CAMRT General Preparation Guide

The CAMRT National Certification Examination in Radiological Technology is the Canadian entry-to-practice exam for the RTR credential, administered by CAMRT and delivered by Yardstick. It has 185 single-best-answer multiple-choice questions and a four-hour time limit, taken at an approved Test Centre or by remote proctoring. The Clinical Expert role dominates the blueprint at roughly 70-85% of questions (performing diagnostic procedures and administering substances 27-32%; analyzing image and data quality 27-32%; safe work and managing imaging systems 14-24%), with the remaining 15-30% spread across the Professional, Communicator, Collaborator, Care Provider, Leader and Scholarly Practitioner roles. The exam fee is $980 CAD per sitting plus a Yardstick seat fee, and there is no fixed pass mark - the Exam Validation Committee sets the standard using a modified Angoff method. This 130-question bank provides original practice weighted to the May 2024 blueprint.

Sample CAMRT RTR Exam Practice Questions

Try these sample questions to review concepts for the CAMRT RTR Exam exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 130+ question experience with AI tutoring.

1For a routine PA chest radiograph on an ambulatory adult, which positioning instruction best demonstrates the lungs to their full extent and moves the scapulae out of the lung fields?
A.Roll the shoulders forward and rest the backs of the hands on the hips
B.Raise both arms fully overhead and clasp the hands
C.Place the hands on top of the head and extend the neck
D.Cross the arms tightly across the front of the chest
Explanation: Rolling the shoulders anteriorly and placing the backs of the hands on the hips rotates the scapulae laterally off the lungs. Exposure is made on the second full inspiration to maximise lung volume and depress the diaphragm.
2A PA chest radiograph is performed at a 180 cm (72 inch) source-to-image distance rather than the typical 100 cm used for many other examinations. The main reason for the longer SID is to:
A.Increase magnification of the heart for assessment
B.Reduce magnification so heart size is represented accurately
C.Increase the entrance skin dose to the patient
D.Allow a lower kVp to be used
Explanation: A 180 cm SID minimises magnification and geometric unsharpness of the heart, allowing accurate assessment of the cardiothoracic ratio. The longer distance also improves recorded detail of the lungs.
3To demonstrate a small pleural effusion that may be missed on an erect PA chest, which projection allows fluid to layer along the dependent lateral chest wall?
A.AP axial (lordotic) projection
B.Lateral decubitus with the affected side down
C.Lateral decubitus with the affected side up
D.Anterior oblique projection
Explanation: A lateral decubitus with the affected side down lets free pleural fluid gravitate to and layer along the dependent lateral chest wall, where even small effusions become visible with a horizontal beam.
4For an AP axial projection of the cervical spine, the central ray is directed 15-20 degrees cephalad primarily to:
A.Superimpose the mandible over the upper cervical bodies
B.Open the intervertebral disc spaces by projecting through them
C.Demonstrate the C1-C2 region through the open mouth
D.Reduce magnification of the lower cervical spine
Explanation: Angling the central ray 15-20 degrees cephalad aligns the beam with the intervertebral disc spaces and projects the mandible upward, opening the lower cervical disc spaces (typically C3-C7) for evaluation.
5Which projection of the cervical spine best demonstrates the intervertebral foramina, and which way must the patient be rotated to show them?
A.AP open mouth projection with no patient rotation
B.Anterior oblique; the side farthest away from the image receptor is shown
C.Posterior oblique; the side farthest from the image receptor is shown
D.Lateral projection with no patient rotation
Explanation: Oblique cervical projections demonstrate the intervertebral foramina. On a posterior oblique (patient rotated 45 degrees toward the tube), the foramina farthest from the image receptor (upside) are shown; on an anterior oblique the foramina closest to the receptor (downside) are shown.
6On a lateral projection of the lumbar spine, which technical step most directly reduces image-degrading scattered radiation and helps keep the vertebral bodies aligned with the long axis of the image receptor?
A.Close collimation with a radiolucent support placed under the waist
B.Removing the antiscatter grid so that the patient dose is lower
C.Increasing the source-to-image distance to 180 cm as for a chest
D.Suspending respiration on the second full inspiration
Explanation: Close collimation reduces the volume of tissue irradiated and therefore the scatter reaching the receptor, while a radiolucent support under the waist keeps the spine parallel to the receptor so the vertebral bodies are not distorted.
7A clinician requests imaging of the pars interarticularis to assess for spondylolysis. Which lumbar spine projection best demonstrates the pars interarticularis and produces the classic 'Scotty dog' appearance?
A.AP projection
B.Lateral projection
C.45-degree oblique projection
D.AP axial L5-S1 projection
Explanation: A 45-degree oblique lumbar spine projection demonstrates the zygapophyseal joints and the pars interarticularis, forming the 'Scotty dog' image. A defect in the dog's neck (the pars) indicates spondylolysis.
8For a PA projection of the wrist to evaluate a suspected scaphoid fracture, which additional manoeuvre is commonly added to elongate the scaphoid and reduce foreshortening?
A.Flexion of the wrist
B.Ulnar deviation of the wrist
C.Radial deviation of the wrist
D.Full pronation with the fingers flexed
Explanation: Ulnar deviation (the hand turned toward the ulnar/little-finger side) moves the scaphoid into a more longitudinal position and reduces its normal foreshortening, separating it from adjacent carpals so a fracture is easier to detect.
9Which positioning produces a true lateral elbow with the radial head, capitulum and a well-demonstrated fat pad sign useful for detecting occult fractures?
A.Elbow flexed 90 degrees, humerus and forearm in one plane, hand lateral
B.Elbow fully extended, humerus and forearm flat, with the hand supinated
C.Elbow flexed 45 degrees with the forearm raised and the hand pronated
D.Elbow flexed 90 degrees but with the hand and forearm fully pronated
Explanation: A true lateral elbow requires 90 degrees of flexion with the humerus and forearm on the same plane and the hand in a true lateral (thumb-up) position. This superimposes the epicondyles and demonstrates the anterior and posterior fat pads, which become displaced when an effusion or fracture is present.
10For an AP projection of the shoulder to demonstrate the greater tubercle in profile laterally, the arm should be placed in:
A.Internal rotation
B.External rotation
C.Neutral rotation
D.Full abduction overhead
Explanation: External rotation of the humerus (epicondyles parallel to the receptor) places the greater tubercle in profile on the lateral aspect and shows the humerus in a true AP. Internal rotation gives a lateral humerus and profiles the lesser tubercle medially.

