【Medical Science】Understand "Various Radiology Examinations" in Seconds

The development of contemporary society has indeed brought many advances to the field of medical imaging, and has continuously improved the level of medical diagnosis and treatment. With the continuous advancement of science and technology, medical imaging, as an indispensable and important part of the medical field, plays an increasingly important role. In the radiology department, the widespread application of various imaging examination technologies provides doctors with intuitive and accurate information, helping doctors to diagnose the disease faster and develop corresponding treatment plans. Today, let us take a deeper look at the various examinations commonly used in the radiology department.

Introduction to various examinations in the hospital's radiology department:

The radiology department of a hospital is an important department in a medical institution, responsible for the diagnosis and treatment monitoring of diseases using various imaging technologies. The radiology department has a variety of examination items, including conventional X-ray examinations, CT scans, MR (magnetic resonance imaging), DSA (angiography), etc. Each examination method has its unique advantages and scope of application.

1. X-rays

X-ray is a common imaging examination method that can generate images of internal tissues and organs of the body by using X-rays. During the examination, the patient needs to stand, lie down or sit on the X-ray examination table. The doctor will use the X-ray machine to irradiate the patient's body parts from different angles to obtain clear images. X-rays can be used to examine lesions or abnormalities in bones, chest, abdomen, head and other parts. Common applications include the diagnosis of fractures, lung infections, tumors, joint degeneration and other diseases.

Traumatic fracture or suspected fracture:

Preferred method: X-ray

Reason: X-ray examination is convenient and inexpensive

If X-rays are not diagnostic: CT scan

Bone tumor suspected:

Preferred method: X-ray examination

Reason: X-ray is convenient and economical

Observe bone structure: X-rays have high spatial resolution and can clearly observe the trabecular structure

2. CT scan

CT (Computed Tomography) scanning is an advanced imaging technology that can generate detailed cross-sectional images of various parts of the human body by using X-rays and computer technology. In a CT scan, the patient needs to lie on a moving examination table, and multiple cross-sectional images are obtained by an X-ray beam that surrounds the patient. During the examination, the examination table will move slowly, and the machine will rotate around the patient to take images from multiple different angles. CT scans can be used to examine lesions or abnormalities in different parts of the body, such as the head, chest, abdomen, bones, etc., and are suitable for evaluating the diagnosis of tumors, vascular diseases, head injuries, intracranial hemorrhage and other lesions.

Bone degeneration in joints and spine (aging):

Preferred method: CT or MRI

Reason: CT and MRI can provide more detailed imaging information

If bone degeneration is accompanied by soft tissue damage, arthritis, etc.: MRI is the first choice

Cerebral hemorrhage:

Preferred method: CT scan

Reason: CT can clearly show brain hemorrhage, and the examination speed is fast, which helps to diagnose and treat brain hemorrhage in a timely manner.

Middle ear and mastoid diseases:

Preferred method: CT scan

Reason: CT scans can provide clear images of bone structure and can help doctors diagnose diseases related to the middle ear and mastoid, such as otitis media, mastoiditis, etc.

3. Magnetic resonance imaging (MRI)

Magnetic resonance imaging (MRI) is a very important medical imaging technique that uses magnetic fields and harmless radio waves to generate detailed images of human tissue structure. MRI can clearly display the structure of the brain, spinal cord, nerves and surrounding tissues, and help diagnose neurological diseases such as stroke, brain tumors, cerebral hemorrhage, and cerebral infarction; it can also provide clear images of the heart and blood vessels, and help diagnose heart and blood vessel diseases such as heart disease, aneurysm, and myocardial infarction. It can also examine the structure and function of internal organs such as the liver, kidneys, and pancreas, and assist in the diagnosis of tumors, cysts, inflammation and other internal organ diseases.

Inner ear diseases:

Method of choice: Magnetic resonance imaging

Reason: Magnetic resonance imaging has better resolution for the anatomical structure and soft tissue of the inner ear, and can help doctors diagnose inner ear diseases such as labyrinthitis and acoustic neuroma.

Inner ear hydrography (inner ear fluid imaging):

Suitable technology: Magnetic resonance imaging of the inner ear

Purpose: This technology can more clearly observe the fluid edema in the inner ear and help diagnose diseases such as inner ear fluid retention.

Encephalitis, meningitis, brain tumors, myelopathy, or spinal lesions affecting the spinal cord:

Method of choice: Magnetic resonance imaging

Reason: MRI has higher resolution and sensitivity for brain diseases such as inflammation and tumors, and can provide more detailed imaging information.

In short, doctors will choose appropriate examination methods based on the patient's condition and clinical needs. Radiologists provide clinicians with accurate diagnostic information through professional imaging analysis and interpretation. The various examination equipment and professional team of the hospital's radiology department provide patients with high-quality medical services.

The above is only a brief introduction to the various examinations in the hospital's radiology department. It only represents individuals. Each examination method has its own characteristics and scope of application. Patients should follow the doctor's instructions and cooperate with the examination process to ensure the accuracy and effectiveness of the examination results. I hope the above information can help you better understand the importance and application value of various examinations in the hospital's radiology department.
