In a completely dark room, the tube was covered in black paper, and he noticed that a screen that was covered in florescent material became illuminated by the rays created from the glass tube. At the time, Röntgen was exploring how electrical rays can pass from an induction coil through a glass tube. Medical radiology all started when a man by the name of Wilhelm Röntgen discovered what is called the X-ray, in 1895. Here are some of the most common tests we offer at Independent Imaging: Knowing the differences of each of these imaging tests can help ease your mind and know what to expect. Therefore, if your doctor recommends that you are in need of specialized diagnostic imaging, it can be helpful to understand both how they work, and the common uses for the different types of imaging. Unfortunately, the thought of having these tests done can often make patients anxious, but it’s important to remember that diagnostic imaging is typically non-invasive and painless. Some of the most common types of diagnostic imaging tests besides X-rays are magnetic resonance imaging tests (MRIs), Computed Tomography scans (CT), and Ultrasound. A doctor may order one, or multiple tests, in order to help diagnose or rule out certain medical complications. Each creates images based on different technology. There are several different types of diagnostic imaging tests. However, there are different types of diagnostic imaging exams, where the resulting images, or pictures, will help your doctor in making an accurate diagnosis, and choosing the best treatment plan. Length of MRI Scanĭepending on the area of concern, an MRI test can last between 30 and 60 minutes.When doctors need to get a better look at what’s going on in their patient’s bodies, they will often refer them to receive some type of diagnostic imaging. During the scan, the technician will watch you from another room to ensure you are comfortable and give updates on the status of the exam. The dye helps the radiologist see certain areas more clearly. Some exams require a special dye (contrast), which is given through a vein (IV) in your hand or forearm before the test. What to expect during a MRIīefore an MRI procedure, you will be asked to remove all metal to avoid interaction with the magnet inside the MRI equipment. Instead, MRI images are generated by pulsing radio wave energy through the body to produce cross-sectional pictures of organs and internal structure in the body. MRIs are used to detect diseases or abnormalities throughout the body, such as brain aneurysms or tumors, but also are often used as a “second look” if other imaging scans provide inconclusive results. Request Appointment What Is Magnetic Resonance Imaging (MRI)? How does an MRI work? The contrast will be provided to you when you arrive for your test. Radiologists analyze the CT scan results to help diagnose disease or injury to:Ĭomplete scans usually take only a few minutes. This allows the radiologist to highlight certain areas for a clearer image. Often times you will be asked to drink a contrast for the CT scan. You will be asked to remain still during the exam to avoid blurred images. A computer creates many different CT scan images of the body, called slices, which can be viewed on a monitor by the radiologist. Once you are inside the scanner, the machine’s x-ray beam rotates around you. What to expect during a CT scanĭuring a CT scan procedure, you will be asked to lie on a table that slides into the center of the CT scanner. CT scans can also diagnose an infection, however they can also be used to guide a surgeon to the right area during a biopsy, identify masses and tumors, including cancer, and study blood vessels. A CT scan uses data from several x-ray images of structures inside the body and converts them into CT scan pictures. What Is a Computed Tomography (CT) Procedure? How does a CT scan work?ĭoctors use CT scans primarily to look at the soft tissues of the body and various organs. The length of the x-ray depends on the body part being examined however it typically takes a matter of minutes. This exam is painless, however it may require you to stand still for a short period of time which can cause temporary discomfort. These X-ray images, called “radiographs,” are a result of a shadow cast between the x-ray source and the x-ray detector to capture images of different tissues or bones inside the body. In this exam, an x-ray machine sends individual x-ray particles through the body, which are recorded as digital x-ray images on a computer. Doctors commonly use x-ray technology to diagnose broken bones, but can also detect pneumonia, types of cancers, and other developing conditions.