About the CAMRT RTR Exam Exam

The CAMRT National Certification Examination in Radiological Technology is the entry-to-practice exam that allows graduates to use the RTR credential and seek registration with a provincial regulator (outside Quebec, which administers its own OTIMROEPMQ exam). It contains 185 single-best-answer multiple-choice questions answered in four hours on a computer, delivered by Yardstick in a hybrid model that lets candidates write at an approved Canadian Test Centre or under remote proctoring. The exam is competency-based: a minimum of 80% of questions assess application and critical thinking, and a maximum of 20% are knowledge recall. Content follows the May 2024 blueprint structured around the CanMEDS-MRT roles, with the Clinical Expert role accounting for roughly 70-85% of the exam, including radiographic positioning, exposure and image production, radiation safety, contrast and pharmaceutical administration, and image-quality analysis. The passing score is set by an Exam Validation Committee using a modified Angoff method rather than a fixed percentage.

CAMRT RTR Exam: Suggested Study Strategy

1Build your study plan around the May 2024 Radiological Technology blueprint and competency profile, and spend the most time on the two largest categories - performing diagnostic procedures and analyzing image and data quality.
2Because at least 80% of questions test application and critical thinking, practise reasoning through clinical scenarios rather than memorising isolated facts; ask what you would do for this patient and this image.
3Master exposure relationships cold: the 15% kVp rule, the mAs reciprocity and inverse square law, grid ratios and clean-up, and what AEC controls and does not control, then apply them to optimisation questions.
4Use the secondary weightings as a guide - respiratory and skeletal procedures and pathologies are weighted High, so prioritise chest, fracture and extremity positioning and recognition over low-weighted modalities.
5Buy the official CAMRT practice exam ($75 for 100 sample questions and three attempts) to learn the Yardstick platform, on-screen timing and the single-best-answer style before exam day.
6Drill contrast and patient-safety content: iodinated versus barium indications and contraindications, eGFR and metformin considerations, signs of an anaphylactoid reaction, and ALARA and shielding practice.
