BACKGROUND Conventional computed tomography (CT) images are routinely used for diagnosing patellofemoral instability and are obtained with the patient in a supine position, nonweightbearing, with the knee in full extension, and with leg muscles relaxed. A new portable extremity cone beam CT (CBCT) scanner has been developed that may allow for more accurate diagnosis, as imaging can be performed...

normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 background: computed tomography (ct) scan without contrast is the modality of choice for diagnosis of stroke. however, routine brain ct scan, with linear processing has some limitations in early diagnosis of ischemic stroke. the aim of this study was to evaluate and compare the sensitivity and specificity of processed ct i...

Introduction: Since demand for computed tomography (CT) examinations is growing, patients are exposed more frequently to ionizing radiation. To reduce the dose delivered to patients in each scan, CT technologists can change the image acquisition parameters. However, this reduces image quality. Present study aimed to optimize and reduce radiation dose in a CT of the paranasal si...

objective(s): in clinical practice, approximately 10-25% of post-surgical differentiated thyroid carcinoma (dtc) patients with high serum thyroglobulin (tg) and negative 131i whole-body scan (wbs) have poor prognosis due to recurrent or metastatic lesions after radioactive iodine treatment. the purpose of this study was to evaluate the value of 18f-fdg pet/ct scan in dtc patients with high seru...

background outcome determination of head trauma is important for medical decision-making. to determine the consequences by using ct findings, the marshall and rotterdam criteria were introduced. few studies have been conducted to determine the diagnostic value of the rotterdam criteria. objective this study assesses the diagnostic value of the rotterdam criteria score with early outcome for tra...

background : glenoid bone damages consisting of anterior rim erosion and bony avulsion are very important in decision making for treatment of recurrent dislocation in shoulder joint. this study was aimed to determine the prevalence of these damages in patients with anterior recurrent shoulder dislocation. methods : the study was a cross-sectional study evaluating patients with unstable shoulder...

This study presents medical CT scan image feature analysis, creation of data bank and development of a data mining technique. A dataset of 50 known pancreas digital CT scan images with their clinical diagnosis were composed. All images were subjected for image textual characters (energy, entropy, contrast, homogeneity and correlation), which were statistically calculated in numerical MAT lab en...
