Why did the CT scan still not confirm whether I had tuberculosis or not?

The CT room is based on images.

Clinical doctors rely on auxiliary examinations and their own experience.

None of them are wrong.

The CT room is faithful to the results of **, they just need to reflect the results.

The doctor wants to treat you and let you recover, naturally the most decided, and if tuberculosis is not well treated, it may cause serious consequences in the long run (only possible, but it cannot be ignored), but **, in addition to the long course of treatment, the risk is not very great (there is also a risk, that is, the drug "may" cause liver damage, but the doctor will let you have regular check-ups, so the risk is very small).

Therefore, there is nothing wrong with listening to the doctor, just cure the disease, and there is no need to investigate which is more accurate.

The presence of tuberculosis bacteria in sputum is the main basis for the diagnosis of pulmonary tuberculosis. A positive sputum is indicative of an open lesion.

Chest X-ray examination can not only detect pulmonary tuberculosis early, but also make judgments on the location, scope, nature, development and effect of the lesion, which is very helpful for deciding the best plan. Chest CT is helpful in detecting small or occult lesions and understanding the extent and composition of lesions.

Tuberculin (referred to as tuberculin) test:

OT test: less than 5mm is negative, 5 9mm is weakly positive, 10 19mm is positive, and more than 20mm or local blisters and necrosis are strong positive.

PPD test: used for clinical diagnosis, the average diameter of induration is 5 mm as a positive reaction.

X-ray, CT, and MRI are all imaging examinations, and only impression diagnosis can be made according to the morphology, characteristics and location of the lesion, while bacteriological and pathological examinations can be used as the basis for diagnosis. It is only a means for doctors to make a diagnosis, and doctors should diagnose a disease through its medical history, signs, and various examinations. You can't be mistakenly listening to the doctor.

Tuberculosis is highly likely, and it is best to do a sputum test and tuberculin skin test to confirm it.

According to the description of **, this situation is not serious, just a little bit, secondary tuberculosis, that is, you have had tuberculosis before, and now it may be ** or be infected again, whether the infection is contagious or not, it depends on the sputum test, the sputum test is negative or the infection is very weak, and the positive is infectious, but even if it is positive, the regular ** will not be contagious for a period of time.

Tuberculosis has a longer time, generally taking medicine, at least 6 months.

It is tuberculosis, but it should be old, if there are no symptoms such as cough, low-grade fever, night sweats, etc., it is recommended to follow up for observation, and do not take anti-tuberculosis drugs easily.

Chest X-ray conforms to the imaging characteristics of pulmonary tuberculosis, it is recommended to go to the tuberculosis prevention and control institution for treatment, if the sputum smear is negative, it is recommended that the infectious disease is not large, it is recommended to be routine for 6 months, the vast majority of patients can be **, ** is a normal person. Don't worry too much.

Is there any calcification?

It is reliable to go to a tuberculosis hospital.

Skin tests and blood draws are useless.

The most important thing is CT

1. PPD is the conjugate mycin test to see if there are tuberculosis bacteria in your body.

However, its specificity is not strong, that is, it is not the gold standard.

Sputum is positive for tuberculosis bacteria.

It means that it is tuberculosis and it is strongly contagious!

As for blood drawings, there are a lot of tests. Generally, routine blood tests and erythrocyte sedimentation rate (ESR) are performed. or C-reactive protein, carcinoembryonic antigen, etc., to rule out inflammation or tumors.

2. Unless it is.

Tuberculosis shedding period.

Sputum examination can quickly and accurately diagnose pulmonary tuberculosis, and other tuberculosis is not fast and accurate.

True. Unmistakable.

You can diagnose tuberculosis!!

This depends on symptoms, signs, conditions, and CT assistance.

3. There are no other special circumstances for tuberculosis without surgery, and it is completely possible to take medicine regularly throughout the whole process!!

