Common respiratory diagnostic imaging techniques using radioisotopes are ventilation-perfusion, perfusion, aerosol inhalation and tumor scintigraphy. The special features of respiratory imaging diagnostic techniques using radioisotopes are the possibility of early detection of disease and the non-invasiveness of the procedure. Also, no patient effort is required. The kinds of isotopes used are as follows: ventilation-perfusion (133Xe, 13N, 99mTc-pseudogas), perfusion (131I, 99mTc), aerosol inhalation (99mTc), tumor (67Ga, 201Tl). The advantages of these procedures are expected to lead to further developments in respiratory examinations using radio isotopes.
常见的使用放射性同位素的呼吸诊断成像技术包括通气灌注、灌注、气溶胶吸入和肿瘤闪烁扫描。使用放射性同位素的呼吸成像诊断技术的特点是能够早期发现疾病且该检查无创。此外，无需患者费力。所使用的同位素种类如下：通气灌注（133氙、13氮、99m锝-假气体）、灌注（131碘、99m锝）、气溶胶吸入（99m锝）、肿瘤（67镓、201铊）。这些检查方法的优势有望推动放射性同位素在呼吸检查方面的进一步发展。
