The ACR provides comprehensive practice parameters for diagnostic imaging reporting to ensure quality, consistency, and communication effectiveness.
1. Patient Demographics
2. Procedure/Examination
3. Clinical Indication
4. Comparison
5. Technique
Technique: Multiplanar T1 and T2-weighted sequences were obtained through
the brain without and with IV contrast. 15 mL of gadolinium-based contrast
agent was administered intravenously. Technical quality is adequate.
6. Findings
Organization approaches:
7. Impression/Conclusion
Example:
IMPRESSION:
1. 3.2 cm enhancing mass in the right frontal lobe with surrounding vasogenic
edema, most consistent with high-grade glioma. Metastasis cannot be excluded.
Clinical correlation and tissue sampling recommended.
2. No acute intracranial hemorrhage or herniation.
3. Recommend neurosurgical consultation.
8. Critical Results Communication
Used for lung cancer screening CT interpretation.

GROSS DESCRIPTION:
Received fresh, labeled with patient name and "left breast, lumpectomy" is an
oriented lumpectomy specimen measuring 8.5 x 6.0 x 4.0 cm, with a suture
indicating superior margin. Inking: superior - blue, inferior - black, medial -
green, lateral - red, anterior - orange, posterior - yellow. Serially sectioned
to reveal a firm, gray-white mass measuring 2.1 x 1.8 x 1.5 cm, located 2.5 cm
from superior, 3.0 cm from inferior, 2.0 cm from medial, 3.5 cm from lateral,
1.5 cm from anterior, and 1.8 cm from posterior margins. Representative sections
submitted as follows: A1-A3 tumor, A4 superior margin, A5 medial margin, A6
posterior margin.

Example:
Test: BRCA1/BRCA2 Full Gene Sequencing
Result: PATHOGENIC VARIANT DETECTED
Gene: BRCA1
Variant: c.68_69delAG (p.Glu23ValfsTer17)
Classification: Pathogenic
Interpretation: This variant is associated with increased risk of breast and
ovarian cancer. Genetic counseling and risk-reducing strategies recommended.
Family testing should be considered.
