Summary
Detecting the scolex is key for diagnosing orbital cysticercosis. This study compared multi-slice CT and 3D steady-state MR imaging, finding both effective for identifying the scolex in orbital cysticercosis cases.
Area of Science:
- Ophthalmology
- Radiology
- Infectious Diseases
Background:
- Orbital cysticercosis, common in endemic regions, involves ocular and extraocular structures.
- The presence of a scolex is the definitive diagnostic marker for cysticercosis.
Purpose of the Study:
- To compare the efficacy of multi-slice computed tomography (CT) and 3D steady-state magnetic resonance (MR) imaging in identifying the scolex in orbital cysticercosis.
Main Methods:
- Three patients with orbital cysticercosis (one ocular, two extra-ocular) underwent imaging.
- Imaging techniques included multi-slice CT with thin coronal and sagittal reformations and a 3D steady-state MR sequence (CISS 3D).
Main Results:
- Both multi-slice CT and 3D steady-state MR imaging were utilized to visualize the scolex in orbital cysticercosis.
- The study included patients with both ocular and extra-ocular involvement.
Conclusions:
- Both multi-slice CT and 3D steady-state MR imaging demonstrate capability in identifying the scolex in orbital cysticercosis.
- Further research may elucidate the specific advantages of each modality for orbital cysticercosis diagnosis.

Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...

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...

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
