Abstract
In recent years continuous advancements in software and hardware technology of modern MRI systems have contributed to substantial progress in the field of pancreatic tumor imaging. Despite technical advances in abdominal MRI, multislice CT still remains the preferential diagnostic tool for pancreatic lesions. In the majority of cases the essential clinical questions can thereby be answered with a high degree of accuracy. However, in dilemma cases state-of-the-art MR imaging can provide relevant information for the diagnosis allowing an optimal therapeutic concept. This report gives an overview on possible applications for MRI in the diagnostic evaluation of malignant pancreatic tumors.

Abstract
1530 Background: BRCA1 or BRCA2 mutation carriers are at an increased lifetime risk to develop breast and ovarian cancer. In a substantial number of families with affected members the known susceptibility genes cannot be identified. According to the recommendations of the German Consortium for Hereditary Breast and Ovarian Cancer, women with a hereditary predisposition for breast cancer should participate at an intensified surveillance program (ISP) including genetic counseling, risk estimation, BSE, CBE, BreastUS, MX, and MRI. Nonadherence might be influenced by cancer worryness, anxiety, health beliefs, and a lack of information about screening benefits.The aim of this investigation was to evaluate the impact of an indivualized Breast Cancer Awareness Training to improve the participation and adherence towards an ISP. Methods: Since 2005, an at-risk sample of 46 non-participating women (mean age 29 y; range 19–43 y) got an intensive breast cancer awareness training, including structured BSE, specific information about regular follow-up, screening advice, and radiological diagnostic procedures. To establish invidualized counseling and training particular needs (e.g., reasons for non-adherence, health beliefs and behaviours), risk perception, anxiety, and sociodemographic factors were evaluated by interviews and self-report questionnaires. The control group consisted of 38 participants of the ISP. Results: Breast cancer worry, anxiety, and lack of information about the benefits of screening programs were the main reasons for non-adherence. Within 3 months after the base counseling participation rates in MX (>30J), BUS, MRI, and CBE reached 98%. The numbers remain consistent in a 2-year follow up. 80% of participants practice BSE monthly, and 46% reported changes in lifestyle regarding nutrition, obesity, and health beliefs. Conclusions: Our approach emphasizes importance of self confidence and awareness for participation at the ISP for women at high breast cancer risk. Individualized counseling, BSE, re-evaluation, and reinforcement sessions are correlated with changes in health beliefs and behaviours for enhancing participation and adherence in women with a family history of breast cancer. No significant financial relationships to disclose.

Abstract #2046
Background: Components of the plasminogen activator system play a key role in tumor invasion and metastasis. Tumor tissue levels of urokinase-type plasminogen activator (uPA) and its inhibitor PAI-1 showed a strong prognostic impact in node-negative and node-positive primary BC. uPA/PAI-1 were the first novel prognostic factors in primary BC reaching the highest level of evidence for their clinical utility and they have recently been recommended by ASCO for clinical decision making.
 Material and Methods: For the first time, correlations between uPA and PAI-1 concentrations in 73 primary tumor tissues and corresponding axillary lymphnodes (ALN) in node-negative (pN0) and node-positive (pN+) BC (1991-98) and their prognostic impact on disease-free (DFS) and overall survival (OS) were evaluated.
 Results: Median follow-up was 56 months. Overall, PAI-I (p=0,014) and uPA concentrations (p<0,001) were significantly higher in tumour tissue than in the corresponding ALN. There was no significant difference of PAI-1 in primary tumor tissue between pN0 and pN+ disease. In involved ALN (pN+), concentrations of PAI-1 but not of uPA, were significantly higher than in pN0 (p<0.001). Moreover, patients with higher PAI-1 concentrations in the corresponding ALN than in their primary tumor had a significantly shorter DFS (p<0,001) and OS (p=0.005).
 Discussion: Our clinical findings support the basic research data implicating uPA and PAI-1 as key proteolytic factors in metastasis-asociated processes such as adhesion, angiogenesis, invasion, proliferation and migration. For the first time, we are able to demonstrate that particularly PAI-1 seems to be involved in tumor metastasis in primary breast cancer with its concentrations being higher in involved ALN than in the primary tumor. Besides uPA/PAI-1 being validated and clinically useful prognostic factors, interference with the uPA/PAI-1 system thus promises to be an interesting therapeutic concept in BC.

Abstract
PURPOSE The usefulness of whole-body MRI (WB-MRI) for the detection of skeletal lesions in patients with Langerhans cell histiocytosis should be documented on the basis of case presentations. MATERIALS AND METHODS In six patients with histologically proven Langerhans cell histiocytosis, 14 WB-MRI examinations were performed to evaluate the skeletal system within disease staging (6 primary, 8 follow-up examinations). The examinations were performed on a 1.5 Tesla, 32-channel whole-body scanner. The examination protocol consisted of T 1-weighted and STIR sequences in coronal and sagittal orientation. For comparison, radiographs of the initial skeletal lesions and those that were additionally detected on WB-MRI were available. RESULTS In 4 patients no additional skeletal lesions were found on WB-MRI besides the initial lesion leading to the diagnosis of unifocal single system disease. In 2 patients WB-MRI was able to identify additional skeletal lesions. In a 5 S year-old boy with the primary lesion located in the cervical spine, a second lesion was detected in the lumbar spine on the initial scan and in the skull and proximal femur during follow-up examination. In a 12 year-old girl with a primary lesion of the thoracic spine, WB-MRI diagnosed additional lesions in the pelvic bone and the tibia. In both patients the diagnosis of multifocal skeletal involvement led to chemotherapy. During follow-up examination, the healing response under therapy could be demonstrated. Comparison with conventional imaging showed that especially lesions located in the spine or the pelvis were not detectable on radiographs even when knowing the MR results. CONCLUSION The extent of skeletal involvement in Langerhans cell histiocytosis has crucial impact on therapy and prognosis. Whole-body MRI has been reported to be an established method for the evaluation of disseminated skeletal disease with distinct advantages over conventional radiography and bone scintigraphy. Our results suggest that WB-MRI should also be the imaging modality of choice for the assessment of skeletal involvement in children with Langerhans cell histiocytosis.

