1 Agenda CT Contrast Media Weena Swatdiswanee Factorinvolvein contrast enchancement Senior Application Specialist, CT Regional Headquarter Asia Australia Page 1 Page 2 Agenda Contrast Media Definition A medical contrast medium is a substance which is used to improve natural differences in densities between the structures of the human body in medical imaging Factor involvein contrast enchancement Contrast media makes the image more assessable Page 3 Page 4 Agenda Factor involvein contrast enchancement Page 5 Page 6 Handzettel 1
2 Agenda What kind of contrast media that we use in CT? Factor involvein contrast enchancement Radiolucent Negative / Neutral contrast agent Absorb less x-ray Appear dark on the image Air /CO 2 Radiopaque Positive contrast agent Absorb more x-ray Appear white on the image Iodine, Barium, Gastrograpfin Page 7 Page 8 What kind of contrast media that we use in CT? What kind of contrast media that we use in CT? Positive contrast media Positive contrast media Page 9 Page 10 What kind of contrast media that we use in CT? What kind of contrast media that we use in CT? Negative/ Neutral contrast media Page 11 Page 12 Handzettel 2
3 CT image with contrast media What kind of contrast media that we use in CT? Contrast medium: Categories Differences in iodinated contrast medium: Monomeric Dimeric Ionic Non Ionic Low Osmolar Contrast Medium High Osmolar Contrast Medium Iso-Osmolar Contrast Medium Page 13 Page 14 Contrast medium: Structure I Contrast medium: Chemistry Page 15 Page 16 Contrast medium: Chemistry Contrast medium: Reactions I Page 17 Page 18 Handzettel 3
4 Agenda Factor involvein contrast enchancement What do you HAVE TO CHECK to avoid patients damage? Prevention is always better Ask for any allergies Check if the patient takes Metformin (diabetics= Lactic acidosis) Check the blood value of kidneys Creatinin ( max.1.5) egfr* ( >60) ( new 45) *Estimated Glomerular Filtration Rate Page 19 Page 20 Agenda What to do in an Emergency? Factor involvein contrast enchancement Call your Emergency unit! Medication Cortisone ( Prednisolon) H1,H2 ( Antihistamine e.g.fenistill, Tagamed) Oxygen i.v. fluid ( NaCl) Page 21 Page 22 Agenda Factors involved in Contrast Enhancement SOMATOM Scope Factor involvein contrast enchancement SOMATOM Force Page 23 Page 24 Handzettel 4
5 Factors involved in Contrast Enhancement Patient size Size matter! Cardiac Output Age Page 25 Page 26 Cardiac Output Factors involved in Contrast Enhancement: kv setting SOMATOM Scope SOMATOM Force Page 27 Page 28 Factors involved in Contrast Enhancement: kv setting Factors involved in Contrast Enhancement: kv setting Relation between kv and CM enhancement Relation between kv and CM enhancement Page 29 Page 30 Handzettel 5
6 Factors involved in Contrast Enhancement: CM Volume Volume Injection time Saline Tubing Injection Rate Concentration Needle Temperature Page 31 Page 32 Injection Time Injection Time Page 33 Page 34 Time of Injection Injection rate Page 35 Page 36 Handzettel 6
7 Injection rate Flow Rate issue High Flow rate - Abdomen scan for all indication specially for GI Bleeding Liver Tumor Characterization Pancreatic Carcinoma No need high flow rate if you are interested in late portal phase only Page 37 Page 38 Concentration Concentration Higher Concentration à Higher Viscosity Contrast warm up is Mandatory Page 39 Page 40 Flush Flush Pushes contrast in tubing and peripheral veins into central veins Allows reduction in contrast volume Increase peak attenuation Reduced streak artifacts from veins and right heart Simpler to implement with dual head injector Page 41 Page 42 Handzettel 7
8 Needle Needle For CT Angiography We recommend using the largest gauge needle possible Site: Cubital or Ante-Cubital Fossa Large vein, low impedance = Higher flow rates Closer to heart = More contrast in circulation, less in arm Page 43 Page 44 Tubing Tubing We recommend using the tubing with the widest internal lumen Thin tuning lumen = Increased pressure = low flow rate Injector set rate Flow is reliant on other factors. Page 45 Page 46 Temperature Temperature The temperature of the contrast greatly affects the viscosity of the contrast media. This is not linear: Concentration Temperature 18 C 21 C 37 C 300 mg Body Temp is 5x lower viscousity as 400 mg Room Temp 300 mg Body Temp is 2x less viscousity as 400 mg Body Temp 400 mgi/dl mgi/dl mgi/dl Page 47 Page 48 Handzettel 8
9 Temperature Agenda Don t leave the bottle out on the bench while waiting to perform the study: In 1 hr the temperature drops by half Factorinvolvein contrast enchancement Page 49 Page 50 Contrast Access Access Big questions Cubital vien Pedal vien How much contrast do we need? What is the proper timing to get good image quality? Page 51 Page 53 How much contrast do we need? Big questions Should I go by body weight? How much contrast do we need? What is the proper timing to get good image quality? Page 54 Page 55 Handzettel 9

Arnold Schwarzenegger has BMI of 33 Danny DeVito has a BMI of 33.5 Vascular region ( CT Angio) with multi slice CT (>64 slice ) can reduce amount of contrast from 100 cc to cc follow by saline flush CTA Head & Neck CTA Whole Aorta CTA Extremity CT Coronary CT PE Venous return region BMI can be useful Body : small size patient cc / standard to big size 100 cc Page 56 Page 57 Big questions Manual How much contrast do we need?
