“…Of the different anatomic planes used, the oblique dorsal and oblique sagittal images were the most valuable for evaluating the orbit and optic pathways (Figs. [4][5][6][7][8][9]. Although transverse and straight sagittal sections allowed precise visualization of the brain, orbital structures were sometimes difficult to evaluate.…”

Magnetic resonance (MR) images of the normal eye and orbit of the dog and cat were acquired. T1‐weighted, proton‐density, and T2‐weighed images were obtained in the oblique dorsal, straight sagittal, and oblique sagittal planes. Signal intensity for the various orbital structures differed among the three resonance techniques. T1‐weighted images provided the greatest contrast of the retrobulbar structures. T‐1 weighted images also had the highest signal to noise ratio, thereby providing the best anatomic detail. Anatomic components of the globe, retrobulbar structures and ocular adnexa were easily seen in all MR sections. The oblique dorsal and oblique sagittal planes were superior for evaluating the optic nerve in its entirety.

“…Der hohe Kontrast zwischen grauer und weiIer Substanz, der eine gute Differenzierung von normalen und defizitären Myelinisierungsvorgängen gestattet und die weitgehend uberlagerungs-und artefaktfreie Abbildung in 3 Ebenen ermöglichen eine uberlegene Gewebsdifferenzierung und lassen diese Methode ideal für die Diagnose verschiedener zentraler neurologischer Krankheitsbilder erscheinen (8,19,21,22,26,28,34,35). Im Gegensatz zur hohen Sensitivitãt der MR-Technik ist die Spezifitãt dieses neuen diagnostischen Verfahrens nach dem heutigen Erkenntnisstand geringer einzuschãtzen (1,17,24,30,33).…”
