STUDY OBJECTIVES Despite the widespread use of lung scanning and angiography, pulmonary embolisms (PEs) remain undiagnosed in the majority of patients, suggesting the need for alternative diagnostic approaches. The present study investigates the clinical utility of transthoracic sonography (TS) for the diagnosis of PE and compares the data obtained with the(More)
Percutaneous transhepatic stenting of the main portal vein is a rare intervention. In the current patient, percutaneous angioplasty and stenting of a main portal vein stenosis due to lymphatic recurrence of gastric cancer ameliorated the progressing therapeutic restriction. The wall stent achieved portal venous patency that enabled ongoing chemotherapy. The(More)
Dilated cardiomyopathy (DCM) is accompanied by an impaired cardiac energy metabolism. The aim of this study was to investigate metabolic ratios in patients with DCM compared to controls by using spectroscopic two-dimensional chemical shift imaging (2D-CSI). Twenty volunteers and 15 patients with severe symptoms (left ventricular ejection fraction, LVEF<30%)(More)
The aim of this study was to investigate a new bone densitometric technology based on digital radiogrammetry (DXR) with respect to its ability to measure severity-dependent variations of bone mineralization in patients with rheumatoid arthritis. One hundred six randomly selected patients suffering from verified rheumatoid arthritis underwent digitally(More)
To evaluate the reproducibility of imaging and analysis for bone mineral density (BMD) determination using digital computer-assisted X-ray radiogrammetry (DXR; Pronosco X-posure, version V.2, Sectra Pronosco, Denmark); to verify potential factors that influence BMD extrapolation such as tube voltage, film-focus distance (FFD), film quality and brand (Kodak(More)
The double aorta is very rare. Only two cases are described in the literature. More frequent is a duplication artifact which is misinterpreted as being the image of a double aorta. This is caused by a refraction artifact which results from the difference in the velocity of sound between muscle tissue and fat tissue. Furthermore, a fat depot between parts of(More)
PURPOSE To find out the individual level of radiation exposure of the ocular lens and thyroid gland during DSA of arteries supplying the brain, considering the indication. MATERIAL AND METHOD The study was conducted on 72 patients during aortic arch and cerebral artery angiographies using thermoluminescent dosimetry. RESULTS During 20 aortic arch(More)
BACKGROUND AND OBJECTIVE Pulmonary embolism often extends to pleural surfaces, resulting in pleural-based parenchymal lesions. This study was carried out in order to evaluate the clinical value of transthoracic sonography (TS) for the diagnosis of pulmonary embolism. PATIENTS AND METHODS A prospective study was performed in 45 patients (27 men, 18 women;(More)
OBJECTIVE To evaluate the impact on cardiac magnetic resonance imaging (CMRI) with adenosine stress and delayed enhancement for indication and follow up after interventional recanalisation of chronic total coronary occlusions (CTOs). MATERIAL AND METHODS Twenty consecutive patients (15 males; 5 females; mean age 65 years) with CTO verified by cardiac(More)
PURPOSE How much can the radiation dose be reduced for hand radiography by using digital luminescence radiography (DLR)? METHODS AND MATERIALS A hand phantom (3M) with a cyst, two fractures and an "amputation" was digitally exposed in an anterior-posterior orientation using DLR (ADC-70, Agfa). The tube current time product (mAs) was reduced gradually(More)
