1 | Introduction
Nasal polyps are common in clinical practice. They are hyperplastic tissue masses on the surface of the nasal mucosa protruding from the nasal cavity or sinuses. The common symptoms are nasal obstruction or increased nasal secretions, which are more common in adults. They can be single or multiple. They are more common in maxillary sinus, ethmoid sinus, middle nasal meatus, middle turbinate, etc. At present, the location and range of polyps are often judged by imaging examination, and further pathological examination is often needed for clinical diagnosis. At present, 3.0T1H-MRS can analyze the press sequence spectrum of brain gliomas 1-2 and prostate cancer 3 in the elderly, and can obtain biochemical metabolic information of clinical value, It can correctly diagnose and analyze brain glioma and prostate cancer in the elderly. In this way, we use 3.0T1H-MRS to study nasal mucosa polyp. We find that the spectrum analysis plays an important role in the diagnosis of nasal mucosa polyp. The specific situation is as follows.
