What is an MRI scan? An MRI collects detailed information about body organs and tissues by using a magnetic field and radio frequency waves.
What should I expect during an MRI scan? Patients are typically placed on the table and then slid into a cylinder-shaped scanner; they must remain still for a period of time until the scan is completed to ensure the picture does not come out blurry. While undergoing a scan, patients should not wear any metal items due to the magnetic field.
What is an MRI used for? MRI scans are used to diagnose a variety of conditions and are particularly useful for examining the brain and spinal cord.
What are the different types of MRI Scanners?
Open MRI: An MRI that is open on all four sides and uses magnetics placed above and below the patient to complete a scan. This type of scan is especially great for patients with a larger frame or claustrophobia.
High Field MRI: An MRI that is more powerful and faster than Open MRIs, therefore allowing a more precise diagnosis to be made. Because of its strong signals, these machines can image smaller areas of the body and provide concise details. They also cut scan time by as much as half, making them less-susceptible to patient movement.
What is a CT scan? A CT scan consists of multiple X-ray images each taken at a different angle to produce cross-sectional images of specific areas of the body. The scanner is shaped like a large doughnut on its side. CT is ideal for quickly examining patients that may have internal injuries from a traumatic event, such as a car accident.
What should I expect during a CT scan? CT scans are painless and take only a few minutes. Once ready for the scan, patients will lie down on a narrow table that will then glide through the scanner’s opening.
What is a CT used for? CT scans can detect many soft-tissue and bone abnormalities and can help doctors diagnose an array of pathological conditions like cancer and heart disease.
What is an X-ray? X-rays are a form of electromagnetic radiation used to produce images for diagnostic purposes.
What should I expect during an X-ray? Patients may be asked to change into scrubs and remove jewelry to prevent any interference while the image is being produced. The patient will be positioned in accordance to the desired viewing area and depending on the type of exposure, patients may have to hold their breath for a brief moment.
What is an ultrasound? During an ultrasound procedure, high-frequency sound waves are used to produce images of specific organs of the body for diagnostic purposes.
What should I expect during an ultrasound? Patients will lay face-up on an exam table while a clear gel is applied to the area that will be examined. A wand-like item, called a transducer, will sweep back-and-forth against the area to produce an image. Ultrasounds are minimally invasive and typically require little to no preparation prior to the exam.
What is an ultrasound used for? This diagnostic modality is used for a multitude of purposes including the early detection of carotid artery disease, liver disorders, and many different types of cancer.
