X-ray Imaging01:24

X-ray Imaging

7.7K
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...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

987
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 Investigation III: Pulmonary Angiogram and PET Scan

716
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...

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,...

    Summary

    This study details tooth root resorption types, differentiating internal and external resorption. Accurate diagnosis using advanced imaging like cone beam computed tomography (CBCT) is crucial for effective treatment planning.

    Area of Science:

    • Dentistry
    • Oral Pathology
    • Radiology

    Background:

    • Tooth root resorption is a pathological process affecting dental structures.
    • Internal and external resorption have distinct etiologies and clinical presentations.
    • Accurate differentiation is critical for appropriate management.

    Purpose of the Study:

    • To present the clinical, radiographic, and histopathologic features of various tooth root resorption types.
    • To emphasize the importance of correct diagnosis in managing resorption.
    • To discuss the utility of cone beam computed tomography (CBCT) and 2-D imaging in evaluating resorptive lesions.

    Main Methods:

    • Review of clinical, radiographic, and histopathologic data from cases of tooth root resorption.
    • Comparative analysis of imaging modalities, including cone beam computed tomography (CBCT) and conventional 2-D intraoral radiography.
