Key Facts: DACBR Exam
DACBR is the post-doctoral specialty diplomate for chiropractic radiology. Eligibility requires a Doctor of Chiropractic degree, active license, and completion (or final-year enrollment) of a 3-4 year full-time chiropractic radiology residency. Candidates have 4 consecutive calendar years to complete both Part 1 and Part 2, with a maximum of 3 attempts per part. Examination content spans positioning/technique, normal anatomy, ABCS pathology search, arthritides, trauma classification, tumors, metabolic bone disease, infection, congenital anomalies, MRI/CT/ultrasound, radiation safety, and ACR Appropriateness Criteria.

1A lateral cervical spine radiograph in a 35-year-old shows complete loss of the C5-C6 disc space height, end-plate sclerosis, anterior osteophyte bridging, and absent facet erosions. ABCS analysis most likely supports which diagnosis?
2A pediatric distal radius fracture shows a fracture line that traverses the physis and exits through the metaphysis only, without epiphyseal involvement. Per the Salter-Harris classification, this is which type?
3On a knee MRI, a lesion in the distal femur is dark (low signal) on T1 and bright (high signal) on T2 with STIR hyperintensity. The most accurate single-sequence inference is:
4A 14-year-old presents with night pain in the proximal tibia relieved by NSAIDs. Radiograph shows a 1-cm radiolucent nidus surrounded by dense cortical reactive sclerosis in the diaphysis. The most likely diagnosis is:
5ALARA principles in chiropractic radiography are best served by which of the following technique changes when image quality is otherwise acceptable?
6An anteroposterior pelvis radiograph in a 28-year-old with chronic low back pain shows bilateral, symmetric blurring and erosion of the SI joint cortex with adjacent sclerosis. The next vertebral-body finding most consistent with the unifying diagnosis would be:
7A lateral knee radiograph in a 45-year-old skier shows a tibial plateau fracture with pure cleavage of the lateral plateau and a vertical split, no depression. Per Schatzker classification, this is type:
8Codman triangle, sunburst spiculation, and aggressive periosteal reaction in the distal femur of a 16-year-old most strongly suggest:
9A 72-year-old woman has a DEXA hip T-score of -2.7. By WHO criteria, this places her in which category?
10A chest radiograph incidental finding shows a smoothly marginated 5-mm pulmonary nodule in the right upper lobe of a 35-year-old non-smoker. The most appropriate next step per Fleischner Society 2017 guidelines is:
About the DACBR Exam
The DACBR (Diplomate of the American Chiropractic Board of Radiology) certifies chiropractic radiologists who have completed a full-time 3-4 year postgraduate radiology residency. The credential is recognized across chiropractic education and clinical referral networks for image interpretation, teleradiology, and faculty appointments. Certification is granted only after passing both Part 1 and Part 2 of the ACBR examination.

Frequently Asked Questions
What is the DACBR exam format?
DACBR is a two-part written examination (Part 1 and Part 2) administered annually by the American Chiropractic Board of Radiology. Item counts are set per administration and include scored questions plus unscored pilot items used for future test development.
What are the eligibility requirements?
Candidates must hold a Doctor of Chiropractic degree, be licensed (or eligible for licensure) to practice as a chiropractor, and be enrolled in the final year or have completed a 3- or 4-year full-time postgraduate chiropractic radiology residency.
How many attempts are allowed?
Candidates have four consecutive calendar years from initial eligibility to complete both Part 1 and Part 2, with a maximum of three attempts per part within that window.
Who administers the DACBR exam?
The American Chiropractic Board of Radiology (ACBR), an independent specialty board. The companion academic society is the American Chiropractic College of Radiology (ACCR).
How is the DACBR exam scored?
Scoring is criterion-referenced. ACBR subject-matter experts establish the minimally competent candidate standard for each examination form; the published pass/fail decision is based on that standard, not a fixed percent score.
What imaging modalities are tested?
Plain-film radiography is the largest body of content, but candidates are also tested on MRI (T1/T2/STIR/FLAIR signal characteristics), CT (windowing and 3D reconstruction), musculoskeletal ultrasound basics, and ACR Appropriateness Criteria for modality selection.
Does the DACBR cover non-musculoskeletal imaging?
Yes. While MSK is the dominant body of content, candidates must also recognize relevant chest, abdomen, and head/neck findings, including incidental findings that warrant referral, and understand basic radiation safety and contrast administration principles.
