Abstract
BACKGROUND Many reports on glioblastoma multiforme discuss the prognostic impact of anatomical features such as cysts, necrotic changes, extent of edema or subependymal spread of tumor cells. In the present study, we examined different growth patterns and their possible relations to patient survival. METHODS To analyze whether anatomical characteristics are related to prognosis, we reviewed the prospectively collected pre- and postoperative MRIs of 83 patients in the 5-ALA study, provided by the 5-ALA Glioma Study Group. Following a standardized analytic work flow, the tumor volume and site, presence of necrosis or cysts, and perifocal edema were assessed preoperatively. In the same way, postoperative MRI and the MRI at first recurrence were analyzed. In addition, survival time of the patients was documented. RESULTS Median survival time of all 83 patients was 15.1 months (range 1.5 to 70.1, mean 18). The site or volume of glioblastoma, as well as the presence of intratumoral necrosis or cysts, did not exert a significant effect on survival time; 96.4 % of recurrences occurred within the former resection margin. Tumors with initial contact with the subependymal zone had multifocal or ventricular recurrences significantly more often. In patients with residual tumor on early postoperative MRI, the follow-up images displayed enlargement of the remnants in 91.9 % of these cases. CONCLUSIONS A merely anatomical analysis of the glioblastoma growth pattern cannot reliably provide prognostic information. The occurrence of most recurrences next to the resection margin and the high percentage of growing residual tumors underline the importance of complete resections.

Abstract
BACKGROUND Dacryocystographic evaluation of the location of stenoses of the lacrimal pathways was carried out in patients with epiphora to define the frequency and morphology of canalicular stenosis. PATIENTS AND METHODS Digital subtraction angiography (DSA) dacryocystograms of 55 consecutive patients with severe epiphora and stenoses of the lacrimal draining system were reviewed in a consensus between three evaluators to determine radiomorphologic criteria for the diagnosis of canalicular stenosis. In 9 cases 3D rotational dacryocystography was additionally used. RESULTS A total of 80 stenotic lesions were detected including 19 (24%) canalicular, 26 (32%) saccal and 35 (44%) ductal stenoses. In 9 of the patients 3D rotational dacryocystography was used to differentiate between canalicular (n=4) and saccal (n=5) stenosis. Increased resistance during continuous injection of contrast material and lack of distension of the distal ductal system were the main criteria for diagnosis of canalicular stenosis. CONCLUSION Presaccal stenoses accounted for nearly 25% of the stenoses found in this study. This type of stenosis occurs frequently and should not be overlooked on dacryocystography. 3D rotational dacryocystography may be helpful in unclear cases.

Abstract
Megadolichobasilar anomaly, a dilatant arteriopathy of the basilar artery attributable to chronic arterial hypertension, can cause cranial nerve compression syndromes of the cerebellopontine angle or infarcts of the vertebrobasilar circulation. In this paper, we report on a patient with known megadolichobasilar anomaly and a partially thrombosed fusiform aneurysm of the basilar artery, who presented with acute-onset vertigo and subsequent deafness due to thromboembolic occlusion of the labyrinthine artery. Because of the vascular origin of the patient's symptoms, his vertigo disappeared over time while the deafness persisted.

Abstract
This is a rare case of reversible high signal-intensity changes along the pyramidal tracts in a patient with reversible posterior leukoencephalopathy syndrome (RPLS). A 38-year-old man was admitted to hospital for loss of consciousness and generalized seizures. His systolic blood pressure was 220 mmHg. Neurological examination revealed bilateral pyramidal-tract signs, and paresis of the right arm. Initial MRI showed increased signal intensities on T2-weighted, FLAIR and diffusion-weighted imaging in the following regions: bilateral temporo-occipital white matter and cortex, dorsal parts of the lentiform nuclei, bilateral caudate nuclei and external capsule. High signal intensities were observed in the pyramidal tracts as well. On patient follow-up, MRI signal abnormalities and clinical symptoms were completely resolved after antihypertensive treatment.

Abstract
OBJECTIVE It is often difficult to decide whether a cystic brain lesion is a tumor or an abscess by means of conventional MRI techniques. The immediate diagnosis of a brain abscess is important for the patient's outcome. Our goal was to study the ability of diffusion-weighted imaging and calculation of the apparent diffusion coefficient (ADC) to differentiate between these two pathologies. PATIENTS AND METHODS Ten patients (five men, five women) with cystic brain lesions were examined with MRI. The ADC maps were calculated for each subject and the ADC value of each lesion was measured. Histology revealed glioblastoma multiforme in six patients and abscess in four patients. RESULTS All brain abscesses showed markedly hyperintense signal changes on diffusion-weighted imaging, whereas the appearance of glioblastoma varied from slightly hyperintense to hypointense signal conversion. The mean ADC value calculated in the six patients with cystic brain tumor was: 2.05 x 10 (-3) mm(2)/s (1.38-2.88 x 10 (-3) mm(2)/s). The mean ADC value of the four patients with brain abscess was: 0.57 x 10 (-3) mm(2)/s (0.38-0.77 x 10 (-3) mm(2)/s). CONCLUSION Diffusion-weighted imaging and calculation of ADC maps constitute a helpful tool to differentiate between cystic brain tumors and brain abscesses.

