What is Medical Sonography?
What is Medical Sonography?
Diagnostic Medical Sonography is a non-invasive and painless medical test that uses sound waves to create images of blood flow, organs, and tissues to assist doctors in confirming or ruling out a specific diagnosis. Also known as ultrasound, sonography is a common tool used by doctors in obstetrics and gynecology (OB-GYN) to monitor a woman’s pregnancy.

Brain Foods
Brain Foods
Back in the day (whenever that was) it was common to think that foods shaped like particular organs or body parts would help keep the actual corresponding body part healthy and well.

As scientific thought began to work its way to the forefront, those ideas were treated like wives’ tales or folklore. So, in today's world we can rely on science to point the way towards foods that contribute to optimal cognitive function and we no longer have to spend our time foraging for mini

MRI Gets to the Bottom of Smell, Taste Dysfunction from COVID-19

A study conducted by a team of researchers from the U.S. National Institutes of Health found brain damage in patients who died of COVID-19.

The 25-year-old female patient had been diagnosed with COVID-19, with symptoms including anosmia (loss of smell) and ageusia (loss of taste). Experience with her case was reported by Dr. Khaled Gad, PhD, and Ismail Ibrahi

The job outlook for Physical Therapist Assistants and the demand for their services is so good that government analysts predict more than 1,000 positions will open up every month, on average, for the next decade.

Trained and licensed Physical Therapist Assistants should have little trouble finding job opportunities for the foreseeable future.

There is a high demand for physical therapist assistants, especially due to the aging baby boomers who are more susceptible to chron
Blind Test Shows AI-Enhanced MRI Scans
Blind Test Shows AI-Enhanced MRI Scans
If you have ever had an MRI scan before, you’ll know how unsettling the experience can be. You’re placed in a claustrophobia-inducing tube and asked to stay completely still for up to an hour while unseen hardware whirs, creaks, and thumps around you like a medical poltergeist. New research, though, suggests AI can help with this predicament by making MRI scans four times faster, getting patients in and out of the tube quicker.

Diagnostic Medical Sonography (DMS) Degree Program

What Is Diagnostic Medical Sonography?

Diagnostic medical sonography (DMS) — also sometimes referred to as ultrasound or diagnostic imaging — is the process of operating specialized medical equipment that uses high-frequency sound waves to create images of the body’s organs and tissues.

They work in concert with physicians and the broader health care team to assess a patient’s symptoms and ultimately develop a medical diagnosis. They’re often in charge of everything from preparing and maintaining equipment, prepping patients for the procedure, and answering any questions.

Also, they review the ultrasound images to check for quality and coverage of the areas needed, analyzing information to provide physicians with an overview of their findings, and recording all their findings for patients’ medical records.

It’s an area that is fast-growing in healthcare and increasingly used for the detection of a wide range of conditions, including heart disease, heart attack, and vascular disease.

Ultrasound can be utilized for examinations throughout the body, and sonographers can specialize in areas like abdominal (including nearby organs like the kidney, liver, gallbladder, pancreas, or spleen); breasts; cardiac; musculoskeletal (i.e., muscles, ligaments, tendons, joints); pediatrics; obstetrics and gynecologic; and vascular (i.e., arteries, vessels, and blood flow).

How Do You Become a Diagnostic Medical Sonographer?

Becoming a diagnostic medical sonographer generally requires a formal education — most often an associate degree from a qualified, accredited school — and often professional certification.

Ideally, you’ll want a program like the one we offer at Casa Loma College, which combines in-depth classroom coursework in medical concepts and terminology with hands-on, clinical experience.

A Diagnostic Medical Sonography associate degree program will prepare you to complete the certification exams that will help you in your future job search. For example, upon successful completion of our DMS program, Casa Loma graduates are eligible to apply for national certification examinations of the American Registry of Diagnostic Medical Sonographers (ARDMS) in the areas of Abdomen, Obstetrics and Gynecology and Sonography Principles* and the American Registry of Radiologic Technologists (ARRT) in the Sonography Primary Pathway Certification. **

What Will You Learn in Diagnostic Medical Sonographer Classes?

At Casa Loma College, our Associate of Science degree in Diagnostic Medical Sonography is a seven-semester program that combines classroom instruction with practical experience in labs and clinical work in a wide variety of healthcare settings. It’s a blended learning program, so while some of your coursework is completed online, you also get the benefit of hands-on training with experienced professionals.

Topics covered in our diagnostic medical sonography classes include:

  • Human anatomy and physiology
  • Medical terminology
  • Fundamentals of sonography
  • Abdominal and small parts imaging
  • Obstetrics and gynecology imaging
  • Professional aspects of sonography
  • Vascular imaging
  • Patient/sonographer interactions
  • Physical principles and instrumentation of imaging

What’s the Outlook for Diagnostic Medical Sonographer Careers?

According to the Bureau of Labor Statistics, employment of diagnostic medical sonographers is expected to grow 17 percent through 2029. That’s over four times the average for all occupations. Most of these will probably be employed at imaging centers and state, local, or private hospitals, which employed 61% of all sonographers in 2019.

With the large baby boomer generation aging, the demand for health care services — including the need to be able to diagnose conditions such as heart disease and liver disease — is increasing. This means that diagnostic medical sonographers are on track to remain very in-demand.
