We present a 55-year old male patient who was subjected to whole body skeletal scintigraphy for metastatic work up of urinary bladder cancer. Whole body 99mTc-methylene diphosphonate (MDP) skeletal scintigraphy was performed. That revealed no skeletal metastasis in the entire body skeleton and normally visualized left kidney with empty right renal fossa. Additionally tracer activity ...

ansi/ashrae 110-95 protocol is a widely acceptable method to assess the performance of laboratory hoods. in this test, sulfur hexafluoride (sf6) is applied as a tracer gas to quantitatively evaluate the performance of laboratory hoods. the environmentally hostile characteristics of sf6 as well as its cost are the major concerns. in the present study, the substitution of ethylene with sf6 in the...

conclusions the results of this study led to the identification of many of the errors and conditions that affect the performance of controllers, providing the ability to define safety and ergonomic interventions to reduce the risk of human error. therefore, the results of this study can be a basis for planning atm to prioritize prevention programs and safety enhancement results the analysis of ...

Skeletal involvement is the second most common site of metastases after lymph nodal metastases in patients with prostate cancer. The skeletal metastases from prostate cancer are osteoblastic in nature and show increased tracer avidity on the bone scan. Focal tracer avid lesion in skeleton especially in skull requires the careful examination by further investigation. The patients with skull meta...

the production and application of pet tracers has been a unique step in the progress of nuclear medicine in last two decades. the most important pet tracers include f-18, c-11 and n-13 radioisotopes and many nuclear medicine centers throughout the globe are using them. however some new tracers are under their way to the mass administration, currently being in the clinical trials or preliminary ...

  Although each subdivision of primary somatosensory cortex (SI) receives dense input from the thalamus, but the exact location and type of information that the fibers convey have not been identified yet. In the present study, the exact source of thalamocortical fibers to areas 2 and 3b was investigated using tract-tracing techniques. Following injection of tracer into area 3b, labeled neurons ...
