【摘要】：目的 :通過對(duì)比呼吸門控采集技術(shù)與常規(guī)采集技術(shù)所得的圖像,找出呼吸門控技術(shù)的優(yōu)勢(shì);監(jiān)測(cè)技師在使用該技術(shù)時(shí)所受的輻射劑量,從輻射防護(hù)角度驗(yàn)證該技術(shù)的可行性。方法:從2015年3月1日至8月30日間接受PET/CT檢查的患者中選擇50例符合條件的患者,入組條件為患者肺部孤立性結(jié)節(jié)。在常規(guī)PET采集之后加做呼吸門控技術(shù)采集,請(qǐng)1位主治醫(yī)師(博士)、1位主任醫(yī)師進(jìn)行盲測(cè),對(duì)比2次采集病灶的形態(tài)大小、最長(zhǎng)徑、體積以及標(biāo)準(zhǔn)攝取值(standard uptake value,SUV),出具詳細(xì)的核醫(yī)學(xué)報(bào)告;利用個(gè)人輻射檢測(cè)儀監(jiān)測(cè)技師使用該技術(shù)時(shí)所受的輻射劑量,利用統(tǒng)計(jì)學(xué)軟件進(jìn)行分析。結(jié)果:采用呼吸門控技術(shù)后,很大程度上減少了患者呼吸運(yùn)動(dòng)帶來的偽影,病灶顯示更清晰、邊緣更易于區(qū)分,使測(cè)量病灶的長(zhǎng)度、體積、SUV等結(jié)果更加準(zhǔn)確。參照放射人員輻射安全標(biāo)準(zhǔn),分析技師安裝和拆卸呼吸壓敏元件所受的輻射劑量符合安全規(guī)范。結(jié)論:在符合技師輻射劑量安全標(biāo)準(zhǔn)的前提下,對(duì)肺部孤立性結(jié)節(jié)的患者采用呼吸門控技術(shù)采集,是PET采集抵消呼吸運(yùn)動(dòng)偽影的一個(gè)可行性高、效果好的技術(shù),值得臨床廣泛開展應(yīng)用。
[Abstract]:Objective: to find out the advantages of respiratory gating technology by comparing the images obtained from respiratory gated acquisition technology and conventional acquisition technology, and to monitor the radiation dose received by technicians when using this technique. The feasibility of the technique was verified from the perspective of radiation protection. Methods: from March 1st 2015 to August 30th, 50 eligible patients were selected for indirect PET/CT examination. Pulmonary solitary nodule was selected as the condition. After routine PET acquisition, respiratory gating technique was added. One attending physician (doctor and one chief physician) was asked to carry out blind measurement, and the size and the longest diameter of the lesions were compared. The volume and standard uptake value of the standard uptake value are used to produce detailed nuclear medicine reports; the radiation doses received by technicians when using the technique are monitored by a personal radiation detector; and analyzed by statistical software. Results: after the use of respiratory gating technology, It greatly reduces the artifact caused by the patient's respiratory movement. The focus is clearly displayed and the edges are easier to distinguish. The results of measuring the length of the lesion, the volume of the SUV, etc., are more accurate, as per the radiation safety standards of the radiologist. It is analyzed that the radiation dose received by the technician in installing and disassembling the respiratory pressure sensitive element conforms to the safety specification. Conclusion: under the premise of meeting the safety standard of radiation dose of the technician, the patients with solitary pulmonary nodules were collected by respiratory gating technique. It is a feasible and effective technique for collecting and cancelling respiratory motion artifacts by PET, which is worthy of extensive clinical application.
