Why I love to teach
As a technical director and team lead sonographer at North York General Hospital and the devoted co-founder of MTIMA, a non-profit organization addressing Malawi’s inequity in cardiac health care, I am committed to enhancing sonography education and standards. My work focuses on supporting global health services and applying my knowledge in health informatics to connect and improve healthcare.

Echocardiography pearl: using strain imaging in cardiac oncology
You can apply strain imaging echocardiography to assess if your cancer patient is suffering from cardiotoxicity induced by chemotherapeutic agents. If the global longitudinal strain (GLS) values increase above a certain level, it’s high time you let the oncologist in charge know.
Analyzing ventricular dysfunction with the help of strain imaging echocardiography
How do you recognize myocardial infarction or heart valve disease using strain imaging echocardiography? You have to take a good look at the strain graph and the bull’s-eye plot. There’s even a way to assess hypertrophy of the left ventricle with this ultrasound modality.
Interpreting the bull's-eye plot in speckle tracking echocardiography
The bull’s-eye plot, much like the strain graph, is a visualized version of data collected from strain imaging echocardiography. It gives you information on how well segments of the left ventricle wall contract. The contractility is depicted both as colors and global longitudinal strain (GLS) values.
What is tissue Doppler and speckle tracking in echocardiography?
Tissue Doppler imaging and speckle tracking, also called strain imaging, are both ultrasound modalities used to assess left ventricle myocardial function. Speckle tracking has only gained popularity recently and not everyone knows how it works.
