The hypereosinophilic syndrome (HES) is a rare disorder characterized by hypereosinophilia and infiltration of various organs with eosinophils. Eosinophilic cystitis (EC), mimicking bladder cancer clinically but also in ultrasound and in radiographic imaging, is one potential manifestation of the HES occurring in adults as well as in children. This case report describes the course of disease in a 57-year-old male presenting with severe gait disorders and symptoms of a low compliance bladder caused by a large retropubic tumor.

Methods: One hundred ninety-seven patients were divided into the subgroups "healthy", "benign disease" and "malignant disease". The interpretation of the images was performed at a slice thickness of 3 mm in the axial and coronal plane.
The growing complexity of radiologic examinations and interventional procedures requires frequent exchange of knowledge. Consequently a simple way to share and discuss patient images between radiology experts and with colleagues from other medical disciplines is needed. Aims of this work were the development and initial performance evaluation of a fast and user friendly, platform independent teleconsultation system for medical imaging.

Materials And Methods: Within a period of 11 days 115 patients were provided with a tablet computer while waiting for their magnetic resonance imaging examination. Every day the contamination of the surface of the tablet was determined before the first and after the final use.
Introduction: The aim of the study was to compare the detectability of neck vessels with contrast enhanced magnetic resonance angiography (MRA) in the setting of a whole-body MRA and multislice computed tomography angiography (CTA) for preoperative vascular mapping of head and neck.
Methods: In 20 patients MRA was performed prior to microvascular reconstruction of the mandible with osteomyocutaneous flaps. CTA of the neck served as the method of reference.
To analyze if an iPad-based patient briefing can serve as a digital alternative to conventional documentations prior to radiological examinations. One hundred one patients referred for routine MRI were randomized into two groups, who underwent iPad-based and classic written briefing in opposite order. For each briefing completion time, completeness and correctness were noted.

Materials And Methods: The study complies with the Declaration of Helsinki and was performed following approval by the ethic committee of the University of Erlangen-Nuremberg. Written informed consent was obtained from every patient.
To evaluate the feasibility of an iPad-based documented patient briefing for Magnetic Resonance Imaging (MRI) examinations. A standard briefing sheet and questionnaire for a MRI scan was converted from paper form into an iPad application. Twenty patients, who had been referred for an MRI scan, were briefed about the examination in paper form as well as via the iPad application before performing the MRI scan.

Methods: Fifty men with a history of negative transrectal ultrasound-guided biopsies underwent MRGB in either a 1.5-T (13/50) or 3.
We present the case of a 55-year-old patient with a history of chemotherapy and bone marrow transplantation because of acute myeloid leukaemia. An incidental 4 × 3 cm measuring renal mass was detected while performing a magnetic resonance imaging (MRI) for lumbago. The lesion was suspected to be either a renal cell carcinoma (RCC) or a leukemic infiltration.

Patients And Methods: Ninety-six men with suspected prostate cancer underwent MRI-guided prostate biopsies under real-time imaging control in supine position.
Results: Adenocarcinoma of the prostate was detected in 39 of 96 patients.
Purpose: To compare direct magnetic resonance galactography (dMRG) and conventional galactography (CGal).
Materials And Methods: Thirty women underwent CGal and dMRG. Duct localization and the depth of the assumed underlying pathology in CGal and dMRG were analyzed.
Objectives: Aim of the study was to evaluate if a whole-body magnetic resonance angiography (MRA) protocol meets the requirements to evaluate the donor and host site target vessels for planning of microvascular head and neck reconstructions.
Patients And Methods: In 20 patients, scheduled for reconstruction of the mandible with fibular free flaps, contrast-enhanced whole-body MRA was performed prior to surgery. 32-Channel 1.
Rationale And Objectives: Modern computed tomographic scanners and examination protocols often require high injection rates of iodinated contrast media (CM). The purpose of this study was to investigate the maximum injection pressures (MIPs) with different CM at different temperatures in the most common intravenous cannula (IVC) sizes.
Materials And Methods: Three IVC sizes, 22, 20, and 18 gauge, were evaluated.
Objectives: To adapt gamma-H2AX immunofluorescence microscopy to assessment of induction and repair of DNA double-strand breaks (DSBs) in peripheral blood lymphocytes in patients undergoing angiographic procedures.
Materials And Methods: The study was approved by the institutional ethics committee. After written informed patient consents were obtained, venous blood samples were taken from 19 patients (age 23-88 years) undergoing different angiographic procedures before, during, and after (10 minutes-24 hours) the examination.
Purpose: The aim of this study was to investigate whether there are typical findings in enteroclysis of patients suffering from food allergy (FA).
Materials And Methods: Findings of enteroclysis of 26 FA patients were correlated with results of endoscopic and histologic examinations. In two patients allergen provocation was performed during enteroclysis.
In the majority of patients with oesophageal carcinoma, curative treatment proves to be impossible when diagnosis was established; therefore, most of the patients are candidates for palliative chemotherapy. The aim of this phase II study was to evaluate the efficacy and safety of 5-fluorouracil/folinic acid (AIO regimen) plus irinotecan in patients with locally advanced or metastatic carcinoma of the oesophagus. The methods used a prospective phase II trial, start: November 2002; patients: n=25; chemotherapy: irinotecan (80 mg/m2) as a 1-h infusion and 5-fluorouracil (2000 mg/m2) with sodium folinic acid (500 mg/m2) as a 24-h infusion on days 1, 8, 15, 22, 29 and 36, repeated on day 57.

Materials And Methods: The study was approved by the institutional review board. Written informed consent was obtained from all patients.
Though being inferior to magnetic resonance imaging, computed tomography (CT) of the brain is the most frequently applied imaging modality in the diagnostic workup of acute cerebral Ischaemia. We report on a case of a comatose 53-year-old man who was brought to the emergency room after cardiopulmonary resuscitation. The CT of the brain showed a diffuse brain oedema with an explicit hypodense demarcation of all deep nuclei.

We report on a 61-year-old man, who was referred for a follow up study 14 years after remission of Hodgkin's disease. Computed tomography (CT) revealed multiple hypodense lesions throughout the liver, primary suggesting recurrent Hodgkin's disease.
