Imaging Studies III: Computed Tomography

387
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...

Computed 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...

Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.

Fixed Action Patterns

17.7K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Design Example: Traverse Angle Computations

342
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...

Area of Science:

  • Neurosurgery
  • Radiology
  • Global Health

Background:

  • Hydrocephalus presents a significant global health challenge, particularly in low-income countries where diagnostic resources are scarce.
  • Limited data exists on the prevalence and patterns of hydrocephalus in resource-limited settings.

Purpose of the Study:

  • To analyze the patterns of hydrocephalus using computed tomography (CT) scans in a rural, low-income setting in Haiti.
  • To understand the demographics, radiologic findings, and etiologies of hydrocephalus in this population.

Main Methods:

  • Retrospective analysis of 3614 head CT scan reports performed between July 2013 and January 2016.
  • Identified cases of hydrocephalus based on specific radiologic terminology in reports.
  • Extracted demographic, clinical indication, and radiologic findings data.

Main Results:

  • Hydrocephalus was identified in 3.5% of CT scans (119 cases), with 39% occurring in pediatric patients.
  • Noncommunicating hydrocephalus was predominant (55%), often caused by intraventricular hemorrhage or brain tumors.
  • A significant majority (95%) of identified cases indicated a potential need for neurosurgical intervention.

Conclusions:

  • Hydrocephalus is a prevalent condition in this rural, low-income setting, frequently noncommunicating and associated with surgically treatable intracranial lesions.
  • Findings underscore the critical need for enhanced neurosurgical capacity and resources in low-income countries.
  • This data can guide research, policy, and clinical collaborations to improve hydrocephalus management globally.
