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...

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

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...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Area of Science:

  • Medical Imaging
  • Radiology
  • Biomedical Engineering

Background:

  • Magnetic resonance (MR) imaging is crucial for pediatric diagnostics.
  • Faster and higher-resolution imaging techniques are needed to improve pediatric MR scans.
  • Current methods face challenges in delineating fine anatomical structures in children.

Purpose of the Study:

  • To develop and assess a novel MR imaging method combining parallel imaging and compressed sensing.
  • To demonstrate the feasibility of this combined technique in a pediatric clinical setting.
  • To evaluate its potential for enhancing image quality and spatial resolution.

Main Methods:

  • A pseudorandom k-space undersampling pattern was integrated into a 3D gradient-echo sequence.
  • Compressed sensing (CS) nonlinear reconstruction was used to reconstruct images from undersampled data, removing aliasing.
  • The method was applied to 34 pediatric patients undergoing cardiovascular, abdominal, and knee MR imaging.

Main Results:

  • Images reconstructed with compressed sensing were significantly preferred over those from traditional parallel imaging.
  • Compressed sensing yielded higher image quality ratings and superior delineation of anatomical structures (P < .001).
  • The technique demonstrated feasibility in a clinical pediatric environment.

Conclusions:

  • The combination of parallel imaging and compressed sensing is a feasible and effective approach for pediatric MR imaging.
  • This method holds promise for achieving higher spatial resolution and/or faster scan times.
  • It addresses the critical need for improved anatomical structure delineation in pediatric MR examinations.