Abstract
The purpose of this study was to evaluate the feasibility and usability of different radiologic methods (single-slice computed tomography (CT), multi-slice CT and rotational tomography (RT)) for assessment of the position of cochlear implant electrodes. Cochlear implants in an isolated human temporal bone and in a complete formalin-fixed cadaver head were examined and the electrode position was determined. Subsequently, the labyrinth bone was isolated out of the cadaver head and histologically examined to compare the results of histology with imaging. Single-slice CT reliably identifies the electrode inside the human cochlea; however, due to the technically based large electrode artifact its position inside the cochlear spaces (e.g. electrode position in scala tympani or scala vestibuli) cannot be detected. Multi-slice CT of the cadaver head also showed artifacts that complicate the assessment of electrode position. Using RT the electrode artifact is small and therefore the electrode position within the cochlear spaces, scala tympani versus scala vestibuli, can be assessed. This technique was also applicable in a complete cadaver head, which is in contrast with former studies. In conclusion, CT allows the identification of electrode arrays inside the human cochlea. Multi-slice CT permits a much more precise depiction of the electrode inside the cochlea. RT alone has minimized electrode artifacts to a high extent and permits the assessment of the electrode position within the scala tympani or scala vestibuli. As RT was performed successfully in a complete cadaver head, further studies for evaluation of the intracochlear electrode position can now be performed in patients.

Abstract
We used dynamic CT to identify two different time constants of lung aeration and their individual contribution to the total increase in cross-sectional lung area in healthy and experimentally damaged lungs. In five healthy pigs, inflation and deflation between 0 and 50 cm H2O was imposed during dynamic (250 ms/image) CT acquisition, and repeated after experimental lung injury by saline lavage. The fractional areas of density ranges, which represent aerated lung parenchyma, were determined planimetrically, and their time for expansion during the manoeuvre was fitted using a bi-exponential model. Thus, two compartments, their sizes, i.e. their relative contributions to lung area aerated by the manoeuvre, and their specific time constants (tau) were sought. Healthy lungs were characterized best by a one-compartmental behaviour with one tau only, both during inflation (median tau=0.5 s; range 0.4-0.6 s) and deflation (1.2 s; 1.1-1.3 s). In damaged lungs two compartments were found both during inspiration and expiration, with 86% (78-87%) of the recruitable lung area following a short tau of 0.5 s (0.5-0.6), and 14% (13-22%) following a longer tau of 9.1 s (8-16.8 s) during inflation. During expiration, damaged lungs had a short tau of 0.8 s (0.5-1.0 s) for 94% (84-100%) of deflated lung area, and a longer tau of 26.5 s (7.1-34.3 s) for 6% (0-16%). We conclude that dynamic CT indicates the relative size and temporal behaviour of functional compartments in normal and abnormal lungs. Our findings suggest that after lung damage, cyclic ventilation with inspiratory periods of <10 s duration will not achieve maximum recruitment for a chosen inspiratory pressure. In ARDS, the short expiratory tau predisposes to atelectasis formation if expiratory times are >1 s.

Abstract
PURPOSE Aim of the study was to investigate alveolar inspiration and expiration using multiscan CT. Results of a visual assessment using a scoring system were compared with density ranges known to represent alveolar ventilation best. METHOD Pigs were examined before and after lavage-induced ARDS. All animals were examined using dynamic multiscan CT. The visual assessment was done by a scoring system proposed by Gattinoni. The results were compared with planimetric determination of defined density ranges. RESULTS In the healthy lung, the visual analysis showed higher scores at lower airway pressures with a marked gradient, whereas at higher pressures neither opacities nor gradients were observed. In ARDS-lungs, the scores were double as high as in healthy lungs at low pressures. At the same time the differences between inspiration and expiration were minor. There was good correlation between lung density measurements and lung opacities under different airway pressures. In healthy lungs, the greatest area increase is found between -910 and -700 HU. The biggest area growth in the ARDS-model is observed between -910 and -300 HU. CONCLUSION Dynamic multiscan CT allows for determining different ventilation-relevant lung compartments and lung density ranges.
