OBJECTIVE To assess the effect of chest circumference-adapted scanning protocol on radiation exposure and image quality in patients undergoing prospective electrocardiogram (ECG)-triggered coronary CT angiography (CCTA). MATERIALS AND METHODS One hundred-eighty-five consecutive patients, who had undergone prospective ECG triggering CCTA with a 128-slice CT, were included in the present study....

PURPOSE To assess the advantages of iterative reconstruction for quantitative computed tomography (CT) analysis of pulmonary emphysema. MATERIALS AND METHODS Twenty-two patients with pulmonary emphysema underwent chest CT imaging using identical scanners with three different tube currents: 240, 120, and 60 mA. Scan data were converted to CT images using Adaptive Iterative Dose Reduction using...

Background: Chest CT is a commonly used examination for the diagnosis of lung diseases, but a breast within the scanned field is nearly never the organ of interest.Objective: The purpose of this study is to compare the female breast and lung doses using split and standard protocols in chest CT scanning.Materials and Methods: The sliced chest and breast female phantoms were used. CT exams were p...

Amoebiasis is a worldwide parasitic infection although it is more prevalent in the subtropical and tropical countries. Extraintestinal amoebic infections currently have been reported in increased numbers of male homosexuals and immunocompromised patients. Here, we present an interesting case of a 27-year-old homosexual man with pleural empyema secondary to rupture of amoebic liver abscess. Usin...

Figure 1: Postoperative lateral chest X-ray showing the excellent alignment following short fixation, a chest tube to drain a pleural effusion, the cement leakage (arrow) and the vertebral reinforcement material (asterisk). The mechanism of the embolism was probably a vascular entry of cement during high pressure inflation to get the compressed vertebral separated. Figure 2: CT image: we can ob...

Intercostal drainage tubes (ie, chest tubes) are inserted to drain the pleural cavity of air, blood, pus, or lymph. The water-seal container connected to the chest tube allows one-way movement of air and liquid from the pleural cavity. The container should not be changed unless it is full, and the chest tube should not be clamped unnecessarily. After a chest tube is inserted, a nurse trained in...

STUDY OBJECTIVES To evaluate the incidence and clinical significance of delayed pneumothorax, and to analyze the influence of multiple variables on the rate of delayed pneumothorax associated with transthoracic needle biopsy (TTNB) of the lung. STUDY DESIGN Prospective study. SETTING Tertiary care university hospital. STUDY SUBJECTS Adult patients underwent TTNB from June 2001 to June 200...

Tuberculous empyema (TE) is an uncommon form of pleural tuberculous (TB). Although the incidence of TE has significantly decreased, it still threatens public health. Patients with TE experience a protracted illness and significant morbidity and mortality risk. Male sex is a significant risk factor for TE. Herein, we report an adult case of TE admitted to a tertiary care hospital of Iran with cl...

PURPOSE Prolonged air or fluid chest tube drainage may delay chest tube removal in thoracic surgery patients otherwise ready for discharge. We reviewed 20 months of experience at our institution with postoperative, outpatient chest tube management using a new portable chest tube device. DESCRIPTION From May 2003 to December 2004, 457 major thoracic procedures were performed at our institution...

OBJECTIVE To evaluate the diagnostic performance of Ultra-Low-Dose Chest CT (ULD CT) for the detection of any asbestos-related lesions (primary endpoint) and specific asbestos-related abnormalities, i.e. non-calcified and calcified pleural plaques, diffuse pleural thickening, asbestosis and significant lung nodules (secondary endpoints). MATERIAL AND METHODS 55 male patients (55.7±8.1 years o...
