3D Medical Animation of a Knee Replacement


OMG....Extraoccular Muscle Entrapment

Extraoccular Muscle Entrapment: This patient fell, sustaining orbital floor fracture of left eye.
The inferior rectus muscle has become stuck in the fracture, preventing the patient from being able to look directly downward.
This is evident in the picture below. The diffuse scleral redness is due to traumatic subconjunctival hemorrhage.

more targeted therapy for psoriatic and rheumatoid arthritis by contrast-enhanced MRI

In the past the treatment for patients with psoriatic arthritis was based on the treatment for those with rheumatoid arthritis
According to a new study ,contrast-enhanced magnetic resonance imaging (MRI) could help to differentiate between psoriatic and rheumatoid arthritis in hands and wrists. the results of the study might lead to a more targeted therapy unique to each condition.

This study
that was done at the University Hospital of Tubingen imaged using contrast-enhanced magnetic resonance imaging 31 patients with rheumatoid arthritis and 14 with psoriatic arthritis. The contrast media in rheumatoid and psoriatic arthritis is presumed to be different and the difference can only be seen 15 minutes after the contrast material is given.
“Our study revealed a significant difference in perfusion between those patients with rheumatoid arthritis and psoriatic arthritis after 15 minutes. However, since it was a small group of patients and there was an overlap in perfusion values between both types of arthritis, a diagnosis could not be led by contrast-enhanced MRI alone. Our results are nonetheless promising though,” said Nina Schwenzer, lead author of the study.
