    3. RADIOLOGY AND DIAGNOSTIC IMAGING 1st Lecture

    4. DIAGNOSTIC IMAGING • Plain X ray • Myelography • CT scan • MRI scan • Ultrasound • Isotope Study e.g. Bone scan • Angiogram

    5. Plain x ray CT Ultrasonography

    6. CT MRI Myelography

    7. Ultrasonography Bone scan

    8. Radiology & Diagnostic Imaging Overview • X-Rays • High-energy electromagnetic waves • Travel in straight lines • Shorter wave length than visible light • Able to penetrate solid materials of varying densities • Capable of exposing a photographic plate (x-ray film) • Much the same way as a camera exposes film

    9. Radiology & Diagnostic Imaging Overview (continued) • X-Rays (continued) • Used to visualize internal organs and structures of body • Provide valuable means for verifying presence of illness or disease • Radiology • Study of the diagnostic and therapeutic uses of x-rays

    10. Radiology & Diagnostic Imaging Overview (continued) • X-Rays (continued) • Used to visualize internal organs and structures of body • Provide valuable means for verifying presence of illness or disease • Radiology • Study of the diagnostic and therapeutic uses of x-rays

    11. PROCEDURES AND TECHNIQUES RADIOLOGY AND DIAGNOSTIC IMAGING

    12. Angiocardiography(Cardiac Catheterization) • Pronounced • (an-jee-oh-kar-dee-OG-rah-fee) • (CAR-dee-akkath-eh-ter-ih-ZAY-shun) • Defined • A specialized diagnostic procedure in which a catheter is introduced into a large vein or artery, usually of an arm or a leg, and is then threaded through the circulatory system to the heart

    13. Angiocardiography

    14. Angiography • Pronounced • (an-jee-OG-rah-fee) • Defined • A series of x-ray films allowing visualization of internal structures after the introduction of a radiopaque substance

    15. Coronary angiography MRI angiography

    16. Cerebral Angiography • Pronounced • (seh-REE-bral an-jee-OG-rah-fee) • (SER-eh-bral an-jee-OG-rah-fee) • Defined • Injection of a radiopaque contrast medium into an arterial blood vessel (carotid, femoral, or brachial) to make visualization of the cerebral vascular system via x-ray possible

    17. Cerebral Angiography

    18. Renal Angiography • Pronounced • (REE-nal an-jee-OG-rah-fee) • Defined • X-ray visualization of the internal anatomy of the renal blood vessels (blood vessels of the kidney) after injection of a contrast medium

    19. Renal angiography

    20. Arteriography • Pronounced • (ar-tee-ree-OG-rah-fee) • Defined • X-ray visualization of arteries following the introduction of a radiopaque contrast medium into the blood stream through a specific vessel by way of a catheter

    21. Hepatic arteriography

    22. Arthrography • Pronounced • (ar-THROG-rah-fee) • Defined • The process of taking x-rays of the inside of a joint, after a contrast medium has been injected into the joint • Contrast medium makes the inside of the joint visible

    23. Arthrography

    24. Barium Enema (BE) • Pronounced • (BAH-ree-um EN-eh-mah) • Defined • Infusion of a radiopaque contrast medium, barium sulfate, into the rectum • Contrast medium is retained in lower intestinal tract while x-ray films are obtained of the lower GI tract

    25. Barium Enema (BE)

    26. Barium Swallow(Upper GI Series) • Pronounced • (BAH-ree-um SWALL-oh) • Defined • Oral administration of a radiopaque contrast medium, barium sulfate, which flows into the esophagus as the person swallows • X-rays are taken as barium sulfate flows into the upper GI tract

    27. Bronchography • Pronounced • (brong-KOG-rah-fee) • Defined • Bronchial examination via x-ray following the coating of the bronchi with a radiopaque substance

    28. Bronchography Main air way ronchgraphy

    29. Cholangiography(Intravenous) • Pronounced • (koh-lan-jee-OG-rah-fee) • (in-trah-VEE-nus) • Defined • Visualizing and outlining of the major bile ducts following an intravenous injection of a contrast medium

    30. Cholangiography

    31. Cholangiography(Percutaneous Transhepatic) • Pronounced • (koh-lan-jee-OG-rah-fee) • (per-kyoo-TAY-nee-us trans-heh-PAT-ik) • Defined • Examination of the bile duct structure using a needle to pass directly into an intrahepatic bile duct to inject a contrast medium • Also known as PTC or PTHC

    32. Percutaneou cholangiography

    33. Cholangiopancreatography(Endoscopic Retrograde) • Pronounced • (koh-lan-jee-oh-pan-kree-ah-TOG-rah-fee) • (en-doh-SKOP-ic RET-roh-grayd) • Defined • Procedure that examines the size of and the filling of the pancreatic and biliary ducts through direct radiographic visualization with a fiberoptic endoscope

    34. Endoscopic Retrograde

    35. Cholecystography(Oral) • Pronounced • (koh-lee-sis-TOG-rah-fee) • Defined • Visualization of the gallbladder through x-ray following the oral ingestion of pills containing a radiopaque iodinated dye

    36. Cholecystography

    37. Cineradiography • (Pronounced) • (sin-eh-ray-dee-OG-rah-fee) • Defined • Diagnostic technique combining the techniques of fluoroscopy, radiography, and cinematography by filming the images that develop on a fluorescent screen with a movie camera

    38. Cineradiography

    39. Computed Axial Tomography (CT, CAT) • Pronounced • (kom-PEW-ted AK-see-al toh-MOG-rah-fee) • Defined • A painless, noninvasive diagnostic x-ray procedure using ionizing radiation that produces a cross-sectional image of the body
