Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Anatomy of the Eyeball

Anatomy of the Eyeball

The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...

Summary

A young woman

Area of Science:

Ophthalmology and Neurology
Neuroimaging and Diagnostic Techniques

Background:

Headaches can be a symptom of increased intracranial pressure.
Papilledema, or swelling of the optic disc, is a key sign of such pressure.
Differentiating true papilledema from other optic disc anomalies is crucial.

Observation:

A young woman presented with headaches and signs of papilledema.
Magnetic Resonance Imaging (MRI) of the brain revealed no intracranial abnormalities.
Orbital MRI identified specific features in the left eye.

Findings:

The orbital MRI demonstrated oblique optic nerve insertion and posterior nasal globe flattening.
These findings are characteristic of congenitally tilted optic discs.
This case highlights the utility of orbital MRI in diagnosing optic disc anomalies.

Implications:

Congenitally tilted optic discs can mimic papilledema, leading to potential misdiagnosis.
Orbital MRI is a valuable tool for visualizing optic nerve and globe morphology.
Accurate diagnosis prevents unnecessary investigations for intracranial pathology.
