Key Takeaways Explain This Topic AI
The 360 scored questions divide into Patient Care 26 (7.2%), Image Production 118 (32.8%), and Procedures 216 (60%) — physics plus procedures dominate the exam
Image Production splits into Basic Principles of Ultrasound (45), Image Formation (47), and Evaluation and Selection of Representative Images (26)
Procedures splits into Abdomen (75), First Trimester Obstetrics (20), Second/Third Trimester and High Risk Obstetrics (57), Gynecology (32), and Superficial Structures (32)
Study time should be allocated in rough proportion to blueprint weights — about 60% procedures, 33% physics and instrumentation, 7% patient care
A 12-20 week plan with full-length, two-session practice exams builds both the content mastery and the endurance the 400-item format demands

The Official Blueprint
ARRT's Examination Content Specifications for Sonography fix the number of scored questions in every content category and subcategory. These counts are not approximate — they are the skeleton the exam is built from, and they should be the skeleton of your study plan too.
- Content Category Scored Questions Share of 360
- Patient Care — Patient Interactions and Management 26 7.2%
- Image Production — total 118 32.8%
- Basic Principles of Ultrasound (45)
- Image Formation (47)
- Evaluation and Selection of Representative Images (26)
- Procedures — total 216 60.0%
- Abdomen (75)
- First Trimester Obstetrics (20)
- Second/Third Trimester and High Risk Obstetrics (57)
- Gynecology (32)
- Superficial Structures and Other Sonographic Procedures (32)
- Total scored 360 100%
- Reading the Blueprint Like a Strategist
Three observations should shape your preparation:
Physics and procedures dominate. Image Production (118) plus Procedures (216) account for 334 of 360 scored questions — 92.8 percent of the exam. The single largest subcategory on the entire test is Abdomen at 75 questions, and the three physics subcategories together (118) outweigh every procedure subcategory individually.
The heavyweight sections are also the gated sections. As covered in Section 1.2, the abdominal and OB/GYN procedure sections carry section minimums. Conveniently, those same sections hold 75 + 20 + 57 + 32 = 184 questions , over half the exam. Preparing hardest for the biggest sections is also preparing for the sections that can veto your result.
Patient Care is small but not free. Twenty-six questions is only 7.2 percent, but these are often the most learnable items on the exam — ethics, HIPAA, infection control, ergonomics, medical emergencies. A few focused sessions can convert this section into near-automatic points.
Domain-Proportional Time Allocation
Whatever total study window you choose, split your hours in rough proportion to the weights. For a concrete example, a 16-week plan at 8 hours per week (128 hours) might allocate:
Procedures — about 77 hours (60%): roughly 27 hours abdomen, 20 hours OB (first trimester plus second/third trimester and high risk), 15 hours gynecology, 15 hours superficial structures.
Image Production — about 42 hours (33%): roughly 16 hours basic principles, 17 hours image formation and artifacts, 9 hours image evaluation and optimization.
Patient Care — about 9 hours (7%): concentrated review in the final third of the plan.
Most candidates find a 12-20 week window realistic: 12 weeks suits recent graduates whose coursework is fresh, while candidates working full-time or returning to the field should plan closer to 20 weeks. Shorter than 12 weeks rarely leaves room for the physics depth and full-length practice the exam demands.
Two-Session Endurance Training
Content knowledge fails candidates less often than stamina does. Four hundred questions across ~390 minutes of testing is a different physiological task than the 50-question quizzes most review resources serve up. Build endurance deliberately:
Start with untimed topic quizzes in weeks 1-4 to diagnose weaknesses.
Move to timed 60-question blocks at ~1 minute per question by mid-plan.
In the final 3-4 weeks, complete at least two full-length simulations : a 240-item morning session, a 30-minute break, then a 160-item afternoon session, under real timing with no notes.
Score every simulation by blueprint section , not just overall. A total score of 80 with a weak OB/GYN section is a failing exam profile under the section-minimum rule; track each domain separately and let the weakest designated section set your review priorities.
Putting It Together
The study guide that follows this chapter mirrors the blueprint order: patient care foundations, then the physics and instrumentation chapters that feed 118 questions, then the five procedure domains in their blueprint weight. Use the outline subcategory counts as a checklist — when you can teach back the key concepts under a subcategory and score consistently above 80 percent on its practice items with no single domain lagging, you are ready to schedule. Given the roughly 55 percent pass rate reported in ARRT's 2025 Annual Exam Report and the three-attempts-in-three-years limit, the goal is to sit once, prepared, rather than to sit early.
Tactics Matched to Each Domain
Image Production (118 questions): memorize core relationships until recall is automatic — the 1540 m/s average soft-tissue propagation speed, the 13 microseconds per centimeter round-trip rule, the inverse relationship between frequency and penetration, and the determinants of axial versus lateral resolution. Then drill artifact recognition (reverberation, posterior shadowing, through-transmission enhancement, mirror image, aliasing) from descriptions and still frames, because Evaluation and Selection items frequently ask which control corrects a named artifact.
Abdomen and OB/GYN (184 questions combined): organize study around normal anatomy, normal measurements, common pathology, and scanning protocol for each organ system and each trimester. These sections reward systematic memorization of standard values — for example, mean sac diameter and crown-rump length dating in the first trimester, and biometry such as biparietal diameter and femur length later in pregnancy.
Gynecology and Superficial Structures (64 questions combined): smaller but dense; thyroid, breast, scrotal, and superficial soft-tissue content follows the same anatomy-measurement-pathology grid as the abdomen.
Patient Care (26 questions): one or two concentrated sessions on HIPAA, informed consent, the infection-control chain, ergonomics, and emergency response typically suffice; use scenario-style practice to lock them in.
Close every week with a mixed timed quiz that samples all domains in blueprint proportion — roughly six procedure questions and three physics questions for every one patient-care question — so your practice mix always mirrors the real exam's 60/33/7 split.
