Quantitative Doppler ultrasonographic flow velocity determinations are reported from 39 normal control subjects and 80 patients with angiographically documented peripheral arterial disease, in whom femoral, posterior tibial and dorsalis pedis arteries were studied. The mean control values of the most useful parameters were: femoral artery: peak forward(More)
Chronic arsenical intoxication can still be found in environmental and industrial settings. Symptoms of chronic arsenic intoxication include general pigmentation or focal "raindrop" pigmentation of the skin and the appearance of hyperkeratosis of the palms of the hands and soles of the feet. In addition to arsenic-related skin diseases including keratosis,(More)
BACKGROUND Choline metabolism is often abnormal in malignant brain tumors. METHODS Brain positron emission tomography (PET) imaging with F-18 fluorocholine (FCH) was performed on 2 patients with intracranial lesions suspected to be high-grade malignant gliomas on the basis of magnetic resonance (MR) imaging and multivoxel 1H-MR spectroscopic imaging(More)
PURPOSE To evaluate fluorine-18 fluorocholine (FCH) PET/CT for the detection of recurrent prostate cancer in relation to prostate-specific antigen (PSA) level. METHODS FCH PET/CT was performed in 50 patients with rising PSA levels at follow-up of primary treatment of prostate cancer (radical prostatectomy in 28, radiation therapy in 13, and brachytherapy(More)
Thallium brain single-photon emission computed tomography (SPECT) may be useful for differentiation of tumor recurrence from scar tissue and radiation necrosis and to predict low or high grade brain tumors. We report a case of an 11-year-old boy with recurrent oligodendroglioma who showed increased focal uptake of thallium-201 at the site of recurrence(More)
