INTRODUCTION TO RADIOLOGIC TECHNOLOGY SECTION 2 DR: WALAA WAHID; ASSISTANT LECTURER  WHAT IS RADIATION ?? RADIOLOGY &  Ultrasound An ultrasound scan uses high-frequency sound waves to make an image of a person's internal body structures. Doctors commonly use ultrasound to study a developing fetus (unborn baby), a person's abdominal and pelvic organs, muscles and tendons, or their heart and blood vessels.  Ultrasound modes M-mode has a high frame rate and therefore is useful for fast moving objects, function of motion. In B-mode or 2D imaging the x-axis is depth, the z-axis is amplitude and there is no y-axis. A line of B-mode data is transmitted in a line through the tissue, simplest type function of depth Doppler mode, used for blood flow visualization  3D US 3D Ultrasound' refers to a technique that can demonstrate the face of a baby and provide a reliable diagnosis of fetal gender by acquiring a volume data set with different ways of image  4D US A 4D ultrasound is similar to a 3D ultrasound, except it displays the images of the baby in a live- streaming video. The images put together shows the movement of the baby's body parts like their heart walls or https://www.google.com/url?sa=i&url=https%3A%2F%2F4babyultrasound.com %2Fhow-3d-and-4d-ultrasounds-work %2F&psig=AOvVaw2Y05mwz4gsRwmGHvyifpJb&ust=1729109726947000&source=im ages&cd=vfe&opi=89978449&ved=0CBQQjhxqFwoTCICrz_SZkYkDFQAAAAAdAAAAA BAE  ELASTOGRAPHY Elastography is a non- invasive medical imaging technique that helps determine the stiffness of organs and other structures in your body. It is most commonly used to assess  Computed Tomography A CT scan is a diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce images of the inside of the body. It shows detailed images of any part of the body, including the bones, muscles, fat, organs and blood vessels. CT scans are more detailed than standard X-rays.  MRI Magnetic resonance imaging (MRI) is a type of scan that uses strong magnetic fields and radio waves to produce detailed images of the inside of the body. The MRI scan is used to investigate or diagnose conditions that affect soft tissue, such as: Tumors, including cancer. Soft tissue injuries such as damaged ligaments. Joint injury or disease. !! Compare  PET A positron emission tomography (PET) scan is a type of imaging test. It uses a radioactive substance called a tracer to look for disease in the body. A PET scan shows how organs and tissues are working. PET scans are mainly used to assess cancers, neurological (brain) diseases and cardiovascular (heart-related) disease.  SPECT A SPECT scan is a type of imaging test that uses a radioactive substance and a special camera to create 3D pictures. This test is also known as single-photon emission computerized tomography. While many imaging tests show what the internal organs look like, a SPECT scan can show how well the organs are working. ?? Any Questions Thanks For Attention
