The aim of this study was to quantify imaging characteristics of fast fluid-attenuated inversion recovery (FLAIR) sequence in brain tumors compared with T1-postcontrast- and T2-sequences. Fast-FLAIR-, T2 fast spin echo (FSE)-, and T1 SE postcontrast images of 74 patients with intracranial neoplasms were analyzed. Four neuroradiologists rated signal(More)
To determine the impact of reduced hard-copy size on diagnostic performance of digital radiography, screen-film chest radiographs were compared with isodose digital storage phosphor radiographs in the detection of simulated nodules, fine pulmonary lines, and micronodular opacities superimposed on the chests of 10 healthy volunteers. Digital radiographs were(More)
Intracranial extraaxial cavernous angiomas are rare vascular malformations. Their occurrence at the geniculate ganglion of the facial nerve within the temporal bone is exceptional. The authors describe a 35-year-old man who developed a slowly progressing facial palsy. Initial cranial MR imaging showed no pathological findings, but 2 years later another MR(More)
New information technologies offer the possibility of major improvements in the professional education and advanced training of physicians. The web-based, multimedia teaching and learning application Schoolbook has been created and utilized for neuroradiology. Schoolbook is technically based as a content management system and is realized in a LAMP(More)
Several investigators have describedCT-negative low flow areas in TIA and stroke patients in the chronic phase. The emission tomographic SPECT image they employed has, in contrast to the xenon CT method, no direct relation to the x-ray transmission CT scan. The aim of our study was to study the phenomenon ofCT-negative low flow areas using the xenon CT(More)
Our experiences in 55 patients suffering from orbitofrontal injuries are discussed. The prognosis is determined by the severity of the brain injuries and the cerebral complications. The relation of fronto-basal, orbital, and maxillofacial fractures to lesions of the brain tissue and contents of the orbita is best demonstrated in high-resolution CT scan.(More)
The aim of the following study was to assess the impact of dose alterations on the detection of catheters. We compared the performance of well-exposed conventional and digital portable chest radiographs in the detection of thin catheters and tested the influences of dose alterations. Portable chest radiographs of 20 patients were obtained with conventional(More)
BACKGROUND Renal transplant recipients frequently experience neurological complications. Whereas ischemic stroke, cerebral haemorrhage or hypertensive encephalopathy often result from vascular alterations prior to transplantation, other cerebral diseases like CNS infections, primary brain tumors and drug induced neurotoxicity may develop as consequences of(More)
We report a case of fractured occipital condyle caused by minor trauma accompanied by light pain on palpation at the lateral cervical trigonum. A 15-year-old boy complained of nuchal pain, particularly pain on palpation at the left lateral cervical trigonum in the absence of neurologic deficits after head deceleration trauma. Computed tomography(More)
BACKGROUND Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) is an inflammatory disorder of the central nervous system; it has only recently been defined and to date has received only limited attention. Its cause is as yet unknown. The pathologic characteristics are infiltration of T lymphocytes into(More)
