In 1988, Mark Weiser, a chief technologist at Xerox's Palo Alto Research Center, introduced the term ubiquitous computing, and heralded "the age of calm technology, when technology recedes into the background of our lives." This vision is now fast becoming a reality. Computing will soon be embedded everywhere in the fabric of our lives: in our bodies, phones, homes, and the environments in whic...

Over the years, many ideas have been handed down from one technologist to another about what to do and what not to do when fixing cells and tissues. This set of experiments takes into account certain conditions involving the age of the prepared primary fixative, length of time in primary fixative, length of time en bloc stain is on tissue cultured cells and the effect of washing the cells befor...

OBJECTIVE The relationship between age and effective renal plasma flow (ERPF) results, as measured in nuclear medicine, is well known. This paper explores the relationships among gender, age, and ERPF measurements. After reading this paper, the nuclear medicine technologist should be able to: (a) discuss the importance of establishing normal range values for ERPF that include age and gender var...

The object of this review is to provide information about (201)Tl-thallous chloride in radionuclide myocardial perfusion imaging. This technique has experienced a recent resurgence because of the shortage of (99m)Tc. After reading this article, the technologist will be able to describe the properties and uptake mechanism of (201)Tl, the procedure for myocardial perfusion imaging with this agent...

PURPOSE We aimed to evaluate the mammography image quality in İstanbul and to survey the awareness of mammography quality. MATERIALS AND METHODS Fifty-five mammography units in İstanbul were visited. The mammography image quality was evaluated using a standard American College of Radiology (ACR) accreditation phantom. The phantom contained 16 objects, and a score of at least 10 of 16 was acce...

A routine utilization review of our assay of high-density-lipoprotemn (HDL) cholesterol with a centrifugal analyzer (1) indicated that efficiency might be improved by an alternative HDL cholesterol method requiring less dedicated technologist time. The relatively few requests, coupled with our physicians’ expectation for turnaround, dictated that we could not use the centrifugal analyzer method...

The AutoMicrobic system (Vitek Systems, Inc., Hazelwood, Mo.) is a fully automated, computerized instrument. One of the most thoroughly studied aspects of the system is its ability to identify and quantify of nine most common urinary tract pathogens. The major advantages of the AutoMicrobic system are that the results of urine cultures are available in a fraction of the time required by convent...
