[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. The promising results suggest that e-learning may be a feasable method for the continuing professional development of Hungarian radiographers.]

[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 change in complex tumour therapy. With advances in ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI) techniques accuracy of imaging has improved. The accuracy of CT improved with the advent of the multislice technique (MDCT). Sensitivity and specificity of CT colonography (CTC) in colon polyps and cancer is over 90%, therefore it is one of the screening tools. Accuracy of the CTC is comparable to the optical colonoscopy, complements conventional colonoscopy well and it is an effective tool in the right hands. Endorectal US (ERUS) depicts the anatomic layers of the rectal wall with high degree of accuracy, therefore it is the best method for the evaluation of the lower tumour stage. High resolution MRI is the most suitable technique for predicting rectal tumor stage, therefore it has been established as the standard for preoperative assessment of rectal cancer.]

[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 careful strategic planning. In the United States, recent advances in the campaign for colorectal cancer screening provide important lessons that may guide similar initiatives in Hungary.]

[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 the molecular and cellular difference in the vascular wall. To evaluate tumour vascularity, a multimodality approach is expanding. VEGF as the primary mediator for vascular-permeability is indirectly measurable with DCE-MRI (dynamic contrastenhanced MRI). MRI investigation can determine the ratio of deoxyhemoglobin/oxyhemoglobin in order to localize the hypoxic regions in vivo (BOLD [blood oxygen-level dependent] sequence and OMRI [Overhauser MRI]). In molecular MRI (mMRI), contrast agent-mediated alteration of tissue relaxation times can allow for the detection and localization of molecular disease markers. To localize the expression of VEGFR with SPECT and PET, antibodies and VEGF isoforms can be marked with isotopes. VEGFR is an excellent candidate for targeted ultrasound imaging since it is almost exclusively expressed on activated endothelial cells. Optical imaging is a relatively cheap method suitable so far primarily for small animal studies.]

[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 substance remaining after the planned operation is critically small. PATIENTS AND METHODS - The authors carried out vena portae embolisation at Debrecen University Medical and Health Science Centre since October 2003 on six patients. Assessments were made studying the volume of the whole liver, the lobe affected by embolisation and that of the unaffected lobe, by CT-volumetry. The average age of the patients (four men and two women) was 63 years (51-67 years). The hepatic tumour was an extended metastasis localised to one lobe in five cases, and HCC in one of the patients. In each case we carried out closing the right lobe’s portal system. RESULTS - In five cases the left lobe showed increase following the portal embolisation of the right lobe intended to be removed. On the average four-six weeks passed between the two CT-examinations. The growth of the left lobe was an average of 42% (min. 11.8%, max. 75.6%). CONCLUSION - In selected patients the embolisation of the vena portae system of the tumorous liver-segments is a suitable method for enlargening the size of the liver substance remaining after an extensive resection.]

[The role of MR angiography in the examination of intracranial aneurysms: A comparative study]

P. Nagy Zoltán, BAJZIK Gábor , BOGNER Péter, BERÉNYI Ervin, SZÁSZ Krisztina, KOPA János, REPA Imre

[MR imaging has recently emerged for visual representation of blood vessel structures as well. With MR angiography (MRA), appropriate diagnosis can be established for a number of pathologies involving the arteries and veins. In this report, authors analyse the significance of MR and MRA examinations in the diagnostics of intracranial aneurysms of 87 cases, comparing these procedures with results obtained by digital subtraction angiography (DSA), which is regarded as the gold standard method. In 52 patients where surgical intervention was performed, intraoperative findings were used as control. MR - MR angiographic examination was very sensitive in detecting aneurysms larger than 3 mm (98%), the rate of depicting smaller aneurysms proved to be lower (56%), the overall sensitivity was 79%. MRA is an excellent non invasive diagnostic tool in the examination of intracranial aneurysms. The method can not replace catheter angiography completely but its application is justified and useful in many cases. Occasionally, aneurysms not seen on DSA can be depicted with MR angiography. ]

[The role of sleep in the relational memory processes ]

CSÁBI Eszter, ZÁMBÓ Ágnes, PROKECZ Lídia

[A growing body of evidence suggests that sleep plays an essential role in the consolidation of different memory systems, but less is known about the beneficial effect of sleep on relational memory processes and the recognition of emotional facial expressions, however, it is a fundamental cognitive skill in human everyday life. Thus, the study aims to investigate the effect of timing of learning and the role of sleep in relational memory processes. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. Our results suggest that the timing of learning and sleep plays an important role in the stabilizing process of memory representation to resist against forgetting.]

[The Comprehensive Aphasia Test in Hungarian]

ZAKARIÁS Lilla, RÓZSA Sándor, LUKÁCS Ágnes

[In this paper we present the Comprehensive Aphasia Test-Hungarian (CAT-H; Zakariás and Lukács, in preparation), an assessment tool newly adapted to Hungarian, currently under standardisation. The test is suitable for the assessment of an acquired language disorder, post-stroke aphasia. The aims of this paper are to present 1) the main characteristics of the test, its areas of application, and the process of the Hungarian adaptation and standardisation, 2) the first results from a sample of Hungarian people with aphasia and healthy controls. Ninety-nine people with aphasia, mostly with unilateral, left hemisphere stroke, and 19 neurologically intact control participants were administered the CAT-H. In addition, we developed a questionnaire assessing demographic and clinical information. The CAT-H consists of two parts, a Cognitive Screening Test and a Language Test. People with aphasia performed significantly worse than the control group in all language and almost all cognitive subtests of the CAT-H. Consistent with our expectations, the control group performed close to ceiling in all subtests, whereas people with aphasia exhibited great individual variability both in the language and the cognitive subtests. In addition, we found that age, time post-onset, and type of stroke were associated with cognitive and linguistic abilities measured by the CAT-H. Our results and our experiences clearly show that the CAT-H provides a comprehensive profile of a person’s impaired and intact language abilities and can be used to monitor language recovery as well as to screen for basic cognitive deficits in aphasia. We hope that the CAT-H will be a unique resource for rehabilitation professionals and aphasia researchers in aphasia assessment and diagnostics in Hungary. ]
