The electron slows down and changes its direction (this is called “braking” radiation). a Characteristic Radiation b Classical Scatter (Film Fog – low energy – X-ray) c Bremsstrahlung Radiation d Compton Effect (most form of scatter) 8 Also known as radiographic noise, this refers to the random nature in which x-rays interact with the image receptor. If x-rays are produced with just a few photons, the radiographic noise will be higher. A granular or spotty, non-uniformity of the x-ray image results. The use of high MAS, low KVP, and slower image receptors reduce radiographic noise. a Classical Scatter (Film Fog – low energy – X-ray) b Compton Effect (most form of scatter) c Photoelectric Effect d Quantum Mottle 9 Fast screens _______quantum mottle. a increase b decrease c do not change 10 Which of the following is best at visualizing soft tissue changes as seen in a meniscus, disc, or ligament? a CT b MRI c Bone Scan 11 Which of the following uses an injection of radioactive substance to visualize early metastasis to bone? a CT b MRI c Bone Scan 12 Which is used to see the foramen magnum? a Anterior Oblique b Caldwell view c Water’s view d Towne's View 13 Which is used to see the frontal sinus? a Anterior Oblique b Caldwell view c Water’s view d Towne's View 14 Which is seen at the vertebral end plate epiphysis? a Scheuermann’s b Legg Calve Perthes c Sever’s d Erieberg’s 15 Which affects the articular surface of the medial femoral condyle? a Osgood Schlatter’s b Scheuermann’s c Osteochondritis Dessicans d Sever’s 16 Which of the following is AKA pseudospondylolisthesis and is secondary to long standing degenerative arthritis of the lumbar facets and discovertebral joints without a pars separation? a Type IV Traumatic b Type III: Degenerative c Type V Pathologic d Type II Isthmic 17 Which of the following occurs in conjunction with generalized or localized bone disease such as Paget’s or metastasis? a Type IV Traumatic b Type III: Degenerative c Type V Pathologic d Type II Isthmic 18 Which of the following lines of mensuration uses landmarks which fall on a line drawn from the nasion to the center of the sella turcica and one drawn from the basion (anterior foramen magnum) to the center of the sella turcica? a McGregor’s Line b Chamberlain’s Line c Basilar Angle (Martin’s Basilar Angle) d George’s Line 19 Which of the following lines uses as landmarks the posterior body margins? a McGregor’s Line b Chamberlain’s Line c Basilar Angle (Martin’s Basilar Angle) d George’s Line 20 Which of the following is defined as a fracture of the 4th and 5th metacarpal? a Bar Room b Bedroom c Bennett's d Boxer's 21 Which of the following is defined as a fracture of any phalanx of the foot (especially the 1st or 5th digits) and is caused by direct blow? a Bar Room b Bedroom c Bennett's d Boxer's 22 Which is a fracture of the growth plate, metaphysis, and epiphysis a Type 1 b Type II c Type III d Type IV 23 Which is a fracture of the growth plate and metaphysis (most common)? a Type 1 b Type II c Type III d Type IV 24 Which scoliosis type can be postural or compensatory? a Congenital b Structural c Non-structural d Neuromuscular 25 Which scoliosis type is found in cases of polio, cerebral palsy, or muscular dystrophy? a Congenital b Structural c Non-structural d Neuromuscular 26 In which of the following would one see a normal anterior vertebral margin and hypocalcemia? a Blastic Mets b Paget's c Hodgkin's d Lytic Mets 27 In which of the following is there anterior scalloping and a normal bone panel? a Blastic Mets b Paget's c Hodgkin's d Lytic Mets 28 An ivory white vertebra that appears larger than surrounding vertebrae with anterior squaring is suggestive of: a Pagets b Blastic Mets c Hodgkins 29 Select the image of an ivory white vertebra that is most likely due to paget's disease a b c 30 Identify Banhart's fracture a b c d 31 Identify Bar room fracture a b c d 32 Identify teardrop fracture a b c d 33 Identify Pott's fracture a b c d 34 Identify Monteggia fracture a b c d 35 Identify Galeazzi fracture a b c d 36 Identify greenstick fracture a b c d 37 Identify Bennett's fracture a b c d 38 identify chaimberlain's line a b c d 39 identify mcgregors line a b c d 40 identify macrae's line a b c d 41 Identify Macnab's line a b c d 42 Identify Kohler's line a b c d 43 Identify townes view a b c d 44 Identify Water's view a b c d 45 Identify Apical lordotic a b c d 46 Identify PA chest a b c d 47 Identify swimmers a b c d
