The aim of the study was to investigate the potential role of chest tomosynthesis (CTS) at a tertiary referral centre by exploring to what extent CTS could substitute chest radiography (CXR) and computed tomography (CT). The study comprised 1433 CXR, 523 CT and 216 CTS examinations performed 5 years after the introduction of CTS. For each examination, it was decided if CTS would have been appro...

OBJECTIVE To investigate the feasibility of determination of right ventricular outflow tract (RVOT) high septal pacing site visualized by real-time three-dimensional echocardiography (RT3DE). METHODS The forty subjects with RVOT pacing were analysed. RT3DE determination of RVOT high septal pacing sites was compared with chest X-ray (CXR). RESULTS RVOT septal pacing sites could be obtained i...

We applaud the British Thoracic Society (BTS) for its efforts to improve patient care through scientific evidence. We thus recognise the recent guidelines on pleural procedures and thoracic ultrasound (TUS) as an important attempt to develop a rational approach to chest sonography. 1 However, we are concerned that the BTS has reached conclusions based on a less complete review of TUS. The guide...

با وجود روش های دقیق تر تصویربرداری از قلب، هنوز گرافی ساده قفسه صدری (chest-x-ray=cxr) اولین روش تصویربرداری در افراد مشکوک به بیماری قبلی می باشد. مهم ترین کاربرد cxr در بیماران قلبی تخمین اندازه قلب است. دو روش اصلی تخمین اندازه قلب در cxr اندازه گیری قطر عرضی قلب (transverse diameter=td) و محاسبه نسبت عرض قلب به عرض قفسه سینه (cardiothoracic ratio=ctr) می باشد. اکوکاردیوگرافی روش استاندارد ...

The transition from conventional screen-film radiography (SFR) to computed radiography (CR) or digital radiography (DR) can involve an increase in patient radiation doses due to the wide dynamic range of the digital imaging systems, which allows overexposure with no adverse effect on image quality. The current study intends to measure and compare the radiation dose to adult patients during (i) ...

BACKGROUND The role of routine chest radiography (CXR) after percutaneous dilatational tracheostomy (PDT) has been questioned. METHODS We performed a prospective observational study, on a mixed medical/surgical critical care unit in a university teaching hospital. We studied all patients undergoing PDT as part of their critical care management from November 1, 2003 until July 31, 2007. All PD...

BACKGROUND It is the routine of our hospital that all patients undergoing any kind of surgery in any specialty are subjected to routine pre-op chest x-ray (CXR). However there is increasing evidence that this practice does not have much influence on patient management and thus could be limited to a very small number of patients in whom it is justified. We conducted this study to know the signif...

Chest x-rays (CXR) still play an important role in detection of airway disease. Airway stenosis is a key sign of disease such as paediatric tuberculosis but is challenging to measure in CXR because the airway has relatively low contrast compared to overlying structures. In this study a novel approach to identify airways in CXRs is introduced, using a 3D statistical shape model to guide the segm...
