Usually, CT scan is needed during physical examination. Many people don't know much about CT scan. CT scan is a kind of examination instrument with complete functions. It is checked by electronic scanning. CT scan can detect many diseases. However, there are some precautions before CT scan.

Can I eat before a lung CT scan?

Lung CT has nothing to do with whether you are fasting or not, so you can rest assured. Guidance: It is recommended that you pay attention to rest and get enough sleep. Generally, CT scans in large comprehensive hospitals should be done by appointment. There are no other precautions and the results can be obtained on the same day.

What diseases can lung CT detect?

Any inspection method has its scope of application, and no inspection method is omnipotent. CT scans are good for blood flow, and enhanced scanning can improve resolution and increase the chances of detecting disease. However, CT is based on the principle of radiation detection and needs to be carried out after careful consideration. There are many methods for lung examination, and they need to be carried out in a targeted manner.

Chronic bronchitis. Chronic bronchitis refers to a chronic lung disease of the trachea, bronchial mucosa and surrounding tissues, a non-specific inflammation. If the patient coughs and produces sputum for more than 3 months each year for 2 consecutive years or longer, and other known causes of chronic cough can be excluded, chronic bronchitis can be diagnosed.

What can CT scan reveal?

Neurological disorders

Craniocerebral trauma, cerebral infarction, brain tumor, inflammation, degenerative diseases, congenital malformations, etc. are the earliest applied human systems, especially in the diagnosis of traumatic craniocerebral emergencies. They are routine and preferred examination methods, which can clearly show cerebral contusion, acute intracerebral hematoma, epidural and subdural hematoma, craniofacial fractures, intracranial metal foreign bodies, etc., and are more sensitive than any other method.

CT is of great value in diagnosing acute cerebrovascular diseases such as hypertensive cerebral hemorrhage, subarachnoid hemorrhage, cerebral aneurysm and arteriovenous malformation rupture bleeding, cerebral infarction, etc. Acute hemorrhage can be considered as the first choice examination. For acute cerebral infarction, especially those within 6 hours of onset, CT is not as sensitive as MRI.

Cardiovascular system

It can be used for the diagnosis of pericardial tumors, pericardial effusion, etc. CT has definite diagnostic significance for acute aortic dissecting aneurysm, especially enhanced scanning has characteristic manifestations and can make a qualitative diagnosis.

Chest lesions

It has a very satisfactory effect in displaying lung lesions and has a high diagnostic value for lung trauma, infectious lesions, tumors, etc. The display of tumors, lymph nodes and pleural lesions in the mediastinum is also satisfactory, and the relationship between lung masses and the mediastinum can be shown.

Abdominal organs

It can clearly display solid organs such as the liver, gallbladder, spleen, pancreas, kidneys, and adrenal glands. It can clearly show the exact anatomical location and degree of lesions for tumors, infections, and traumas. It is of great value for lesion staging, etc., and helps in the clinical formulation of treatment plans. It is especially important for surgical positioning in surgical departments, and has great value in the diagnosis and differential diagnosis of intra-abdominal masses.

Pelvic organs

There are abundant fat intervals between the pelvic organs, which can accurately show the invasion of tumors into adjacent tissues. Therefore, CT has become an important means for the diagnosis, clinical staging and radiotherapy planning of ovarian, cervical and uterine, bladder, seminal vesicle, prostate and rectal tumors.
