introduction : the objective of this study was to give a description of the most prominent atypical radiological presentations of lung hydatidosis. materials and methods: all patients diagnosed with pulmonary hydatidosis by surgical exploration were included in this study. standard chest roentgenogram and computed tomography ct) were evaluated before surgery for lung cysts or unknown lesions. r...

introduction: motion artifacts are a common problem in pediatric radiographic studies and are a common indication for pediatric procedural sedation. this study aimed to compare the combination of oral midazolam and ketamine (omk) with oral midazolam alone (om) as procedural sedatives among children undergoing computed tomography (ct) imaging. methods: the study population was comprised of six-m...

coronary-cameral fistulas (ccfs) constitute a rare anomaly that can be incidentally detected during angiography. ccfs are solitary, large or small assemblies that originate from coronary arteries and enter one of the cardiac chambers. we describe a 29-year-old woman, who referred to our clinic with the chief complaints of palpitation, atypical chest pain, and dyspnea on exertion (functional cla...

the aim of the current study was to determine the pattern, presentation and management of foreign body aspiration in our  population.  this prospective study comprised 55 patients with foreign body aspiration admitted to our department from january 2009 to december 2011. all patients underwent rigid bronchoscopy under local or general anesthesia. the patients’ demographic information along with...

lung contusion is an entity involving injury to the alveolar capillaries, without any tear or cut in the lung tissue. this results in accumulation of blood and other fluids within the lung tissue. the excess fluid interferes with gas exchange leading to hypoxia. the pathophysiology of lung contusion includes ventilation/perfusion mismatching, increased intrapulmonary shunting, increased lung wa...

background and aims. the imaging techniques commonly used for foreign body detection include plain radiography, xeroradiography, computed tomography (ct) scans, magnetic resonance imaging (mri) and ultrasonography. the aim of the present study was to compare cone-beam computed tomography (cbct) with conventional ct scan in determination of the exact location of a foreign body in the maxillofaci...

OBJECTIVE Our aim in this study was to determine the relationship between chest circumference and the radiation doses received by breast tissues during Dual-Source Computed Tomography (DSCT) cardiac scans. MATERIALS AND METHODS Routine cardiac DSCT examinations with similar exposure lengths were applied to 30 female patients. The scanogram image, multi-slice helical scan x-ray tube voltage an...
