Lung cancer brain metastases can be detected by MRI.
MRI is the best imaging test to check for brain metastases when brain metastases are present in lung cancer.
When a tumor develops brain metastasis, it is most likely to be lung cancer. Brain metastasis MRI shows the lesion as T1WI is low signal and T2WI is high signal.
Because of the complexity of the pathology, there are more signal changes. The peripheral edema of the tumor is extensive and the occupying effect is more obvious. When injected with Gd-DTPA, the tumor has obvious enhancement, and the enhancement morphology is diverse, such as nodular and wreath-shaped.
When accompanied by hemorrhage of brain metastases, it is suggestive of lung cancer metastasis. NMR has a great advantage over CT, and the double-dose enhancement examination of NMR can find lesions of several millimeters. When combined with the history of lung cancer and the manifestations of nuclear magnetic examination, brain metastases can basically be clearly identified.
If there are relevant symptoms, one should go to the hospital as soon as possible to cooperate with active treatment to slow down the progression of the disease.
