Can cirrhosis be detected by ultrasound B?
If there are signs of hardening in the liver, which we call cirrhosis, an ultrasound, specifically a hepatobiliary ultrasound, can detect it. Especially in the middle and late stages, cirrhosis has some characteristic features on an ultrasound. First, one can observe the size of the liver. By the middle and late stages, the liver usually shrinks—a slight enlargement may occur early on, but it generally progressively diminishes. Additionally, the texture of the liver becomes harder, and through the ultrasound, the texture appears uneven with a bumpy feeling, or in other words, there can be seen a diffuse and uneven echo. However, for early-stage cirrhosis, a standard ultrasound may not be as sensitive. Nowadays, there are digital liver ultrasounds specifically designed to measure the degree of liver hardness, which provide objective data to help diagnose more sensitively and objectively. This method can definitely detect the condition.
Tuberculosis X-ray Chest Radiograph Manifestations
If it is tuberculosis, it is generally visible on an X-ray chest film. Of course, some especially early-stage or tiny lesions might not be detected except by CT. However, typical cases of tuberculosis can be diagnosed with a chest X-ray. Often, on the chest X-ray, the apices of both lungs—the uppermost parts—might show cloud-like, vague shadowy areas that are slightly brighter than the normal lung tissue but with unclear edges. Additionally, there are some cases of secondary tuberculosis, which are more severe, featuring tuberculomas which are more evenly dense and have smoother edges. These can be seen in the lungs. However, such typical severe tuberculomas are becoming less common clinically because medications are used more promptly now, and people seek treatment in a timely manner. Cases like chronic fibrocavitary tuberculosis are becoming increasingly rare, mostly seen in older patients who have been on medication for many years.
Can cholecystitis be detected by color ultrasound?
If there is gallbladder cancer, usually an ultrasonography of the liver and gallbladder or the upper abdomen can detect it. Conditions such as gallbladder cancer or liver cancer are often initially discovered and diagnosed through ultrasound. Of course, the final confirmation of diagnosis is usually achieved through pathological examination after surgery. However, in terms of initial diagnosis, it is very common to identify these conditions through ultrasound. Gallbladder cancer typically presents certain characteristic changes, such as obvious thickening of the gallbladder wall, extensive thickening including sclerosis, and significant soft tissue mass growth extending to and adhering to the liver, which are strong indicators of gallbladder cancer. Additionally, a large polyp may be seen inside the gallbladder, and surgical removal at this stage may diagnose early gallbladder cancer.
Is it good for a newborn to have a chest X-ray for pneumonia?
If a newborn exhibits symptoms such as fever or difficulty breathing, and pneumonia is suspected, it is essential to take a chest X-ray. Although the child is very young and just born, and despite the presence of certain radiation from the chest X-ray, the pros and cons must be weighed. For the sake of an accurate diagnosis and timely medication treatment, a chest X-ray is necessary. Unlike adult pneumonia, neonatal pneumonia progresses very rapidly. If the medication is not administered promptly and the diagnosis is uncertain, the condition can easily be delayed and progress too quickly. Thus, at this time, concerns about radiation should be set aside, and a chest X-ray is definitely needed. If the chest X-ray does not confirm the diagnosis, even conducting a CT scan might be necessary. It is crucial to clarify the diagnosis quickly and start treatment promptly. Because neonatal pneumonia is truly different from adult pneumonia, it progresses very rapidly and can potentially lead to severe complications like sepsis and shock, which are very dangerous. (Medication should be used under the guidance of a professional doctor.)
