Abstract

Aims: The aims of this study were to investigate the bone density in the buccal surface of the maxilla and mandible and to assess the gender difference. Materials and Methods: The study was conducted using computed tomography images for the 46 subjects (25 males and 21 females). Based on computed tomography data, the mean bone density values in Hounsfield units were recorded at 4 different locations from the crest of alveolar bone. Results: The bone density ranged from 795.72- 975.16 Hounsfield units in the maxilla and 837.58- 1339.28 Hounsfield units in the mandible for male and from 742.93- 992.14 and 769.67- 1342.31 Hounsfield units in the maxilla and mandible for female respectively. It was found that the mandibular posterior bone had the highest cortical bone in both sexes, followed by, mandibular anterior, maxillary posterior and maxillary anterior areas in male. In female, the sequence of bone density from highest to lowest was maxillary posterior bone, maxillary anterior and mandibular anterior areas. There was significant difference between males and females in some locations with higher bone densities in males (p<0.05). Conclusions: Bone densities in the buccal maxillary and mandibular areas were presented. They were ranged between 742.93- 1342.31 Hounsfield units in various areas. These data can be used in dental implant treatment planning to avoid associated risk factors

Abstract

ABSTRACT:BACKGROUND:Renal cysts represent notably dilated nephrons or collecting ducts. A cystic kidney is a kidney with three or more cysts. The accuracy of CT diagnosis of typical simple renal cyst approaches 100% but many renal cysts do not fulfill the criteria for simple renal cyst, such lesions vary from simple renal cysts which do not require surgery to renal neoplasms with cystic component that need surgical resection. Contrast-enhanced helical CT scanning has 96% sensitivity and 95% specificity in detecting carcinoma in acquired renal cystic diseases.AIM OF STUDY:To confirm the sensitivity, specificity and performance of the spiral computed tomography (CT) in diagnosis and evaluation of the renal cysts and to study the CT criteria which categorize and separate the renal cystic lesions that require surgery (malignant neoplasm) from those that do not.METHODS:Fifty patients were scanned with spiral CT, 22 of them were males and 28 were females, their ages ranging from 20-70 years with mean age 50 yeas old, these patients undergo CT examinations with and without contrast enhancing material. All the patients were proved to have renal cysts radiologically and symptomatically.RESULTS:The patients presented with cortical simple renal cysts were 16 patients (32% of all the cases). Medullary simple renal cyst were found in 9 patients (18% of the total number of cases). 3 patients presented with autosomal recessive and dominant poly cystic kidney disease (8% of total cases). 1 case found with cystic kidney associated with tuberous sclerosis (2% of total cases). Para-pelvic renal cysts are seen in 7 patients (14% of total cases). Cystic angiomyolipoma (fat density) are seen in 3 patients (6% of total cases). Acquired renal cystic disease is found in 1 patient (2% of total cases). Complicated renal cysts (hemorrhagic) are seen in 2 patients (4% of total cases). Medullary cystic diseases were found in 2 patients ( 4% of total cases). Multicystic dysplastic kidney was found in 1 patient (2% of total cases). Malignant Cystic kidney lesion (cystic renal cell carcinoma) was found in 1 patient (2% of total cases). Females are more affected than the male, 28 females (56%) while the affected males were 22 (44%). The more involved age group was between 50-59 years old, they were 15 patients (9males and 6 females). The left kidney (34%) is more involved than the right kidney (32%), while both kidneys were involved in (34%) of the cases.CONCLUSION:The spiral CT scan is the most sensitive imaging modality useful in diagnosis of cystic kidney and it is of valuable importance in evaluation and categorization of cystic renal masses in attempt to separate the lesions that require surgical resection from those do not

Abstract

Background: Implantology is a fast growing area in dentistry. One of the most common issues encountered in dentalimplantation procedures is the lack of adequate preoperative planning. Conventional radiography may not be ableto assess the true regional three-dimensional anatomical presentation. Multi Slice Computed Tomography providesdata in 3-dimentional format offering information on craniofacial anatomy for diagnosis; this technology enables thevirtual placement of implant in a 3-Dimensional model of the patient jaw (dental planning).Patients, Material and Methods: The sample consisted of (72) Iraqi patients indicated for dental implant (34 male and38 female), age range between (20-70) years old. They were examined during a time period started from December2012 to April 2013. All the patients who subjected to implant treatment depending on the pre-operative panoramicradiograph were referred Al-Kharkh General hospital, spiral CT scan Department, for postsurgical assessmentevaluate the angulation of fixture in relation to the angulation of bone in coronal and sagittal sections by usingMulti-Detector Computed Tomography.Results: The present study showed that the angulation of implant affected by age, sector, and tooth position in thesame jaw, and not affected by gender.Conclusion: Multi-Slice Computed Tomography provides a great understanding about bone angulation, it necessaryas a diagnostic tool for treatment planning pre and post-operatively

