Medical - Medical: Dentistry / Immunohistochemistry | | Portuguese term or phrase: artefatos de técnica | | "Quando houve dúvida quanto à camada de origem de uma célula, optou-se pela sua exclusão do estudo. Também foram excluídas células com núcleos sobrepostos ou dobrados e áreas com presença de artefatos de técnica." |

2 hrs confidence:   technique artifacts
Explanation:
Patient-based artifacts are caused by such factors as patient movement or the presence of metallic materials in or on the patient. Scanner-based artifacts result from imperfections in scanner function. Helical and multisection technique artifacts are produced by the image reconstruction process. Design features incorporated into modern CT scanners minimize some types of artifacts, and some can be partially corrected by the scanner software. However, in many instances, careful patient positioning and optimum selection of scanning parameters are the most important factors in avoiding CT artifact.

Um dos grandes desafios foi provar que os filamentos observados não eram simples "artefatos
de técnica", isto é, estruturas artificialmente criadas pelos tratamentos aos quais as células são submetidas para permitir sua observação (fixação, corte, coloração, etc.).

Artifacts
Artifacts are structures or features in tissue that interfere with normal histological examination. These are not always present in normal tissue and can come from outside sources. Artifacts interfere with histology by changing the tissues appearance and hiding structures. These can be divided into two categories.
