What are the different types of cancer scanning?
Several types of medical imaging tests are used to diagnose cancer. These tests include displaying X -ray magnetic resonance imaging, computer tomography and positron emission tomography. Some of them can also help phase cancer, which means to evaluate how far the cancer has progressed and whether it was metastasized. Each type of cancer scans uses slightly different technology and results in the results of different accuracy and details. Two of these cancer tests are often performed simultaneously because some scanning have a synergistic effect when used together.
X -ray is the most basic test that can function as cancer. While X -ray is a useful diagnostic tool, but is not described in detail for accurate diagnosis and is not used for cancer. X -ray is one of the first diagnostic imaging tests that can be used to diagnose cancer, but almost always follows at least one more diagnostic scanning.
ComputerTomography, also referred to as CT scanning, uses X -ray technology, but uses other equipment to take X -rays from several different angles at the same time. This type of cancer scans can generate three -dimensional images of the body interior and is a much more useful diagnostic tool than one X -ray. The main disadvantage of scanning CT is that generated images are low contrast. In order to help correct this problem, a person undergoing a CT scan can receive intravenous contrasting dye inject so that the scanner can create more detailed images.
scans magnetic resonance, commonly called MRI scanning, generates body images by electromagnetic radiation. MRI scanning can produce images in more detail than CT scanning, with added advantage that MRI can generate high contrast images without the need for intravenous dye injections.
scanning positron emissions or PET scanning is the most ephemening Racange Skam in useFor detecting and staging Cancer. Unlike any other type of cancer scanning, PET scanning relies on the metabolic differences between malignant and non -signic cells to detect cancer in the body. This PET scan characteristics means that this particular test is more detailed and accurate than any other for cancer diagnosis.
Combination of PET scan with CT scan or MRI by scanning allows even more accurate and detailed results that can provide accurate cancer forecast. Positioning, size and metabolic activity of the tumor is essential because it affects the type of treatment that the patient can receive. These combined scanning are also very useful to determine how well the patient responds to specific treatment after its performance.
