Computed Tomography01:10

Computed Tomography

7.3K
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...

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...

Positron Emission Tomography

6.3K
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...

Area of Science:

  • Oncology
  • Radiology
  • Medical Imaging

Background:

  • Breast cancer is the most common malignancy among Indian women.
  • Mammography aids early detection but has limitations due to its 2D nature, leading to missed diagnoses.
  • Digital Breast Tomosynthesis (DBT) was approved by the FDA in 2011 as a supplemental screening tool.

Purpose of the Study:

  • To review the principles of Digital Breast Tomosynthesis (DBT).
  • To comprehensively study the existing literature on DBT in breast cancer screening.
  • To highlight DBT's advantages over traditional mammography.

Main Methods:

  • Review of scientific literature on Digital Breast Tomosynthesis (DBT).
  • Analysis of DBT's technical principles and imaging acquisition.
  • Evaluation of studies reporting DBT's performance in screening and diagnostics.

Main Results:

  • DBT provides a 'third' dimension by acquiring multiple low-dose images, allowing layer-by-layer visualization of breast tissue.
  • DBT improves cancer detection rates.
  • DBT reduces recall rates and false-positive findings through enhanced lesion characterization.

Conclusions:

  • Digital Breast Tomosynthesis (DBT) offers significant improvements in breast cancer detection and diagnostic accuracy.
  • DBT addresses limitations of 2D mammography, leading to better patient outcomes.
  • The review underscores the value of DBT as an advanced screening modality.
