Dr. Corina Răileanu, Queen Maria Băneasa: “Each imaging method has a precise purpose, and the choice depends on the nature of the condition and the needs of the patient.”
Ultrasound and radiography are two fundamental imaging methods in modern medicine. Although both are used to explore the internal structures of the body, they operate on different principles, each having specific advantages and limits. Choosing the right method can have a major impact on the correct diagnosis and later treatment.
Dr. Corina Răileanu, primary physician in radiology and medical imaging at Regina Maria Baneasa, explains the essential differences between the two techniques and emphasizes the importance of using them according to the clinical needs of each patient.
How ultrasound and x -ray work
Ultrasound It is a non -invasive imaging method that uses ultrasound to generate real -time images of internal structures. Dr. Corina Răileanu explains: “The principle of ultrasound is based on the issuance of ultrasound by a special probe called transducer. These sound waves are reflected differently from the anatomical structures, and the ultrasound transforms these signals into visual images.”
It is an extremely versatile technique, used to examine the abdominal organs, glands, blood vessels and soft tissues, such as breast and thyroid gland. In addition, 3D and Doppler ultrasound add valuable details, being useful in pregnancy monitoring or evaluation of blood flow.
On the other hand, radiography Use x radiation to get two -dimensional images of dense tissues, such as bones or lungs. “Radiography is essential for the diagnosis of fractures, pulmonary disorders and even certain bone tumors,” “ emphasizes Dr. Răileanu. However, she mentions that x -ray is not as precise in the evaluation of soft tissues, such as the muscles or abdominal organs.
Patient safety: Ultrasound versus radiography
An essential aspect in choosing the imaging method is the safety of the patient. “The ultrasound is completely non -radiant, which makes it safe and suitable for pregnant women, children or for repeated examinations,” “ says Dr. Răileanu. Instead, radiography involves exposure to X -ray, which requires additional caution, especially in frequent examinations.
The radiation dose used in radiographs is reduced, but the exposure accumulated over time can increase the risk of conditions, including cancer. Therefore, radiographs should be performed only at the doctor’s recommendation and only when absolutely necessary.
When and for what conditions do ultrasound and x -ray are used
Ultrasound is preferred for examining internal organs, soft tissues and blood circulation. Dr. Răileanu explains: “This method can detect conditions such as biliary or urinary lithiasis, arthritis, abdominal tumors, mother nodules, thyroid pathologies and even muscle breaks.” It is also used to monitor pregnancy and guide minimally invasive procedures, such as biopsies.
Radiography indications
Radiography excels in evaluating the bone system and pulmonary disorders. Dr. Răileanu adds: “Fractures, dislocations, osteoporosis and pneumonia are some of the diagnoses where x -ray is indispensable. At the same time, this is used to identify visible renal calculations. ”
Technical limitations: Why ultrasound is better for soft tissues and x -ray for bones
These differences come from the physical principles of the two methods. “The ultrasound used in the ultrasound penetrate the soft tissues, but they are completely reflected by bone or air, which makes the lungs and the skeleton invisible to ultrasound,” explains Dr. Răileanu. In contrast, x -ray radiation is better absorbed by dense structures, such as bones, which allows their detailed visualization.
Special preparations for examinations
For ultrasound, training varies depending on the investigated area. “At abdominal ultrasound, the patient should avoid food for four hours and consume water before examining to have full bladder,” says Dr. Răileanu. Other types of ultrasound do not require special preparations.
Radiography, on the other hand, does not involve specific training, but patients should follow the doctor’s instructions, especially if contrast substances are used.
The complementarity of the two methods
There are situations in which ultrasound and radiography are completed for a more precise diagnosis. For example, in the case of a trauma, radiography can confirm a fracture, and ultrasound can examine any lesions of adjacent soft tissues. “The collaboration between these imaging methods and the specialists involved can optimize the diagnostic process,” “ says Dr. Răileanu.
In conclusion, ultrasound and radiography are essential tools in medical diagnosis, each having well -defined roles. The choice of the method depends on the type of affection, the safety of the patient and the goal of the investigation, and their correct use contributes significantly to improving the clinical results.
