0.3 and 1.5 Tesla Mri

Sometimes, if my daily agenda allows to spread my curiosity (time is never enough!), I make a comparison between 0.3 and 1.5 Tesla Mri imaging studying the same patient.

These are the pictures of a sprained medial collateral ligament of a professional football player, quite similar to what is shown in my recent post medial collateral ligament tear.

I always complete my study with a dynamic ultrasound exam; in this patient the presence of a calcification is noted, not visible on Mri scans.

Medial Collateral Ligament Tear

This is the case of a professional football player with a  grade 2 injury of the medial collateral ligament; high signal and partial disruption of the ligament is seen on Mri exam. The study is completed by dynamic ultrasound and elastosonography evaluation;  in this picture the elastosonography signal works like a “contrast agent”, with the red color that depicts the real extent of the ligament tear.

Have you ever tried to change the point of view of your ultrasound images? Takea look at the picture below, in which both Mri and ultrasound images have the same angle orientation.
