Image processing is a method of improving or extracting information from a photograph by performing operations on it. It’s a type of signal processing in which a picture serves as the input, and the output is either that image or its characteristics/features.
Imaging can be used in various ways by clinicians to diagnose or monitor a medical condition. Imaging scans are relatively safe and pose few hazards, but knowing what to expect will help you feel more prepared. Several types of scans are used for different disorders, and the sort of scan your doctor recommends will depend on your symptoms. Below are the types of diagnostic imaging procedures that are available:
X-rays are the most common and widely available diagnostic imaging tool (radiographs). Even if you need more advanced tests, you’ll almost certainly have an x-ray first.
Between the x-ray machine and the photographic film or digital x-ray sensor is the section of your body photographed. You can reach out to the best scan center in your area for the procedure.
You must remain still as the equipment transmits electromagnetic waves (radiation) into your body for a limited period, exposing the film to reflect your inside structure. The amount of radiation emitted by x-rays is not hazardous, but your doctor will take extra precautions if you are pregnant.
A contrast substance or dye may be injected into a joint while x-rays are obtained in some cases. An “arthrogram” is a process that helps to delineate soft tissue components in the joint. When fluid is withdrawn or medication is injected into the joint, it may also confirm needle insertion.
X-rays may not provide as much detail as images created using more advanced techniques. They are, however, the most common imaging technique used to assess an orthopedic condition, and they are readily available in most doctors’ offices.
CT is a type of imaging that combines x-rays with computer technology to create a more detailed cross-sectional image of your body. Your doctor can use a CT scan to see the size, shape, and location of things deep inside your body, such as organs, tissues, and tumors. Before having a CT scan test, tell your doctor if you are pregnant.
If you have an issue with a small, bony structure or suffered severe trauma to the brain, spinal cord, chest, abdomen, or pelvis, you may need a CT scan. To make particular sections of your body stand out more, you may be given a dye or contrast substance.
Magnetic resonance imaging (MRI):
Another diagnostic imaging technology that provides cross-sectional images of your body is magnetic resonance imaging (MRI). MRI, unlike CT scans, does not involve the use of radiation. The MRI instrument takes high-resolution photographs of your bones and soft tissues using magnetic fields and a powerful computer. Tell your doctor if you have a pacemaker, implants, or other medical devices.
You will not experience any pain while having an MRI. However, the equipment may be loud. The pace at which your body’s various parts (tendons, ligaments, nerves, and so on) emit these vibrations is recorded by a computer, which then converts the data into a detailed, two-dimensional picture. You can reach out to an MRI scan in Coimbatore for the procedure.
Torn knee ligaments and cartilage, torn rotator cuffs, herniated discs, osteonecrosis, bone cancers, and other disorders can all be diagnosed using an MRI. The study could take anywhere from 30 to 60 minutes to complete. An MRI scan can be performed at a hospital or in an outpatient imaging center, just like a CT scan.
Other imaging tests include:
Ultrasound: Ultrasound is a type of imaging that uses high-frequency sound waves that reverberate about the body. It is non-invasive and painless, and it does not involve radiation. Ultrasound is most commonly used to detect blood clots, but it can also reveal other issues like a Baker’s cyst behind the knee or a rotator cuff rupture in the shoulder.
Bone scan and radiology tests are also other types of imaging tests that can help diagnose health issues.
