The need for simple and accurate methods to measure renal function is self-evident. This increases as techniques intervention become available. demand evaluation of individual kidney has increased with its role in the diagnosis follow-up unilateral disease decision making conservative or surgical treatment based on residual function. nuclear medicine this area been inhibited by confusion about conflicting methodologies. report meant provide guidance those centers that would like initiate...
We measured right and left ventricular ejection fracttion (EF) from high frequency time-activity curves obtained during the initial passage of an intravenous bolus 99mTc (Sn) pyrophosphate. In 22 normal controls EF averaged 0.52 +/- 0.04 (SD). 24 acute anterior or lateral infarction patients was (0.56 0.10), while reduced (0.45 0.10, P less than 0.001 vs controls). 19 inferior also depressed (0.51 0.09, Among 7 with by scintigraphy, (0.39 0.05; normals; 0.01 without involvement). latter...
High-altitude illnesses encompass the pulmonary and cerebral syndromes that occur in nonacclimatized individuals after rapid ascent to high altitude.The most common syndrome is acute mountain sickness (AMS) which usually begins within a few hours of typically consists headache variably accompanied by loss appetite, nausea, vomiting, disturbed sleep, fatigue, dizziness.With millions travelers journeying altitudes every year sleeping above 2,500 m, wide-spread clinical condition.Risk factors...
The 2006 National Academy of Sciences Biologic Effects Ionizing Radiation (BEIR) VII report is a well-recognized and frequently cited source on the legitimacy linear no-threshold (LNT) model-a model entailing causal relationship between ionizing radiation human cancer risk. Linearity means that all causes explicitly excludes threshold below which radiogenic risk disappears. However, BEIR committee has erred in interpretation its selected literature; specifically, vitro data quoted fail to...
To assess the influence of lymphoscintigraphic and intraoperative gamma probe findings on surgical management melanoma to test reproducibility findings.After identification sentinel node, localization lymph node excision were performed in 25 patients. reproducibility, 13 patients underwent lymphoscintigraphy twice within 2-17 days. A modified preparation technetium-99m sulfur colloid with smaller particles than routinely obtained was injected intradermally around lesion. Dynamic flow images...
Parallel studies of the preparation Re and 99mTc agents aid in interpreting nature tracer radiopharmaceuticals. Aqueous solutions fac-[99mTc(CO)3(H2O)3]+ cation are gaining wide use readily prepared, but such fac-[Re(CO)3(H2O)3]+ (1) not so easily accessible. Herein we describe a new, reliable, straightforward aqueous 1, characterized by HPLC ESI-MS. Treatment 1 with thioether-bearing amino acids, AAH = S-methyl-l-cysteine (MECYSH), S-propyl-l-cysteine (PRCYSH), methionine (METH), gave high...
Specific quantitative measurements have been recommended to assist in the interpretation of technetium-99m mercaptoacetyltriglycine (MAG3) renal studies. Our objective was define sex- and age-specific normal ranges for these parameters.Data were obtained from a retrospective analysis 106 subjects who evaluated kidney donation. The MAG3 clearance calculated using common camera-based method. relative uptake, prevoid/postvoid postvoid/maximum count ratios determined whole-kidney regions...
