Radiological examination is an examination to diagnose and support medical procedures. Radiological examination is useful to help doctors see the condition of the inside of the patient's body.
Radiological examination is carried out using a number of media, such as X-rays, magnetic fields, sound waves, and radioactive liquids. There are several types of radiological examinations, both to diagnose disease and to assist medical procedures, namely: Radiological examination is divided into two, namely diagnostic radiology and interventional radiology. Here is the explanation: Diagnostic radiology aims to determine the condition of the patient's internal organs, so that the disease suffered by the patient can be identified. The following are some of the diseases and conditions that can be detected by diagnostic radiology: Interventional radiology is performed to assist doctors in carrying out medical procedures, such as inserting a catheter or inserting small surgical instruments into the patient's body. Some of the procedures that may benefit from interventional radiology are: In addition to detecting disease and assisting medical procedures, doctors can also take advantage of radiological examinations to find out how the patient's body responds to treatment. There are several things that must be known before undergoing a radiological examination, namely: Before undergoing a radiological examination, it is important to follow the doctor's advice so that the patient gets optimal examination results. Depending on the type of radiological examination to be carried out, the patient's preparations include: As mentioned earlier, there are various types of radiological examinations. The following will briefly describe each type of radiological examination: X-ray examination uses a machine that emits X-ray radiation to display the inside of the patient's body in 2-dimensional images. This examination generally only lasts a few minutes. Depending on the part of the body being examined, the doctor may take pictures of the patient in a number of positions. In some conditions, the doctor will use a contrast fluid so that the resulting image becomes clearer. Fluoroscopy uses X-rays to display images of the patient's organs in video format. Generally, doctors run a fluoroscopy examination by first giving a contrast dye. Just like an X-ray examination, the doctor can ask the patient to change position in order to get a clearer picture. The length of the fluoroscopy examination depends on the part of the body being examined. Ultrasound examination is done by directing high-frequency sound waves to the patient's body part to be examined. These sound waves will bounce when they hit solid objects, such as internal organs or bones. The reflection of sound waves will be captured by a probe attached to the patient's body surface and processed by a computer into 2-dimensional or 3-dimensional images. An ultrasound examination generally lasts 20–40 minutes. CT scan examination aims to display images of the patient's internal organs more clearly from various angles. A CT scan uses an X-ray-emitting machine that is supported by a special computer system. CT scans can display detailed images of body organs that can be combined into 3-dimensional images. The entire stage of the CT scan usually lasts 20 minutes to 1 hour. Magnetic resonance imaging (MRI) aims to produce detailed images of the organs inside the patient's body. An MRI scan can last from 15 minutes to more than 1 hour. MRI uses magnetic field technology and radio waves, so it is safe from radiation. The images produced from MRI are also more detailed and clear when compared to other types of radiological examinations. Nuclear medicine examinations are carried out using a machine equipped with a gamma camera. The gamma camera functions to detect gamma rays in the patient's body. Gamma rays in the patient's body come from a radioactive liquid that was injected into the patient before the examination. The light is then processed by a computer into a 3-dimensional image for further analysis by a doctor. The following are some things that patients need to know after undergoing radiological examinations: Radiological examination is a safe procedure and rarely causes complications. However, there are still some risks that may occur as a result of undergoing radiology examinations, namely: Contrast fluid given during radiation exams can cause nausea, vomiting, itching, dizziness, and a metallic taste sensation in the mouth. In patients with renal impairment, the use of contrast fluids can even lead to acute renal failure. Although rare, contrast fluid can also cause a drastic drop in blood pressure, anaphylactic shock, and heart attack. A one-time CT scan tends to be safe for the patient. However, the risk of cancer due to radiation can increase if CT scans are performed repeatedly, especially in pediatric patients who undergo CT scans in the chest or abdomen. The magnetic field in an MRI machine can attract metal. Therefore, injuries can occur if the patient forgets to remove the jewelery before undergoing the MRI. The magnetic field of an MRI can also damage assistive devices, such as pacemakers.Indications for Radiological Examination
