Is It Real or Is It an Artifact

Ultrasound Quarterly, 2001
Sonographic artifacts are inherent to the modality and occur to some extent in every image. This is despite optimal technique and scanning parameters. Artifacts occur in both gray-scale and color Doppler imaging, and though many are readily recognizable as such, occasionally, an artifact may obscure the diagnosis or even create false pathology.

Condensation Artifact

Journal of Magnetic Resonance Imaging, 2021
During the ongoing COVID‐19 pandemic, an artifact with hyperintense signal was observed on the brain images of a number of patients or research subjects, particularly those with heavy body weight and/or increased respiratory rate. The artifact was primarily seen on 3D or 2D sagittal or coronal T2‐weighted images, although it occasionally also appeared ...

The artifact of retinoscopy

Vision Research, 1978
Abstract The results of retinoscopic refraction measurements in rabbits are compared with the results of two alternative refraction methods. In one of these methods the response to moving gratings is measured in relation to the added lenspower; in the second method retinoscopy is executed with monochromatic lights. From the results of both methods it

The Urinal Artifact

Radiology, 1978
Abrupt narrowing of the male anterior urethra has been increasingly observed during voiding cystourethrography due to extrinsic pressure from a urinal. The true nature of this narrowing must be recognized to avoid misinterpretation.
