+ γράφω "i write") is a radiological examination method that produces an image of the urinary bladder on an x-ray by filling it with a radiopaque substance that enters the bladder either descending (from the kidneys during excretory urography) or ascending (when introduced through the urethra). excretory urography is a radiographic method of examining the urinary tract based on the ability of the kidney to secrete certain radiopaque substances introduced into the body, resulting in an image of the kidneys and urinary tract on radiographs. concentrated iodine-containing (60-80%) solutions of sergosin, urografin, urotrast and others are used as radiopaque substances. the drug is administered intravenously by jet slowly (over 2-3 minutes). the amount of contrast is calculated by weight. retrograde pyelography is a non-invasive diagnostic method for examining the condition and function of the kidneys, during which a contrast agent is used. and some more additions irrigography (irrigoscopy) is an …

$scan), is a medical imaging technique used to obtain detailed internal images of the body. the personnel that perform ct scans are called radiographers or radiology technologists. evaluation of the quality of the x-ray image 1. image clarity and resolution sharpness: the image should clearly show fine details of the structure being examined. a blurry image can make it difficult for radiologists to make an accurate diagnosis. resolution: higher resolution is important for detecting small abnormalities such as fractures or tumors. low-resolution images might miss key features. 2. contrast and brightness contrast refers to the differrence in intensity between different areas of the image. adequate contrast helps to distinguish between different tissues, such as bone and soft tissue. brightness: proper brightness ensures that both dense (e.g., bone) and less dense areas (e.g., lungs) are visible without overexposing or underexposing the image. 3. exposure factors overexposure: can lead to loss of …$

$chnical issues like improper settings can lead to poor-quality images. film/detector quality: in traditional x-ray systems, film quality plays a big role, whereas in digital systems, the quality of the detector is key. evaluation of the quality of the x-ray image 7. radiation dose the amount of radiation used in imaging should be sufficient for a clear image but as low as possible to minimize the patient's exposure to radiation. 8. diagnostic relevance clinical context: the x-ray image should be assessed based on the clinical history and question that needs to be answered (e.g., identifying a fracture or detecting pneumonia). the quality of the image is considered good if it allows for accurate clinical interpretation. interpretability: a well-quality image should provide information that can be used to confirm or rule out conditions, depending on the clinical scenario. challenges in image quality assessment subjectivity: different radiologists or radiographers may have varying …$
