç boyutlu görüntülerin elde edildiği görüntüleme yöntemidir. MRG’de anatomik görüntüler elde etmek için protonlardan gelen sinyaller kullanılır. Görüntü elde edilmesi esnasında vücut hareketlerinden, solunumdan, ağız boşluğundaki havadan, burun hücrelerinden, implantlardan ve metal malzemelerden olumsuz etkilenebildiği için MRG’nin oral ve maksillofasiyal bölgede kullanım dezavantajları vardır. MRG’nin diş hekimliğinde özellikle temporomandibular eklem (TME) değerlendirmelerinde, tükürük bezlerinin görüntülenmesinde, lenf bezleri, baş boyundaki kitleler, tiroid ve paratiroid bezi, nazofarenks, dil ve kas gibi yumuşak doku incelemelerinde oldukça başarılı olması kullanımını yaygınlaştırmıştır.
