Diagnostic medical sonographer, cardiovascular sonography technologist is also known as a diagnostic imaging specialist. A career in allied healthcare can be confusing, especially when you have to decide between Diagnostic Medical Sonography and Cardiovascular Sonography.   

Both diagnostic medical sonography and cardiovascular sonography are regulated medical professions by the College of Medical Radiation and Imaging Technologists of Ontario (CMRITO).  

How Sonography Works?  

Sonogram and ultrasound are usually used interchangeably. Ultrasound is a tool used to take a picture, and a sonogram is the end result of the process. Sonography is a non-invasive, painless procedure. It uses high-frequency sound waves to produce images of soft tissues, blood vessels, and organs from inside the body.  

Duties of Diagnostic Medical Sonographer and Cardiovascular Sonography Technologist  

  • Prepare patients for procedures   
  • Maintain diagnostic imaging equipment  
  • Efficiently operate equipment to obtain diagnostic images  
  • Ensure adequate coverage of body areas needed for diagnoses and check for the quality of images  
  • Identify diagnostic information and recognize abnormalities   
  • Analyze diagnostic information and provide a summary to physicians  
  • Record finding and keep track of patient’s records.  

Diagnostic Medical Sonographer

  • Echocardiographers or Cardiac sonographers specialize in imaging a patient’s heart. They work closely with physicians or surgeons before, during, and after procedures. Cardiac sonographers may have to take echocardiograms of fetal organs during pregnancy so that physicians can diagnose cardiac conditions.  
  • Vascular sonographers create images of blood vessels and collect data that help diagnose disorders affecting blood flow. They often measure a patient’s blood pressure and the volume of blood in their arms, legs, fingers, and toes and identify blocked arteries or blood clots in the body.
