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...

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...

Electron Microscope Tomography and Single-particle Reconstruction

Electron Microscope Tomography and Single-particle Reconstruction

Transmission electron microscopy (TEM) can be used to determine the 3D structure of biological samples with the help of techniques such as electron microscope tomography and single-particle reconstruction. While single-particle reconstruction can examine macromolecules and macromolecular complexes in vitro conditions only, tomography permits the study of cell components or small cells in vivo.
Electron Tomography
Electron tomography can be performed either in TEM or STEM (scanning transmission...

Positron Emission Tomography

Positron Emission Tomography

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 being...

Imaging Studies II: Positron Emission Tomography and Scintigraphy

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.

Area of Science:

Radiology
Medical Imaging

Background:

Spiral computed tomography (CT) technology has advanced significantly, from single-slice to 64-row multidetector systems.
These advancements provide datasets with exceptional spatial and temporal resolution.

Purpose of the Study:

To emphasize the critical role of data utilization in computed tomography (CT) imaging.
To highlight the necessity of advanced postprocessing techniques for maximizing information extraction from CT datasets.

Main Methods:

Supplementing traditional axial interpretation with 3-dimensional (3D) rendering of CT volumes.
Employing multiplanar reconstruction (coronal, sagittal, oblique planes) and 3D mapping (volume rendering, maximum intensity projection) for both arterial and venous phases.

Main Results:

Comprehensive postprocessed CT studies yield the greatest amount of information.
Advanced visualization techniques enable highly accurate clinical decision-making.

Conclusions:

Postprocessing of computed tomography (CT) data is a mandatory requirement, not merely an option.
This is particularly crucial with the advent of 64-row multidetector CT and beyond.
