A radiology report is a formal medical document created by a specialist physician, the radiologist, after interpreting medical imaging studies such as X-rays, Computed Tomography (CT) scans, Magnetic Resonance Imaging (MRI), or ultrasounds. This report is the primary method of communicating the findings from these images to the referring physician who ordered the test. Its purpose is to provide an accurate, objective description of what was seen, alongside a professional interpretation, which guides the patient’s diagnosis and treatment plan.
The Creation Process
The process of generating a report begins immediately after the patient’s imaging study is completed and the images are available for review. The radiologist, a medical doctor (MD or DO) with specialized training, views the images on a high-resolution workstation. The specialist interprets the images by comparing the patient’s anatomy to expected norms and looking for any changes or abnormalities.
Following the interpretation, the radiologist records their detailed observations and conclusions through dictation. This verbal recording is then converted into a written document via transcription, often using automated speech-recognition software. The radiologist is the ultimate author and must thoroughly review the transcribed document for accuracy and clarity.
The final step is verification, where the radiologist electronically signs the report, making it an official part of the patient’s medical record. Until this signature is applied, the findings are considered preliminary; once signed, the report becomes a legal document. This document is immediately transmitted back to the referring physician and often made available to the patient.
Essential Components of the Report
A standard radiology report is structured into distinct sections, each serving a specific function for the referring provider. The report begins with the Clinical History or Indication, which briefly states the reason the imaging study was requested, such as “ruling out fracture after a fall.” This section focuses the radiologist’s interpretation on the primary clinical question.
The Comparison section notes any previous relevant imaging studies reviewed alongside the current one. Comparing new images to older ones helps determine if a finding is new, stable, or changing over time, aiding in diagnosis and monitoring chronic conditions. The Technique section details how the study was performed, listing the specific machine, views taken, and whether contrast material was administered.
The largest and most descriptive section is the Findings, which is an objective, detailed account of everything the radiologist observed on the images. This includes descriptions of normal anatomy and any detected abnormalities, often with precise measurements and locations. This section is purely descriptive, avoids offering a diagnosis, and uses technical language to ensure precision in communication between medical specialists.
Finally, the Impression or Conclusion synthesizes the detailed observations from the Findings section into a concise summary and interpretation. This is the most important part for the referring doctor, as it provides the radiologist’s professional opinion, often listing the most likely diagnoses, known as the differential diagnosis. The Impression may also include recommendations for follow-up studies, such as a biopsy, to further clarify the findings.
Decoding the Language
The technical nature of the Findings section often makes the report difficult for patients to understand, as it is written for other medical professionals. Certain words frequently cause confusion because they sound alarming or are medically vague. The term “lesion,” for example, is a broad, neutral descriptor for any area of abnormal tissue, which could be anything from a harmless cyst to a tumor.
Similarly, a “mass” is a general term for any unexpected tissue growth or volume and does not automatically imply cancer. Phrases like “unremarkable” or “no acute findings” are generally good news. “Unremarkable” means the radiologist found nothing abnormal or concerning, while “no acute findings” means there is no evidence of an immediate, severe problem like a new fracture or active bleeding.
The differential diagnosis is a list of possible conditions that share the same signs or symptoms, ranked by the radiologist based on the imaging appearance. This list is not a final diagnosis, but a guide for the referring physician to order further tests or begin a targeted treatment plan. Radiologists use this precise terminology to avoid ambiguity and ensure clarity when communicating complex visual data.
Communication and Follow-Up
Once the report is signed, it is instantly transmitted to the referring physician’s office through secure electronic health record systems. This provider, who ordered the test, integrates the report’s findings with the patient’s symptoms and other test results. Timely communication is necessary, especially if the report contains an unexpected or urgent finding that requires immediate action.
Many patients can now access their reports directly through online patient portals, sometimes before their doctor has reviewed them. Reading the report without clinical context can lead to anxiety, particularly when encountering technical terms like “mass” or “lesion.” Patients should understand that the referring physician will explain the results, place them in the context of overall health, and discuss necessary next steps. The report is a powerful diagnostic tool, but the final interpretation and treatment plan must be determined in consultation with the ordering provider.
