contralateral pneumothorax crossing the midline in a patient with autopneumonectomy can mimic bilateral pneumothoraces on chest radiography. in this study, we report a rare case of right pneumothorax mimicking bilateral pneumothoraces in a patient with left autopneumonectomy. a 37-year-old man complained of progressive chest pain and dyspnea. the initial chest radiography revealed visible visce...

conclusions our study shows in terms of figures that measurements of features of the temporal bone made from spiral ct scan images and those directly obtained during surgery are similar to an adequate extent. results twenty cases were included. in the three measurements performed in this study, only the first parameter (distance between the canal and the sigmoid sinus) was significantly differe...

to our knowledge, bilateral supernumerary kidney is a very rare renal abnormality and there are five cases presented in the literature. it is difficult to diagnose supernumerary kidney and clinicians have not detected most cases preoperatively. laboratory and imaging studies were acquired and carefully examined. the normal laboratory tests were found. emergency ultrasonography was performed and...

background: paratracheal air cysts (pacs) are extraluminal collections of air mostly located adjacent to the right of the trachea at the level of the thoracic inlet. although, pacs are usually asymptomatic, the lesions do occasionally cause complications such as chronic cough, difficult intubation, and right-sided recurrent laryngeal nerve palsy. the purpose of the present study was to demonstr...

objectives: new digital two-dimensional imaging systems are considered as an easily accessible modality for sinonasal evaluation. the aim of this study was to assess the diagnostic efficacy of digital waters’ and caldwell’s radiographic views for evaluation of sinonasal area. materials and methods: a total of 273 patients fulfilling the inclusion criteria were enrolled in this descriptive-analy...

objective: cone beam computed tomography (cbct) is applied for the imaging of the maxillofacial and dental structures, particularly for surgical treatments and dental implants. the aim of this study was to assess the effect of slice thickness on the accuracy of cbct linear measurements. methods: in this diagnostic accuracy study, forty-two titanium pins with the same dimensions were inserted in...

abstract introduction: temporomandibular joint disorders (tmd) are the most common disorders of the jaw, and despite their clinical importance, they are not completely understood. this study was aimed to evaluate the changes of temporomandibular joint (tmj) on cone beam computed tomography (cbct) images in disc displacement vs. osteoarthritis of the tmj. methods: in this study, 45 patients, inc...

background: coronary computed tomography angiography (ccta) is a well-known method for evaluating anatomic coronary stenosis, but the reliability of ccta to predict cardiovascular events is an issue of controversy. materials and methods: in this prospective observational study, 58 patients with acute chest pain and low-to-moderate risk were selected and ccta was performed on them. during follow...

background and aims. because of increasing concerns about surgeries in the anterior maxilla, including implant placement, it is necessary to examine the morphology of the nasopalatine canal and its surrounding bones. this study aimed to analyze the shape and position of the nasopalatine canal and incisive foramen using cone-beam computed tomography (cbct). materials and methods. cbct images of ...

the pomegranate seed oil (pso), containing 17-α-estradiol, is one of the newly found phytosterols with synergistic health effects on estrogen related physiological conditions. herein, pso was assessed for its potential improving effects on bone characteristics in a rat model of menopausal syndrome. three month old non-pregnant female wistar rats (n = 30) were either sham-operated (sham) or ovar...
