Case 1-normal MSK imaging
This case will demonstrate the normal appearance of various parts of the musculoskeletal system on different types of imaging. We will start with the hand, since it is involved in many rheumatologic disorders.
Question 1:
a) What is the commonest first imaging performed on patients with MSK complaints, overall?
Radiography, which is readily available, quick, cheap, with low radiation dose, is often the first imaging performed for patients with MSK complaints.
b) What other types of imaging could be considered for MSK complaints?
Other types of imaging include ultrasound, CT, MR and nuclear medicine. Contrast can also be introduced into a joint space (arthrography) prior to CT or MR to give more detailed examination of the intra-articular features of a joint. Depending on the clinical question and the joint involved, any of these modalities could be considered. To help in deciding what is appropriate, there is an online resource available to all from the American College of Radiology that lists recommendations based on clinical presentation.
