PURPOSE To evaluate and compare the spin lock and magnetization transfer techniques in the differentiation of benign and malignant head and neck tumors at magnetic resonance (MR) imaging. MATERIALS AND METHODS Forty consecutive patients with histologically verified head and neck tumors (20 malignant and 20 benign tumors, including five infections) were(More)
OBJECTIVE The aim of this study was to evaluate the results of stapes surgery after 20 years of follow-up and to compare the results between large fenestra versus small fenestra stapedotomy. STUDY DESIGN Retrospective clinical study. SETTING Tertiary referral center (university hospital). PATIENTS One hundred forty-two patients with otosclerosis(More)
Venous malformations of the jugular veins are rare findings. Aneurysms and phlebectasias are the lesions most often reported. We report on an adult patient with an abruptly appearing large tumorous mass on the left side of the neck identified as a jugular vein aneurysm. Upon clinical examination with ultrasound, a lateral neck cyst was primarily suspected.(More)
Twenty-nine consecutive patients with a palpable unilateral tumor in the parotid gland region had scintigraphy 22-28 hr after they were injected with 111In-labeled monoclonal anti-carcinoembryonic antigen (CEA) antibody (F023C5). Two patients were imaged at 48 hr also, and one patient was imaged additionally with single-photon emission CT. Twenty-seven of(More)
Bleomycin (BLM) is a well known natural antibiotic. It is toxic to dividing cells and has been used for the treatment of several forms of cancer. BLM has been labeled with various cations, but most of them have turned out be unstable in in-vivo experiments. In-BLM demonstrated high bone marrow uptake, but using 111In-bleomycin complex (BLMC) formed at low(More)
BACKGROUND Of the acquired ear canal atresias, idiopathic, inflammatory, medial meatal, fibrotising otitis has been suggested as a distinct disease entity, for reasons of aetiology. OBJECTIVE To report three more cases of idiopathic, inflammatory, medial meatal, fibrotising otitis and to further consider the possible relationship between this condition(More)
Twenty-nine consecutive patients with palpable unilateral tumour in the parotid gland region were examined by planar scintigraphy at 22-28 h after injection of 111In-labelled monoclonal anti-CEA-antibody. Two patients were also examined with emission tomography. Twenty-seven of the patients were operated on within 2-3 weeks. The serum CEA concentration was(More)
Localization of primary tumors, metastases, or recurrences in 13 consecutive patients with histological verification of squamous cell or adenocarcinoma was made with radioimmunodetection using monoclonal radiolabeled anti-CEA antibody. All surgical specimens stained immunohistochemically, except one, were positive for CEA. Of the known 19 tumor sites 17(More)
The carotid body paraganglioma is a rare tumor that arises from the autonomic nervous chemoreceptor. It can be diagnosed by contrast angiography. A patient in whom a carotid body chemodectoma was imaged with In-111 labeled monoclonal anticarcinoembryonic antigen (anti-CEA) antibodies is described. There was marked accumulation of the antibody into the tumor(More)
