BACKGROUND The clinical value of computed tomographic (CT) scanning of the chest in the initial assessment of sarcoidosis was investigated. METHODS One hundred consecutive patients referred to the sarcoidosis outpatient services of the Mount Sinai Medical Center, New York from 1990 to 1992 with a presumptive diagnosis of sarcoidosis were studied. The diagnosis was subsequently confirmed in al...

introduction: application of chest radiography for all multiple trauma patients is associated with a significant increase in total costs, exposure to radiation, and overcrowding of the emergency department. ultrasound has been introduced as an alternative diagnostic tool in this regard. the aim of the present study is to compare the diagnostic accuracy of chest ultrasonography and radiography i...

BACKGROUND Unnecessary diagnostic imaging leads to higher costs, longer emergency department stays, and increased patient exposure to ionizing radiation. We sought to prospectively derive and validate two decision instruments (DIs) for selective chest computed tomography (CT) in adult blunt trauma patients. METHODS AND FINDINGS From September 2011 to May 2014, we prospectively enrolled blunt ...

This study aimed to investigate whether pulmonary shunt grade on transthoracic contrast echocardiography (TTCE) predicts the size of pulmonary arteriovenous malformations (PAVMs) on chest computed tomography (CT) and subsequent feasibility for transcatheter embolotherapy. We prospectively included 772 persons with possible or definite hereditary haemorrhagic telangiectasia, who underwent both T...

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...

Acute chest pain (ACP) is one of the most common presenting symptoms at the emergency department. The differential diagnosis is vast. To exclude life-threatening causes, radiologists encounter an increasing amount of thoracic computed tomography (CT) examinations including CT angiography of the heart and great vessels. The dual- and triple-rule CT examinations are currently implemented in clini...

A 37 - year- old man came to the hospital with a history of penetrating thoracoabdominal trauma due to gunshot wound in 10 days before. He underwent laparatomy and hepatorrhaphy in that time and right sided chest tube was inserted. Chest CT scan revealed metallic foreign body in lung tissue due to bullet burst. Right thoracotomy was performed and metallic foreign body extracted from lung tissue
