Rad Tech Detective
100
A disease whose underlying cause is unknown is described by this term.
What is idiopathic?
100
This imaging modality uses a magnetic field and radiofrequency energy rather than ionizing radiation.
What is magnetic resonance imaging, or MRI?
100
This condition is defined by the presence of air in the pleural cavity.
What is a pneumothorax?
100
This fibrous membrane covers the outer surfaces of bone.
What is the periosteum?
100
A patient has sudden, severe pain at the first metatarsophalangeal joint. Increased uric acid and urate crystal deposition are the key clues to this metabolic disorder.
What is gout?
200
This is the initial response of body tissues to a local injury.
What is inflammation?
200
On ultrasound, a fluid-filled structure that transmits sound easily and appears dark is described by this term.
What is anechoic?
200
Unlike air in the pleural cavity, infected fluid within the pleural cavity is called this.
What is empyema?
200
This common form of degenerative arthritis is associated with osteophyte development.
What is osteoarthritis?
200
A young patient has repeated fractures after relatively minor trauma. The evidence includes an inherited connective-tissue disorder, decreased bone density, and thin cortices.
What is osteogenesis imperfecta?
300
This term means an increase in the number of cells, rather than an increase in the size of individual cells.
What is hyperplasia?
300
This CT measurement describes the attenuation of a particular tissue relative to water.
What is the CT number?
300
This hereditary disease produces abnormal mucus that obstructs the airways.
What is cystic fibrosis?
300
After a fall onto an outstretched hand, a distal radius fracture shows posterior displacement of the distal fragment. This is the named fracture.
What is a Colles fracture?
300
Increased lung volume, flattened diaphragms, and increased retrosternal airspace.
What is emphysema?
400
A malignant tumor originating from connective tissue is called this.
What is a sarcoma?
400
In nuclear medicine, this device detects the radiation emitted from the patient.
What is a gamma camera?
400
This mycobacterial disease can produce apical lung lesions or cavities that may calcify.
What is tuberculosis?
400
Multiple punched-out osteolytic lesions scattered throughout the skeletal system suggest this disease.
What is multiple myeloma?
400
A patient develops bone pain after infection or trauma. Infection extends through the medullary cavity and lifts the periosteum; later imaging can show bone destruction and periosteal reaction.
What is osteomyelitis?
500
Hypotension, vascular collapse, urticaria, bronchospasm, and laryngeal edema are characteristic of this reaction.
What is an anaphylactic reaction?
500
Name these two MRI techniques in order: the first evaluates movement of water molecules within tissues; the second evaluates blood flow through tissues.
What are diffusion imaging and perfusion imaging?
500
An endotracheal tube is advanced too far into the right mainstem bronchus. This complication can develop in the left lung.
What is left lung atelectasis?
500
This condition is a cleft in the pars interarticularis, situated between the superior and inferior articular processes of a vertebra.
What is spondylolysis?
500
A clot from a deep vein of the lower extremity travels through the venous circulation and right heart.
What is a pulmonary embolism?
