MSCT combined with Dental software in jaw bone tumor or tumor lesions imaging studies
The first purpose.
This study applies PHILIPS offerings 64 Dental layer spiral CT reconstruction functions such as Planning software combined with MPR, VR in our hospital 98 cases of oral maxillofacial tumors and tumor lesions of MSCT image post-processing to observe, classify their imaging characteristics statistics and summary analysis, aims to reveal the characteristics of pathological changes and identify key points, to provide reference for the diagnosis and treatment of jaw bone tumors or tumor lesions.
the second,method:
1, select a February 2013 in July 2008 in our hospital hospitalization jaw tumors and tumor lesions in patients 98 cases as the research object, benign lesions 70 cases including tooth source sex Angle of cystic tumors 20 cases, 14 cases of ameloblastoma, tooth source sex cysts in 11 cases (including teeth cyst in 4 cases, 7 cases of periapical cyst), tooth tumor in 2 cases, cementoblast tumor, of source sex fibroma and myxoma in 2 cases, 9 cases of simple bone cyst, 4 cases were abnormal bone fibre hyperplasia with shaofu zhuyu tang, ossifying fibroma, 2 cases, vascular malformation and eosinophilic granuloma in 1 case; 28 cases of malignant lesions including 2 cases of malignant ameloblastoma, oral maxillofacial squamous cell carcinoma (3 cases), gum source 10 cases of malignant tumors, malignant tumors involving the maxilla, 9 cases of maxillary DouYuan sex, multiple myeloma and plasma cell tumor in 2 cases. Preoperative MSCT scan, in which 43 underwent enhanced scanning, the original volume to 1 mm thin layer scanning data reconstruction, using workstation Dental Planning to post-processing, and volumetric representation technology (VR) and multi-plane reorganization method comparative analysis (MPR) images, and the lesions imaging features were analyzed.
2.Image data analysis
In our hospital 98 cases of oral maxillofacial tumors and tumor lesions imaging data for system review, combined with the tooth source sex tumour of the WHO classification (2005) new, all lesions imaging characteristic classification statistics and summary analysis, mainly from the following several aspects are analyzed: lesion location, the expansion of the jaw, lesions within the density and the presence of high density zones within the lesion, lesions with shine dentition, adjacent root involvement, the integrity of the bone cortex around, adjacent soft tissue involvement, mandible lesions observed mandibular canal compression damage situation, summarize the main points the diseased image characteristics and its identification.

MSCT combined with dental software jaw tumors or tumor-like lesions in imaging studies
First, the purpose
In this study, Philips Brilliance 64-slice spiral CT Dental Planning software combines MPR, VR reconstruction MSCT image of our hospital 98 cases of jaw bone tumors and tumor-like lesions post-treatment observation, classification statistics and summary of each imaging features analyzed to reveal the characteristics of the lesions and identification of key points, to provide a reference for the diagnosis and treatment of jaw tumors or tumor-like lesions.
Second, the method
1, select the July 2008 February 2013 in our hospital jaw tumors and tumor-like lesions in 98 patients for the study, including 70 cases of benign lesions including odontogenic keratosis cystic tumor 20 cases, into 14 cases of ameloblastoma, odontogenic cyst 11 cases (dentigerous cyst in 4 cases, periapical cyst 7 cases), two cases of odontoma Cementoblast cell tumor of odontogenic fibroma and myxoma in 2 cases , nine cases of simple bone cyst, fibrous dysplasia of disease
4 cases, 2 cases of ossifying fibroma, vascular malformations and eosinophilic granuloma 1; 28 cases, including 2 cases of malignant ameloblastoma, jaw squamous cell carcinoma in 3 cases of malignant lesions, gum-induced malignant tumors 10 cases of maxillary sinus-induced malignant tumors involving the mandible in 9 cases, 2 cases of multiple myeloma and plasma cell tumors. Preoperative MSCT scan, 43 cases enhanced scan, the original volumetric scan data 1mm thin layer Renewal, the use of post-processing workstation Dental Planning, and volume rendering (VR), multi-planar reconstruction (MPR) image analysis, and lesion imaging features for statistical analysis.
2, image data analysis
WHO (2005) classification, our hospital 98 cases of jaw bone tumors and tumor-like lesions of the imaging data system review, combined with odontogenic tumor imaging features of each lesion classification statistics and analyzed, mainly from the following an analysis of: the lesion location, the degree of swelling of the jaw, lesion density and lesion and whether the high-density areas, lesions unimpeded tooth the neighboring root involvement, integrity of cortical bone around the adjacent soft tissue involvement, the mandibular lesions observed mandibular canal compression failure, summed up the image of each lesion characteristics and identification of key points.
