Objectives: After studying the article titled “Utility of High-Resolution Sonography for Evaluation of Knee Joint Pathologies as a Screening Tool,” you will be able to:
Compare high-resolution sonography (HRS) in the evaluation of knee pathology with magnetic resonance imaging (MRI)
Review the imaging protocols and terminology for HRS of the knee
List the imaging benefits and limitations of HRS knee pathology as a screening option
In Figure 5, MRI and HRS images suggest a tear of the: Anterior cruciate ligament Posterior collateral ligament Lateral collateral ligament Medial collateral ligament
What was a limitation of this study? Large sample size Lack of equipment Small sample size Patient claustrophobia
HRS depicted what percent accuracy in the detection of Baker’s Cyst? 98% 99% 94% 93%
The average age for the majority of the patients enrolled in this study was: 21–30 years of age 31–40 years of age 41–50 years of age 51–60 years of age
For evaluation of the anterior aspect of the knee with HRS, the patient was placed in the supine position and the knee flexed approximately: 30–45 degrees 15–20 degrees 45–60 degrees 20–30 degrees
Figure 1 depicts an HRS image of the knee, demonstrating a hypoechoic collection in the joint space correlated with MRI images, suggesting: Baker’s cyst Joint effusion Meniscal tear Osteophyte collection
MRI is considered the gold standard imaging technique for assessing knee joint pathologies because it _____. Is inexpensive Uses little radiation Has multiplanar capabilities Is widely available
