PURPOSE To investigate whether the multislice CT scanning protocols of head, chest and abdomen are adjusted according to patient's age in paediatric patients. MATERIALS AND METHODS Multislice CT examination records of paediatric patients undergoing head, chest and abdomen scans from three public hospitals during a one-year period were retrospectively reviewed. Patients were categorised into t...

A 75-year-old woman underwent transthoracic CT-guided cutting-needle biopsy of a 5 5-cm mass of the superior segment of the left lower lobe and had an episode of recent hemoptysis. She had been ill for 3 months with dyspnea, cough, and intermittent sputum production. Chest radiographs revealed a persistent left lower lobe alveolar opacification believed to be pneumonia; however, the patient had...

Digital tomosynthesis is a radiographic technique that can produce an arbitrary number of section images of a patient from a single pass of the X-ray tube. It utilizes a conventional X-ray tube, a flat-panel detector, a computer-controlled tube mover, and special reconstruction algorithms to produce section images. While it does not have the depth resolution of computed tomography (CT), tomosyn...

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

Malpositioning is one of the most common complications of chest tube insertion and is associated with increased morbidity and mortality. We present two cases of patients with chronic obstructive pulmonary disorder (COPD) in whom malpositioned chest tubes penetrated through the anterior mediastinum to the contralateral pleural cavity, and were later removed without complications. Both patients h...

AIM To evaluate the association of quantitative computed tomography (CT) measures of emphysema with the occurrence of pneumothorax after CT-guided needle lung biopsy (NLB) accounting for other risk factors. MATERIALS AND METHODS One hundred and sixty-three CT-guided NLBs performed between 2008 and 2013 with available complete chest CT within 30 days were reviewed for the occurrence of post-pr...

BACKGROUND Supine anteroposterior (AP) chest radiography is an insensitive test for detecting posttraumatic pneumothoraces (PTXs). Computed tomography (CT) often identifies occult pneumothoraces (OPTXs) not diagnosed by chest radiography. All previous literature describes the epidemiology of OPTX in patients with blunt polytrauma. Our goal was to identify the frequency of OPTXs in patients with...

BACKGROUND Supine anteroposterior (AP) chest radiography may not detect the presence of a small or medium pneumothorax (PTX) in trauma patients. OBJECTIVES To compare the sensitivity and specificity of bedside ultrasound (US) in the emergency department (ED) with supine portable AP chest radiography for the detection of PTX in trauma patients, and to determine whether US can grade the size of...

Evaluation for pneumothorax is an important indication for obtaining chest radiographs in patients who have had trauma, recent cardiothoracic surgery or are on ventilator support. By definition, a persistent pneumothorax constitutes ongoing bubbling of air from an in situ chest drain, 48 h after its insertion. Persistent pneumothorax remains a diagnostic dilemma and identification of potentiall...