Abstract

Background: Determination of local bone mineral density (BMD) with cortical thickness and bone height may offer acomprehensive description of the bone the surgeon will encounter when he or she actually sets the implant.Quantitative computed tomography (CT) (i.e., quantitative interpretation of values derived from Hounsfield units witha suitable calibration procedure) is the modality of choice to determine BMD. The aim of the present clinical study isto determine the local bone density in dental implant recipient sites using computerized tomography.Material and method: The sample consisted of (72) Iraqi patients whom referred to Al-Kharkh General hospital, SpiralCT scan Department for bone quality and quantity assessment after one week of dental implants insertion, theaverage of bone density was measured for 120 areas indifferent sectors of maxilla and mandible in Hounsfield unite.Results: As a mean, males show higher bone density than females, decreased with increased age significantly,mandible show significantly higher bone density than maxilla. Maxilla revealed no significant difference between thethree sectors, while in the mandible there was significant difference between posterior sector (613.1HU)and bothanterior (821.3 HU) and premolar sectors (779.6 HU) with no significant difference between anterior and premolarsectors.Conclusion: CT-Scan may provide a valuable aid to predict bone quality at potential implant sites and could beused to assess the change of bone density around dental implants

Abstract

Background: Genioglossus advancement is a surgical procedure to advance the tongue in some patients withobstructive sleep apnea syndrome.The important step in this procedure is that of accurately capturing the bonesegment attached to the genioglossus muscle to avoid complications such as mandibular fracture, devitalization ofthe inferior incisor roots, and incomplete incorporation of the genioglossusMaterials and Method: Computed tomography scans were taken for 53 Iraqi adult patients (28 male and 25 female)range from (18-35) years with skeletal class I classification and intact anterior mandible dentition included in this studyusing sagittal and axial sections. The measurements were done for genial tubercle and anterior mandibular region.Results: The mean values of some measurements weresignificantly higher in males than in females. The effect ofgender difference was evaluated as a strong effect. The mean value of the other measurements slightly higheramong males compared to females, but the difference fail to reach the level of statistical significance. The effect ofgender difference on this parameter was evaluated as a moderately strong effect.The results showed that there wasno effect of age on all selected measurements in male and female. All selected measurements showed nostatistically significant linear correlation with the age.Conclusions: The variable position and dimensions of this bone segment among patients suggest the need for CTbefore attempting genioglossus advancement for exact localization, avoiding the expected surgical complication

Abstract

Background: with the dramatic increase in the use of chest computed tomography (CT) for diagnostic or screening purposes, incidental breast lesions faced more frequently; while most of these incidental breast findings are benign; nevertheless, breast cancer be existing.Objectives: to determine the imaging characteristic of incidentally detected breast lesions in routine chest computed tomography and to review the outcome of further assessment of these abnormalities.Patients and methods: a prospective study performed on (33 patients) during the period from October 2014 to November 2015 in AL Shaheed Ghazi Al Hariri hospital, Baghdad teaching hospital, and Radiology Institute at Medical city complex, Baghdad. All patients were female and their ages ranging from (18-74) years. Then breast lesions found incidentally at CT scan identified and their CT features analyzed and include number of lesions, size, location, shape, margin characteristics, and density of the lesion and associated calcification. Most of these patients with incidental breast findings were followed up by performing breast ultrasound (US) and/or mammography in oncology teaching hospital (according to their age) and according to breast imaging and reporting data system (BIRADS); BIRAD- IV and V lesions followed by cytopathological examination and final results were recorded.Results: during the study period, a total of 39 incidental breast lesions were identified on chest CT scan among those 33 patients because some patients had multiple lesions. The mean age of patients for malignant lesions was (53±6.1 years) and for benign lesions was (43.21±0.8years). 25.6%, of incidental, breast lesions found to be malignant and 74.4% found to be benign. Malignant incidental breast lesions tend to have an irregular shape, ill-defined margin and have soft tissue attenuation.Conclusion: Although CT scan is not the primary procedure for the breast imaging, but it can show a significant complementary role in the evaluation of the breast with ultrasound and mammography. A careful review of the breast and accurate characterization of incidental breast lesions (IBL) would highlight the radiological reports, it would achieve appropriate management for the patients, and this would improve survival. Although some of the findings of benign and malignant breast lesions on CT scan do overlap to some degree, we can conclude that an irregular shape and ill-defined margin are important features that go with malignant breast lesions.Key words: incidental, breast, computed tomography.
