Question 1

A search pattern for viewing radiographs is the ABCs, which stands for:&#10;A) Alignment, bone density, cartilage spaces, soft tissues&#10;B) Anatomy, body mass, connective tissues&#10;C) Alignment, breaks in continuity, cortical margins, soft tissues&#10;D) None of the above

Accepted Answer

The ABCs search pattern for viewing radiographs stands for Alignment, Bone density, Cartilage spaces, and Soft tissues, which helps in systematically evaluating radiographs for abnormalities.

Question 2

Predictor variables help narrow the diagnostic possibilities. If a lesion is wider than it is long and has poorly defined margins, these characteristics are predictive of what kind of lesion?&#10;A) Malignant&#10;B) Metastatic&#10;C) Benign&#10;D) Infectious

Accepted Answer

Lesions that are wider than they are long and have poorly defined margins are often indicative of malignancy. These characteristics suggest aggressive growth patterns and an ability to invade surrounding tissues, which are hallmarks of malignant tumors.

Question 3

Sclerosis is seen on radiograph as _______________ and is a sign of ____________.&#10;A) radiolucent; repair.&#10;B) radiolucent; inflammatory process&#10;C) radiodense; repair&#10;D) radiopaque; repair

Accepted Answer

Sclerosis appears as a radiodense area on a radiograph, indicating increased bone density, which is often a sign of repair or healing in response to stress or injury.

Question 4

Radiologic hallmarks of degenerative joint disease include:&#10;A) Concentric joint space narrowing, sclerotic subchondral bone, and periarticular rarefaction&#10;B) Asymmetrical joint space narrowing, sclerotic subchondral bone, and pseudocysts&#10;C) Osteophyte formation and osteoporosis&#10;D) Asymmetrical joint space narrowing and articular erosions

Accepted Answer

Degenerative joint disease, also known as osteoarthritis, is characterized by asymmetrical joint space narrowing, sclerotic subchondral bone, and the formation of subchondral cysts (often referred to as pseudocysts). These features reflect the wear and tear on the joint, leading to bone remodeling and changes in joint structure.

Question 5

Radiologic hallmarks of rheumatoid arthritis include:&#10;A) Concentric joint space narrowing, erosions of subchondral bone, and periarticular rarefaction&#10;B) Asymmetrical joint space narrowing, sclerotic subchondral bone, and pseudocysts&#10;C) Osteophyte formation and osteoporosis&#10;D) Asymmetrical joint space narrowing and articular erosions

Accepted Answer

Rheumatoid arthritis is characterized by concentric joint space narrowing due to the uniform loss of cartilage, erosions of subchondral bone as a result of the inflammatory process, and periarticular rarefaction (osteopenia) near the joint due to increased bone resorption.

Question 6

Joint capsules become visible on radiograph when they become distended by effusion seen in the instance(s) of:&#10;A) Acute infection&#10;B) Hemophilic bleed&#10;C) Joint trauma&#10;D) All of the above

Accepted Answer

Joint capsules can become distended and visible on radiographs due to effusion, which can be caused by various conditions including acute infection, hemophilic bleed, and joint trauma.

Question 7

If an abnormality discovered on radiograph has characteristics of a malignant lesion, the next step is diagnostic evaluation is:&#10;A) Advanced imaging&#10;B) Surgery&#10;C) Chemotherapy&#10;D) Radiation

Accepted Answer

Advanced imaging is typically the next step in the diagnostic evaluation of a lesion suspected to be malignant based on radiographic characteristics. This can include MRI, CT scans, or PET scans to better define the lesion's extent and characteristics before deciding on treatment options like surgery, chemotherapy, or radiation.

Question 8

Osteoporosis is a metabolic disease that results in decreased total bone mass. What percent of reduction in bone mass must occur before osteoporosis becomes evident on radiographs?&#10;A) 20%&#10;B) 30%&#10;C) 40%&#10;D) 50%

Accepted Answer

The answer of Osteoporosis is a metabolic disease that results...

Question 9

Tumors are generally divided into two categories, based on the amount of bony destruction they incur:&#10;A) Benign and malignant&#10;B) Benign and metastatic&#10;C) Primary and secondary&#10;D) Aggressive and benign

Accepted Answer

Tumors are categorized as benign or malignant based on their growth rate, potential to invade nearby tissues, and ability to spread to other parts of the body. Benign tumors are non-cancerous and typically do not invade surrounding tissues or metastasize, while malignant tumors are cancerous, can invade nearby tissues, and may spread to distant parts of the body.

Question 10

What procedure is necessary to accurately define the infectious organism in an infected joint?&#10;A) MRI with contrast&#10;B) Nuclear imaging with a glucose analog&#10;C) Aspiration biopsy&#10;D) Bone scan

Accepted Answer

Aspiration biopsy is the most direct and accurate method to identify the infectious organism in an infected joint by allowing for culture and sensitivity testing of the synovial fluid.
