High-Yield Radiology Technician Syllabus Breakdown
The exam is designed to be a comprehensive assessment of a technician’s duties. A strategic plan allocates the most time to the most heavily weighted domains.
| Exam Domain | High-Yield Topics and Key Concepts for 2025 |
|---|---|
| Radiographic Procedures & Patient Positioning | ~40-50%: This is the most significant domain. It covers all standard and special projections for the axial skeleton (skull, facial bones, spine) and appendicular skeleton (upper/lower extremities, shoulder/pelvic girdles). You must know patient/part positioning, CR angulation, collimation, breathing instructions, and the specific anatomy that should be visualized on a perfect image. Chest and abdomen radiography are also included. |
| Image Production & Evaluation | ~20-25%: This domain covers the science behind the image. Exposure Factors: The relationship between kVp (contrast, penetration), mAs (density, quantity), and SID (intensity, detail). Image Quality: Spatial resolution (detail), distortion (magnification, elongation), and radiographic noise. Image Receptors: Principles of digital radiography (DR) and computed radiography (CR). Grids: Purpose, grid ratio, and grid errors. Image Critique: This is a huge component. You will be asked to identify errors on images and state the corrective action. |
| Radiation Protection (ALARA) | ~15-20%: This is a theme woven throughout the entire exam. Cardinal Principles: Time, distance, shielding. Patient Protection: Gonadal shielding, collimation, communication, and choosing appropriate technical factors. Personnel Protection: Dosimeters (TLDs, OSLs), lead aprons, and safe practices during fluoroscopy and mobile radiography. Radiation Biology: Stochastic vs. deterministic effects, and the relative sensitivity of different tissues. |
| Specialized Modalities & Equipment | ~10-15%: You need foundational knowledge in other areas. CT: Basic principles, terminology (pitch, windowing), and patient safety. MRI: Basic principles and, most importantly, MRI safety protocols (screening for contraindications). Fluoroscopy: Principles and radiation safety practices. Equipment: Components of the x-ray tube, automatic exposure control (AEC), and basic quality control tests. |
Free SCFHS Radiology Technician Exam: Sample MCQs
This collection of MCQs is designed to reflect the practical, scenario-based questions you will face. Analyze each question and its detailed rationale to master the clinical reasoning process. For a comprehensive preparation, a dedicated bank of Saudi Prometric Exam for Radiographers MCQs is your most vital tool.
Question 1: Patient Positioning
A patient with a suspected fracture of the radial head is unable to fully extend their elbow for the AP projection. Which of the following is the best alternative to visualize the radial head without distortion?
- Perform an AP projection with the forearm parallel to the IR and the humerus angled.
- Perform two AP projections: one with the forearm parallel to the IR, and one with the humerus parallel to the IR.
- Perform a lateral projection only.
- Use the Coyle method with the CR angled 45 degrees toward the shoulder.
Correct Answer: B
Rationale: This is a classic trauma radiography scenario. When a patient cannot fully extend their elbow, a single AP projection will result in distortion of the joint space and the radial head. The correct procedure, known as the Jones Method for partial flexion, is to obtain two separate AP projections to ensure a true, non-foreshortened view of both the proximal forearm and the distal humerus. The first image is taken with the forearm parallel to the image receptor (IR), and the second is taken with the humerus parallel to the IR.
Why other options are incorrect:
A: A single projection will not provide a true AP view of the distal humerus in this situation.
C: A lateral projection is essential but is not an alternative to the AP projection; both are required for a complete elbow series.
D: The Coyle method is a specific axiolateral projection used to visualize the radial head, but it is a supplemental view, not a replacement for the standard AP when flexion is limited.
Question 2: Image Production & Evaluation
A radiograph of a PA chest has good overall density but exhibits very low contrast, with the tissues appearing as many shades of gray. Which of the following technical factor adjustments would be most effective in INCREASING the radiographic contrast?
- Increase the mAs by 30%
- Decrease the kVp by 15%
- Increase the SID from 72 to 80 inches
- Use a grid with a lower ratio
Correct Answer: B (Decrease the kVp by 15%)
Rationale: This question tests a fundamental principle of exposure. Radiographic contrast (the difference between adjacent densities) is primarily controlled by kilovoltage peak (kVp). A high kVp produces a long scale of contrast (many grays), while a low kVp produces a short scale of contrast (more black and white). To increase the contrast (make it shorter scale), the kVp must be decreased. The “15% rule” states that decreasing the kVp by 15% will roughly double the contrast (while also halving the density, which would require a doubling of mAs to compensate, but the question only asks how to increase contrast).
Why other options are incorrect:
A: Increasing the mAs would increase the overall density (making the image darker) but would have no significant effect on contrast.
C: Increasing the SID would decrease the density but has only a minor effect on contrast.
D: Using a lower ratio grid would *decrease* contrast because it would be less effective at cleaning up scatter radiation, which is a primary cause of low contrast.
Frequently Asked Questions (FAQs) for the SCFHS Radiology Technician Exam
The SCFHS uses a standardized scoring system where the exam is scored out of 800. The official passing score is 500. This ensures a consistent standard of competency for all candidates.
The core content is very similar, as both are based on the essential competencies of a radiologic technologist. Both heavily emphasize positioning, safety, and image production. The main difference is that the SCFHS exam is not computer-adaptive like the ARRT exam. The questions are pre-set. For information on international standards, you can refer to bodies like the American Society of Radiologic Technologists (ASRT) for their practice standards.
You need a strong, practical understanding of applied physics and biology. You won’t be asked to solve complex theoretical physics problems. Instead, you’ll be asked how a change in a technical factor affects the image and the patient. For biology, you must know the difference between stochastic and deterministic effects and which tissues are most radiosensitive.
No, memorizing specific exposure factors is not required. You need to understand the *relationships* and *relative values*. For example, you should know that a lateral view requires more exposure than an AP view, and a larger patient requires more exposure than a smaller patient. The questions will be conceptual.
Yes, the Primary Source Verification (PSV) by DataFlow is a mandatory part of the SCFHS credentialing process. You must have your qualifications (degree/diploma, license, experience) verified, and receive an eligibility number from the SCFHS before you can book your Prometric exam date.
While a positioning atlas (like *Merrill’s*) is your foundational text, the most effective way to learn for the exam is to use a QBank with image-based questions. Practice critiquing images, identifying the projection, and stating what anatomical structures should be visualized. This active learning method is far superior to passive reading.
The SCFHS generally allows candidates four attempts to pass their licensing exam. There are specific waiting periods between attempts. A failure should prompt a serious re-evaluation of your study strategy, with a much stronger focus on solving a wide variety of MCQs.
No, for the general radiology technician exam, the questions on advanced modalities like CT and MRI are foundational. For MRI, the absolute most important topic is safety—screening for contraindications. For CT, you should know basic terminology and patient safety considerations. You will not be asked about complex protocols.
Pacing is key. You have 1.2 minutes per question on average. Adopt a strategy of answering all the questions you know for sure on a first pass. Flag harder questions and return to them on a second pass. This ensures you secure all the easy points and don’t waste time on a single difficult question.
The final two weeks are for consolidation and simulation. Focus on taking full-length, timed mock exams to build stamina and perfect your pacing. Review your notes on your weakest areas, especially positioning criteria and radiation safety principles. Do not cram new information in the last 48 hours; prioritize rest.
