OBJECTIVE We wanted to determine minimal tube current (mAs) required for consistently good image quality on conventional 10-mm collimation chest CT and effect of tube current reduction on detection of mediastinal and lung abnormalities. Tube current reduction is desirable to reduce patient radiation dose. SUBJECTS AND METHODS Prospectively, 30 consecutive patients (mean weight, 68 kg; range, ...

INTRODUCTION We aimed to determine a potentially optimal body size index for adjusting the tube current in retrospective ECG-triggered helical 256-slice CT coronary angiography (CTCA) for individualized radiation dose control. METHODS Consecutive patients (n=102) with suspected coronary artery disease underwent retrospective ECG-triggered CTCA with a 256-slice CT scanner. Body mass index (BMI...

Automatic tube current modulation (ATCM) systems are available for all CT manufacturers and are used for the majority of patients. Understanding how the systems work and their influence on patient dose and image quality is important for CT users, in order to gain the most effective use of the systems. In the present study, a new phantom was used for evaluating dose distribution and image qualit...

1 of 2 DESCRIPTION A 56-year-old male smoker sustained non-penetrating leftsided chest trauma, following a 2-m fall onto a fl at-topped wooden post. He was in severe pain and respiratory distress in the Emergency Department, with a dramatic degree of fl ail and marked subcutaneous emphysema (see video 1 ). A left side tube thoracostomy was inserted urgently with marked improvement in respirator...

background: chest tube removal is a painful procedure. the goal of this study was to evaluate the effect of cold application incombination with indomethacin suppository on chest tube removal pain in patients undergoing open heart surgery. materials and methods: this single-blind, double-group clinical trial was performed on 66 patients aged 18-68 years with thechest tube in pleural space. the i...

results a total of 43 (12 males and 31 females, with mean age of 41.90 ± 8.64 years) patients underwent minithoracotomy for open lung biopsy. minithoracotomy mortality rate was 0% compared to the 0 - 5.2% reported for thoracoscopy. the mean hospital stay for minithoracotomy was 2.3 ± 0.97 days compared to 4.9 ± 1.53 days reported for thoracoscopy (p < 0.05). the complication rate was 0.05% and ...

BACKGROUND Multiloculated pleural effusion is a life-threatening condition that needs early recognition. Drainage by chest tube might be difficult which necessitates a surgical intervention. While x-ray typically does not show loculations, CT scan might not also identify the loculations. Ultrasound has a high sensitivity in detecting pleural diseases including multiloculated pleural effusion. ...
