Summary
Unusual ghost images appeared on a panoramic radiograph due to earrings. This case highlights the importance of understanding artifact formation in dental imaging for accurate diagnosis.
Area of Science:
- Radiology
- Dental Imaging
- Radiographic Interpretation
Background:
- Panoramic radiography is a common dental imaging technique.
- Artifacts can compromise the diagnostic quality of radiographic images.
- Understanding image formation principles is crucial for artifact identification.
Observation:
- A 9-year-old female patient's panoramic radiograph revealed unexpected shadows.
- Earrings worn during the procedure caused artefactual shadows.
- Two real images and three unusual ghost images of the earrings were observed.
Findings:
- The presence of earrings led to the formation of multiple ghost images.
- The number and appearance of the ghost images were atypical.
- Analysis revisited the principles of panoramic radiology concerning ghost image generation.
Implications:
- This case emphasizes the need for patient preparation to avoid artifacts in panoramic radiography.
- Accurate interpretation requires awareness of potential ghost image sources.
- Proper technique and patient instructions can prevent diagnostic errors caused by artifacts.

01:24X-ray Imaging
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
01:10Computed Tomography
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...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
