Recall the most common radiologic exams to be utilized with sonography in the evaluation of soft tissue lesions.
Classify soft tissue sarcomas and soft tissue masses identifiable with ultrasound.
Recognize if ultrasound or MRI would be the best examination choice for the evaluation of soft tissue masses.
Deep soft tissue masses usually measure more than _____ when identified by ultrasound. A. 4 cm B. 6 cm C. 10 cm D. 15 cm
Why would MRI be the study of choice to localize and stage a soft tissue mass? A. The diagnostic accuracy of sonography is better for delineating soft tissue masses from proximal vascular bodies. B. MRI more accurately delineates surrounding soft tissue structures and their closeness to neurovascular structures. C. MRI is most helpful in evaluating lesions superficial to the deep fascia. D. Sonography is more reliable for deeper masses in large anatomical regions.
Rim enhancement, observed in gadolinium-enhanced MRI studies, is an image descriptive term that helps radiologists differentiate between which of the following? A. Vascular and non-vascular tumors B. Fluid-filled and fatty tissues C. Sarcomas and edema D. Solid and cystic lesions
The most common soft tissue masses are _________. A. Endometriomas B. Cystic echinococcosis C. Lipomas D. Schwannomas
Soft tissue sarcomas represent less than 1% of cancers in the US. Which one of the following is an example more commonly found in teens or young adults? A. Rhabdomyosarcoma B. Leiomyosarcoma C. Undifferentiated pleomorphic sarcoma D. Liposarcoma
__________ are mostly solitary masses commonly affecting the small peripheral nerves in the head, neck, and extremities. A. Rhabdomyosarcomas B. Lipomas C. Schwannomas D. Leiomyosarcomas
In the differentiation between cystic and solid components of structures, one advantage of ultrasound over CT and MRI could be which of the following? A. Delineating deep tissue or nerve structures B. Repositioning patients C. Injecting contrast agents D. Determining anatomical relationships of masses
