Fungal splenic abscesses in the immunosuppressed patient. Correlation of imaging modalities.

A patient with fungal splenic abscesses is presented in whom multiple noninvasive diagnostic imaging modalities were available for correlation. Of the five imaging modalities, three (Gallium-67, ultrasound and computed tomography) were diagnostically useful, while two (liver-spleen scan and In-111 white blood cell scan) were not as useful. This case also stresses the use of repeated studies correlating with clinical impressions to obtain an accurate diagnosis in a potentially life-threatening condition such as splenic abscess.

Visual perception and xerography.

An electrostatic copying machine was used to model the perception of simultaneous brightness contrast. Such a model may assist the study of sensory inhibition by permitting the study of complex situations as they are transformed by rules similar to those at work in neural integration.
