ABR IR/DR common mistakes
ABR IR/DR · Understand the traps and how to avoid them.
Memorizing catheter/device specifications (French sizes, lengths, rated burst pressures) as isolated numbers rather than as a decision rule tied to the vessel or lesion.
Study resources present device tables, so candidates rehearse recall of numbers instead of the clinical selection logic the exam tests.
What to do instead
For each device, write one line: 'I choose X over Y when [vessel/lesion feature], because [property].' Rehearse the selection sentence, not the spec sheet.
Answering embolization or ablation questions with the technique name only, omitting the endpoint or success criterion (e.g., stasis vs. near-stasis, residual enhancement, expected post-procedure imaging appearance).
Candidates learn procedures as sequences of steps and skip the 'how do you know it worked' portion, which is where the discriminating options live.
What to do instead
After every procedure, state its angiographic or imaging endpoint and the expected follow-up finding; quiz yourself on endpoints only.
Treating complication management as 'call surgery' by default instead of matching the complication to a graded, image-guided first step.
Complication algorithms are memorized as lists without the branch points, so candidates pick the most aggressive option under time pressure.
What to do instead
Build a decision tree per complication (e.g., access-site hemorrhage, biliary leak, abscess) with the first-line percutaneous step and the explicit trigger for escalation.
Confusing which modality or sequence answers a specific clinical question, e.g., choosing contrast-enhanced CT when the stem is asking about a finding best seen on a fluid-sensitive sequence or a specific ultrasound mode.
Candidates study modalities in isolation and never practice 'given this question, which test' framing.
What to do instead
Drill modality-selection vignettes in reverse: read the answer choices first and justify why each wrong modality fails the specific question.
Reading a case stem once and committing to an answer before extracting the discriminating detail (patient age, immune status, duration, laterality, prior treatment).
Time pressure plus pattern recognition leads to 'looks like X' closure; exam stems bury the one fact that changes the differential.
What to do instead
Force a two-pass habit: first pass list the 3-4 objective findings, second pass pick the diagnosis; practice on timed sets until the two-pass routine is automatic.
Describing imaging findings with generic descriptors ('mass', 'lesion', 'abnormal signal') instead of the specific morphologic and anatomic terms the answer options use.
Candidates know the diagnosis but not the lexicon, so they cannot match their reasoning to the correct option.
What to do instead
Maintain a running glossary pairing each diagnosis with its required descriptor set (location, margin, internal characteristics, associated finding) and self-test with image-free descriptions.
Ignoring the physics/safety dimension of a modality question, e.g., answering an image-quality or artifact question with an anatomy-based explanation.
Physics is studied as a separate block and not integrated into case interpretation.
What to do instead
For each artifact or quality issue, write the mechanism and the parameter that controls it; practice classifying mixed questions as 'physics' vs. 'pathology' before answering.
Guessing on questions that hinge on a guideline threshold (screening interval, follow-up timing, size cutoff) rather than knowing the number cold.
Thresholds feel low-yield, so candidates learn the concept but not the value, and distractor options are built around near-miss numbers.
What to do instead
Keep a single one-page table of numeric thresholds by organ system and review it weekly; flag any threshold you cannot state without hesitation.
Failing to distinguish 'next best step' from 'most likely diagnosis' questions and answering with the diagnosis when the stem asks for management (or vice versa).
Stems are long and the question word is at the end; candidates answer the question they expected rather than the one asked.
What to do instead
Underline the interrogative in every practice stem before looking at options; tally your misreads to confirm the pattern, then re-drill.
Reviewing missed questions by reading the explanation once instead of converting each miss into a retrievable rule that is re-tested later.
Recognition feels like mastery; without spaced retrieval the same concept fails again on a differently worded item.
What to do instead
Log each miss as a one-sentence rule plus the trap that fooled you, and re-quiz those rules at 1 week and 1 month; retire a rule only after two clean correct answers.
