[Radiological diagnostics in bone metastases]

GŐDÉNY Mária, BODOKY György

[Imaging plays a crucial role in defining bone metastases, and thus, therapy planning. We are responsible for accurate data collection, pre-treatment evaluation, evaluation of therapy response and post-treatment evaluation. Precision highly depends on the expertise and experience of the evaluating radiologist, and therefore, being familiar with the latest literature is essential. The bone status can be detected well by bone scan, analysed by conventional X-ray examination and by the cross... tovább »

[Rheumatoid arthritis: significance and methodology of cervical spine X-rays in everyday practice]

NÉMETH Ildikó, BUDAY Ilona, MOLNÁR Éva, NYITRAI Márta, SAÁRY Krisztina, TARKOVÁCS Andrea, VARSÁNYI Nóra, FARBAKY Zsófia

[Cervical spine joint destruction in rheumatoid arthritis may lead to progressive vertebral instability. It is a severe risk factor for cord compression, which may even lead to sudden death. Many patients with atlantoaxial subluxation may have no symptoms referable to the neck. True degree of subluxation may occur during anaesthesia when the neck muscles are relaxed and protective spasm is absent. The cervical deformities can be visualised on conventional, transoral and functional lateral view... tovább »

[Role of radiofrequency ablation in the treatment of malignant liver tumors - Possibilities and limitations]

BÁNSÁGHI Zoltán

[Radiofrequency tumour therapy is a minimally invasive procedure. It has been used in several specialities independently of the type and location of the tumour, and has shown its worth. In primary hepatic malignancies, radiofrequency ablation (RFA) is a curative procedure. Recent publications reveal that hepatocellular carcinomas which were of cirrhotic origin and not larger than 5 cm have shown similar responses to both RFA and surgery. In cases of metastatic hepatic tumours, RFA showed... tovább »

[Use of plain and intravenous contrast material multidetector CT examinations in acute abdomen]

TÓTH László, TÓTH Géza, TURUPOLI Emőke, LOMBAY Béla, PAVLIKOVICS Gábor

[Through most of Europe, multidetector computed tomography is used as the first-line modalitiy for examining the acute abdomen. Acute abdominal pain, symptoms referring to abnormal bowel movements, gastrointestinal bleeding, worsening general state, and other typical clinical signs require quick and precise diagnosis since these conditions are frequently life-threatening. The sensitivity and specificity of CT examinations have significantly improved due to the development of the machinary.... tovább »

[Forces exerted on the plaques during in vitro measurements by various carotid stent delivery systems and embolic protection devices]

SZIKRA Péter, VÖRÖS Erika, SZTRIHA László, SZÓLICS Alex, PALKÓ András

[PURPOSE - During the endovascular treatment of internal carotid artery stenosis, one of the most important aspects is reducing of embolic complications. Degree of embolization may be influenced by the force exerted by stent delivery systems and embolic protection devices. We assessed the force emersion produced by various devices on vessel walls and plaques. MATERIAL AND METHOD - Six different commercially available devices were investigated. The force load on vessel wall was measured in a... tovább »

[The bubble-sign of spontaneous pneumoperitoneum]

SZÁNTÓ Dezső

[INTRODUCTION - Pneumoperitoneum is a reliable indicator of serious underlying damage. There are four etiologic categories of extraluminal-intraperitoneal gas collections: spontaneous, iatrogenic, traumatic and criminal perforations. The erect posteroanterior chest radiograph is the most sensitive plain film projection for detecting pneumoperitoneum and it may show 0.5-1 ml free abdominal gas when meticulous radiographic techniques (lateral, oblique, air-gap, lordotic, inspiratory and... tovább »
