UNLABELLED Radionuclide bone scanning (RNB) is considered to be the most practical screening technique for assessing the entire skeleton for skeletal metastases. However, RNB has been shown to be of lower sensitivity than MRI and CT in detecting osteolytic metastases. A prospective study was designed to evaluate the accuracy of planar RNB versus tomographic(More)
PURPOSE Previous studies have shown that bone metastases are revealed by magnetic resonance imaging (MRI) or bone marrow scintigraphy several months before they are visible by conventional bone scintigraphy (BS). We present a new approach for detecting bone metastases in patients with breast cancer. We compared findings obtained with fluoride ion (F-18) and(More)
Acute and chronic treatment of Chinese hamsters and mice with 5, 25 and 125 mg/kg isoniazid (INH) given by oral intubation did not enhance the chromosomal aberration frequencies in spermatogonia. The structural and numerical aberration rates remained in the range of spontaneous events even after the chronic treatment over 12 weeks with 3×125 mg/kg INH per(More)
PURPOSE We evaluated the frequency, distribution and appearance of benign lesions in 18F-PET scans. METHODS Between March 1996 and May 1997, 18F-PET scans were performed in 59 patients in addition to conventional planar bone scintigraphy. Eleven patients were subjected to additional SPECT imaging. The main indication was searching for bone metastases (58(More)
Plasma levels of the partial dopamine agonist, terguride, were measured by RIA in healthy volunteers after a single i. v. dose of 50 μg and on the first and seventh day of an oral treatment with 250 μg, 500 μg and 750 μg b. d. Basal and releasing hormone (TRH, GHRH, CRF, LHRH) — stimulated pituitary hormone secretion (PRL, TSH, GH, FSH, LH) and cortisol(More)
