Brain Imaging

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).

Imaging Studies I: CT and MRI

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Computed Tomography

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...

Issues And Trends In Healthcare Delivery System

Issues And Trends In Healthcare Delivery System

The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Area of Science:

Radiology
Medical Imaging
Artificial Intelligence

Background:

Computer-aided diagnosis (CAD) is increasingly integrated into routine radiology.
CAD systems assist radiologists by providing a "second opinion" on image interpretations.
Key components include image processing, feature analysis, and classification using tools like artificial neural networks (ANN).

Purpose of the Study:

To explore current computer-aided diagnosis processes, including artificial intelligence applications in radiology.
To discuss the temporal subtraction technique for enhancing interval changes in sequential images.
To review the application and impact of artificial neural networks in medical diagnosis.

Main Methods:

Temporal subtraction for enhancing interval changes and suppressing normal structures between successive images.
Nonlinear image warping to reduce misregistration artifacts in temporal subtraction.
Application of artificial neural networks (ANN) for computerized differential diagnosis.

Main Results:

Temporal subtraction, initially developed for chest radiographs, has been applied to CT and bone scans.
Observer studies showed improved reading times and diagnostic accuracy for bone scans using temporal subtraction.
ANN has been widely used since 1990 for diagnosing various diseases across different imaging modalities.

Conclusions:

Computer-aided diagnosis, incorporating techniques like temporal subtraction and ANN, is becoming standard in clinical radiology.
These AI-driven tools enhance diagnostic accuracy and efficiency.
Integration into picture archiving and communication systems is anticipated for widespread adoption.
