Which imaging modality is best for evaluating a suspected rotator cuff tear?Question 60Select one:a.CT scanb.X-rayc.MRId.UltrasoundClear my choice

Break Down the Problem

1. Identify the imaging modalities listed.
2. Understand the specific requirements for evaluating a rotator cuff tear.
3. Analyze the advantages and limitations of each imaging modality.

Relevant Concepts

1. X-ray: Useful for assessing bone structure but not effective for soft tissue evaluation like tendons.
2. CT Scan: Provides detailed images of bone and can evaluate complex structures, but is less effective than MRI for soft tissue.
3. MRI: Excellent for visualizing soft tissues, including muscles and tendons, making it the gold standard for diagnosing rotator cuff tears.
4. Ultrasound: Can be effective for soft tissue assessment and is often used in real-time imaging, but may be operator-dependent.

Analysis and Detail

1. X-ray: Limited in evaluating rotator cuff injuries as it primarily shows bone.
2. CT Scan: While good for looking at joint structures, it still doesn't match the detail of soft tissue seen in MRI.
3. MRI: Provides comprehensive images of the shoulder anatomy, including rotator cuff tendons. It is non-invasive and does not use ionizing radiation, making it safe for repeated use.
4. Ultrasound: Useful in some cases but can miss partial tears or complex conditions and relies on the operator's skill for accurate interpretation.

Verify and Summarize

Upon examining the functionality of each modality, MRI stands out as the best option due to its ability to provide clear images of soft tissues, including the rotator cuff. CT scans and X-rays are less effective for the specific issue of rotator cuff tears, and while ultrasounds can be useful, they are not as dependable.

Final Answer

c. MRI is the best imaging modality for evaluating a suspected rotator cuff tear.
