UNLABELLED In amblyopia, the number of visual cortical neurons are reduced and abnormal or absent sensitivity to retinal light stimulation of the amblyopic eye is demonstrated. Ten amblyopic patients were studied to evaluate the response of the visual cortex to visual stimulation. METHODS All patients with unilateral amblyopia received 500-550 MBq(More)
OBJECTIVE Fever of unknown origin (FUO) is a challenge for the physician and needs use of clinical, laboratory, and imaging studies and also invasive and/or non-invasive interventions to detect the etiology. The aim of present study was to assess the role of FDG PET/CT in determining the etiology in patients with FUO. MATERIAL AND METHODS Twenty-four(More)
BACKGROUND In cases of thermal injuries it is always difficult to predict the extent of necrosis to the peripheral ischemic zone. Practically, full-thickness skin burn also affects the underlying muscle, panniculus carnosus, which adheres tightly to the skin. In this proposed model, the muscle which was always partly damaged also covers the ischemic zone of(More)
For many years it has been known that the sensitivity of bone scanning to the presence of destructive bony lesions favors its use in screening for bone metastases and osteomyelitis. More recently bone scanning has been routinely employed in evaluating benign skeletal pathology that may be the cause of low back pain. Bone scanning can play an important part(More)
UNLABELLED This article evaluates the clinical usefulness of 99mTc-ethylenedicysteine (EC) in patients with various renal disorders. In addition, extraction ratios of 99mTc-EC in five volunteers were also determined. METHODS Twenty patients were intravenously injected with 200 MBq 99mTc-EC and 2.5 MBq [131I]orthoiodohippurate (OIH) simultaneously and 11(More)
UNLABELLED Technetium-99m-EC has recently been introduced as an alternative renal tubular agent to 131I-ortho iodohippurate (OIH). It has been shown that 99mTc-EC clearance shows strong correlation with OIH clearance and it is possible to estimate effective renal plasma flow. In routine clinical studies, it is practical to use one or two plasma sample(More)
UNLABELLED We investigated the usefulness of 99mTc-methoxyisobutylisonitrile scintigraphy in patients with known or suspected pulmonary tuberculosis (PTB) in comparison with radiological and bacteriological findings. METHODS Thirty-six patients aged 13-59 yr were scanned 15 and 60 min after intravenous injection of 370 MBq (10 mCi)(More)
UNLABELLED Technetium-99m-ethylenedicysteine has recently been developed for renal function studies. The pharmacokinetics of 99mTc-EC were studied by constant infusion technique and compared with 99mTc-MAG3 and 131I-OIH in 11 patients with various renal disorders. METHODS After giving a 7.4 MBq 131I-OIH and 90-110 MBq 99mTc-EC or 99mTc-MAG3 bolus, a(More)
UNLABELLED Technetium-99m-labeled N,N-ethylenedicysteine (99mTc-EC) is a new renal imaging agent introduced as an alternative for 99mTc-labeled mercaptoacetyltriglycine (99mTc-MAG3), with similar renal excretion characteristics. To evaluate the diagnostic characteristics of this agent, a gamma camera study was performed. METHODS Sixteen patients with(More)
This retrospective clinical study was designed to analyze the impact of the initial surgical procedure on the survival of 1000 patients with differentiated thyroid cancer of follicular cell origin who had a thyroid operation and were followed for the 30 years between 1968 and 1998 (median 14 years) in an iodine-deficient region where goiter is endemic.(More)
