Imaging Studies III: Computed Tomography

418
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...

Area Computation by the Alternative Coordinate Method

675
The alternative coordinate method, also known as the Shoelace Formula, is a technique for determining the area of a traverse using Cartesian coordinates. This method relies on the sequential arrangement of x and y coordinates for each point of the shape, ensuring accuracy and ease of application.In this approach, each corner's x and y coordinates are listed as fractions, with the x-coordinate as the numerator and the y-coordinate as the denominator. These coordinates are arranged sequentially...

Design Example: Traverse Angle Computations

348
Traverse angle computations are a critical component of surveying, used to compute the internal angles within a closed traverse. A traverse consists of a series of connected lines forming a closed loop, often used for land boundary delineation or mapping. Calculating the internal angles ensures accuracy in the traverse geometry and is essential for checking survey data integrity.The process begins with known azimuths and bearings of the traverse sides. Internal angles at each vertex are...

Computed Tomography

9.0K
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...

Psychosurgery

1.9K
Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
Historical Development of Psychosurgery
In the 1930s, Portuguese neurologist Antonio Egas Moniz introduced a surgical procedure designed...

Positron Emission Tomography01:29

Positron Emission Tomography

7.7K
Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

    Summary
    This summary is machine-generated.

    Computed tomography scans revealed bilateral frontal lobe cysts in patients after frontal leukotomy. These cysts mimic cerebrospinal fluid on scans and do not enhance with contrast dye.

    Area of Science:

    • Neurology
    • Radiology
    • Neurosurgery

    Background:

    • Frontal leukotomy, a historical neurosurgical procedure, can lead to various post-operative changes.
    • Understanding the imaging characteristics of these changes is crucial for accurate diagnosis and patient management.

    Purpose of the Study:

    • To describe the computed tomography (CT) findings of specific post-leukotomy complications.
    • To characterize the imaging appearance of bilateral frontal lobe cysts following frontal leukotomy.

    Main Methods:

    • Retrospective review of computed tomography (CT) scans from patients who underwent frontal leukotomy.
    • Analysis of cyst characteristics including location, size, attenuation values, and contrast enhancement patterns.

    Main Results:

    • CT scans demonstrated bilateral cysts within the frontal lobes in all examined patients.
    • These cysts exhibited attenuation values comparable to cerebrospinal fluid (CSF).
    • No contrast enhancement was observed in the cysts, indicating a lack of active vascularity or breakdown of the blood-brain barrier.

    Conclusions:

    • Bilateral frontal lobe cysts are a potential imaging finding after frontal leukotomy.
    • The cysts' appearance on CT, similar to CSF and without contrast enhancement, aids in differentiating them from other pathologies.
    • These findings contribute to the understanding of long-term sequelae of frontal leukotomy.
