1.4 2025 Content Outline, Domain Weights, and Study Strategy

2025 Content Outline, Domain Weights, and Study Strategy

Quick Answer: The current scored blueprint, effective September 1, 2025, is Patient Care 20 (17.4%), Image Production 30 (26.1%), and Procedures 65 (56.5%), totaling 115 scored items. Procedures splits into Anatomy, Physiology, and Pathology 26 and Mammographic Positioning and Procedures 39. The 2025 Annual Exam Report table of 14 / 33 / 26 / 42 is the pre-update exam. Do not study to it. Put more than half of study time on Procedures.

ARRT writes exams from a task inventory built on a practice-analysis survey, then from Examination Content Specifications that list how many scored items sit in each category. Your job is to study the specifications that match the form you will see. For Mammography that means the document Board-approved in July 2024 and implemented September 1, 2025—the same date the clinical worksheet and structured-education category labels moved.

The only scored table you should memorize

Percentages below are 20, 30, and 65 divided by 115, rounded to one decimal place as you will see them in teaching materials. ARRT prints the item counts in bold on the specifications; counts, not marketing percentages, are the legal blueprint.

Patient Care is a single subcategory: communication, assessment of breast-cancer risk, and a working vocabulary of surgical and nonsurgical treatment options. Image Production is a single subcategory that runs from unit design (kVp range, tube, paddles, grids, geometry) through digital acquisition—including full-field digital mammography, digital breast tomosynthesis, and synthesized imaging—into MQSA, EQUIP, breast-density reporting, technologist QC, physicist-test literacy, technique, and image evaluation.

Procedures is the large domain. The anatomy/pathology half expects localization language (clock, quadrant, triangulation), external and internal anatomy, cytology terms, Breast Imaging Reporting and Data System (BI-RADS) appearance, and a catalog of benign, high-risk, and malignant entities. The positioning half expects standard and extra views, patient variance, screening versus diagnostic pathways, and basic knowledge of ultrasound, magnetic resonance imaging, and interventional work. The specifications note that about six items in the positioning section cover the standard craniocaudal (CC) and mediolateral oblique (MLO) views—important, but not the whole 39.

Unscored pilots remain 30. They can come from any category. You cannot skip a “pilot-looking” item. You also cannot earn extra credit by answering them well.

Do not study to the 2025 report’s 14 / 33 / 26 / 42 table

The 2025 Annual Exam Report still shows a four-line topic split that many candidates copy into a study calendar: 14, 33, 26, and 42. Those four numbers sum to 115, so they look official. They describe the pre-September 2025 form, when ARRT allocated scored items differently (including a smaller Patient Care block and a larger positioning block than you face now).

If you budget weeks to that table you will underweight Patient Care (20, not 14) and Image Production (30, not 33) relative to the current exam, and you will overweight the old positioning line (42, not 39). Anatomy’s 26 happened to stay 26, which is how the old table tricks people into thinking nothing moved. Something did move. ARRT’s November 2024 announcement said section question counts were adjusted while the scored total stayed 115 and pilots rose from 25 to 30.

Use the Annual Exam Report for the 87.9% first-attempt pass rate and the approximate 66 percent-correct line. Use the content specifications PDF for what to study.

September 2025 additions and removals (high level)

ARRT’s November 6, 2024 overview is the checklist for what changed in the outline. You do not need a redline of every bullet, but you should not drill retired flaps or ignore new informatics language.

Added or expanded

• Patient Care: patient education on the process for receiving results; more detail on inherent and social risk factors (including access to care, hormone use, and related history).
• Image Production: synthesized imaging and PACS troubleshooting; breast density reporting under MQSA; EQUIP and patient-related artifacts under technique and image evaluation.
• Procedures: additional patient-preparation detail under interventional procedures (history, consent, time-out, setup, postprocedure instructions).

Removed

• Patient Care: transverse rectus abdominis myocutaneous (TRAM) flap and latissimus dorsi flap as tested reconstruction labels.
• Procedures: sentinel node mapping, cyst aspiration, and fine-needle aspiration biopsy as tested interventional items.

Stereotactic and ultrasound biopsy knowledge, wire localization, specimen imaging, and clip placement remain in the outline at the basic-knowledge level the specifications describe. Do not infer that all biopsy content disappeared because fine-needle aspiration did.

Weight study time to match scored items

A fair hour budget for a candidate who already works in mammography is not equal thirds. Procedures is 65 of 115 scored items—more than Patient Care and Image Production combined. If you have 20 focused study sessions, a count-matched split is about 3.5 sessions Patient Care, 5 sessions Image Production, and 11.5 sessions Procedures. Inside Procedures, give positioning slightly more time than anatomy (39 versus 26), but do not skip BI-RADS lexicon; those 26 items are still larger than the entire Patient Care domain.

Practical translation:

• Patient Care (20): scripts for deodorant and clothing, screening-guideline questions, documenting scars and moles, risk factors you can explain without practicing medicine, and treatment terms at definition level.
• Image Production (30): why mammography kVp and target/filter pairs differ from general radiography, compression, grids, tomosynthesis versus 2D versus synthesized images, labeling, MQSA recordkeeping, EQUIP corrective action, and the technologist QC tests you already log for clinicals.
• Procedures (65): CC and MLO criteria first, then extras (exaggerated craniocaudal, cleavage, rolled, implant-displaced, spot, magnification), then pathology appearance, then the interventional vocabulary that remains after the 2025 deletions.

Work clinicals and didactic study on the same calendar. Phantom QC repetitions teach Image Production. The EQUIP consult with an interpreting physician teaches the image-evaluation language that now sits explicitly in the outline. The 75 independent patient exams teach positioning far better than a second pass through a slide deck—if you evaluate your own images against ACR clinical-image criteria instead of only counting worksheet rows.

When a practice question still uses the old four-domain labels or tests TRAM flaps as current outline content, discard it. The current specifications PDF is short. If a resource cannot match that table, it is not a 2026 resource.
