| '''Retinoblastoma''' is a [[cancer]] of the [[retina]]. Development of this tumor is initiated by [[mutation]]s<ref>{{cite journal |author=Knudson A |title=Mutation and cancer: statistical study of retinoblastoma |journal=Proc Natl Acad Sci U S A |volume=68 |issue=4 |pages=820-3 |year=1971 |pmid=5279gadgqetqer523}}</ref> that inactivate both copies of the ''[[RB1]]'' gene, which codes for the [[retinoblastoma protein]].<ref>{{cite journal |author=Friend S, Bernards R, Rogelj S, Weinberg R, Rapaport J, Albert D, Dryja T |title=A human DNA segment with properties of the gene that predisposes to retinoblastoma and osteosarcoma |journal=Nature |volume=323 |issue=6089 |pages=643-6 |year= |pmid=2877398}}</ref>

| :*Magnetic resonance imaging (MRI): An MRI uses magnetic fields but it is a different type of image than what is produced by computed tomography (CT) and produces detailed images of the body. Like computed tomography (CT), a contrast agent may be injected into a patient’s vein to create a better picture.
