The relative value of magnetic resonance imaging (MRI) versus computed tomography (CT) for imaging benign and malignant lesions of the maxilla and mandible was studied in a group of 16 patients. The imaging methods were evaluated for their ability to detect the lesion and define lesion margins, soft tissue extension, and bone involvement. The abnormality was identifiable with both imaging methods. For benign cystic lesions of either the maxilla or mandible (50%), MRI was overall equal to or better than CT. Magnetic resonance imaging was superior to CT in the evaluation of lesion margins and soft tissue extent of disease, whereas it was equal or slightly inferior to CT in lesion detection and in the evaluation of bone involvement. In the imaging of malignant neoplasms (50%), MRI was overall superior to CT in all four categories reviewed. Magnetic resonance imaging also had the highest rate of correlation with clinical findings, either from physical examination or at the time of surgery.
对16例患者组成的队列研究了磁共振成像(MRI)与计算机断层扫描(CT)在上颌骨和下颌骨良恶性病变成像方面的相对价值。评估了这两种成像方法检测病变以及确定病变边界、软组织扩展和骨质受累情况的能力。两种成像方法均能识别异常。对于上颌骨或下颌骨的良性囊性病变(50%),MRI总体上等同于或优于CT。在评估病变边界和疾病的软组织范围方面,磁共振成像优于CT,而在病变检测和骨质受累评估方面,它等同于或略逊于CT。在恶性肿瘤成像(50%)中,MRI在所有四项评估类别中总体上均优于CT。磁共振成像与体格检查或手术时的临床发现的相关性也是最高的。
