Implantation and Monitoring by PET/CT of an Orthotopic Model of Human Pleural Mesothelioma in Athymic Mice07:54

Implantation and Monitoring by PET/CT of an Orthotopic Model of Human Pleural Mesothelioma in Athymic Mice

7.3K
This article describes the generation of an orthotopic mouse model of human pleural mesothelioma by implantation of H2052/484 mesothelioma cells into the pleural cavity of immunocompromised athymic mice. The longitudinal monitoring of the development of intrapleural tumors was assessed by non-invasive multimodal [18F]-2-fluoro-2-deoxy-D-glucose positron emission tomography and computed tomography...

Here we will demonstrate the fundamentals of single-photon emission computed tomography/computed tomography (SPECT/CT) imaging using mice. The technique involves injecting a radionuclide into a mouse, imaging the animal after it is distributed throughout the body, and then reconstructing the produced images to create a volumetric dataset. This can...

Inertial Frames of Reference01:03

Inertial Frames of Reference

8.6K
Newton’s first law is usually considered to be a statement about reference frames. It provides a method for identifying a special type of reference frame: the inertial reference frame. In principle, we can make the net force on a body zero. If its velocity relative to a given frame is constant, then that frame is said to be inertial. So, by definition, an inertial reference frame is a reference frame where Newton's first law holds valid. Newton's first law applies to objects with...

Non-inertial Frames of Reference01:27

Non-inertial Frames of Reference

7.1K
A reference frame accelerating or decelerating relative to an inertial frame is a non-inertial frame. To help understand this, consider what taking off in an airplane, turning a corner in a car, riding a merry-go-round, and the circular motion of a tropical cyclone all have in common. All these systems are accelerating, decelerating, or rotating relative to the Earth; hence, they all are non-inertial frames. All these systems exhibit inertial forces, which merely seem to arise from motion,...

Chemical Shift: Internal References and Solvent Effects

1.3K
In an NMR sample, precise measurement of the absolute absorption frequencies of nuclei is difficult. A standard internal reference compound is added, and the frequency difference between the reference signal and sample signals is measured.
The internal reference compound generally used in NMR spectroscopy is tetramethylsilane (TMS). TMS is preferred because it is chemically inert, soluble in NMR solvents, and easily removable. Also, the highly shielded methyl protons in TMS yield an intense...

Area of Science:

  • Medical Imaging
  • Radiology
  • Radiation Protection

Background:

  • Diagnostic Reference Levels (DRLs) are essential for optimizing radiation doses in medical imaging.
  • Paediatric CT scans require specific attention due to the radiosensitivity of children.
  • Limited data exists on current DRLs for paediatric CT in Jordan.

Purpose of the Study:

  • To investigate the current status of DRLs for paediatric CT examinations in Jordan.
  • To compare radiation dose metrics (CTDIvol and DLP) across different Jordanian hospitals and age groups.
  • To benchmark Jordanian DRLs against international standards.

Main Methods:

  • Data collection of volume CT dose index (CTDIvol) and Dose Length Product (DLP) from 4 Jordanian hospitals/imaging centres.
  • Analysis of dose data for paediatric brain, chest, abdominopelvic, and CAP CT scans.
  • Comparison of measured doses with international DRLs and across different age groups (<1, 1-4, 5-10, 11-18 years).

Main Results:

  • Significant variations in CTDIvol and DLP were observed between different CT scanners within Jordan, with dose differences up to four-fold.
  • DLP values in Jordan were found to be relatively high compared to international DRLs.
  • CTDIvol values in Jordan were comparable to international levels, suggesting protocol-driven variations.

Conclusions:

  • There is a need to optimize paediatric CT radiation doses in Jordan due to observed variations.
  • Differences in protocols and equipment are likely contributors to the dose disparities.
  • Establishing and adhering to national DRLs is recommended to reduce unnecessary radiation exposure in paediatric patients.
