background paranasal sinus ct has high sensitivity and specificity for sinusitis. however, this modality is costly and involves greater radiation exposure than plain radiographs. objectives we tried to compare 10-cut limited ct scan and standard ct scan in the diagnosis of sinusitis. materials and methods we conducted a cross sectional case series from august to december 2010 on 150 patients wi...

Objectives: Presence/absence of cervical lymph node metastasis plays a critical role in prognosis and survival of patients with oral squamous cell carcinoma (SCC). This study was designed to assess the diagnostic accuracy of computed tomography (CT) scan for detection of cervical lymph node metastasis in oral SCC in comparison with histopathological analysis after neck dissection Methods: In...

Traditionall y, the fi xed brain is sliced into sections in a coronal or horizontal plane for neuropathologic analysis. Computed tomography (CT) requires a reconsideration of this procedure and development of methods that allow for correlation of anatomopatholog ic aspects of lesions with correspond ing CT scan images [1 , 2]. This has been proposed by many authors and several techniq ues for a...

BACKGROUND Percutaneous sacro-iliac (SI) screw fixation represents a widely used technique in the management of unstable posterior pelvic ring injuries and sacral fractures. The misplacement of SI-screws under fluoroscopic guidance represents a critical complication for these patients. This study was designed to determine the prevalence of sacral dysmorphia and the radiographic anatomy of surgi...

Plagiocephaly (oblique skull) is premature fusion of one of the coronal sutures. Frontal plagiocephaly is a rare congenital deformity in the skull that is the most complicated form of craniosynostosis to treat. Examination of all sutures is necessary for diagnosis of craniosynostosis In this article, a 10-month-old, healthy girl with deformity of the right forehead and orbit that is caused by f...

A 30-year-old patient sustained the fracture in a motorcycle accident. A triplane-type of fracture of the distal femur was confirmed by CT scan. The trochlear fragment was reduced anatomically and was stabilized with 6.5mm cannulated screws. Once reconstruction of the coronal plane fracture was performed, the split lateral condylar fragment was fixed with a cannulated screw to the medial fragme...

methods multidetector ct-scan and explorative laparotomy of the patients with blunt abdominal trauma were assessed retrospectively. characteristics of the injuries were categorized on the basis of the american association for the surgery of trauma (aast) grading system and the findings were analyzed using kappa test. results the findings of 35 patients were analyzed. according to the kappa test...

Background: Posterior superior alveolar artery (PSAA) is branch of the maxillary artery. It usually supplies the lateral wall of the sinus and overlying membrane. Evaluation and awareness of the anatomy of maxillary sinus before surgery is crucial to avoid surgical complications. The aim of this study is to examine the location and diameter using computerized tomography (CT) scans. Materials an...

Post stroke dementia is one of the most common complications of stroke that is preventable and relatively treatable too. The purpose of the study is comparison between the positive findings in brain CT scan and brain perfusion SPECT. 15 patients who were complicated by dementia after cerebrovascular accident and also 5 patients as a control group enrolled in this study. Brain CT scan and ...
