Computer-aided reading (CAR) of medical images is becoming increasingly common, but few studies exist for CAR in tuberculosis (TB). We designed a prospective study evaluating CAR for chest radiography (CXR) as a triage tool before Xpert MTB/RIF (Xpert).Consecutively enrolled adults in Dhaka, Bangladesh, with TB symptoms received CXR and Xpert. Each image was scored by CAR and graded by a radiol...
The aim of this study was to compare clinical staging and magnetic resonance imaging (MRI) staging for oral cancer, and to assess inter-observer agreement between oral and medical radiologists. A total of 10 patients diagnosed with oral cancer were assessed before treatment. A head and neck surgeon performed clinical TNM staging. Two medical radiologists and two oral radiologists performed a ne...
As part of the American Cancer Society-VA Cooperative Pilot Study for the evaluation of radiologie and sputum cytologie screening in the early detection of lung cancer, it was possible to obtain some estimate of the variability in the interpretation of chest X-rays by radiologists. With respect to interindividual variability, the positive readings of one radiologist will be called positive by a...
BACKGROUND Community-acquired pneumonia (CAP) is an important cause of acute respiratory disease in ambulatory care settings. The objective of this study was to assess the accuracy of medical history and physical examination in diagnosing CAP. METHODS Pediatric residents prospectively completed a questionnaire documenting patients' medical history and physical examination whenever a chest rad...
BACKGROUND The use of point-of-care ultrasonography (POC US) in paediatrics is increasing. This study investigated the diagnostic accuracy of POC US in children accessing the emergency department (ED) when performed by paediatricians under the remote guidance of radiologists (TELE POC). METHODS Children aged 0 to 18 years accessing the ED of a third level research hospital with eight possible...
BACKGROUND The purpose of this study was to investigate the diagnostic value of 3.0-T (1)H magnetic resonance spectroscopy ((1)H MRS) in primary malignant hepatic tumors and to compare the effects of (1)H MRS on the diagnostic accuracy of liver-occupying lesions between junior and experienced radiologists. METHODS This study included 50 healthy volunteers and 40 consecutive patients (50 lesio...
We employ mixed reality as a collaborative tool for intra-operative planning of extended liver resections. The most important advantage of real time visualization of intrahepatic vascular structures using see-through glasses is the improved accuracy of the preparation of liver parenchyma. The impact of using augmented reality as an intra-operative navigation system should result in sparing sane...
