我院医疗设备增值概况解析

近年来，我院在医疗设备的引进中分别对不同类型的设备采取自筹、借贷、合作等多种方式，并在引进设备时区别对待大型基础性设备、效益设备、特色性专科设备等不同类型。并在市场预测、兼顾设备的超前性与医院的经济实力、注重从设备到技术的量本利分析等方面取得了经验，实现了设备技术循环和借贷额、合作设备金额的良性循环周期，使医院的设备总值翻了近两番，医疗技术及整体技术实力也前进了一大步。

Comparison of cellular and conventional dosimetry in assessing self-dose and cross-dose delivered to the cell nucleus by electron emissions of 99mTC, 123I, 111In, 67Ga and 201Tl

The radionuclides used in nuclear medicine imaging emit numerous mono-energetic electrons responsible for dose heterogeneity at the cellular level. S_self, the self-dose per unit cumulated activity (which results from the radionuclide located in the target cell), and S_cross, the cross-dose per unit cumulated activity (which comes from the surrounding cells) delivered to a target cell nucleus by electron emissions of technetium-99m, iodine-123, indium-111, gallium-67 and thallium-201 were computed at the cellular level. An unbounded close-packed hexagonal cell arrangement was assumed, with the same amount of radioactivity per cell. Various cell sizes and subcellular distributions of radioactivity (nucleus, cytoplasm and cell membrane) were simulated. The results were compared with those obtained using conventional dosimetry. S_self and S_cross values depended closely on cell dimensions. While the self-dose depended on the tracer distribution, the latter affected the cross-dose by less than 5%. When the tracer was on the cell membrane, the self-dose was particularly low compared to the cross-dose, as the self-dose to cross-dose ratio was always less than 11%. In the case of cytoplasmic or cell membrane distribution of radioactivity, conventional electron dosimetry slightly overestimated the dose absorbed by the target cell nucleus (by 1.08- to 1.7-fold). In contrast, conventional dosimetry strongly underestimated the absorbed dose (1.1- to 75-fold) when the radioactivity was located in the nucleus. The discrepancies between conventional and cellular dosimetry call for calculations at the cellular level for a better understanding of the biological effects of radionuclides used in diagnostic imaging.
