✦ 2026 edition · organized like the SPI and RDMS exams
354 illustrated pages that turn physics, Doppler and scanning planes into pictures you'll remember, plus the Sonography Coach App: registry-style questions with full explanations, timed SPI, Abdomen and OB/GYN mock exams and a readiness score that tells you when you're ready.
The honest truth about the registry
The SPI is about 110 questions in 2 hours, the Abdomen and OB/GYN exams about 165 and 170 in 3 hours, and you need 555 on a 300–700 scale. Most questions ask you to apply what you know: which knob fixes the image, what the artifact means, what the finding is most likely to be. You only get fast at that by practicing.
You've read Kremkau twice and still have no idea how you'd score tomorrow.
You memorize the formula, then the question asks what happens when you change the depth.
Doppler, artifacts, the liver, the first trimester. So you reread what feels comfortable.
Clinicals, classes, scanning labs. You need to know what to do in the 30 minutes you have.
Until now we told you to pair the bundle with a question bank.
Now the practice is built in, and it's connected to every page of the book.
Introducing
Your study platform for the months before the registry. Open it on your phone between scans at clinicals, on your laptop at night. It tells you what to study today, tests you like the real exams and shows you, in one number, how close you are.
Included in both options
Numbered illustrations, comparison charts, mnemonics, memory tricks and exam alerts on every spread. Every chapter follows the SPI and the Abdomen and OB/GYN specialty exams.
Answers "Am I ready?"
Every question you answer updates one number from 0 to 100, with a separate bar for the SPI, the Abdomen and the OB/GYN exam. It counts your latest answers, how much of each outline you've covered and your mock exams, so it doesn't jump to 100 after a lucky streak.
Answers "Physics doesn't stick"
Written to the official ARDMS content outlines (v24.1): 80 for the SPI, 60 for the Abdomen and 60 for OB/GYN. Answer, and you instantly see why the right answer is right and why each wrong answer is wrong: the formula, the knob, the artifact, the finding. That second part is where the points are.
Answers "Exam-day nerves"
A timed mock for each exam you're taking: the SPI, the Abdomen and the OB/GYN, at the same pace per question as the real ones. Or a 30-question quick check that mixes all three. No hints during the exam, flag questions and come back, then a full review at the end.
Answers "Where am I weak?"
After every set you see your score by exam and by topic. Smart practice then brings your weakest topics to the front and brings missed questions back a day later, when they're about to slip.
Answers "I have no time"
Tell it when your exam is and how much time you have on a normal day. Every morning you get a short list: the flashcards that are due, a set of questions on your weakest topic, two pages to read, and a mock when it's time. Each task checks itself off as you do it.
Answers "I forget what I studied"
Miss a question and one tap opens the exact ebook page that teaches it. The 120 flashcards come back right before you'd forget them (spaced repetition), and the whole ebook is inside the Coach, page by page, so you can study from your phone anywhere.

This is exactly how practice works inside the platform.
A pulsed-wave Doppler examination uses a pulse repetition frequency of 6 kHz. The peak systolic Doppler shift in the vessel is 3.5 kHz. Which statement is correct?
What it looks like
12 flashcards due today on your phone: artifacts and knobology. Four minutes.
10 questions on image optimization, your weakest topic this week. You miss two and read why.
The two ebook pages behind the questions you missed. Plan done, streak kept.
80 questions at exam pace. Your readiness moves from 69 to 75, and image optimization is still your focus.

It's a single payment, never a subscription, and your access never expires: the Coach and the ebook are yours for life, on any device. When we add or update questions, you get them too.
No, and nobody can honestly sell you those: the official questions are secure. Our questions are original, multiple choice, written to the official ARDMS content outlines (v24.1) for the SPI, Abdomen and OB/GYN exams.
They run at the real pace, about 65 seconds per question, but they're shorter: the SPI mock uses all 80 SPI questions (the real SPI is about 110 in 2 hours), and the Abdomen and OB/GYN mocks use all 60 questions of each (the real exams are about 165 and 170 in 3 hours). The real Abdomen and OB/GYN exams also include hotspot questions, where you click on the image; ours are all multiple choice.
It's our estimate of how prepared you are, from 0 to 100, based on your recent answers, how much of each outline you've covered and your mock exams. ARDMS scores every exam on a 300–700 scale and 555 or better passes; it isn't a percentage, so no practice tool can convert your result exactly. A readiness of 80+ and mocks consistently at 70% or more are a good sign you're in range.
Not this edition. The bundle and the Coach cover the SPI plus the Abdomen and OB/GYN specialties, the path most general sonography programs follow.
