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...

Radiological Investigation I: X-ray and CT

Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and the...

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...

Imaging Studies for Cardiovascular System IV: CMRI

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Summary

This summary is machine-generated.

For CR-mammography, 1.0d gradation processing produced superior imaging sensitivity for masses and calcifications compared to the recommended 1.2G. This suggests 1.0d may be a more effective setting for detecting breast cancer abnormalities.

Area of Science:

Medical Imaging
Radiology
Digital Image Processing

Background:

Gradation processing is crucial for creating diagnostic quality CR images.
The optimal gradation processing for CR-mammography, specifically for detecting masses and calcifications, requires further investigation.

Purpose of the Study:

To compare the imaging sensitivity of 1.0d and 1.2G gradation processing in CR-mammography.
To determine the ideal gradation processing for visualizing breast cancer lesions.

Main Methods:

A comparative study was conducted on 18 breast cancer cases.
CR images were acquired using both 1.0d and 1.2G gradation processing settings.
Image quality for masses and calcifications was evaluated between the two settings.

Main Results:

The 1.0d gradation processing setting demonstrated superior performance in imaging breast masses.
All 6 cases with calcifications showed improved visualization with the 1.0d setting.
The higher declination (gamma) of the 1.0d setting contributed to enhanced image sensitivity.

Conclusions:

1.0d gradation processing is more effective than the generally recommended 1.2G for CR-mammography.
This finding suggests a potential improvement in the detection of breast cancer abnormalities through optimized gradation settings.