Abstract
OBJECTIVES To clarify challenges and research topics for informatics in health and to describe new approaches for interdisciplinary collaboration and education. METHODS Research challenges and possible solutions were elaborated by scientists of two universities using an interdisciplinary approach, in a series of meetings over several months. RESULTS AND CONCLUSION In order to translate scientific results from bench to bedside and further into an evidence-based and efficient health system, intensive collaboration is needed between experts from medicine, biology, informatics, engineering, public health, as well as social and economic sciences. Research challenges can be attributed to four areas: bioinformatics and systems biology, biomedical engineering and informatics, health informatics and individual healthcare, and public health informatics. In order to bridge existing gaps between different disciplines and cultures, we suggest focusing on interdisciplinary education, taking an integrative approach and starting interdisciplinary practice at early stages of education.

Abstract
PURPOSE The present work describes the potential of iron oxides for the detection of macrophages in synovitis in experimental, antigen-induced arthritis. METHODS The pivotal role of macrophages in rheumatoid arthritis (RA) in humans and in antigen-induced arthritis (AIA) in animal models is discussed. The latter appear to be very similar in many aspects to the human RA. We show the potential for iron oxide-enhanced magnetic resonance imaging (MRI) to determine the macrophage content in the arthritic synovial membranes. The results of our own research, as well as those of other research groups, are presented and discussed. RESULTS MRI after the intravenous (i.v.) administration of iron oxides enables the depiction of macrophage content in arthritic synovial membranes in AIA through the effects of the intracellular compartmentalisation of iron oxide particles. These effects can be demonstrated in 24-h delayed images after i.v. contrast application, on T2-weighted spin-echo or turbo-spin-echo sequences, and especially on T2*-weighted gradient-echo sequences. The signal effects are not only apparent in high field strength (4.7 Tesla) but also on 1.5 Tesla clinical scanners. CONCLUSIONS AND PERSPECTIVES The use of iron oxides enables the determination of the macrophage content in synovitis in animals with AIA. This parameter represents a potential marker to determine disease activity, and possibly represents a marker to evaluate the effectiveness of specific therapies in human RA. Current knowledge of iron oxide-enhanced MRI is limited to animal models. The clinical evaluation of this new method in patients with RA has not yet been performed. However, based on the considerations presented here, significant progress in the diagnostic work-up of RA can be expected.

Abstract
Retention of surgical sponges is rare. They cause either an aseptic reaction without significant symptoms or an exudative reaction which results in early but non-specific symptoms. Even if there are no studies which compare the diagnostic accuracy of the different imaging modalities, CT seems to be the most promising tool to diagnose foreign bodies. However, apart from radio-paque markers there are no specific signs for the existence of surgical sponges in CT. Therefore, an experienced radiologist is needed to differentiate foreign bodies from morphologically quite similar differential diagnoses such as abscess and haematoma.

Abstract
The aim of this prospective trial was to evaluate sensitivity and specificity of bright lumen magnetic resonance colonography (MRC) in comparison with conventional colonoscopy (CC). A total of 120 consecutive patients with clinical indications for CC were prospectively examined using MRC (1.5 Tesla) which was then followed by CC. Prior to MRC, the cleansed colon was filled with a gadolinium-water solution. A 3D GRE sequence was performed with the patient in the prone and supine position, each acquired during one breathhold period. After division of the colon into five segments, interactive data analysis was carried out using three-dimensional post-processing, including a virtual intraluminal view. The results of CC served as a reference standard. In all patients MRC was performed successfully and no complications occurred. Image quality was diagnostic in 92% (574/620 colonic segments). On a per-patient basis, the results of MRC were as follows: sensitivity 84% (95% CI 71.7-92.3%), specificity 97% (95% CI 89.0-99.6%). Five flat adenomas and 6/16 small polyps (< or =5 mm) were not identified by MRC. MRC offers high sensitivity and excellent specificity rates in patients with clinical indications for CC. Improved MRC techniques are needed to detect small polyps and flat adenomas.

Abstract
Squamous cell carcinomas and adenocarcinomas account for the majority of cases of esophageal cancer. Esophageal cancer often is diagnosed in advanced stages as clinical symptoms are lacking in early stages. The major aims of imaging in esophageal cancer are to determine local tumor extension (T and N staging), to rule out systemic disease (M staging), and to assess response to neoadjuvant therapy (response evaluation). CT is still inferior to endoscopic ultrasound in differentiating T stages and detecting regional lymph node metastases. However, it plays a central role in determining infiltration into adjacent organs (T4 stage) and in ruling out distant metastases. Multislice-CT (MSCT) offers the possibility of reconstructions, which often help to assess the relationship between tumor and anatomic landmarks like the tracheobronchial tree or the diaphragm. First results of CT volumetry for response evaluation are promising; however, PET and PET/CT with the glucose analogue FDG are the standard methods to evaluate response to neoadjuvant therapy.
