Our first introduction to medical imaging occurs when a doctor asks us to have an x-ray or scan to investigate an injury, pain or symptom that cannot otherwise be explained. We can be overwhelmed when we see how complicated, large and noisy some of the equipment is.Many different types of examinations can be performed to investigate conditions and injuries. Sometimes more than one of the following medical imaging techniques is required to enable doctors to offer the best advice on treatment options.Computed tomography (CT):While this is happening, the patient is lying on a special CT imaging table that is allowing the x-ray beam through. The x-ray beam is shaped similar to a hand-held fan and is often described as a fan beam. There are multiple digital detectors located within this circular gantry that continually identify the energy of the x-ray photons that exit the patient.The motion of the table and patient moving through the gantry allows images to be reconstructed as slices (or tomographs) of human tissue. The most common CT exam is to scan a patient’s chest, abdomen and pelvis, and the most common reason for this is to identify the spread of cancer. “X-ray dyes” are injected into patients to identify cancer when using CT imaging, as the cancer tissue will absorb the “x-ray dye” and be more obvious on the image., Magnetic resonance imaging (MRI)-MRI uses a combination of a powerful cylindrical magnet and radiofrequency waves to generate an image of the body. It’s quite loud and patients must be wearing suitable hearing protection devices such as earplugs or headphones (where relaxing music can be listened to).Patients normally lie within the magnet cylinder, and a frame (which works like an antennae) is placed around the body area needing to be imaged, as close as possible, so the maximum possible signal can be detected in order to reconstruct highly detailed images. Our body contains hydrogen, so a radiofrequency is transmitted into the body at the frequency that will cause hydrogen atoms to oscillate. When the radiofrequency is switched off, the hydrogen atoms continue to oscillate and the frequency of this oscillation is detected by the frame or antennae., Positron emission tomography (PET)- The imaging techniques used with x-rays, CT and MRI, are mostly designed to observe structural information – this includes the arrangement of anatomy and the location of disease or injuries. PET imaging is a unique imaging process, as it can identify and image functional information such as metabolic (the converting of energy) or chemical processes of internal body organs.To do this, radioactive substances need to be injected into patients and these are chemically bonded to compounds used by our organs (such as glucose) or molecules that bind to specific receptors or specific types of cells (such as proteins).These radioactive substances emit gamma rays (another form of ionizing radiation). From their location within the body, the gamma rays pass through tissue and exit the body where they are detected by a PET scanner containing a gamma camera while the patient is lying still.The PET scanner detects the gamma rays, converts their intensity or strength into an electrical signal and then reconstructs an image based on this intensity. The detectors are arranged around a patient’s body so the originating location of the gamma rays within the patient can be calculated using mathematical processes.PET imaging is excellent for identifying the activity of tumours within organs that cannot be structurally identified with other imaging techniques., Ultrasound- Ultrasound uses sound waves to generate a medical image of human anatomy, and has no known detrimental effects. The frequency of ultrasound is higher than the sound wave frequencies that can be detected by human hearing. Sound waves can only travel through a medium, so a water-based gel needs to be applied to the skin, which allows the ultrasound to be transmitted from the transducer (or probe - the thing that’s moved over the area being scanned) into the body.Ultrasound reflects sound waves differently from all the different tissues within the body, the more dense a tissue is, the more sound waves are reflected and returned to the transducer. Where tissue is less dense, part of the sound waves will be returned to the transducer and part of the ultrasound will be transmitted through this tissue until it reaches a different type of tissue and the process continues (partly reflected and partly transmitted).When ultrasound waves return to the transducer, the sound waves are converted into an electrical signal, which is then digitised and reconstructed as an image. The image is formed by calculating the distance from where the reflected sound waves interacted with tissue and the transducer, and is calculated by knowing that in human tissue, ultrasound travels at approximately 1,540 metres per second.For many ultrasound imaging examinations, patients are asked to hold their breath so internal organs remain still while imaging is taking place. They may also be asked to move into certain positions.In addition to providing structural information on how anatomy is arranged, ultrasound has the added benefit of providing biomechanical and functional information, as it can also image in real time and observe muscles and tendons moving.Tabeebak Qatar provides you with telephone number of other scans in Qatar, Address of other scans in Qatar, Email of other scans in Qatar, website of other scans in Qatar, and More details about other scans in Qatar.
