Computed Tomography01:10

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...

Imaging Studies III: Computed Tomography

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...

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

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...

Area of Science:

  • Radiology and Medical Imaging
  • Oncology
  • Biomedical Engineering

Background:

  • Mammography suffers from image superimposition, limiting its diagnostic accuracy.
  • Current breast imaging technologies present various challenges in terms of comfort, cost, and diagnostic detail.
  • There is a need for advanced breast imaging solutions that offer improved visualization and diagnostic capabilities.

Purpose of the Study:

  • To introduce and highlight the advantages of Dedicated Breast Computed Tomography (DBCT) as a novel breast imaging technology.
  • To compare DBCT with existing breast imaging modalities, including mammography and MRI.
  • To explore the potential applications and future directions of DBCT in breast cancer detection and management.

Main Methods:

  • DBCT utilizes isotropic image data for excellent morphologic detail and soft tissue contrast.
  • Postprocessing capabilities include maximum-intensity projection, subtraction imaging, and integration with computer-aided detection/diagnosis algorithms.
  • DBCT can be combined with intravenous contrast, SPECT, or PET for enhanced physiological information.

Main Results:

  • DBCT provides three-dimensional visualization, mitigating superimposition issues inherent in mammography.
  • The technology offers excellent morphologic detail and soft tissue contrast.
  • DBCT is perceived as more comfortable than mammography due to lack of breast compression.
  • Cost is expected to be more reasonable than MRI.
  • DBCT serves as a platform for multimodality imaging and image-guided procedures.

Conclusions:

  • DBCT presents a significant advancement in breast imaging, offering superior visualization and diagnostic potential.
  • Its comfort, cost-effectiveness, and integration capabilities make it a promising alternative to current methods.
  • The DBCT platform holds potential for future applications, including image-guided radiation therapy.
