Background: Lung diseases and lung cancer are among the most dangerous diseases with high mortality in both men and women. Lung nodules are abnormal pulmonary masses and are among major lung symptoms. A Computer Aided Diagnosis (CAD) system may play an important role in accurate and early detection of lung nodules. This article presents a new CAD system for lung nodule detection from chest comp...
effect of clinical in formation on brain ct scan in t erpretation: a blin ded double crossover study
errors and variations in interpretation can happen in clinical imaging. few studies have examined the biased effect of clinical information on reporting of brain ct scans. in a blinded double crossover design, we studied whether three radiologists were biased by clinical information when making ct scan diagnosis of the brain. three consultant radiologists in three rounds with at least a one-mon...
تشخیص ساختمان داخلی فرش دستباف با استفاده از تصاویر سیتیاسکن میکروفوکوس حاصل از تبدیل رادون معکوس
In addition to medical recognition applications, X-ray CT-scan images are increasingly found to have more innovative and widespread applications. Due to the ability of producing high resolution and high contrast images from soft tissues with low attenuation coefficients, the usage of X-ray micro-focus source, which has a very small focal point (in the range of micrometer), plays an important ro...
UNLABELLED The purpose of this study was to investigate the clinical usefulness of PET/CT or CT-attenuated PET in the evaluation of patients with oral cavity cancer (OCC) in whom dental artifacts distorted the conventional CT or MR images of the oral cavity. METHODS A PET/CT scan, in addition to a CT or MRI scan, was performed in 69 patients with OCC who had dentures or dental implants. A tot...
Introduction: Due to the use of ionizing radiation in the CT scan, optimal parameters should be used to reduce the risk of cancer in patients who are constantly exposed to X-rays. The aim of this study was to optimize the parameters used in CT scan of cervical vertebrae and neck soft tissue with minimal loss of image quality Materials and Methods: In this s...
Incidental extra-osseous uptake of 99mTc-MDP on bone scintigraphy has been frequently reported in the literature; however, calcification of the psoas muscle is a rare condition, which has been reported on magnetic resonance (MR) and computed tomography (CT) imagings. Here we report a 67-year-old woman with acute paraplegia and low back pain who was referred for a 99mTc-MDP...
conclusions in cases of pontaneous pneumothorax, chest x ray and computerised tomographic scan have limitations. ct scan in combination with video assisted thoracoscopic surgery improves diagnostic accuracy and facilitates appropriate management of non-resolving spontaneous pneumothorax. objectives a 15 year old boy presented to the referring hospital with a right sided spontaneous pneumothorax...
trauma is the most common reason in 1-34 years olds. in patient with multiple traumas, the head is the most common involved part. the importance of computed tomography (ct scan) in diagnosis of brain trauma is well established and ct of the brain is a choice method. finding lesion in brain traumatic patient is very important so goal of this study is finding of brain ct scan in traumatic patient...
An approach for automatic classification of computed tomography (CT) medical images is presented in this paper. A vast amount of CT images are produced in modern hospitals due to advances of multi-slice Computed Tomography (CT) Scan which handles up to 64 slices per scan. So, an input image based automatic medical image retrieval system is now a necessity. In this paper, Coiflet wavelets are us...
