What this CT scan says

This simple CT report doesn't say anything, but also takes into account your specific signs and symptoms.

Let's explain the ground-glass image.

Ground-glass opacity refers to mild lung density on CT images.

Heighten. Appears as a faint patchy hyperdense opacity in the ground-glass opacity of the lungs.

Blood vessels and bronchial tubes are faintly visible. This presentation reflects mild interstitial thickening or gas.

The lumen is not completely filled, which is a reversible change and mobility process. The pathological basis is:

Interstitial alveolar pyropyitis. That is, the alveolar septum has varying degrees of inflammatory cell infiltration into the alveoli.

There are protein substances and cell proliferation in the cavity, and there is reticular protein hyperplasia in the alveolar septum, but there is basically no collagen tissue to form interstitial fibrosis, and the alveolar tissue structure is maintained.

It has been reported in the literature that ground-glass opacities can occur in idiopathic pulmonary fibers.

It can also be seen in other interstitial lung diseases at all stages of the lesion and is not idiopathic pulmonary fibrosis.

The characteristic performance of dimensionalization is tIdiopathic pulmonary fibrosis presents with extensive ground-glass bilaterally.

Imaging with pulmonary interstitial fibrosis is more nonspecific interstitial pneumonia (NSIP), allergy.

Pneumonitis, desquamative interstitial pneumonia (DIP) is uncommon. Macdonald et al. argue.

The most important differentiator between NSIP and idiopathic pulmonary fibrosis is ground-glass opacity.

The proportion of patients with EC was high, and in its study, about 33% of patients with idiopathic pulmonary fibrosis grind.

The ratio of vitreous opaque opaque to reticular opacities is approximately the same, with 12% of patients having ground glass.

Glassy opaque opacity, NSIP and HRCT findings of idiopathic pulmonary fibrosis.

There is some overlap'87 It is important to point out that due to the presence of typical HRCT findings.

Lung biopsies were rarely performed in patients with idiopathic pulmonary fibrosis, so MacDonald et al. had selective bias in favor of patients with atypical HRCT findings.

The extent of ground-glass opacities is thought to be positively correlated with prognosis. Grind.

Vitreous opacities respond better to hormones with larger ranges, while smaller ones respond better.

Poor or no response. GAY et al. retrospectively analyzed 38 cases of pathologically confirmed idiopathia.

Studies in pulmonary fibrosis suggest that ground-glass opaque opacities are widely extensive.

The degree reflects the effect of **, and HRCT is more effective than pulmonary function tests and thoracotomy.

Biopsy results in better efficacy.

How old is the child, whether there is anemia, generally this lung CT can be clear that there is inflammation in the lungs, but the specific pathogen infection should be examined, pay attention to tuberculosis, viruses, pulmonary hemosiderosis, etc., and be hospitalized for a comprehensive examination.

Generally, this kind of lung CT can make it clear that there is inflammation in the lungs, but the specific pathogen infection should be checked for progression Do you have back pain Is it Press with your hands.

A CT scan can determine whether there is pneumonia or not, and the doctor will usually let you take an MRI if there is a problem. You obviously have inflammation, go to the hospital as soon as possible**.

It is an interstitial lesion of the lungs, and it is recommended to follow up with high-resolution CT of the chest after one month to see if the disease has progressed. As for whether it is idiopathic interstitial pneumonia, further investigation is even more necessary. Usually the interstitial lesions of the lungs will be well displayed on high-resolution CT, but there is still controversy about the understanding of this disease in China.

Inflammation of the lungs, or interstitial pulmonary fibrosis. You should go to the hospital as soon as possible for further examination,**.

CT is just a machine, or method, that can be used for a full body or a partial examination.

The CT machine is a computed tomography machine, which was developed from the X-ray machine. Its resolution and qualitative diagnostic accuracy are much higher than those of ordinary X-ray machines.

In general, CT can be used to detect all organic diseases, especially those with large differences in density, and make a qualitative diagnosis. However, the most suitable diseases for CT examination are brain diseases, among which the best effect is on tumors, hemorrhage and infarction, followed by mass lesions of abdominal parenchymal organs, such as tumors in liver, spleen, pancreas, kidney, prostate and other parts, and masses in breast, thyroid and other parts can also be displayed and diagnosed; The second is to examine the lumps in the chest, lungs, and heart chambers, and the masses in the spine, spinal cord, pelvis, gallbladder, uterus, etc. CT is slightly less effective in the examination of some diffuse inflammatory and degenerative lesions, such as hepatitis, CT examination is not of much value, and CT is not as good as endoscopy for the examination of gastrointestinal lesions.

