This is a question asked to me by a patient with pulmonary nodules, if you also have such concerns in front of your mobile phone, you can type "Yes" at the bottom of the video, and I will make a statistic, according to everyone's questions, for you to record popular science**.
This ** tells you how to follow up and observe the dynamic changes of nodules, so as to reduce the damage to the body while not affecting the observation effect. First of all, for the re-examination of pulmonary nodules, the thin-slice CT is basically done, and the radiation dose is about 6msv for each time, and the safe radiation dose that our human body can accept every year is within 50msv, which is converted to 3 to 5 CT times a year will not have adverse effects on the body.
However, the examination should be as regular as possible and the time interval should be even, such as every 3 months or half a year, rather than doing it intensively, which is more conducive to doctors to do dynamic observation and analysis. However, a short-term intensive CT examination is not only not helpful for the observation of the condition, but also the radiation received by the body cannot be effectively metabolized and discharged, which may not be as simple as the accumulation of radiation dose.
Therefore, if you follow the doctor's instructions and do a lung CT every 3 months, it will not irritate the nodules and even affect your health.
