IR Frequency Region: Fingerprint Region01:03

IR Frequency Region: Fingerprint Region

1.9K
IR spectra are divided into two main regions: the diagnostic region and the fingerprint region. The diagnostic region of the spectrum lies above 1500 cm−1. The absorptions resulting from single-bond vibrations of the N–H, C–H, and O–H stretch at higher wavenumbers and appear on the left side of the spectrum. The stretching absorptions of the C≡C and C≡N occur between 2100–2300 cm−1. In contrast, those arising from stretching absorptions of the...

Structural Joints: Synovial Joints

6.5K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

Structural Joints: Fibrous Joints01:03

Structural Joints: Fibrous Joints

3.6K
Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

Structural Joints: Cartilaginous Joints

3.9K
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...

Joints

35.5K
Joints, also called articulations or articular surfaces, are points at which ligaments or other tissues connect adjacent bones. Joints permit movement and stability, and can be classified based on their structure or function.
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
Fibrous Joints Are Immovable
The bones of a...

Introduction to Joints

4.7K
The adult human body usually has 206 bones, and except for the hyoid bone in the neck, each bone is connected to at least one other bone. Joints are the location where bones come together. Many joints allow for movement between the bones. At these joints, the articulating surfaces of the adjacent bones can move smoothly against each other. However, the bones of other joints may be joined by connective tissue or cartilage. These joints are designed for stability and provide little or no...

Area of Science:

  • Cardiovascular Imaging
  • Medical Physics
  • Biomedical Engineering

Background:

  • 0.55T MRI systems present opportunities for wider access to cardiac magnetic resonance imaging.
  • Exploring novel techniques like MR Fingerprinting (MRF) is crucial for optimizing low-field MRI performance.

Purpose of the Study:

  • To evaluate the feasibility of cardiac MR Fingerprinting (MRF) at 0.55T.
  • To assess the efficacy of deep image prior (DIP) reconstruction in mitigating noise for 0.55T cardiac MRF.

Main Methods:

  • Phantom and prospective in vivo studies were conducted using a 0.55T MRI system.
  • MR Fingerprinting (MRF) was implemented and compared against conventional Modified Look-Locker (MOLLI) and T2-prepared balanced steady-state free precession (T2-bSSFP) sequences.
  • Reconstruction methods included a low-rank technique (SLLR-MRF) and a deep image prior approach (DIP-MRF).

Main Results:

  • DIP-MRF demonstrated comparable T1 mapping accuracy to conventional methods and significantly lower T2 values.
  • Image quality scores were highest for DIP-MRF (T1: 3.8, T2: 4.1), followed by conventional mapping (T1: 3.4, T2: 3.9), and lowest for SLLR-MRF (T1: 2.3, T2: 2.9).
  • DIP-MRF achieved significantly lower myocardial standard deviations for both T1 and T2 compared to SLLR-MRF.

Conclusions:

  • Cardiac MR Fingerprinting (MRF) is feasible on a commercial 0.55T system.
  • Deep image prior reconstruction is a key enabler for high-quality cardiac MRF at 0.55T by effectively reducing image noise.
  • This advancement holds promise for expanding the utility of low-field cardiac MRI.
