What are the examination items for nasopharyngeal carcinoma

Nasopharyngeal cancer can cause great harm to people's bodies, and the examination of nasopharyngeal cancer is an indispensable part of the treatment process of nasopharyngeal cancer. So, what are the examination items for nasopharyngeal cancer ? Let us take a look at the examination of nasopharyngeal cancer.

1. X-ray examination of nasopharyngeal carcinoma:

X-ray examinations of nasopharyngeal carcinoma patients can help understand the extent of the tumor and the destruction of the skull base, which is helpful for staging nasopharyngeal carcinoma, formulating radiotherapy plans, following up patients and evaluating prognosis. Commonly used X-ray examinations include lateral nasopharyngeal films and skull base films.

2. Radionuclide bone imaging diagnosis:

Radionuclide bone imaging is a non-invasive and highly sensitive diagnostic method. In the examination of nasopharyngeal carcinoma, it is generally believed that the positive coincidence rate of bone scan in diagnosing bone metastasis is 30% higher than that of X-ray film, and lesions can be detected 3-6 months earlier.

3. CT examination:

CT examination of nasopharyngeal carcinoma can help us understand the location of the tumor in the nasopharyngeal cavity, whether the lumen is deformed or asymmetric, and whether the pharyngeal recess is shallow or blocked. In addition, it can also show the invasion outside the nasopharyngeal cavity, such as the nasal cavity, oropharynx, parapharyngeal space, submental fossa, carotid sheath area, pterygopalatine fossa, maxillary sinus, ethmoid sinus, orbit, intracranial cavernous sinus, and whether there is metastasis in the posterior pharyngeal and cervical lymph nodes. Nasopharyngeal endoscopy has outstanding value in the diagnosis of tiny tumors in the cavity, while X-ray films and CT often cannot find such tiny tumors; however, most of the posterior wall and lateral wall tumors are submucosal invasive growths, which are difficult to be found by nasopharyngeal endoscopy, but can be clearly shown by lateral nasopharyngeal films and CT. CT shows lateral wall tumors more clearly than X-ray films.

4. B-type ultrasound examination:

B-mode ultrasound examination has been widely used in the diagnosis and treatment of nasopharyngeal carcinoma. The method is simple, non-invasive, and patients are willing to accept it. In nasopharyngeal carcinoma cases, it is mainly used to examine the liver, neck, retroperitoneal and pelvic lymph nodes to understand whether there is liver metastasis and lymph node density, whether there is cysticity, etc. This is one of the examinations for nasopharyngeal carcinoma.

The above is the introduction of nasopharyngeal cancer examination, for your reference only. Experts hope that everyone can choose a regular hospital to receive nasopharyngeal cancer examination to avoid serious consequences.
