Report of Chest X-Ray (PA and LateralViews)
Patient Jane HomerStudy # 123456Recorded by Dr. John Smith
The finding is a mass measuring 1.3 cm in diameter with an infiltrative margination.
The baseline image is shown at
ConclusionsThe conclusion is a probable malignancy, inferred from the infiltrative margination of the mass and the appearance shown by the best illustration of findings.
