Can you name some recent top stories in magnetic resonance imaging?

Magnetic resonance imaging (MRI) is a method and technology that uses radio frequency electromagnetic waves to excite a substance that contains a non-zero spin nucleus in a magnetic field. It uses induction coil detection technology to collect resonance signals and reconstruct the image to form a magnetic resonance image. The principle was that the basic units of the various substances that made up the human body were molecules. The basic units of molecules were atoms, and the nuclei with neutrons had spin properties. The human body was placed in an external magnetic field, and a radio frequency pulse of a specific frequency was applied to stimulate the hydrogen nuclei in the human body to resonate and absorb, changing the spin state. After the radio frequency stopped, the nucleus released energy to produce a radio signal. After being processed by the computer system, it was displayed on the monitor as an image. MRI could obtain cross-section tissue images from multiple angles and even three-dimensional directions. The signal contrast between different tissues was strong, and it could better eliminate signal interference and had good resolution. Compared with CT, MRI images could provide clearer anatomical details without the damage of ionising radiation. It could be used for multi-directional cross-section examination. It had the advantages of high sensitivity, multi-directional, multi-parameters imaging, and high soft tissue resolution. It could display the characteristics of blood vessels and tissue structures without contrast agents. However, people with metal objects in or on the surface of their bodies were not suitable for this examination because it would affect the results of the examination. It could also cause damage to the machine or bring danger to the patient. For example, if a person was equipped with a cardiac pacemakers, the pacemakers might malfunction. All metal objects must be removed before the MRI examination. If there are medical implanted devices in the body, the MRI technician must be informed, such as pacemakers. During the examination, you need to lie on the table outside the scanner. If the scanner is noisy, you may need to wear earplugs or headphones, and you have to keep still to make the image clear. Most of the time, a closed scanner would be used. Some areas also had an open scanner, but the image quality of an open scanner might be worse. The technicians operated in the next room and could talk through the walkie-talkie. MRI technology had developed rapidly and was widely used to examine all parts of the body except the digestive tract and the peripheral parts of the lungs. It could not only display the human body's morphological structure, but also display biochemical information at the atomic nucleus level. It could also display the functional status of certain organs. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Another possibility is that there are top stories in the field of technology. For instance, a major tech company might have launched a revolutionary new product, like a super - efficient battery that could change the game for electric vehicles. This would surely be among the recent top stories as it has a significant impact on various industries and the future of transportation.

One story was about a state where a bipartisan commission was formed to address gerrymandering. This was significant because it showed that politicians from different parties can come together to try and create a more fair system of drawing district boundaries. The commission's work and the challenges it faced in trying to create balanced districts were widely reported.

Recently, the rebuilding efforts in areas affected by previous conflicts might be a top story. After destruction, the Palestinian people, with the help of some international aid, are trying to reconstruct their homes and infrastructure.

One recent story might be about their new album releases. They always generate a lot of buzz when they come out with new music. Another could be their recent tours. Fans are always excited to see them perform live. And there might be stories about any new music videos they've released, as they are known for their creative and visually appealing videos.

There could also be a story about Foxconn's workforce management. Given its large number of employees, any changes in labor policies, such as improving working conditions, providing more training opportunities, or dealing with labor shortages, can be considered a top story. These aspects are closely watched by the public, investors, and industry analysts.

The #MeToo movement was also driven in part by investigative journalism. Reporters interviewed numerous women who had experienced sexual harassment and assault in various industries. This led to a global reckoning with the issue and changes in workplace policies.

There have also been stories about Broadway's efforts to become more inclusive. Productions are now casting more diversely, both in terms of race and gender. This has led to some really interesting and groundbreaking shows that are making headlines for their inclusive casting choices.

Well, recently there was a case of a well - known politician being involved in a corruption scandal, which is a major crime story. Also, the increasing number of carjackings in some urban areas has been a concerning crime story lately. And then there was a case where a group was caught running an illegal gambling ring that had ties to organized crime.