CT alone cannot confirm pulmonary tuberculosis, and tuberculosis can only be confirmed by testing for Mycobacterium tuberculosis, and sputum culture is required. If you suspect that you have tuberculosis, it is recommended to go to the hospital for a sputum bacteria test, and at the same time take a chest CT, if the diagnosis is confirmed, you need to use anti-tuberculosis drugs under the guidance of a doctor, pay attention to good hygiene, open windows and ventilate frequently, drink more water, eat more vegetables and fruits, maintain a regular life, exercise more, and enhance body resistance.

Tuberculosis is an infectious disease of the lungs caused by Mycobacterium tuberculosis. 1. Chest X-ray or chest CT can be used to confirm the diagnosis. 2. Do a sputum smear test, if it is positive, you can confirm the diagnosis 3. Do an FD test (Fuda test), if it is positive, it is tuberculosis.

Guidance: The most important measures for tuberculosis are chemical drugs, and the commonly used drugs are isoniazid, rifampicin, streptomycin, pyrazinamide, ethambutol and amithiourea. The course of treatment is usually 6-8 months.

CT examination is an impact examination, the mentality of the organ can be more intuitive examination, but the examination of function can not be carried out completely, tuberculosis can be found through CT examination abnormal changes in the lungs, if it is necessary to determine the diagnosis, it is also necessary to cooperate with the culture of sputum bacteria. It is recommended that if pulmonary tuberculosis is diagnosed, it is necessary to adhere to a long course of anti-tuberculosis drugs**, such as isoniazid rifampicin** for more than half a year.

Whether or not a CT scan can confirm the diagnosis of pulmonary tuberculosis depends on the type of tuberculosis. In general, primary syndromes, secondary tuberculosis, and tuberculous pleurisy can be diagnosed by CT of both lungs. CT can identify the lesions and conditions of tuberculosis infection, and can find cloud-like patchy lesions, fibrosis, hyperplasia, exudation, cavitation, emphysema, atelectasis, pleural effusion and other pathological manifestations.

However, for hematogenous pulmonary tuberculosis and simple endobronchial tuberculosis, CT examination does not reveal any lung lesions and abnormal imaging findings, and the diagnosis may be missed. Therefore, sputum examination or culture of Mycobacterium tuberculosis is required, and bronchial fiberoptic endoscopy can be used if necessary to confirm the diagnosis.

It is unlikely, the most effective way to confirm tuberculosis is to find eosinophilus in the sputum, which is what we usually call sputum detection, and the clinical guidance of chest x-ray is also very important, which you do not have. Finally, a negative PPD means that your body has not been infected with Mycobacterium tuberculosis, so it can basically be said that you do not have tuberculosis. In the future, don't always listen to the wind and rain and scare yourself, okay?

1. CT examination can only find whether there are lesions in the lungs. If there is no lesion, pulmonary tuberculosis can be ruled out, and if there is a lesion, it is not certain whether it is pulmonary tuberculosis, and it is necessary to do tuberculin test, probe for acid-fast bacilli and other examinations to confirm the diagnosis.

2. There are many items for the diagnosis of tuberculosis, acid-fast bacilli are found in sputum, which is a reliable basis for diagnosis, and others include pathological examinations and tuberculosis antibodies.

3. You can take a chest X-ray (of course, it is best to do CT), if there is no lesion in the lungs, do not consider tuberculosis. It is not contagious.

4. If there is a lesion in the lungs, whether it will be contagious, it also depends on whether the sputum is excreted, if it is excreted, it is highly infectious. Otherwise, it is less contagious.

CT has great reference value for the diagnosis of pulmonary tuberculosis, but it also has misdiagnosis.

In order to obtain a correct diagnosis of pulmonary tuberculosis, it is necessary to combine medical history, physical examination, tuberculin (PPD) test, laboratory examination, X-ray examination and other information, among which the sputum tuberculosis examination is the most important, (because the sputum smear test positive pulmonary tuberculosis patients are able to excrete tuberculosis bacteria, so they are the most contagious and the main source of tuberculosis infection) can be comprehensively analyzed.

Your friend's tuberculosis is not necessarily contagious, but it is only contagious if it can be found in the sputum.

Even if your friend is infectious, you don't have to be infected, and if you have better resistance, you're less likely to be infected.

If you are infected, CT should be able to see it. If CT is fine, you can rest assured...
