Imaging Studies IV: Magnetic Resonance Imaging

285
Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

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...

Atomic Nuclei: Magnetic Resonance

1.2K
The number of nuclear spins aligned in the lower energy state is slightly greater than those in the higher energy state. In the presence of an external magnetic field, as the spins precess at the Larmor frequency, the excess population results in a net magnetization oriented along the z axis. When a pulse or a short burst of radio waves at the Larmor frequency is applied along the x axis, the coupling of frequencies causes resonance and flips the nuclear spins of the excess population from the...

Nuclear Magnetic Resonance (NMR): Overview

7.0K
Nuclear magnetic resonance (NMR) is a phenomenon exhibited by certain nuclei that can absorb characteristic radio frequency radiation under certain conditions. NMR has been extensively applied in molecular spectroscopy and medical diagnostic imaging. In both these applications, the molecule or subject under study is placed in a magnetic field and irradiated with radio frequency energy.
NMR spectroscopy generates a spectrum where the characteristic absorption frequencies of the sample are...

Econometric Views (EViews)

594
Econometric Views, often stylized as EViews, is a package that merges statistical analysis with econometric studies. It is designed to provide tools for time series analysis, forecasting, and econometric model simulation. The software originated from MicroTSP software and has evolved significantly since its inception in 1981. The history of EViews is marked by a continuous effort to enhance its computational speed and user interface. It was initially developed for large computing systems but...

Area of Science:

  • Cardiology
  • Medical Imaging
  • Echocardiography

Background:

  • Obtaining optimal right ventricular (RV) apical views with conventional 2D echocardiography is challenging.
  • Standardized RV assessments are crucial for diagnosing and managing various cardiac conditions.

Purpose of the Study:

  • To evaluate the correlation between RV measurements derived from 3D echocardiography focused views (3D-RV-focused) and cardiac magnetic resonance (CMR) imaging.
  • To assess the test-retest reliability and potential bias of unfocused RV views in 3D echocardiography.

Main Methods:

  • A cohort of 47 patients underwent both 3D echocardiography and CMR imaging.
  • A second cohort of 25 patients had repeat 3D echocardiography to assess test-retest characteristics.
  • RV focused and unfocused tomographic views were extracted from 3D datasets for analysis.

Main Results:

  • 3D-RV-focused measurements showed strong associations with CMR-derived metrics.
  • RV fractional area change (RVFAC) from 3D-RV-focused views strongly correlated with CMR ejection fraction (RVEF) (r=0.92).
  • RV end-systolic area (RVESA) from 3D-RV-focused views strongly correlated with CMR volume (r=0.87). Unfocused views underestimated RVESA by 10%.

Conclusions:

  • Standardized RV focused views obtained via 3D echocardiography demonstrate strong agreement with CMR measurements.
  • This 3D approach offers improved reproducibility for RV 2D measurements, potentially enhancing clinical utility.
