Angiography - A Different Kind of Body Scan
As life loving people, we would do whatever it takes to find ways in avoiding, eliminating or even preventing diseases that would deteriorate and debilitate our bodies. In order to do so, concerned patients would go to hospitals and consult with their doctors for any preventive measures and efficient ways to remedy their sickness. In order to detect any malignancies in their bodies, patients are required to undergo full body scanning to identify and discover any possible tumors or organ swelling only found in the human anatomy's internal structure.
Common methods of partial and full body scanning are X-rays, ultrasound, MRI, and CT Scan. An X-Ray is a form of a partial body scan that uses electromagnetic radiation. X-rays are the first of its kind, being utilized in medical facilities dating back to the late 19th century. An X-ray machine captures imaging of the internal structure through electromagnetic frequency, and uses a photographic plate or film to catch the image. Ultrasound is another form of partial body scanning. This high frequency device uses sound pressure beyond human hearing to gather data and create sonic imaging to produce the needed image. With the use of sonic frequency, ultrasound machines do not produce radiation.
MRI, or Magnetic Resonance Imaging, is a tremendous breakthrough in medical technology. MRI is a partial body scan with the use of medical imaging technology based on radiological scanning to get a clear and highly detailed 3-dimensional visualization of internal structures. CT Scan, or Computed Tomography Scan, is a full body scan technique that also uses 3-Dimensional imaging technology to capture images of the body's internal structure. A CT Scan works similar to an X-Ray in terms of capturing data, but also works like an MRI where patients are situated on a table then slithered into the machine tunnel for a total body scan.
The full body scanning method that is quite unique is Angiography. Like the other medical imaging machines, Angiography is also used to visualize the internal structures, but focuses more details on the blood vessels, internal organs, and specific details on the veins, arteries and heart chambers. Angiography has a different scanning method by injecting a contrast agent into the blood vessel for the machine to get a clearer image capture. The process of capturing images is through fluoroscopy, an imaging technique that is obtaining real-time moving images, similar to colonoscopy.
Unlike in other medical imaging techniques, you can see the movement for each Angiographic procedure on the computer, and you could see the perfect details of every vein in the human body. The full body scan during Angiography is based on projectional radiography, a method similar to X-ray.
Angiography is recommended for those with issues with their cardiovascular and cardiorespiratory systems. Aside from these reasons, this technique is also advisable for those who are experiencing chronic pains in their abdomens, since most critical internal organs are situated within the abdomen or midsection.
Patients with previous CT Scans and MRI's may also opt for Angiography as an alternative for preventive screening and diagnosis.