CT is easy to detect tumors, lumps, hemorrhages, etc.; However, if the lesion is too small, especially if it is less than 6 mm, it is difficult to detect on CT.

The CT machine belongs to the radiation examination machine, so there is a certain amount of radiation damage, but the human body is subjected to very few X-rays, and the radiation received by each examination is only slightly higher than the general X-ray examination, which generally cannot cause damage, but blind multiple CT examinations are not good.

During pregnancy, abdominal CT examination should be done cautiously, and when other parts of the abdomen are examined, certain protective measures should also be taken to avoid the impact of X-rays on the fetus.

The landlord is relatively thin, which may be due to endocrine reasons, such as thyroid dysfunction, or gastrointestinal function. CT is not recommended. Instead, go to the internal medicine department and ask the doctor first. Find out the approximate cause and do further investigations.

The full name of CT is computed tomography, also known as computed tomography. The principle is X-ray, which is the same as X-ray, so CT will have a certain amount of radiation, and we must do a good job of protection. CT is more advanced than X-rays in that it can be scanned layer by layer, and its tissue resolution is higher.

In addition, we can quantitatively analyze the density of tissue, by measuring the CT value, the CT value from minus 1000 points to positive 1000, a total of 2000 cells, each grid is a CT value unit, we measure the density of the tissue by measuring the unit of CT value, to identify the nature of the lesion, which is very helpful for our diagnosis. In recent years, CT has developed rapidly, from the original single-row CT to multi-row CT, and now there are spectral CT, dual-source CT and volumetric CT, which greatly accelerates our scanning speed, scans thinner layer thickness, sees more clearly, and has higher resolution. Therefore, the application range of CT is becoming more and more extensive, and the radiation dose of CT is also greatly reduced under the same conditions, which is safe for the human body.

CT scan is a computed X-ray scan that can detect many diseases, such as examining the skull, checking whether there is cerebral hemorrhage, cerebral infarction, intracranial tumor, cerebral contusion caused by traumatic brain injury, subarachnoid hemorrhage, etc., as well as aneurysm, moyamoya disease and other diseases. CT of chest lesions is the first choice, which can check whether there is inflammation, tuberculosis, and tumors in the lungs, especially now for early lung cancer screening, which is checked by chest CT, which can detect precancerous lesions of early lung cancer. Enhancement tests in other areas, such as an abdominopelvic exam, can check for tumors.

CT can also examine blood vessels, such as pulmonary tethered obstruction and aortic dissection. Patients with trauma usually need emergency CT to see if there is any obvious organ rupture, hemorrhage, pneumothorax, etc. Therefore, CT has a great role and can detect many diseases, and its clinical application is also very important.

What is a CT scan? What diseases need to be CT scanned?

1. CT examination is a method of scanning the human body by X-ray to obtain a series of continuous cross-sectional images, and CT examination can be widely used in the screening and diagnosis of various diseases in all parts of the body, differential diagnosis and follow-up evaluation after the disease.

2. The main value of CT examination is the rapid diagnosis after trauma, the localization and characterization of inflammation and tumor lesions, the diagnosis of cardiovascular and cerebrovascular and peripheral vascular diseases, and the diagnosis of acute abdomen.

3. CT examination methods include plain scan and enhancement methods, the latter is mainly CT scan after injection of contrast agent, the purpose of which is to improve the accuracy of disease diagnosis.

4. However, there are certain limitations in CT examination, such as some small lesions should not be found; Qualitative diagnosis of certain diseases, including differential diagnosis of benign and malignant tumors, is difficult.

5. In addition, patients who are allergic to contrast media cannot be scanned. Since CT is an X-ray examination, there is a certain amount of ionizing radiation, so it should be used with caution in sensitive groups, such as pregnant women, people trying to get pregnant, and young children.

What is a CT scan? What diseases need to be CT scanned?

In the imaging report, we often see that the description of the lesion is followed by a CT value.

What does that mean? Is it better to have a lower number? Hear what the imaging doctor has to say.

Your questions don't seem to be complete, what about your **.

Middle-aged female, the lesion is located at the orbital apex, the boundary is clear, the circular hypodense shadow, **sexual, chronic, progressive exophthalmosis is considered to be cavernous sinus hemangioma. In addition, there may be schwannomas, fibrohistiocytoma, lymphomas, and venous malformations. As for orbital metastases, it is unlikely that the patient is healthy when the time is good.
