Comparative evaluation of MDCT and 1.5T MRI in radiographically detected jaw lesions

Abstract

Background: Jaw lesions comprise a broad spectrum of odontogenic and nonodontogenic lesions. They may be cysts, tumors, or tumor-like lesions. Clinical presentation of this vast spectrum of pathology is nonspecific. On imaging, they may be classified as radiolucent, mixed, or radioopaque. Based on this broad categorization of imaging appearances and few specific imaging characteristics if present, it may be possible to diagnose a particular jaw lesion or at least reach a narrow differential diagnosis. Aim & Objective:1. Comparative evaluation of MDCT and 1.5T MRI in radiographically detected jaw lesions.2. Study roll of MDCT and 1.5T MRI in diagnosis of jaw lesions Methodology: Study design: A Prospective Study. Study setting: Radio diagnosis department of Basaveshwara Medical College and Hospital, Chitradurga. Study duration: from July 2022 to June 2023. Study population: The
study population included all the cases with jaw lesions patients admitted at a tertiary care center Sample size: 50 Results: Majority of cases found in 46- 65 years age group 17 (34%) followed by above 65 years age group 15 (30%), 31-45 years 13 cases (26%) and 5 cases in 18-30 years age group. Most of cases were males 30 (60%) and 20 females (40%). MDCT shows most of cases were Ameloblastoma 12 followed by Keratocysticodontogenic tumor 10, Periapical cyst 7, Osteomyelitis 6, Dentigerous cyst 4, Odontoma 4, Cementoblatsoma 2, Osteogenic Sarcoma 2, Osteochondroma 2. 1.5T MRI shows majority of cases were Ameloblastoma 12 followed by
Keratocysticodontogenic tumor 9, Periapical cyst 8, Osteomyelitis 6, Odontoma 5, Dentigerous cyst 4, Cementoblatsoma 2, Osteogenic Sarcoma 2, Osteochondroma 2

Conclusion: MRI could be effectively useful to the typing of different expansive lesion, and to evaluate the possible infiltration of the soft tissue. This information is decisive in the differential diagnosis between the benign lesions and major aggressive odontogenic tumours and in the surgical planning.
