Effectiveness of Current Practices for Disinfecting Medical Equipment in a Radiology Department.

Purpose: To evaluate the effectiveness of routine, daily disinfection practices on the control of microorganisms on nuclear medicine equipment in a radiology department.

Methods: During phase 1, surface samples were collected from various sites in the nuclear medicine division of a radiology department at a single institution. These samples were transferred onto growth plates for evaluation and speciation by a clinical microbiologist.

Does the preparation and utilization of 99mTc-sulfur colloid affect the outcomes of breast lymphoscintigraphy?

Unlabelled: The purpose of this study was to determine whether certain factors in the preparation and use of (99m)Tc-sulfur colloid affected the number of sentinel lymph nodes (SLNs) detected during SLN mapping and during intraoperative SLN identification. The factors that were investigated included the use of a dry heat block versus a hot water bath to heat the (99m)Tc-sulfur colloid bulk vial, amount of (99m)TcOH4(-) added to form the sulfur colloid particles, time between the unit dose calibration and the injection of the dose, and breast quadrant in which the injection occurred.

Methods: Data were collected retrospectively and quantitatively analyzed from images and reports of 488 patients with breast cancer who had undergone SLN mapping and intraoperative SLN identification from January 1, 2008, to June 30, 2011, inclusive.

Position paper on the development of a middle level provider in nuclear medicine: the nuclear medicine practitioner.

The development of an educational program and credentialing structure to support and recognize an advanced level of the practice of nuclear medicine technology is now underway. This work parallels the efforts in many, if not most, health care disciplines as they seek to achieve the twin goals of developing enhanced career paths and providing the best possible patient care in an environment where science and technology can run roughshod over concepts taught in the classroom a mere decade ago. Education is key to both goals.

Prevalence and patterns of physiologic muscle uptake detected with whole-body 18F-FDG PET.

Unlabelled: Recently, the use of 18F-FDG PET has progressed rapidly as a standard diagnostic imaging tool in many types of cancer. The purpose of this study was to evaluate the patterns and prevalence of muscle uptake as a result of muscle activity shortly before the 18F-FDG injection or during the uptake phase.

Methods: From October 2002 to October 2003, whole-body 18F-FDG PET scans (4-min emission and 3-min transmission per bed position) were performed on 1,164 patients with known or suspected malignancy.
