The object of our study was to evaluate the intra- and interobserver reproducibility of the interpretation of CT examinations of laryngeal carcinoma. The CT examinations of 100 laryngeal cancers were retrospectively reviewed twice by two independent reviewers. Involvement of different structures was assessed, using a standard scoring form. Statistical(More)
To evaluate the efficacy of a gradient-echo sequence (3DFT-CISS) in the diagnosis of acoustic neuromas, two independent observers twice reviewed the images of the temporal bones of 83 patients. Contrast-enhanced T1-weighted spin echo images were used as the reference, showing 18 acoustic neuromas, including 5 purely intracanalicular and one(More)
PURPOSE To investigate the intra- and interobserver variability, as well as the intra- and interpatient variability of CT-determined tumour perfusion in head and neck tumours, and to evaluate the preliminary value of this parameter as predictive factor of local failure after treatment by definitive radiotherapy. MATERIALS AND METHODS In 41 patients the(More)
In 18 patients the perfusion of a malignant head and neck tumour was estimated using contrast enhanced dynamic computed tomography. The mean estimated perfusion was 75.5 ml/100 g/min, varying between 27.9 and 131.9. Eleven patients were treated with radiation therapy; the obtained perfusion rates were significantly different between tumours with a(More)
We evaluated the clinical and radiological findings in 35 patients with submucosal laryngeal masses. The presenting symptoms were hoarseness, stridor, dysphagia and external neck mass. In 20 cases an important delay between the onset of symptoms and direct laryngoscopy was found. There was a considerable delay between laryngoscopy and definitive diagnosis(More)
Hoarseness has a broad range of etiologies, and in most cases a diagnosis can be made by recording an accurate history and by conducting a thorough physical examination. This paper will present an overview of the more common voice disorders and explain in which cases imaging studies such as computed tomography or magnetic resonance imaging are necessary.(More)
The purpose of this study was to estimate the volume variability of the preepiglottic and paraglottic space in the normal larynx. In 23 adult patients (12 women, 11 men), a spiral CT acquisition through the larynx was obtained. No laryngeal pathology was observed. The area of the this submucosal fat space was estimated on each slice by semi-automatic(More)
A rare case of an isolated unilateral hypoglossal nerve palsy in a 61-year-old man is reported. Imaging showed a dissection of the extracranial internal carotid artery. The expansion of the circumference of the artery causes compression of the hypoglossal nerve resulting in a palsy. To the best of our knowledge this disorder has twice been dealt with in the(More)
