Magnetic Resonance Imaging01:24

Magnetic Resonance Imaging

5.1K
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 I: CT and MRI

242
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...

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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

92
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Area of Science:

  • Radiology
  • Oncology
  • Medical Imaging

Background:

  • Breast dynamic contrast-enhanced MRI (DCE-MRI) is highly sensitive for breast cancer detection.
  • Current screening MRI is primarily for high-risk patients, but could benefit intermediate-risk and dense-breasted women.
  • Reducing scan and interpretation times can enhance cost-effectiveness and accessibility.

Purpose of the Study:

  • To review current breast MRI screening indications.
  • To examine standard breast DCE-MRI techniques.
  • To explore alternate, time-efficient screening MRI protocols.

Main Methods:

  • Review of existing literature on breast MRI screening.
  • Discussion of standard breast DCE-MRI.
  • Exploration of abbreviated breast MRI (Ab-MRI), ultrafast MRI, and diffusion-weighted imaging (DWI).

Main Results:

  • Ab-MRI shortens scan time but lacks kinetic information.
  • Ultrafast MRI captures kinetic data within the first minute post-contrast.
  • Noncontrast DWI shows potential for detecting mammographically occult cancers.

Conclusions:

  • Alternate breast MRI protocols can decrease scan and interpretation times.
  • These advancements may expand MRI screening accessibility.
  • Optimized MRI techniques hold promise for broader breast cancer screening applications.
