Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation01:26

Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation

964
Inductively coupled plasma (ICP) is the common plasma source used in atomic emission spectroscopy (AES), a technique that detects and analyzes various elements in a sample. This method is often called inductively coupled plasma atomic emission spectroscopy (ICP-AES).
There are three main types of inductively coupled plasma atomic emission spectroscopy  (ICP-AES) instruments: sequential, simultaneous multichannel, and Fourier transform instruments, with the latter being less commonly used....

Double Resonance Techniques: Overview

850
Double resonance techniques in Nuclear Magnetic Resonance (NMR) spectroscopy involve the simultaneous application of two different frequencies or radiofrequency pulses to manipulate and observe two distinct nuclear spins. One important application of double resonance is spin decoupling, which selectively suppresses coupling with one type of nucleus while observing the NMR signal from another nucleus, simplifying the spectrum and enhancing resolution.
Spin decoupling is usually achieved by...

Interpreting ¹H NMR Signal Splitting: The (n + 1) Rule

3.1K
In the AX proton spin system, proton A can sense the two spin states of a coupled proton X, resulting in a doublet NMR signal with two peaks of equal (1:1) intensity. When proton A is coupled to two equivalent protons (AX2 spin system), the spin states of each X can be aligned with or against the external field, creating three possible scenarios. This results in a 1:2:1  triplet signal, where the central peak corresponds to the chemical shift of A and is twice as large or intense as the...

¹³C NMR: ¹H–¹³C Decoupling01:04

¹³C NMR: ¹H–¹³C Decoupling

2.1K
The probability of having two carbon-13 atoms next to each other is negligible because of the low natural abundance of carbon-13. Consequently, peak splitting due to carbon-carbon spin-spin coupling is not observed in spectra. However, protons up to three sigma bonds away split the carbon signal according to the n+1 rule, resulting in complicated spectra.
A broadband decoupling technique is used to simplify these complex, sometimes overlapping, signals. Broadband decoupling relies on a...

Area of Science:

  • Magnetic Resonance Imaging
  • Neuroimaging
  • Biomedical Engineering

Background:

  • Multi time-point pseudo-continuous arterial spin labelling (pCASL) with Look-Locker EPI enables blood kinetics analysis.
  • Signal relaxation limits the number of slices in conventional pCASL.
  • Efficiently sampling blood kinetics is crucial for quantitative perfusion imaging.

Purpose of the Study:

  • To implement and evaluate a multiband excitation technique for accelerating multi time-point pCASL.
  • To increase the number of readout slices in multi time-point pCASL without extending acquisition time.

Main Methods:

  • Incorporation of multiband excitation and 2-fold in-plane parallel imaging into Look-Locker EPI for pCASL.
  • Performance comparison between multiband and single-band techniques in four healthy subjects at 3T.
  • Analysis of quantitative perfusion maps derived from labelling with and without flow suppression gradients.

Main Results:

  • Multiband accelerated pCASL successfully tripled readout slices (18 vs. 6) within the same acquisition time (6.23 min).
  • Perfusion maps from the multiband technique showed good agreement with the conventional single-band method.
  • Multiband acceleration resulted in a minor SNR loss but maintained quantitative accuracy.

Conclusions:

  • Multiband excitation is a viable technique to enhance volumetric coverage in multi time-point pCASL.
  • This acceleration allows for comparable quantitative perfusion data acquisition in significantly reduced time.
  • The method holds promise for improving the efficiency of dynamic perfusion imaging.
