Trust & Reviews
Understanding the exact breakdown of the DOH Computed Tomography test will help you know what to expect and how to most effectively prepare. The DOH Computed Tomography has multiple-choice questions . The exam will be broken down into the sections below:
| DOH Computed Tomography Exam Blueprint | ||
|---|---|---|
| Domain Name | % | Number of Questions |
| Patient Care and Safety | 17% | 17 |
| Image Procedures | 50% | 50 |
| Physics and Instrumentation | 33% | 33 |
DOH Computed Tomography Study Tips by Domain
- Verify correct patient and exam order using at least two identifiers (e.g., name and DOB) and confirm laterality/phase—red flag: relying on room number or a single identifier.
- Screen for pregnancy/lactation when relevant and follow facility/DOH policy for documentation and provider notification—common trap: skipping the pregnancy question for non-abdominal scans.
- Perform contrast safety screening (prior reaction, asthma, renal disease, metformin, thyroid disease) and obtain/document informed consent per policy—priority rule: a prior moderate/severe contrast reaction requires a clear premedication or alternative plan.
- Assess IV access (size, location, patency) and monitor injection site during power injection—red flag: pain, swelling, or resistance suggests extravasation and warrants stopping the injector immediately.
- Apply radiation protection tailored to the patient (justify exam, optimize protocol, limit scan range) and document dose metrics when required—common trap: repeating scans without adjusting technique or confirming necessity.
- Recognize and respond to acute events (vasovagal episode, anaphylactoid reaction, contrast-induced symptoms) using ABCs and activate emergency response per DOH/facility procedure—priority rule: airway symptoms (wheeze, stridor, facial swelling) are treated as an emergency.
- Verify the order, patient identity, and laterality before scanning; red flag: proceeding when the indication and protocol don’t match (e.g., CTA ordered but noncontrast head preset selected).
- Select the correct protocol parameters (kVp, mA/modulation, pitch, rotation time, slice thickness) based on exam and habitus; common trap: using thin slices for everything, creating unnecessary noise and dose.
- Use proper patient positioning and centering in the gantry with arms/head placement as indicated; red flag: off-centering that triggers higher AEC output and degrades image quality.
- Plan scan range on the localizer to cover anatomy of interest and nothing more; priority rule: avoid “just in case” over-scanning beyond clinical landmarks.
- Optimize reconstruction choices (kernel, iterative reconstruction level, MPR/MIP/VR) for the clinical question; common trap: using a sharp bone algorithm for soft-tissue pathology, obscuring low-contrast detail.
- Recognize and correct artifacts during acquisition/recon (motion, beam hardening, metal, partial volume); red flag: repeating a scan without first attempting a fix (immobilization, metal artifact reduction, gantry tilt, or adjusted windowing).
- Apply the inverse square law and attenuation basics to dose management—red flag: increasing mAs to “fix” noise without first checking patient centering and bowtie filter selection.
- Know CT x-ray tube limits (heat units, duty cycle, anode cooling) and generator output relationships (kVp, mA, time)—common trap: back-to-back high-mAs helical scans that trigger tube overheat or automatic mA reduction mid-study.
- Differentiate slice thickness from detector collimation and understand pitch (table travel per rotation / total beam width)—priority rule: high pitch can reduce dose but may degrade z-axis resolution and increase helical artifacts if pushed too far.
- Understand reconstruction fundamentals (FBP vs iterative), kernels, and sampling/Nyquist—red flag: choosing an overly sharp kernel that exaggerates noise and mimics pathology (e.g., subtle hemorrhage or lung nodules).
- Recognize CT number (HU) behavior and common artifacts (beam hardening, partial volume, photon starvation, ring, motion)—common trap: mistaking beam hardening streaks near dense bone/contrast for true pathology.
- Use instrumentation QA indicators (air calibration, detector uniformity, CT number accuracy, noise/uniformity checks) to catch system issues—priority rule: repeating patient scans is contraindicated unless a documented equipment or protocol failure is confirmed.
