[Role of imaging in the managment of colorectal cancer]

JEDERÁN Éva, GŐDÉNY Mária

[Colorectal cancer is the third most common cancer worldwide and the second most common cause of cancer death in Hungary. Diagnosis requires the examination of the entire large bowel by means of radiological and/or endoscopic techniques. Colorectal cancer primarily develops from adenomatous polyp over a period of 10-15 years. Tumour staging is crucial for the prognosis and for the planning of the most suitable anticancer therapy. The role of imaging in colorectal cancer is increasing with the... tovább »

[Colorectal cancer screening: Lessons from the American experience]

BAFFY György, TÁRNOKI Dávid László, TÁRNOKI Ádám Domonkos, BAFFY Noémi

[Colorectal cancer is one of the most common malignancies of our times. The disease takes many years to develop and is typically preceded by polyp formation, which allows timely screening and diagnosis. A number of tests and procedures have been developed to screen for colorectal cancer and its premalignant conditions. However, apparent heterogeneity of the disease, redundancy of the available screening modalities, as well as costs and potential pitfalls of these preventive measures require... tovább »

[Ways of imaging the expression of vascular endothelial growth factor and its receptor]

KOROM Csaba, KARLINGER Kinga

[The vascular endothelial growth factor (VEGF) and its receptors (VEGFR) signal-transduction pathway play a key role in the regulation of angiogenesis. It was originally isolated as a selective mitogen for endothelial cells and as a powerful vascular permeability increasing factor. The vascular imaging techniques make the quantification and localization of blood vessels possible. They have been used to assess blood flow, oxygenation, and vascular permeability. Also, they can be used to examine... tovább »

[Portal embolisation prior to liver resection]

MÓZES Péter, MÉSZÁROS György, TÓTH Judit, SÁPY Péter

[INTRODUCTION - By partial embolisation of the vena portae the number of the patients suitable for radical liverresection can be enhanced, the safety of the operation can be increased, the subsequent results improved. The method is based on the experience that when blocking the circulation of the portal system in special segments of the liver, the other part of the organ tries to substitute the functional deficiency by hypertrophy. Vena portae embolisation is justified in cases when the liver... tovább »

[Interventional neuroradiological treatment of a symptomatic basilar artery stenosis in the background of recurrent brainstem transient ischemic attack]

LOVÁSZ Rita, NÉMETH Csilla, LÁZÁR István, VALIKOVICS Attila

[INTRODUCTION - Symptomatic stenosis of the basilar artery carries high risk of brainstem stroke. In case of acute thrombotic occlusion of the basilar artery the mortality is over 70%. Besides best medical treatment, angioplasty was employed for 30 years previously, but the results were only acceptable after the advent of flexible intracranial stents. We report our case to call attention to the availibility of this interventional neuroradiological procedure. CASE REPORT - A 64 years old male... tovább »

[Omental infarction diagnosed with ultrasonography]

VÁRKONYI Ildikó, VÖRÖS Péter, SZÉKELY Eszter

[INTRODUCTION - Omental infarction is a rare entity, mimicking symptoms of acute appendicitis. Although omental infarction has typical morphology, both on sonography and CT, it is rarely diagnosed preoperatively. CASE REPORT - A 4-years-old girl presenting with right lower quadrant abdominal pain underwent abdominal sonography, which revealed normal appendix and a superficial hyperechoic solid mass at the site of the pain. The patient underwent laparotomy which confirmed the presumed diagnosis... tovább »

[Experimental e-Learning course in the further training of Hungarian radiographers]

VANDULEK Csaba, TÓTH Lilla, DONKÓ Tamás, PAVLIKOVICS Gábor, BOGNER Péter, CSONTOS Éva, REPA Imre

[The growth in digital media technology within the past decade has strengthened e-Learning’s position in education. Traditional teaching methods are changing: from teacher to moderator and passive learner to active learner. A pilot e-Learning course in MR angiography (MRA) has been undertaken with Hungarian radiographer participants. The e-Learning course consisted of three phases covering basic MRA physics and technical aspects, advanced MRA techniques and concluding with an assessment work.... tovább »
