Liver Biopsy – When is it recommended, and how is the examination performed?
The liver biopsy is a medical procedure used to obtain samples of liver tissue, and it is now considered a common routine intervention. During the procedure, a tissue cylinder is obtained from the liver tissue or from lesions observed in the liver, which is then sent for histological examination. The sampling is typically guided by imaging techniques such as ultrasound or CT, ensuring accurate localization. The purpose of the liver biopsy is to enable the diagnosis of liver diseases, especially when other tests do not provide clear answers regarding the causes of the disease. Through histological examination, the type and severity of the disease can be determined, which can assist…

Diagnostic Procedures Involving Radiation – Should We Really Be Concerned About Medical Examinations?
During medical diagnostic procedures, patients are exposed to various ionizing radiations, which can evoke unwarranted fears in many individuals. X-rays, CT scans, or isotope examinations, which involve radiation exposure, are generally safe when appropriate protocols are followed. However, it is worth understanding that these procedures are planned and controlled, so the effects of radiation can be well defined, and the risk can be considered significantly lower compared to unexpected radiation accidents. Sources of medical radiation exposure include diagnostic X-rays, isotope diagnostic examinations, and radiotherapy, which can be conducted with external or internal sources. These procedures are strictly regulated, which reduces the likelihood of accidents. Radiation accidents, which can most commonly…

Transesophageal Echocardiography (TEE)
The health and function of the heart play a crucial role in the quality of human life. With the continuous advancement of medicine, the methods for assessing and diagnosing the condition of the heart are becoming increasingly sophisticated. One of the most widespread and reliable procedures is echocardiography, which aids in the detailed understanding of the heart and large vessels’ condition. Types of Echocardiography There are two main types of echocardiography: transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE). TTE is the most common and widely used method, where the examination is performed through the chest. This non-invasive procedure allows for detailed observation of the heart and large vessels without requiring…

Ocular melanoma – Symptoms, diagnostic procedures, and therapies
The malignant melanoma, although rarely developing in the eye area, is an extremely aggressive and rapidly spreading tumor. This type of cancer is particularly dangerous in the eye, as it is often detectable only in late stages. In some cases, the tumor can be seen with the naked eye, but in most cases, it is discovered only during a fundus examination. Early diagnosis plays a key role in the success of treatment, allowing the disease to be effectively managed even in its initial stages. Types of Eye Tumors Eye tumors can be classified into two main categories: primary and secondary tumors. Primary tumors develop from the eye’s own tissues, while…
